Question: 1 / 400

What is the primary material in composite shingles?

Fiberglass

The primary material in composite shingles is fiberglass. These shingles are designed with a fiberglass mat base that provides structural integrity and reduces the overall weight of the roofing product. Fiberglass is used because it offers considerable strength and durability while resisting moisture and fire, which are critical attributes for roofing materials.

In composite shingles, the fiberglass mat is typically coated with asphalt and granules that provide protection against UV rays and further enhance durability. This composition allows composite shingles to offer a good balance of performance, lifespan, and aesthetic appeal.

Other materials such as vinyl, wood, and metal do not serve as the main components of composite shingles, which is why they do not fulfill the requirements to be considered primary materials in this context. Each of those materials has its own roofing applications but does not reflect the structure and benefits of composite shingles.
