7 Metal Roofing Pros and Cons to Consider
Photo: istockphoto.com
Rain on a tin roof proves so soothing that it can be found on white noise machines and meditation apps alike, but that’s not the only reason (nor one of the top!) for its popularity among today’s homeowners. Growing numbers of people are installing metal roofs in both new construction and roof replacement projects. In fact, McGraw-Hill Construction and Analytics estimates that 750,000 U.S. homeowners chose metal roofing for their residences as of 2015. That number indicates an 11 percent share of the roofing market—second choice only to asphalt shingles.
Curious why this construction material has won over so many homeowners? See the complete list of metal roofing pros and cons below. Weigh them carefully, and you may find that you, too, could benefit from this reliable roofing overhead.

PRO: Metal roofs are durable and long-lasting.
At the top of the list of metal roofing “pros,” the material’s long lifespan is why most homeowners make the switch in either a re-roofing or new construction. Indeed, that recent McGraw-Hill survey found that 26 percent of homeowners cited longevity as their primary reason for investing in metal and another 22 percent said they were swayed by its strength. A properly installed metal roof typically will last as long as the house, with an expected lifespan of 40 to 70 years and, often, a 30- to 50-year manufacturer’s warranty to boot. (By contrast, traditional asphalt roofing typically lasts 12 to 20 years.) Thanks to the material’s unique durability, you can count on it to withstand the elements—including gusts of wind up to 140 miles per hour—and not corrode nor crack thanks to rust-proof coatings.
CON: Metal roofs are expensive.
The many years of service that a metal roof promises come at a high cost.
This material can run from $120 to $900 per 100 square feet (or one “square” of material), according to Home Advisor’s Guide to Roofing Costs. Though this range is comparable to the costs of other premium roofing products, higher-end metals run as much as 10 times the cost of asphalt shingles. Then, not only do materials come with high price tags, but the installation labor is also more expensive than what you’d pay for other types of roofing because of the specialized training, knowledge, tools, and equipment it entails. That’s not to say that homeowners won’t recoup money on your initial investment, though. While you might have to pay for replacing a conventional asphalt shingle roof several times over the lifespan of your home, a high-quality metal roof could very likely be the last roof your home will ever need. It’s as the saying goes, “You get what you pay for.”

PRO: Metal roofs are environmentally friendly.
Traditional asphalt shingles are a petroleum product and, as such, increase dependency on fossil fuels.
Plus, they require replacement every 15 to 20 years, which means that nearly 20 billion pounds of old asphalt shingles are sent to U.S. landfills every year, according to the Environmental Protection Agency.

Metal roofs, on the other hand, are considered a more sustainable alternative for a number of reasons. For starters, they consist of at least 25 percent recycled materials and are 100 percent recyclable themselves. (Steel roofing can be recycled repeatedly without loss of strength!) Metal roofing also provides an ideal platform for homeowners who want to embark various eco-conscious initiatives, including solar panels and systems for harvesting rainwater. Finally, in some re-roofing projects, a metal roof is so light—roughly one-third the weight of asphalt—that it can be installed directly overtop asphalt shingles without overburdening the roof’s structural support. This strategic move saves the effort and sheer waste of ripping off the old roofing and sending it to a landfill.
CON: Metal roofs can be dented.
Although today’s metal roofs are designed to withstand decades of abuse from extreme weather—including heavy snow and ice, both of which slide right down the slick metal slope rather than linger and cause leakage—some metal can still be dented by large hail or falling branches. Depending on the type of roof, you may not even be able to walk on the metal shingles without damaging them. If these drawbacks sound more like dealbreakers, rest assured that they can be sidestepped altogether if you choose the right shingle (preferably one that comes with a guarantee to never dent!). Some types of metal are just stronger than others. Aluminum and copper, for example, are both softer and therefore more prone to this type of damage than, say, steel.
PRO: Metal roofs are energy-efficient.
Money spent on the installation of a metal roof can be recouped from the savings in monthly cooling and heating costs thanks to this type of roof’s reflective properties.
Metal roofs reflect solar radiant heat instead of absorbing it, which—yearround, but especially during the long days of summer—can reduce cooling costs by as much as 25 percent, according to the Metal Roofing Alliance. Furthermore, some metal roofing comes coated with special reflective pigments to minimize heat gain, keeping occupants comfortable without having to crank up the air conditioner.

CON: Metal roofs can be noisy.
Though listed here as a “con,” this particular drawback doesn’t need to be a given. Sure, metal could be noisier than other types of roofing, especially during a heavy rain or thunderstorm, but extra layers of solid sheathing or insulation installed beneath it will typically minimize the sound heard inside. (That said, these layers will need to be factored into the overall cost of the roof.)
PRO: Metal roofs are stylish.
Today’s metal roofs are a far cry from the corrugated tin barns of the bucolic past—indeed, now you can choose from tin, zinc, aluminum, copper, or galvanized steel, in a dizzying array of colors, finishes, and even shapes! Their variety surpasses that of the much more conventional asphalt shingle.
While asphalt might offer 15 to 20 color choices, modern metal roofing comes in more than 100 different colors, including standard, premium, and custom hues. Steel and aluminum, the two most common metals used in residential roofing, are both designed to hold paint finishes well.
Seven out of 10 homeowners living under metal roofs designed theirs with the traditional vertical ribbed panels or “standing seam” construction, but metal roofing is not short on style options either. Fans of more traditional profiles can opt for a metal shingle manufactured to resemble wood shakes, slate or clay tiles, or any other number of designs instead. The metal doesn’t have to stand out like a sore thumb to do its job; rather, it can mimic nearly any look using multiple-layer factory finishes that ensure that the appearance is not only beautiful but long-lasting and durable.

Pros and Cons of Metal Roofs for Your Home
Whether you’re buying a home with one or thinking of installing, here’s what to know.
Whether you’re putting a roof on a new home, or your existing roof requires a total makeover, there are many materials available. But no matter what roof style you have, metal roofs can be an attractive option because of their longevity, minimal maintenance and energy efficiency. Material choices include steel (galvanized, galvalume or weathering), aluminum, copper, zinc and tin. Product types are vertical seam, pre-formed panels and granular coated panels. Style choices allow you to have the look of shingles, slate, tile, shakes or vertical panels. Make sure your metal roofing product is tested, labeled and listed with a testing organization such as UL, FM Approvals or Intertek to meet rigorous wind, fire and impact resistance rating requirements. Please also remember that installation can vary from geographic location, manufacturer guidelines and as a result of local building code requirements.
Advantages of metal roofs
Metal roofs offer many benefits, including:
- Longevity.
Metal roofs can last 40-70 years, depending on the material. Traditional asphalt roofing materials have an estimated life expectancy of roughly 12-20 years. - Durability. If installed correctly, some metal roofs can sustain wind gusts up to 140 miles per hour, will not corrode or crack and may be impact-resistant (depending on which product you choose). In addition, metal roofs don’t need the periodic costly maintenance that other roofing materials often require. However, they should be inspected periodically to make sure no repairs are required.
- Safety. Metal roofs will not spark and ignite into flames during a wildfire or lightning strike.
- Energy efficiency. Metal roofs reflect the suns UV and infrared light rays that contribute to roof surface radiant heat, which can result in a 10-25% reduction in cooling costs.
- Environmentally friendly. Metal roofs not only have 25-95% recycled content, depending on the material used, but are also 100% recyclable at the end of their life as a roof. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream — up to 20 billion pounds per year.

