Composite Roof Life Expectancy

Compared to asphalt roofing, composite shingles are made to stand the test of time. This type of roofing typically lasts 20 years. However, with the right materials and proper maintenance, composite shingles can last up to 50 years and beyond. Accordingly, many composite roofs carry a warranty of 20 to 50 years, but the warranty length will ultimately depend on the manufacturer.

Why Does Composite Roofing Last So Long?

There are many factors that contribute to the longevity of composite roofing. First and foremost, composite shingles are made from a blend of materials – typically a combination of fiberglass, plastic, polyester and paper bonded by resin or laminates. When mixed together, these materials create a recipe for strength and durability.

Thanks to their composition, these types of shingles won’t crack, split, peel or warp. They also offer a high level of fire resistance and impact resistance, helping prevent damage from hail and other hazards. What’s more, composite shingles resist fading caused by sun exposure, allowing them to maintain their pristine look for time to come.
