Which type of asphalt shingles are made with a fiber glass mat?

• A. Felt
• B. Fiber Glass Shingles
• C. Eaves flashing
• D. Exposure

Answer: (B)

Reinforcement material is what distinguishes different asphalt shingles. Fiberglass shingles are made with a fiber glass mat as the reinforcement, which is embedded in asphalt. This fiberglass mat provides strength, good tear resistance, and better fire performance while allowing the shingle to be thinner and lighter.

Felt-based shingles use a felt (organic, usually cellulose) base instead of fiberglass, so they’re not the fiberglass-reinforced kind. Eaves flashing isn’t a shingle type at all but a metal detail used at the roof edge. Exposure is a term that describes how much of a shingle is visible once installed, not what it’s made from. So the option that describes fiberglass reinforcement is the correct one.
