Metal Roofing 101: Understanding Fire Resistance

Fire resistance is one of the main reasons why more and more homeowners are investing in metal roofs. The ability not to ignite when struck by lightning or when exposed to embers is such a desirable quality to have in a roof.

To be clear, metal is not the only noncombustible roofing material on the market. In fact, most products these days are at least resistant to fire to some extent. Yet, metal is the favorite of firefighters and insurance companies. Here’s why.

What Makes Metal Roofs Fire-Safe?

It is not an accident that the roof assemblies classified as Class A chiefly consist of metal components. As mentioned, the material is 100% noncombustible. Slate and tile are the only other roofing options that can claim this distinction.

Every roofing company worth its salt will agree that weight sets metal apart from other noncombustible materials. It is incredibly strong, but also amazingly light. Even when paired with combustible components, metal panels are unlikely to cause an entire roof to fall under its own weight.

Although their coverings do not burn, structurally compromised slate, concrete and clay roofs might collapse. Protocol dictates that firefighters should not enter a burning house with a tile roof.

How Do They Compare to Fire-Resistant Asphalt Shingles?

Many high-quality asphalt shingles like GAF products can meet the industry’s highest roofing fire rating. However, asphalt shingles may not be able to retain their enhanced fire resistance throughout their service lives. The more they age, the more they become susceptible to combustion.

On the other hand, metal panels are immune to fire forever. That is why they hardly require any major roof repair service for decades.