Despite their many advantages, metal roofs have some potential drawbacks.
- Affordability. Metal roofs can be as much as two or three times more expensive than other roofing materials. While the life of a metal roof is much longer, investing in a metal roof only makes sense if you plan to stay in your home long enough to enjoy the cost benefits.
- Noisiness. Metal roofs may be more noisy during a heavy rain or hailstorm than other products depending on the type of decking used during installation (spaced or solid). Adding more attic insulation can sometimes solve this problem, but that may increase costs.
- Expansion, contraction and fasteners. Metal roofing material assemblies that are attached as large panels are designed to expand and contract as they warm and cool. However, both exposed and concealed fasteners have varying lifespans. Depending on the climate, neoprene washers and the screws used during installation may degrade and become dislodged over time.
- Inconsistency of color match. If a repair is required or a home extension is added years later, it may be difficult to find an exact match to the existing metal.
- Performance. If water accumulates anywhere on the roof because of poor-quality installation or repair, it can eventually cause serious damage. Low-grade metals may also be thinner gauge and less durable. Some metals rust in certain climates or dent more easily than others during hailstorms or installation.

Metal Roof Benefits
Metal beats out conventional roofing materials in several ways:
Metal Roofing Lasts A Long Time
A properly installed quality metal roof should last from 40 to 50 years, sealing out water, surviving high winds, and easily shedding snow.
The fact that metal is resistant to fire, mildew, insects, and rot pays off big in longevity.
For comparison, the following list shows how long other roof materials are expected to last, according to a study by the National Association of Home Builders (NAHB). Please note that harsh climate conditions, poor workmanship, and damage from severe weather can shorten any roof’s expected life.
- Asphalt shingles—20 years
- Fiber cement shingles—25 years
- Modified bitumen roofing—20 years
- Wood shingles and shakes—30 years
- Tar and gravel (flat roof)—20–25 years
How long does a metal roof last?
Metal roofs can last 50 years, depending on climate conditions, workmanship, or unforeseen damage. About the same as:
- Simulated slate—50 years
- Real slate—50+ years
- Clay/concrete tile roofing—50+ years

Most major metal roof manufacturers back their products for 20 to 50 years.
Products with painted finishes typically have a 30-year limited warranty. Materials finished with extremely durable resin-based polyvinylidene fluoride (PVDF) coatings have 50-year warranties. (Kynar® is the trade name of one very popular PVDF coating.)
Metal Roofing Is Lightweight
Metal roofing weighs from 1 to 3 pounds per square foot, depending upon the thickness and profile of the material. It is one of the lightest of all roofing materials. By comparison, here are typical weights of other roofing materials:
- Conventional asphalt shingles — from 2 to 3.5 pounds per square foot
- Textured (architectural) asphalt shingles— from 3.5 to 5 pounds per square foot
- Wood shingles and shakes—from 3.5 to 4.5 pounds per square foot
- Clay or concrete tile—5.5 to 10 pounds per square foot
Because metal roofing is lightweight, you can save on the engineering and building of the supporting structure. In fact, if you’re building a new house or a new addition, you can often downsize or reduce the number of roof support members because of metal roofing’s light weight.
Can Metal Roofing Go Over Existing Shingles?
As long as the existing roof surface and the decking beneath it are sound, flat, and free of rot, metal roofing can usually be applied over the top of one old layer of asphalt shingles. Check local codes and the manufacturer’s specifications before doing this.
Of course, tearing off the old roof so you can start with flat, sound sheathing certainly gives you a much cleaner starting point. But leaving the old roof in place also has advantages. For example, it:
- Decreases labor and haul-off expense of stripping the old roof
- Leaves an extra insulation barrier for increased energy efficiency
- Minimizes the debris and disruption to your home and yard during the project
- Adds additional sound insulation for rain and hail

