What is the primary material used in organic asphalt shingles?

The primary material used in organic asphalt shingles is cellulose-fiber base. Organic asphalt shingles are manufactured using a base made from materials such as recycled paper or wood fibers. This cellulose base provides flexibility and strength, making the shingles more durable and effective in resisting damage from environmental conditions.

In contrast, fiberglass mat is the main component of fiberglass asphalt shingles, which are a different type of shingle. While cedar wood and clay or concrete are used in other types of roofing materials—namely wooden shingles and tile roofs, respectively—they are not associated with organic asphalt shingles. Understanding the composition of different roofing materials is essential in the roofing industry, especially when distinguishing between types of asphalt shingles.
