Roof Cleaning in Washington State

The mistake most Washington homeowners make is reaching for a pressure washer. High-pressure washing removes visible growth but blasts away the protective granules at the same time, shortening the remaining life of the roof by years and potentially voiding manufacturer warranties. Our soft wash process applies a biodegradable cleaning solution at low pressure that kills moss, lichen, and algae at the root. The organisms die in place and rinse away in subsequent rain. No granule loss. No shingle lifting. No water forced under overlapping courses. The 2-year guarantee on our roof cleaning services is backed by this approach because we do not offer a guarantee on work that damages the surface we are cleaning.

Washington roofs face a secondary problem as well: when heavy moss clumps break free during winter storms, they wash directly into gutters and downspouts, creating blockages that cause overflow against foundation walls. If your gutters are overflowing during wet season, significant moss coverage on the roof is often the upstream cause. Professional cleaning of both the roof and gutters addresses the full drainage system before the next Pacific Northwest winter.