A Metal Roof Installs Fast
Metal roofing materials are sold as large “standing-seam” sheets or in multiple-shingle sections that are 12 to 36 inches wide.
Standing seam sheets are typically 3 feet wide by 6, 8, 10, 12, 14, and 16 feet long. You can also get custom sizes.© Ronstik | Dreamstime
An accomplished contractor can install these quickly. If your roof is stripped off and a storm is on the way, shortening the installation process by a day or two may offer a critical advantage. Obviously, there is also considerable cost savings if you can ease and shorten the duration of roof installation.
Metal Roofing Doesn’t Catch Fire
Because metal roof materials are noncombustible, they typically have a Class A fire rating (the most fire-resistant rating). Flying sparks and embers will not set them on fire.
Just be aware that part of a roof’s overall classification depends on materials beneath the surface that could ignite in intense heat, too. Most metal roofs applied over a combustible material such as wood shingles have a lower, Class C rating for this reason. (See notes under “Metal Roofing Drawbacks” regarding problems in the event of a house fire.
)
Metal Surfaces Reflect Heat
Metal reflects radiant heat from the sun, minimizing midday heat gain. This reflective characteristic means you save energy needed for air conditioning during the day. In fact, federal rebates are offered for metal roofing that has appropriate pigmented coatings that meet EnergyStar requirements. You can get a 10% tax credit up to $500 (not including labor).
Regarding the insulation value of metal roofing in both heat and cold: Though the material itself is low in insulation R-value, metal roofing can be applied over foam insulation that has very high R-values. In addition, many systems utilize a dead-air space between the metal surface and roof deck beneath it to minimize heat transfer, increasing energy efficiency.
Metal Panels Can Go On Low-Pitched Roofs
Most metal roofing materials can be installed on gently pitched roofs without leaking. Minimum roof pitch for metal shingles is typically 3-in-12—this means the roof rises 3 inches for each horizontal foot.
Some standing-seam roofing can be used on 2-in-12 roof pitch or, in some cases, even as low as 1-in-12.
In comparison, most asphalt or roof shingles can’t be used on a roof with a lower pitch than 3-in-12 (in some cases, 4-in-12) and materials such as tile require a slope that is 4-in-12 or steeper.
Metal Is Great At Shedding Snow & Rain
Metal roofing is practically impervious to rain and snow because of the way the panels interlock and because the surfaces are hard and slippery. In addition, dark tones of metal roofing quickly warm to the sun, encouraging snow melt.Metal roofing is great in snow country because it is fire resistant, lightweight, and excellent at shedding snow. The panels are applied over dense foam insulation to maintain high R-values. Dark surfaces warm in the sun to aid in quickly melting snow. ©Zsolt Biczo / Shutterstock
Steel Roofing Is Environmentally Friendly
Manufacturing asphalt uses petroleum and fossil fuels. Also, asphalt roofs require replacement every 15 to 20 years, so nearly 20 billion pounds of old asphalt shingles are dumped in US landfills every year, according to the Environmental Protection Agency.
A Metal Roof Stands Up to Tornadoes & Hurricanes
“Many metal roofing systems have been tested and proven to withstand winds in excess of 140 miles an hour, which is the equivalent to an F2 tornado and provide protection against impact damage from debris.” say’s Todd Miller, Vice Chairman of the Metal Roofing Alliance.
According to the Palm Beach Post, metal roofs proved to be the most hurricane-resistant. “If the roofers used the correct attachment method, either screws or clips, the wind will have a difficult time getting underneath metal roof panels.”
Metal Roofing Drawbacks & Myths
Though metal roofing offers many pluses, a few drawbacks are worthy of mention. For the most part, metal roofing manufacturers have improved their products to address or solve many of these concerns, so it’s important to separate the myths from the drawbacks that are real.
Is Metal Roofing Noisy?
Yes, it will probably be noisier than living beneath a thick slate or tile roof in a heavy rainstorm or hailstorm.
But the idea of noise being a problem may be more myth than reality. It depends on construction.
Metal shouldn’t be noisier than thinner materials such as asphalt or wood shingles. The fact is that rain and hail can drum on any thin membrane.
But noise can be controlled both by using quality materials that have structural barriers to minimize the drumming effect, by applying the metal over sound-deadening insulation and solid plywood sheathing, and—where possible—by having an attic between the roof and your rooms.
Do Metal Roofs Attract Lightning?
This is a myth. Many people assume that because metal conducts electricity, it also attracts it. This really isn’t the case, and many instances have been documented where lightning has struck trees or other high objects located near metal roofs rather than the roofs themselves. Just the same, metal roofs should be grounded by a lightning protection company.
If a metal roof does get struck by lightning, it will disperse the energy and be far less likely to burn than a wood roof.
High Initial Cost—Yes, but…
Okay, you’ve landed on the biggest drawback of metal roofing: initial cost. Metal roofing costs about the same as other premium materials—from about $150 to $600 per square (100 square feet).© Osa855 | Dreamstime
For the sake of comparison, here is a list of typical price ranges for metal roofing and other common roofing materials for an average size home:
- Metal roofing (steel) – $5000 to $13,000
- Metal roofing (copper) – $10,000 to $25,000+
- Asphalt-fiberglass shingles – $4000 to $7000
- Wood shingles and shakes – $10,000 to $20,000
- Concrete tile – $8000 to $23,000
- Clay tile – $12,000 to $30,000+
- Synthetic slate – $12,000 to $30,000
- Natural slate – $18,000 to $60,000+
Because of the material’s long-term durability, the trick is that you ultimately save the difference (and more) if you stay in the house for a long time and you save on seasonal maintenance. Then again, if you plan to move in a couple of years, you probably won’t get a reasonable return on your investment unless your future buyer recognizes the long-term value of the roof.
Add up all materials and labor and divide this sum by the number of years the roofing is expected to last to estimate your roof’s cost per year.
Metal Can Dent
Okay, if a golf ball hits your car, it will leave a dent. If you live in Texas or somewhere that has hail the size of golf balls, the hail will probably dent your metal roof, especially if your roof is made of a soft metal such as copper or aluminum.
If you think heavy hail would be a possibility in your area, choose a roof material that is guaranteed not to dent. Or choose metal roofing shingles, metal roofing shakes, or roofing that has a pattern or ribbed structure that gives it rigidity. Always, choose 24- or 26-gauge steel for maximum durability.
You Should Avoid Walking On Metal Roofs
Though you shouldn’t have to walk on a roof that doesn’t leak, there may be occasions when a plumber needs to snake out a vent pipe or a chimney sweep needs access to the chimney flue. You have to be very careful when walking on most metal roofs—both to avoid damaging or denting the roofing and to keep from slipping off.
You can walk on some metal roofs but not all of them. Whether or not they will dent from foot traffic depends on how the particular product is made and the type of construction supporting it. As you might imagine, metal can be very slippery when wet.
Some painted metal roof finishes can peel, chip, fade, scratch, or chalk, although nearly all premium products are guaranteed for at least 30 years. Walking on some types, particularly those with a granulated-stone surface, may cause surface wear. Installers must be careful not to scratch or dent the roofing during installation, and panels must be treated with care. Unlike conventional roofing, some metal shingle systems are installed from the top down, eliminating the need to walk on them.
Modifying Panels Can Be Difficult
Metal roofing materials installed in large panels are more difficult to replace if damaged than individual shingles. Also, if you remodel or add on to your home 10 or 20 years from now, it may be difficult to match the material.

Installation Is Not Foolproof
Installing a metal roof should be done by someone with plenty of experience. Unlike an asphalt shingle roof, a wood shingle roof—or most other roofing materials—metal roofing is a material that fewer roofers are trained and practiced at installing.
A metal roof must be installed correctly. If it isn’t, you can have major problems with condensation beneath it and/or leaking.
Some manufacturers or distributors require that their products be installed by professional metal roofing contractors who have been accredited by taking a few factory-taught classes.
Roof panels with exposed fasteners are particularly vulnerable to improper installation. If screws attach through the flat surfaces (rather than the raised ridges), rain water can run down the roof and seep into the screw holes. For this reason, special resilient washes must seal around screw heads. If you have this type of roof installed, be sure the manufacturer’s instructions are followed precisely.
With metal roofing systems, it’s generally advised to have qualified specialists do the installation. Dmitry Kalinovsky / Shutterstock.com
To find a good metal roofing contractors, ask friends and neighbors who have had similar roofs installed (though they may be hard to find because metal roofs are relatively uncommon). You can search online sites such as Yelp, HomeAdvisor or Networx. Be sure to check out reviews and look at photos of completed jobs.
Metal Expands & Contracts
Metal expands and contracts as it warms and cools. This can cause the roof to have a wavy effect on hot days or, over time for fasteners to pull loose. To remedy this problem, most new metal roofing products have fastening systems that accommodate movement.
Difficult for Firefighters
Though metal roofs are good at guarding against a fire that approaches from outside a house, such as from flying sparks and embers, they are not ideal for fires that start inside a house. With a serious house fire, firemen may need to cut through the roof to put out the fire.
This job can be much more difficult and take longer if the house is capped with a metal roof.
Our Summary Recommendations
Most of today’s houses are topped by asphalt fiberglass shingles. In fact 4 out of 5 U.S. roofs are, according to the Asphalt Roofing Manufacturers Association (ARMA). Asphalt-fiberglass has become the dominant American roofing material for many good reasons, as discussed above.
But the popularity of metal roofing is gaining on asphalt. According to Building Design + Construction, in recent years, metal roofing materials “have achieved double-digit market share growth while the market share of asphalt shingles has dropped slightly.” Underscoring this growth, Renee Remey, Executive Director of the Metal Roofing Alliance say’s, “Our research shows that metal roofs are now the second most popular roofing choice among homeowners.” [Citation]
If your budget can afford the initial cost of metal roofing and you plan to stay in your home for a long time, metal can prove to be a very solid investment.
This is particularly true if you live in an area that is prone to storms or wildfires and your home’s architecture lends itself to metal roofing. Bottom line: Metal roofing is a very durable, effective, lightweight choice that is relatively quick to install by professionals.
How Would Metal Roofing Look On Your House?
Another major consideration before seriously considering a metal roof for your home is what it would look like.
Go through photo galleries that metal roof manufacturers offer on their web sites to see houses that resemble your home’s style to get a feel for how metal roofing would look on your house. Also, check out the metal roof visualizer, where you can upload a photo of your house and see what various types of material roofing would look like on it.

