Roof Cleaning in Portland, OR
Portland's wet, shaded climate is exactly what moss, algae, and lichen love — and exactly why we built Moss Boss. We're a locally owned roof cleaning company serving every Portland neighborhood, from Sellwood and Hawthorne to St. Johns, the West Hills, and outer SE.
Why Portland homeowners choose Moss Boss
Portland homes get hit harder by roof moss than almost anywhere in the country. Towering Doug firs, north-facing slopes, long wet winters, and decades of shade-grown algae mean almost every roof here needs attention every 2–3 years.
We've cleaned roofs across every Portland zip code — craftsman bungalows in Sellwood, mid-century ranches in NE, modern infill in St. Johns, and steep cedar-shake homes in the West Hills. Each roof gets a soft wash treatment that kills moss at the root, plus our 3-year moss-free warranty so it actually stays clean.
Most Portland quotes get a slot within 5–7 days during peak season.
Based in Portland — we don't tack on travel fees for any city neighborhood.
West Hills and Mt. Tabor homes are our specialty — we have the gear for steep pitches.

"Our Sellwood roof had moss so thick you couldn't see the shingles. Moss Boss soft washed it, treated it, cleaned the gutters, and threw in the skylights — all in one morning. Two years later it still looks great."
