Roof Moss Removal Service Using Scraper Tool on Asphalt Shingles for Home Maintenance and Exterior Cleaning Project

Moss and algae growth on Seattle roofs isn’t just unsightly, it actively damages shingles, retains moisture, and accelerates roof aging. Left untreated, moss can cut your roof’s lifespan by years. Our treatment safely eliminates growth and applies preventative solutions.

  • Hand-Tool Moss Removal
    Our technicians manually remove moss using professional hand tools, carefully working across your roof surface without applying any water pressure. This gentle, hands-on approach protects your shingles, preserves roof coatings, and ensures thorough removal that pressure washing simply can’t match, especially in the thick moss conditions common across the Pacific Northwest.

  • Algae & Lichen Treatment
    Targeted biocides eliminate black streaks, green algae, and stubborn lichen growth.

  • Preventative Zinc Treatment
    Zinc-based solution applied after cleaning to inhibit future moss regrowth for 1–2 years.