Metal roofs are a common choice, both in new construction and when an aging roof needs to be replaced. Metal roofing products can be made from a variety of metals, including galvanized steel, copper, aluminum, or tin, and they can use several different installation systems. There are a great many advantages to a metal roof, but there are also a few disadvantages to consider.
Surprisingly, one of the main fears people hold about metal roofs is without merit: Metal roofs do not attract lightning.
Click Play to Learn About Metal Roofing
Metal Roofs and Lighting
The misconception that metal roofs attract lightning is probably because metal itself is known as a good conductor of electricity, and people, therefore, assume that a metal roof must attract lightning.
In reality, when lightning strikes, it is seeking a path to ground and almost always will strike whatever object is highest in the area that also has a direct path to ground. Your metal roof is not grounded, and thus lighting has no reason to strike it.
A metal roof in no way makes your home more vulnerable or susceptible to lightning strikes.
Some Actual Disadvantages to Metal Roofs
Fear of lightning strikes may be an imaginary problem, but there are a few genuine disadvantages to metal roofs.
The one disadvantage that poses an actual safety risk is the fact that metal roofs are indeed slippery when wet or when covered with snow. It is never a good idea to climb on a metal roof when it is moist or covered with snow. They are so slippery that snow “avalanching” off the roof is a definite hazard in areas that experience heavy snowfalls in winter.
There are some advantages to this, since snow that slips off the roof can’t build up on top of it. People owning asphalt-shingled homes in heavy snow areas may need to rake snow off their roofs in winter, but this is never an issue on a home with metal roofs. But it is also possible for snow to avalanche off a metal roof in such quantities that it can damage decks, shrubs, cars, or even people.
In ski areas notorious for heavy snowfalls, metal roofs are often equipped with snow guards—metal or plastic clips or even horizontal bars mounted to sturdy brackets. Homeowners can employ the same technology to prevent avalanches from the roofs of their homes.
Warning
Even when dry, metal roofs will be more slippery than other types of roofing. If you do need to climb on a metal roof, your first line of protection is a good pair of boots that grip to your type of metal roofing. If you’re doing any significant work on the roof or moving any materials around, you should use standard fall-arrest equipment, including a harness with a safety rope attached to a roof anchor.
Anchors for standing seam metal roofs clamp onto the seams, so you don’t have to drill holes in your roof.
Other disadvantages of metal roofs are not matters of safety, but also issues of convenience or affordability:
- Metal roofs can be loud during rainstorms or hail. It’s a simple fact that any object falling on a metal roof will be louder than objects falling on an asphalt shingle or wood shake roof. Modern installation processes can insulate somewhat against this noise, though, and over time, owners of metal roofs seldom view this as a serious disadvantage.
- Metal roofs can fade in time or may be susceptible to staining.
- If not installed correctly, metal roofs can fail at the seams. It’s essential to have a metal roof installed by a qualified, experienced contractor.
- Metal roofs are considerably more expensive than most other options. When compared to an asphalt shingle roof, for example, a metal roof is at least twice as expensive. Remember, though, that the average metal roof lasts much longer than an asphalt shingle roof.
Advantages Greatly Outweigh the Drawbacks
Metal roofs continue to grow in popularity, and one of their “disadvantages” actually turns out to be an advantage when viewed from the big picture. Although initially much more expensive than an asphalt shingle roof (for example), a metal roof lasts much, much longer, and in the final measure is usually the better investment. (Some insurers even offer homeowners a discount on their premiums for metal roofs.)
Among the many advantages of a metal roof:
- The life expectancy is 50 to 75 years or even more, as opposed to the 15 to 25 years of life for an asphalt shingle roof.
- The surface reflects heat, lowering cooling costs in hot climates.
- They are less susceptible to leaking than shingles when installed correctly.
- They resist wind damage better than other roofing choices.
- Metal roofs are fireproof, making them good choices in areas where wildfire is a risk.
- Metal roofs are recyclable when they reach the end of their useful life.

