Free EstimateRoof Cleaning in Mill Creek, WA
Moss, algae, and lichen thrive on Mill Creek roofs thanks to the Pacific Northwest's combination of shade, rain, and humidity. These organisms aren't just ugly — they trap moisture under shingles, accelerate granule loss, and can void your manufacturer's warranty. Left untreated, a moss-covered roof deteriorates years faster than a clean one. Our professional soft-wash roof cleaning kills growth at the cellular level without the high pressure that damages roofing materials.
Velocity's Mill Creek roof cleaning uses a low-pressure, biodegradable treatment that is safe for composition shingles, cedar shake, tile, and metal roofing. We apply the solution gently, allow it to dwell for maximum effectiveness, and rinse away dead organic matter. The result: a clean roof, preserved warranty coverage, and 5–10 extra years of life from your roofing investment. We inspect the entire surface and walk through results with you before we leave.

What Our Customers Say
Real Results. Real Homeowners.
“Our driveway looked brand new — we couldn't believe the difference. The crew was professional, on time, and cleaned up after themselves. Neighbors have already asked for the number.”
“Had moss covering half our roof. Velocity removed everything without any damage to the shingles. Six months later it's still clean. Worth every penny compared to what a new roof would cost.”
“We hired them before listing our home. The soft wash made the siding look 10 years newer. Our realtor said it was the best pre-listing investment we made. Sold in four days.”
