Roof Cleaning in Seattle, at the root

Seattle's near-constant damp makes moss on the north roof slope almost universal — we take Seattle roofs, with a focus on north-end neighborhoods.

Why Seattle

What to know about roof cleaning in Seattle

In Ballard, Wallingford, Green Lake, Wedgwood and Phinney Ridge, 1920s–40s Craftsman and Tudor homes have steep roofs that grow moss on every shaded face. Tight city lots and street parking make setup more involved, so we plan access before we arrive. Because Seattle is at the edge of our range, we prioritize north-end addresses and roofs of a decent size, and we say plainly if a job doesn't pencil out.

Timing

When to schedule roof cleaning in Seattle

Seattle roofs commonly want attention every two to three years given the damp. Spring through early fall is best. Send your address and a photo or two and we'll tell you honestly about scheduling. If the walkways and steps have grown green too, ask us to bundle <a href='/services/pressure-washing/'>pressure washing</a> into the same visit.