While the two types of metal roof systems (standing seam and screw down panel) have their place in the industry, one is recommended for residential roofing.
A screw-down panel (also known as exposed fastener) metal roof is just what it’s called; it’s screwed down. The screws are screwed through the metal panels, which leaves no room for the metal to expand and contract as it goes through thermal expansion.
Because of this, you’ll pay to replace the screws every 5 years or so to prevent leaks or before a strong storm tears off the entire metal roof.
A standing seam metal roof system is a series of metal panels locked together at the seams or seamed mechanically. The metal panels are fastened under each of these ribs (standing seams), allowing them to glide back and forth when expanding and contracting.
You can get both types of metal roofs over your home.
But a screw down metal roof is better used over a carport, garage, back screened-in porch, barn, commercial properties, and anywhere that’s not a living or workspace because of the lack of expansion and contraction.
On the other hand, a standing seam metal roof is a great option for every situation and is strongly recommended for use over a heated living or workspace. Because of this, a standing seam metal roof is the recommended choice for residential roofing.
The 4 disadvantages of a standing seam metal roof
I can give you the disadvantages of both types of metal roofs. But because you’re here, you’re probably considering a metal roof for residential reasons.
That’s why we’ll only be covering the disadvantages of a standing seam metal roof for the rest of this article.
1. It’s harder to repair a standing seam metal roof
The first disadvantage is that a standing seam metal roof is harder to repair. While standing seam metal roofs are durable, things can still happen to the panels.
This could be rusting from damage to the painted finish, storm damage, or damage from not walking on the metal panels correctly. But when one of the above happens, it takes experience and more skill to repair a standing seam metal roof than an asphalt roof and some other roof types.
It will also be more expensive to repair due to the difficulty and the skill it needs to do the job right.
2. Oil canning is a possibility in a standing seam metal roof
The next disadvantage for a standing seam metal roof is that oil canning is a possibility.
Oil canning occurs when installers fasten the metal panels too tightly together. If this happens, it gives the metal panels room to expand longways but no room to expand sideways.
Over time your standing seam metal roof will show signs of oil canning that starts with a “bubbling” look that eventually turns into a wavy look on the metal panels.
Be aware; oil canning doesn’t cause any functionality problems.
But it does cause an aesthetic issue that some homeowners don’t like.
If curb appeal and aesthetics are a big deal to you, just know that oil canning is a possibility on a standing seam metal roof. To avoid this happening, hire a roofing contractor that has experience installing metal roofing.
3. The noise factor of a standing seam metal roof
The next disadvantage (and one of the most asked questions) is the noise factor of a standing seam metal roof. Just like oil canning, this isn’t a functionality problem with your metal roof.
No matter what, you will get an echo from the rain hitting your standing seam metal roof. But it’ll be quieter if it’s installed over solid decking because the wood (decking) between the metal panels and your ceiling helps absorb some of the noise.
You can also add wood fiber insulation boards between your roof’s decking and your metal panels to help with the noise. These boards will provide an extra layer to absorb sound, but they won’t completely block out a heavy downpour.
A standing seam metal roof will always make some noise when it rains. Even with what I mentioned above, it’s impossible to completely drown out the sound of rain when there’s a heavy thunderstorm.
4. A standing seam metal roof is expensive
The last disadvantage (and biggest concern to homeowners) is that a standing seam metal roof is expensive. Let’s compare the cost of the most commonly used asphalt shingle (architectural) roof to the cost of a standing seam metal roof as an example.
A two-story house with architectural (dimensional) asphalt shingles that has a little complexity, good accessibility will cost around $4.76 per square foot. You can expect a standing seam metal roof to be more than double and almost triple the cost at around $15.00 per square foot.
When most homeowners hear this, they avoid a metal roof and go with asphalt. But if you want a roof you won’t have to worry about for the next 50 years, a standing seam metal roof is great if you have the budget.
The guide that has all the advantages and disadvantages of different roofing materials
Now you know the disadvantages of a standing seam metal roof. Remember, you still can get a screw down metal panel roof over a heated living space, but I don’t recommend it.
After reading this article, you should have a good idea if a standing seam metal roof is an option for you.

Pros Of Metal Roofing
Metal Roofs Are Long-lasting and Durable
At the top of our list of benefits is the long lifespan of metal roofing. Many homeowners prefer metal roofing when replacing their roof or for new construction. It’s an investment that can keep the roof looking great and protecting your possessions for up to 70 years with the right maintenance. Plus, many manufacturers offer a 50-year warranty on a metal roof, while traditional roofing materials only have warranties of 20 years.
Because the material is highly durable, metal roofs can withstand the elements in your area. This includes wind gusts of 140 miles an hour. Since it has a rust-proof coating, it’s not going to crack or corrode.

Metal Roofs Are Environmentally Friendly
Traditional shingles are made of petroleum, so they are dependent on fossil fuels to produce.
They also must be replaced every 20 to 30 years, which means 20 billion pounds of shingles are sent to landfills every year.
Metal roofs are more sustainable because they use 25 percent or more recycled materials and are fully recyclable when they wear out their lifespan.

Metal Roofing Is More Energy-Efficient
Metal roofs have reflective properties, which means you can lower your heating/cooling costs throughout the year. Since it reflects solar heat and doesn’t absorb it, you can reduce energy costs in the summer by up to 25 percent.
With this benefit of metal roofing, it can help you save money in the long run while also keeping your home at a comfortable temperature.

Metal Roofs Are Stylish
Today, with the advancements in roofing materials, your metal roof doesn’t have to look like corrugated tin. You can choose from a variety of different materials.
These include galvanized steel, copper, zinc, tin, or aluminum.
On top of that, your metal roof can include many finishes, colors, and shapes. The variety here surpasses anything that could occur from traditional asphalt shingle roofing. Though asphalt can come in 20 colors, modern metal roofing offers hundreds of shades, including custom versions. Steel and aluminum are often used for residential metal roofing, and they can both hold finishes well.
Most homeowners with a metal roof use vertical ribbed panels called standing seam construction. However, such roofing isn’t short on options for style. If you like the traditional profile, you can choose options that look like clay tiles, slate, or wood. This can work well for you if you don’t like the standing seam look.
Your metal roof shouldn’t stand out or be an eyesore that detracts from your house. Instead, it can look like any other material. There are countless multi-layer factory finishes available to ensure a beautiful appearance and long-lasting lifespan.

Cons Of Metal Roofing
Metal Roofs Can Be Noisy
Some people do like the noise of rain as it hits a metal roof. However, this could be a con, depending on your preferences. If the rain on your metal roof is a concern, roofing experts can install more layers of insulation and sheathing to minimize what you hear in the house. This will, however, add that to the roof means higher costs.
-back to top
Metal Roofs Can Be Easily Dented
Your roof is the first defense for your home. Generally, a metal roof can be dented more easily than traditional asphalt shingles. That doesn’t mean it isn’t high-quality, but your metal roofing may need to be repaired or maintained more often. This extra work requires you to pay a professional to come onsite and do the job.
-back to top
Metal Roofing Is More Expensive
One issue with a metal roof is the cost.
Metal roofing materials can be much more expensive, and you need a roofing company that has experience installing a metal roof.
While the price is comparable to that of similar premium products, high-end metals can be 10 times the asphalt shingle price. Installation and labor can then be more expensive than other roofing materials and the equipment used to install it.
Of course, homeowners will be able to recoup their initial investment. You may need to pay for new shingles and roof repair more often than you will have to with metal. Just make sure you choose reputable metal roofing contractors to do the work on your home.

