For most roofs in Olympia, we recommend professional roof cleaning every 1-3 years depending on your roof type and moss growth patterns. Cedar shingle roofs in our wet Pacific Northwest climate may need annual cleaning and moss treatment, while asphalt shingles typically require cleaning every 2-3 years. Factors like surrounding trees, roof pitch, and exposure to moisture affect cleaning frequency. Our Olympia roof cleaning specialists can assess your specific roof and recommend the ideal maintenance schedule to prevent moss damage and extend your roof's lifespan.

It's probable that the dark stains visible on your roof are caused by Gloeocapsa Magma, a type of algae that thrives in humid weather. This particular algae feeds on the limestone filler used in asphalt shingle production, causing discoloration, staining, and damage to the shingles. Neglecting this problem can reduce your roof's lifespan and detract from your home's curb appeal. To prevent algae growth and maintain your roof's integrity, it's crucial to clean it regularly.
