Is Asphalt Roofing Fire Resistant?
Is asphalt roofing fire-resistant? For most, yes. Most asphalt roof shingles are class A fire rated.
What is a Class A Fire Rating?
Class A fire-rated indicates a flame spread rating between zero and 25. Additionally, the materials do not burn well, generate smoke, and are not likely to contribute fuel to a fire. Class A is the highest fire rating that a material can receive. Examples of materials that are class A fire-rated are gypsum board, fiber cement siding, brick, concrete, and steel.
How are Asphalt Shingles Class A Rated?
Asphalt shingles are class a rated because they will resist combustion in a house fire for a long time. The fiberglass matting in shingles contributes much to the fire-resistant qualities. While it is true that asphalt shingles are partially made from petroleum, a highly flammable material, the additional components, like the fiberglass mat, increase its ability to resist fire.
Using synthetic underlayment increases fire resistance over the felt paper, which is flammable. If a fire-resistant roof is a priority for you, then ensure the underlayment installed on your roof has been fire tested and the best material to use.
Other Fire-Resistant Roof Coverings
Other great Class A roof coverings are materials like concrete and clay tiles and metal roofing. All of these materials are naturally fire-resistant and, as a bonus, also Class IV roof coverings, which means that they are impact-resistant and qualify your home for a discount on insurance.
How to Choose a Roof Covering for Your Home?
When it comes to choosing a new roof for your home, you have many options. Asphalt shingles have multiple variations, like laminated, luxury, and Class IV shingles. Metal roofing is another great option for most homes. Metal roofing can be your classic, beautiful standing seam roofs or durable stone-coated steel, which comes in several profiles to look like tile roofing, shingles, and wood shake.
