Roof Cleaning

Asphalt shingle roofs that are in constant shade tend to attract algae growth, which feeds off of microscopic particles in the limestone used in the shingles. This growth can be seen as a black or dark green staining on the roof and many homeowners are eager to get rid of it.

Roof cleaning isn’t harmful if done professionally, and many homeowners value the aesthetics of a clean roof. However, some people believe it does not add to the longevity of a roof. The argument for roof cleaning states that it improves the curb appeal of a home, and protects the shingles, which ultimately extends the life of a roof. It’s also believed to improve energy efficiency because a darker roof will generate more heat.
