Materials Used to Make Asphalt Shingles
These roofing shingles are mainly made of fiberglass or organic materials.
Fiberglass asphalt shingles comprise of a mat base that is covered and saturated with flexible asphalt. They are also surfaced with mineral granules. Fiberglass shingles were introduced in the 1950s.

The base mat provides strength for the shingles. It’s covered with a saturant (flexible asphalt with a high melting point).
The saturant is reinforced suing trap rock, ground limestone, slate, and similar inert materials. Additionally, coarse mineral granules are pressed on the surface of the asphalt to give it color. This makes the shingles fire and weather resistant. The backside of the shingles is covered with mica, talc, or sand to prevent them from sticking together.
