Most roofing materials are fire-resistant. We must emphasize that being fire-resistant does NOT equate to being fire-proof. Roofs can and do catch fire. We’ll explain the meaning of fire-resistant roofing and how it protects homes.
Fiberglass is the most common shingle type for residential roofs. Fiberglass, as well as some cedar shingles, have a class-A in fire rating. This does not mean the shingle does not catch fire. A class-A rating means the material will hold together under the flame. The shingle will not blow off and create flying embers that could cause the fire to spread. Also, it will not crack under the heat or create an opening that can expose the attic interior to the flames.
Keep in mind that homeowners still need to do their part to prevent fires from spreading. This includes removing tree branches that rest near the roof and might catch fire.
Roofs can also catch fire during construction. This is especially true of commercial roofs. Just do a Google search of a term like “fires started by roofers.” You’ll find stories of roofers causing a fire with their torches or even from smoking while on the job.
One incident involved a devastating roof fire at a Chicago strip mall. Another involved a blaze at a construction site in Arizona. Such instances are the result of uncertified roofers who did not follow protocol while installing a torch-down roof. Incorrect methods can cause materials in the attic or insulation to overheat and erupt in flames. This is especially a common mishap in the warm summer months.
