If your roof has gone green, moss and algae are already working under the shingles. We remove it the safe way — low pressure, no shingle damage — so your roof lasts longer and your home looks clean again.
Spokane
Rooftop moss capital
Spokane gets long, wet winters and plenty of shade from mature trees. Moss and algae love those conditions, and they spread fast across asphalt shingles. When moss takes hold, its roots work their way under the shingle edges and lift them up.
Once the shingles lift, water gets underneath. That leads to rot, leaks, and a roof that fails years before it should. Removing moss isn't just about looks — it's about protecting the biggest investment most Spokane homeowners have.
Yes — when it's done with soft washing. Soft washing is a low-pressure cleaning method that uses specialized, biodegradable solutions to kill moss, algae, and mildew at the root. The solution does the work instead of brute force, so nothing rips or lifts your shingles.
High-pressure washing is a different story. Blasting a roof with a pressure washer strips the protective granules off asphalt shingles and can void your roofing warranty. That's why we never pressure wash roofs — and why you shouldn't let anyone else do it either.
Pressure washing a roof can damage shingles and void your warranty. We don't do it. Ever.
Warranty
Safe cleaning method
No ladders-and-scrubbers guesswork. Just a tested, four-step process tuned for Spokane roofs.
We inspect your roof, identify the moss and algae, and give you a clear quote.
We protect landscaping and gutters, then apply a biodegradable cleaning solution.
We rinse at low pressure and manually remove heavy moss without harming shingles.
The solution keeps working after we leave, killing remaining moss so it doesn't come right back.
We don't quote roof cleaning with a one-size-fits-all number, because no two roofs are the same. The price depends on what your roof actually needs — its size and square footage, the pitch and how many stories up it sits, how much moss and algae has built up, the roofing material, and how easy the roof is to access.
Tell us about your roof, send a couple of photos, and we'll give you a straight, no-pressure quote within 24 hours.
Every home is different, so we give free, no-pressure quotes. Call 509-995-6989 or request a quote online.
