Top-Rated Roof Moss Removal & Cleaning in Seattle, WA

Call (206) 822-2320

If your roof in Seattle has dark streaks or moss creeping across the shingles, that's not just dirt — it's algae and moss slowly eating into the shingles underneath. I clear it with a soft brush and a moss-killing powder treatment, never high pressure, so your roof stays protected instead of stripped.
