Fiberglass shingles FAQs

How long does an asphalt fiberglass roof last?

An asphalt fiberglass shingle roof lasts 15 to 30 years with proper maintenance, depending on the shingle style, climate, and amount of direct sun exposure. Fiberglass shingles have a lower life expectancy in areas with freezing climates, excessive heat, or extreme temperature changes.

Roof cleaning costs $250 to $600. Have the roof cleaned every 1 to 3 years to extend its lifespan.

What are fiberglass roof shingles made of?

Fiberglass roof shingles feature a woven fiberglass base mat sealed with a waterproof asphalt coating and topped with ceramic granules to add color, texture, and UV protection.

Do asphalt shingles contain fiberglass? {#fiberglass)

Fiberglass shingles have a fiberglass base mat coated with asphalt, but they contain 40% to 50% less asphalt than older organic asphalt shingles. Manufacturers stopped producing organic asphalt shingles in 2008, and all asphalt shingles manufactured today use fiberglass.

Can you walk on a fiberglass shingle roof?

Yes, you can walk on a fiberglass roof if the roof decking is stable. Avoid walking on the roof unless necessary as it may dislodge the granules on the shingles and cause the roof to deteriorate more quickly.
