Metal Roof FAQ

Although common in most areas of the United States, metal roofs are not as widespread as asphalt shingle roofs in New England. Many customers come to us with questions about the performance and durability of a metal roof. Here are some of the most frequently asked questions we hear at Performance Roofing.

Is a metal roof noisy?
No. Sound deadening makes noise transference in a metal roof about the same as a shingle roof.

Won’t a metal roof make my house too hot?
No, a metal roof can actually keep your home cooler. Metal roofs reflect solar light, where shingles absorb the energy from sunlight. The painted metal has an ENERGY STAR® rating which means it can help reduce your energy bill.

Does hail damage a metal roof?
Metal roofs are highly resistant to hail damage, much more so than shingle roofs. A metal roof has tensile strength that is nearly three times stronger than the metal used on your car or truck!

Do metal roofs rust?
No. Advances in coating technology have created silicone polyester paints with galvanized substrate that protects the metal panels.

Can a metal roof be repaired if it is damaged?

Although metal roofing systems are incredibly durable, they are also easy to repair if any damage occurs. The metal panels can easily be replaced.

Does the color fade in the sun?
Overtime you might see a slight change in color due to the setting of airborne contamination. Washing the roof occasionally with water will keep the roof looking new.

Does a metal roof attract lightning?
No, a metal roof has no greater chance of lightning hitting it than any other type or roofing material.

Is a metal roof fire safe?
Yes, a metal roof is the most fire resistant roof available.

Is a metal roof resistant to wind damage?
Wind warranties can be as high a 140 MPH on many styles of metal roofing.

Does it damage a metal roof to walk on it?
No, metal roofs are strong enough to support most people. But, as with any roof, you should always use caution when walking on a metal roof.

Can a metal roof be put over an existing roof?
Yes, if the underlying structure is strong enough.

How do you compare the weight of a metal roof to other types of roofing?
Metal roofs are actually much lighter than other types of roofs.

Is a metal roof cost effective compared to other types of roofs?
Metal roofs cost more than a shingle roof, but metal roofs last longer – often 50 to 100 years – and offer other benefits.
