Roofing materials are rated as Class A, B, or C based on their fire resistance.

Class A is the most fire-resistant, and Class C is the least.

Class A;

-The highest level of fire resistance

-Can withstand severe fire exposure

-Recommended for homes in wildfire-prone areas

-Examples include asphalt shingles, concrete or clay tiles, slate, steel, or copper roofs

 

Class B;

-Effective against moderate fire exposure

-Less effective than Class A but still provides reasonable fire resistance

-Examples include fire-retardant pressure-treated shakes and shingles

 

Class C;

-The lowest level of fire protection

-Only basic defense against light exposure to fire

-Examples include untreated wood shakes and shingles, plywood, particleboard, rubber, and plastic roof products
