Asphalt Roofing Shingles
Referring to asphalt roofing as “shingles,” however, is somewhat misleading.

Fiberglass, or inorganic, asphalt shingles have a base mat of synthetic fiberglass, also given an asphalt and ground mineral coat. Because both types of shingle receive the asphalt treatment, they are lumped together as asphalt shingles. The biggest advantage inorganic asphalt singles have over organic ones is that their fiberglass base mats increase their fire resistance ratings.