In this article I would like to talk about the most important issue of construction and repair of country houses. What roofing material to choose? When repairing or building a house, each owner must make a choice among a huge number of roofing materials, taking into account their preferences and financial capabilities.
New technologies and functional tricks appear all the time, so what should you choose?
House with a metal roof
If a person is not a specialist in the construction field, it will be quite difficult for him to decide. One thing can be said: almost any material will be suitable for covering a new building. Restrictions may be financial opportunities.
Let’s start with a few key factors to consider:
- Scope. If the building is not new and even dilapidated, then the strength of the roof structure and the walls themselves must be taken into account. Metal tile – a heavy type of roofing material – in this case is not suitable, as deformation of the building may occur.
- Type of construction: frame or capital.
- Weight. Light and heavy roofing.
- Type of roof: flat or pitched.
- Financial opportunities.
- Load resistance. Depends on climatic conditions.
- Service life.
- External view of the roof.
Metal roofing
Metal roofing
Metal roofing has been known to us since about the 10th century. Then a material made of lead was used, which was used to cover church domes. In the 14th century, domes began to be covered with copper, and sometimes even with gold. Everyone knows that this type of roofing was too expensive. Later, a special sign of wealth was a metal roof made of forged or tinned metal.
In the second half of the 19th century, sheet metal appeared and the price of metal roofing became more affordable. This led to the displacement of tinned and wrought iron. Galvanized iron came into fashion, which conquered the building materials market.
In Soviet times, iron roofing was used less frequently, as sheet slate took its place. And only after a long time, the iron roof again returns to the roofs of private houses and high-rise buildings.
Today’s galvanized roofing is very different from the roofing used in the last century.
It is much more durable, practical and most importantly – does not corrode. Such a roof can be used for ordinary and sloped roofs: garages, terraces, canopies, mansards, etc.
If you’ve decided to upgrade your roof and have opted for a metal roof, you must understand that the term “metal” is very general. The roof is made of zinc, copper, aluminium, stainless steel, etc.
Advantages of metal roofing
- It is reliable and durable.
- Easy to install, not a professional can work with it.
- Flame retardant.
- Attractive looking.
- Lightweight.
- In winter, snow will not accumulate on it due to the slippery surface.
- Service life is 3 times longer than that of shingles.
- Huge selection of metal and coating.
- Withstands extreme weather conditions: strong winds, hail, high temperatures.
- Protected against moss, mold, etc. Metal tile does not have to be cleaned.
- Unpretentious.
- In the hot season, the metal tile will keep the house cool.
- Made from recycled materials. Another plus for the environment.
- Recyclable.
- Has anti-corrosion properties.
- Is an environmentally friendly building material.
- You can choose any style of roof decoration: classic, modern, any individual design, etc.
Laying metal tiles
Disadvantages of metal roofing
But there are also disadvantages:
- Very noisy during precipitation (rain, hail).
- Due to certain chemical properties, the iron roof still oxidizes over time, therefore it must be treated with certain compositions or paint, sometimes completely changed. Regular preventive maintenance is required.
- Large losses of material are possible during the installation of complex structures.
Metal tile
Metal tile has a huge range of colors and is made of sheet steel. It is very similar to ordinary tiles, because each element is coated with a polymer coating, drawing and galvanized.
A big plus over other roofing materials is that the metal tile has a huge range of colors. You can choose the color that best matches the main elements of your building.
In general, at the moment, metal tiles are a fairly inexpensive roofing material.
With proper professional installation and periodic maintenance, an iron roof will serve you for a very long time.
What are the pros and cons of metal roofs?

Question from a reader of our portal: What are the pros and cons of metal roofs?
Answer: All metal roofs, whether it be metal tiles or corrugated board, are characterized by high durability, minimal maintenance, high strength and energy efficiency. However, it is important that the material of such a roof is chosen correctly, in accordance with the climatic conditions of your region.
For example, aluminum alloy metal roofs are commonly used in seaside homes, while stainless steel and tin roofs are commonly used in dry regions.
Let’s now look at some of the pros and cons of metal roofing.
Benefits of metal roofs
- High durability . The service life of a properly installed metal roof is about 40-70 years, depending on the materials used. For example, aluminum has the longest lifespan because it doesn’t corrode. For example, a traditional bitumen roof can last about 12-20 years;
- Environmental material . The metal roof is made from recycled materials. The amount of metal used in the creation of a metal roof is 25-95% of the recycled content. What’s more, they are also 100% recyclable at the end of their life;
- Effective insulation and UV protection . Metals are good conductors of heat. Metal roofing protects your home from ultraviolet radiation by properly insulating the roofing material, which is achieved by making a special coating. The covering material is used to reflect solar radiation and ultraviolet rays that can enter the house;
- Energy efficiency . Metal roofs are considered energy efficient as they reflect most of the solar radiation. This can be achieved by covering the surface of a metal roof with insulating material, which will save 20 to 30 percent of air conditioning costs;
- Lightweight . The weight of a metal roof is very small compared to classical and bituminous tiles, which allows you not to worry about the load on the building structure. The weight of a metal roof is about 1/4 of the weight of a shingle roof and about 1/2 of the weight of a shingle roof. In addition, the portability of such a roof helps to reduce the cost of installation, as it does not require a complex supporting structure;
- Maintenance free . A metal roof can last for many years with little or no maintenance. This is because it is a very hard material that does not break, flake or discolor over time;
- Safety . Although metals are good conductors of heat and electricity, they are practically non-flammable. The special coating applied to such roofs also prevents the risk of lightning strikes on the house. In addition, the non-combustible nature of the metal helps in slowing down fires. Class A metal roofs are very well suited for homes located in a high fire risk area, as they are considered fireproof;
- Appearance . A metal roof adds style to your home. Both popular metal tiles and corrugated board are now available in a variety of colors, styles and textures, allowing them to be matched to almost any home design. One of the best metal roofing is copper roofing because it changes color over time, adding extra beauty to your home.

Class A metal roofs are very well suited for homes located in a high fire risk area, as they are considered fireproof; Disadvantages of metal roofs
- Metal expansion and contraction . A metal roof expands and contracts as temperatures rise and fall. This expansion and contraction of the metal roof results in a shorter lifespan as the nails fly out. For this reason, most new products have fasteners that allow the metal to “breathe”;
- Color mismatch . Metal roofs discolour over time. So if you want to replace an existing metal roof with a new one, finding the exact replacement material can be tricky;
- Possibility of leakage . One of the disadvantages of a metal roof is considered to be the likelihood of leakage if improperly installed. Rainwater can seep through the screw holes if the special spring washers are not properly sealed around the screw heads. Therefore, before installing a metal roof, it is better to follow the manufacturer’s instructions;
- Noisiness . Metal roofs are quite noisy, especially during heavy rain or hail. The problem can be partially solved if heaters are laid under it, however, this greatly increases the cost of construction, despite the fact that there are no guarantees of silence;
- Potential for corrosion . Despite the fact that manufacturers apply various impregnations and anti-rust compounds to metal roofing sheets, the likelihood that the metal will begin to rust over time remains extremely high. Especially if the roofing sheets were incorrectly fixed or damaged by nails or tools during the laying process;
- Potential for salt attack . Such roofs should be carefully built near the sea. The metal is in very poor contact with salt water and the so-called salt fog. Therefore, if you are planning to build a house with a metal roof next to the sea, it is better to think carefully and analyze everything again. In general, the optimal distance from salt water, when the negative impact on the metal is minimal, is 500 meters or more.
For this reason, most new products have fasteners that allow the metal to “breathe”; 
Despite the fact that manufacturers apply various impregnations and anti-rust compounds to metal roofing sheets, the likelihood that the metal will begin to rust over time remains extremely high.

