FAQs

While the upfront costs of installing a metal roof are often higher than shingles, a metal roof lasts longer and will be replaced or repaired far less frequently. A typical shingle roof lasts anywhere from 12 to 20 years, depending upon how well it’s maintained and weather elements it may encounter. Metal roofs, on the other hand, can last between 40 and 60 years while also requiring less maintenance, making them a more cost-effective choice over the lifespan of the roof.

While it may be true that metal roofs on buildings like garages and pole barns intensify the sound of falling rain, this is primarily caused by the lack of a roof deck, insulation, and underlayment. On a residential home, layers of building materials between the metal roof and the living area reduce the noise significantly, making metal roofs as quiet as any other roofing material when it rains. Check out this video to see and hear for yourself.

Metal roofing actually reflects much of the sun’s heat and energy. While conventional shingles absorb much of the sun’s heat, metal roofing can actually reduce cooling energy costs by as much as 20%. That’s because the coating used on modern metal roof panels incorporates special pigments that reflect the sun’s energy and release heat that is absorbed throughout the day.

Residential metal roofing is available in a variety of aesthetically pleasing designs that can heighten the curb appeal of any home. In addition to conventional panels, there are several styles that are virtually indistinguishable from conventional tile and shingles. Metal roofing is available in a wide array of colors as well, making it easy to find an option that best suits any style of residential home.

The odds of a lightning strike hitting a metal roof are the same as any other roof, regardless of material. In the event that there is a lightning strike, however, metal roofing will not ignite and catch fire since it is not combustible.

Far from it. Studies conducted by the Insurance Institute for Business & Home Safety (IBHS) have found that metal roofing is far less likely to be punctured by hail than conventional asphalt shingles, withstanding even golf ball-sized hailstones with only cosmetic damage.

Metal roofing consistently outperforms shingles when it comes to resisting harsh elements. In addition to being fire and hail resistant, metal roofs are also effective against extreme winds. Many insurance companies recognize the durability of metal roofing, offering discounts for structures with metal roofs.

Definitely not! Like most building materials, metal roofing is available in varying levels of quality. Homeowners should be sure to ask their contractor or supplier what substrate and paint coating they are recommending for their home. Galvalume steel substrates and Kynar 500® (PVDF) coatings provide the best long-term peformance. Click here for facts about substrates and coatings.
