What's different about roof cleaning and repair in Seattle

Seattle’s wet-season drainage needs make roof and gutter upkeep especially relevant, with Sea-Tac’s 1991–2020 normal annual precipitation at 37.49 inches and a normal January average high of 48.0°F. In Ballard, Fremont, and Green Lake, assess moss buildup, roof material, pitch, height, access, runoff control, and fall protection before cleaning. Soft washing, moss removal, prevention treatment, and gutter cleaning each need a scope that protects roof surfaces while addressing drainage.

Seattle’s housing includes a 1939-or-earlier cohort in the 2024 ACS year-built table, so older roofs may need a close repair assessment alongside cleaning. Seattle lists permits for additions, alterations, and re-roofing, making permit review important when repair work reaches those project types. For repairs, use an insured roofing contractor licensed where required and confirm active Washington L&I registration, bond, insurance, and complaint history. Cleaning-only work is generally unlicensed.
