Metal roofing is one of the few fire-resistant roofing materials available. Fire resistance is a top-of-mind issue for those who live in wildfire-prone areas. Wind-blown embers from wildfires can set fire to their homes, most often landing on their roof. The number one investment you can make for your dwelling is to protect the roof from fire.
Other Fire-Resistant Roofing Materials
House fires ignite neighboring homes due to wind-blown embers. They have destroyed entire neighborhoods where the predominant roofing material was wood shakes. Asphalt shingles and wood shakes are usually treated to be fire-resistant, but as these roofs dry out and age, they become more and more vulnerable. It only takes one ember from a nearby wildfire, house fire or even a tree struck by lightning, to ignite the roof.
Metal Over Slate
Metal, slate and tile are the only 100% non-combustible residential roofing materials. With metal weighing only 40 – 90 lbs. per square, versus slate and tile weighing 1000 – 1400 lbs. per square, it is the only fire-resistant option for most homeowners. Firefighters have instructions not to enter homes with tile roofs. As the home’s structure gets compromised, the weight of the roof becomes too much to bear, and the roof collapses.
Fire Resistance Classifications for Roofs
Fire classification of roof assemblies is generally based on ASTM E108 and UL 790. Each requires a spread of flame tests and a burning brand tests. Tested roof systems are fire classified Class A, B, or C, where A is the most fire-resistant roof and C is the least fire-resistant.
