What advantage do glass fibers provide in shingles?

1. Increased insulation

2. Lower cost

3. Enhanced durability

4. Increased weight

The correct answer is: Enhanced durability

Glass fibers used in shingles provide enhanced durability primarily because they contribute significantly to the strength and stability of the asphalt roofing material. By reinforcing the asphalt, glass fibers help the shingles resist cracking, splitting, and other forms of wear and tear that can occur over time due to exposure to environmental elements such as wind, rain, and UV radiation. The inclusion of glass fibers also allows for better dimensional stability compared to organic materials, which can be more prone to deterioration. This durability translates into a longer lifespan for the shingles, thus making them a more reliable component of the roofing system. Therefore, selecting shingles with glass fibers is often recommended for homeowners and builders seeking a long-lasting roofing solution.
