Asphalt Shingles Class A asphalt shingles can withstand a fire burning through the wooden structural components for up to two hours. Because asphalt shingles are relatively inexpensive, they are the most common roofing material, especially in areas where fire isn’t an ever-present danger.
For areas prone to wildfires, asphalt shingles are generally considered a fire-resistant roof covering. Roof coverings have fire classifications of Class A, Class B, or Class C, or are unclassified. Class A have the highest resistance to fire and unclassified have the least.
Another frequently asked inquiry is “Is asphalt flammable?”.
Asphalt is flammable if overheated when oxygen is present. Some asphalt cements and air-blown asphalts are not combustible until heated above 450 °F (232 °C). The ability of asphalt to catch fire varies with the type and amount of solvent.
Then, are class A shingles flammable?
Class C Fire Rating – Shingles that offer light fire resistance are classified as Class C. These shingles aren’t readily flammable, won’t readily spread fire and are effective against lighter fire exposures. Obviously Class A shingles are your best bet as they provide the strongest protection against fire.