Metal roofing – the pros and cons
Everyone has seen a house with a metal roof at least once, and someone even plans to use it for their homes. The term “metal roofing” refers to roofing material made of copper, stainless steel, aluminum or other metal. Alloys can also be used. A very common option with the PM brand is a roofing material made of metal with a polymer coating. It protects the roof from corrosion and contributes to the preservation of color.
Metal roofing has many advantages
Metal roofing can also mean corrugated board used not only for roofs, but also for fences, fences and similar buildings, and metal tiles – an expensive and very beautiful analogue. There is a simple sheet iron, which is also used for roofing.
BUY METAL TILES
Benefits of metal roofing
strength and durability immediately come to mind metal.
Roofing with the choice of quality materials and proper installation will invariably last 3-4 decades. At the same time, the metal can hardly be called a material that is fragile or sensitive to external factors.
It is also worth noting environmental friendliness of metal roofing. It does not harm the environment or humans in any way, does not emit harmful substances and is easily recycled after use.
Obviously metal material non-combustible . Do not be afraid of a roof fire, although fire can damage the roof itself. And to strengthen the fire resistance of iron, you can use a special primer.
Do not think that a metal roof looks like an ordinary gray iron roof. This roofing material is available in various shades, both glossy and matte. Metal tiles, in addition to standard ones, can have any unusual color, if made to order. Therefore, wide color range will allow you to show your imagination and realize the desired design.
Metal roofing can be used not only for roofs, but also for shelters and gazebos
If one of the common shades is chosen, it will not be difficult to get accessories or consumables, for example, self-tapping screws or skates, of the desired color. This can be done immediately during the purchase of roofing material. The same applies to the drainage system.
Ease of installation is another indisputable plus of this roofing material. Modern sheets of profiled sheet or metal tiles are light enough, it is convenient to install them on the roof. And if the roof is changed, you can mount new sheets even on old beams without completely updating the roof.
Unusual metal roofing
Disadvantages of metal roofing
No one is perfect. Of course, metal roofing also has its drawbacks.
noise immediately comes to mind, which will torment the inhabitants of the house every time it rains or hail. Therefore, it is recommended to immediately think about sound insulation, and high-quality, so that later you do not have to either endure or sort out the roof.
Other disadvantage – slippery surface metal. In winter, snow will not linger on the roof, even if the slope is not too big. Without snow retainers, it will fall under the roof to the ground and accumulate there, because of which you will have to use a snow blower or a shovel more often.
The metal has rather high thermal conductivity . This means that in winter without good thermal insulation, the house will be cold. This increases construction costs.
If the roof is planned to be of an unusual shape, complex, it will take a lot due to trimming the metal. At the same time, you will have to figure out what to do with waste, which can be a lot. Financial costs including unused roofing – another disadvantage, but it only applies to complex roofs.
Metal roofing has several variations
What you need to know about seam roofing
Seam roofing is rolled or sheet metal used for roofing.
Under this option, a crate is needed, and they are fastened with the help of folds: another edge is inserted into the edge of the sheet bent in the form of a latch, which is bent upwards. To make the bond reliable, the edges are compressed with frames.
Seam roof sheets are also called paintings. If for some reason you are not satisfied with the standard sizes, you can always order the necessary parameters.
Pictures are made, as a rule, from galvanized steel, which is coated with a protective polymer. The thicker the zinc layer, the longer the roof will last. GOST defines the following types of seam roofing by zinc content:
- First class – 258 g/m2
- Second grade – 142 g/m2
- High content class – 570 g/m2
For residential buildings, it is best to take the first class.
There are varieties of other materials, for example, seam roofing is aluminum or copper. In the first case, it is a plastic and easy-to-install material, corrosion-resistant, durable, and of high quality.
But aluminum sheets are more expensive than steel sheets. Copper roofing will last even longer, it is stronger and therefore more expensive.
What you should know about metal roofing
Installation of metal tiles is carried out in a different way than in the case of seam roofing. They need to be laid overlapping and, as a rule, from right to left. Metal tiles are perfect for all kinds of figured roofs, except for round or semicircular options. It combines the aesthetics of ceramic tiles and the strength of metal. Thanks to the polymer coating that covers the sheets, the metal tile is protected from corrosion, does not lose its shade for years under the influence of sunlight and bad weather, and pleases the residents of the house with its attractive appearance.
Metal roofing is popular due to its functional and aesthetic qualities
What you should know about corrugated board
Corrugated board is also a metal roof. Its installation is quite simple, but differs from the installation of metal tiles or seam roofing.
After collecting the truss system, it is necessary to build a crate on which sheets of corrugated board will be laid.
It is important to remember that you need to align the sheets horizontally, or, as they say, along the cornice. They are mounted with an overlap of one wave. If the sheets are short, they can be overlapped longitudinally by at least 20-25 cm.
Metal roofing is an excellent solution for many applications. A variety of options, from rolled iron to metal tiles, allows you to adapt the roof to any home. In our online store you can purchase excellent materials for the construction of roofs and roof installation, arrange delivery and receive an order in the near future.

- Metal roofing material is lightweight, which saves on the construction of a supporting structure.
- This material is non-combustible with fire resistance class A. It makes them a refractory metal, although the resistance depends on the material underneath. If the material under the metal is wood, then it will heat up a lot.
- Helps keep the house cool in hot weather and helps melt snow in cold weather. This prevents ice damage to the roof.
- Most metal roofs will not crack or corrode, can withstand high winds and are impact resistant. They also don’t need frequent maintenance.
They also don’t need frequent maintenance. - This material can be recycled at the end of the life of the roof, making it more environmentally friendly.
Cons
- Due to the durability of the metal material, it is very expensive.
- If this roof is not properly installed or secured, rainwater can seep through the screw holes. Therefore, they must be well fixed on a flat surface and the screw heads sealed to avoid any leakage.
- They can be noisier, especially when it rains or hails. Noise can be controlled by using structural barrier materials to prevent any shocks.
- If large hailstones fall on the roof, this can cause dents in the metal. Metal roofs made of aluminum and copper are more susceptible to such damage than other types of materials.
- Warm or cold climates can cause the metal material to contract and expand, weakening fasteners. In hot weather, such fluctuations can lead to a wavy effect.
In hot weather, such fluctuations can lead to a wavy effect. - It is difficult to partially replace damaged roofing material, especially if it is installed on large panels. When reconstructing a house, it will be difficult to pick it up.
- Metal roofs are slippery, especially when wet, so be careful when walking on them.
- These roofs may fade over time.
- If it is not installed properly, it may fail at the seams, so it is best to look for an experienced contractor.

Various roofing systems are available on the market: shingles, metal roofing tiles which can be ordered https://proflistsochi.
ru/catalog/krovlya/metallocherepitsa/, wood, etc. Let’s discuss metal roofing here.
Metal roofing is a roofing system made of metal pieces or saw blades, characterized by high strength, impermeability and durability. This is a fast growing roofing system. However, it is important to study its pros and cons.
Advantages of a metal roof
Metal roofs are durable
First of all in our list of advantages is the long service life of a metal roof. Many homeowners prefer a metal roof for roof replacement or new construction. This is an investment that, with proper care, will help keep your roof looking great and protect your property for up to 70 years. In addition, many manufacturers offer a 50-year metal roof warranty, while traditional roofing materials only have a 20-year warranty.
Because the material is very durable, metal roofs can withstand the elements in your area. This includes wind gusts of 200 km. in hour. Since it has an anti-corrosion coating, it will not crack or corrode.
Eco-friendly metal roofs
Traditional roof tiles are made from petroleum and are therefore dependent on fossil fuels. They also need to be replaced every 20–30 years, which means 10 billion kg. shingles are sent to landfills every year.
Metal roofs are more sustainable because they use 25 percent or more recycled materials and are fully recyclable when they wear out.
Metal roofing is more energy efficient
Metal roofing is reflective, which means you can reduce your heating/cooling costs throughout the year. Because it reflects the heat of the sun and doesn’t absorb it, you can cut your energy costs in the summer by up to 25 percent.
With this benefit of metal roofing, it can help you save money in the long run and keep your home at a comfortable temperature.

