Which type of roofing is primarily reinforced with organic felts or fiberglass?

Asphalt shingles are primarily reinforced with organic felts or fiberglass, which serves as the base material providing structural integrity and durability to the shingles. Organic felts typically consist of cellulose fibers that have been saturated with asphalt, while fiberglass shingles use a fiberglass mat, offering improved strength, lighter weight, and resistance to fire. Both types serve as a substrate for the asphalt coating that provides water resistance and protection from the elements.

This makes asphalt shingles a popular choice for residential roofing due to their balance of durability, cost-effectiveness, and ease of installation. The presence of these reinforcing materials plays a critical role in enhancing the overall performance and lifecycle of the roofing system.
