Which class of asphalt shingles would have the best fire rating?

Explanation:
Fire ratings for asphalt shingles show how well a roof resists ignition and flame spread, with higher ratings indicating stronger fire performance. Among the common scales, Class A provides the most resistance and is designed to withstand severe fire exposure, offering the best protection. That’s why the top-rated option is the one labeled Class A. Class B and Class C indicate progressively less fire resistance, and Grade A isn’t a standard, widely used roofing-fire rating.