You can choose from many different materials. These include galvanized steel, copper, zinc, tin or aluminium.
In addition, your metal roof can come in many finishes, colors and shapes. The variety here surpasses anything that could come from traditional shingle roofing. Although asphalt comes in 20 colors, modern metal roofing offers hundreds of shades, including custom ones. Steel and aluminum are often used for residential metal roofing and both hold the finish well.
Most metal roof homeowners use vertical ribbed panels called standing seam construction. However, there are many style options for such a roof. If you like the traditional profile, you can choose options that look like clay tiles, slate, or wood. This might suit you if you don’t like the look of a standing seam.
Your metal roof should not stand out or irritate the eye, drawing attention away from your home. Instead, it can look like any other material. Countless multi-layer factory coatings are available for beautiful looks and long life.
Metal roofing cons
Metal roofs can be noisy
Some people like the sound of rain when it hits a metal roof. However, this can be a disadvantage, depending on your preferences. If rain on a metal roof is a concern, roofing professionals can install more layers of insulation and sheathing to minimize what you hear in the home. This, however, will add that roofing means higher costs.
Metal roofs dent easily
Your roof is your home’s first defense. As a rule, dents appear more easily on a metal roof than on traditional shingles. This does not mean that it is of poor quality, but your metal roof may need more frequent repairs or maintenance. This extra work requires you to pay a professional to come to the site and do the work.
Metal roofing more expensive
One problem with a metal roof is the cost. metal roofing materials can be much more expensive and you need a roofing company that has experience installing metal roofing.
Although the price is comparable to similar premium products, expensive metals can be 10 times more expensive than asphalt shingles. In this case, installation and labor can be more expensive than other roofing materials and equipment used to install them.
Of course, homeowners will be able to recoup their initial investment. You may have to pay for new shingles and roof repairs more often than you would for metal. Just make sure you choose reliable metal roofing contractors to do the work on your home.+*-
Conclusion
Metal roofing is overwhelmingly becoming the choice of many homeowners because of what it has to offer; longevity, attractiveness and much more. However, it is recommended that whatever material or system you choose for your roof, it is always important to make sure it comes with a warranty and also make sure it is installed by an experienced contractor so that your investment is not wasted.
Metal tile. Pros and cons of roofing from metal tiles
Most modern buildings are equipped with a roof that is made of a material that is unique in its properties – metal tiles.
But not everyone knows where such a roof first appeared, and why it is so in demand today. The invention of such a building material is the work of one specialist who lives and works in a small town in Finland, Vimpel. This event dates back to the mid-60s of the 20th century. Many consider Paavo Rannila to be the creator of modern roof tiles, and this is true. In the near future, after the release of his first products, he opened a Finnish company for the production of the most popular type of roofing material today, and the production was called RANNILA STEEL Oy. The company’s specialists developed and produced Monterrey metal tiles, they also had copyrights to it and supplied their products to other countries.
According to its author, the idea of creating tiles from profiled steel sheet appeared spontaneously. Once this person simply drew attention to private houses, of which there were a lot in Finland and Scandinavia, and they all had a reliable, but unaesthetic metal roof made of a trapezoidal sheet.
The question arose: why not add an attractive appearance to such qualities of a roofing material as practicality and resistance to external factors? To implement the plan, a metal sheet was taken. And with the help of special equipment, its surface along the length acquired the form of an asymmetric wave. A cross stamp has also been added. In appearance, the metal tile was in no way inferior to the natural clay analogues of the tile, and in terms of performance it was much superior to them. Today, the roofing material invented by Paavo Rannila has 9layers. This significantly increases the service life of metal tiles. It includes: 2 primer coats, 2 passivation coats, 2 galvanized coats, sheet steel, front and back side paint. Of course, all layers are placed in a certain sequence.
The main advantages of metal tiles
1. Profitability when creating a roof of any scale.
Metal tile is considered an inexpensive roofing material, and if we take into account the duration of its operation (within 50 years), then investing in the roof of your home or any other building will be required only once.
Now a person will be able to significantly save on the operation of roofing material, because it does not require any additional care and repair work.
2. Relative lightness of the material.
Due to the fact that 1 sq. m of such tiles on average weighs no more than 6 kg, this not only facilitates the process of its installation and transportation, but also does not create additional loads on the building itself, especially if it has a poor quality foundation. The minimum load on the walls of the construction site and the elements of the truss-mauerlat group also indicates that with the help of metal tiles it is possible to create a roof of absolutely any area. Productivity of laying of a tile is rather high, and labor costs are minimum. Therefore, there is no need to use auxiliary materials for lathing, reinforced rafters, etc.
3. Resistance to external influences.
Gepard’s Nikolaev metal tile, due to its unique structure, can be used in absolutely any climatic zones and under any weather conditions.
Water and snow will not accumulate on the surface of the tiles, and exposure to ultraviolet rays will not cause the loss of the original qualities of the roof. Another important plus is resistance to various mechanical influences. And even if some part of the roof is damaged, it can be easily replaced with a new one.
4. Aesthetics of the roof.
Unlike other materials, it is characterized by high rates in terms of its aesthetics, because the wide range of design options allow you to create not just a reliable protection of the building from external influences, but a real work of art. The desired color solution is chosen due to the rich color gamut, while the pattern can also be very different. Roofing of various configurations is not a curiosity today.
As you can see, very impressive positive qualities are inherent in metal tiles, which is why it is in great demand among other roofing materials. Many also pay special attention to such indicators as the environmental friendliness of the material and its fire safety, and tiles made from metal sheets are 100% compliant with these requirements.
But at the same time, when choosing a metal tile in Vinnitsa, it is important to pay attention to its shortcomings, of which there are only two.
Disadvantages of metal tiles
1. Loss of material when working with complex roofs.
If you plan to cover the roof of a building, which is distinguished by its complex structure, with metal tiles, then you need to prepare for the fact that during cutting out there will be a lot of residues. Experts do not recommend the use of such tiles in relation to those roofs where there is a significant number of valleys and ridges. The best option is roofs of a simple configuration and without the presence of curved surfaces.
2. Increased noise level during rain.
Quite often, residents of houses with a roof made of metal tiles complain about the increased noise level on days when it rains or hails. Some attribute this disadvantage to the relative lightness of the material, while others point to errors made during installation.
