ROOF CLEANING IN SEATTLE, WA
Ground-level moss treatment and soft wash for all roof types. We kill moss, algae, and lichen at the root — extending your roof's lifespan by 5-10 years. We never walk on your roof.
The Problem
Pacific Northwest roofs take a beating. Moss, algae, and lichen thrive in our wet climate, working their way under shingles, lifting edges, and trapping moisture that accelerates rot. Most homeowners don't realize the damage until they need a $15,000+ roof replacement. And many roof cleaning companies make it worse by walking on your roof and using high pressure that strips granules off composition shingles.
Our Solution
We treat your roof from the ground using professional-grade solutions that kill moss, algae, and lichen at the root. No walking on your roof. No high pressure that strips protective granules. Our treatment penetrates deep, kills growth at the cellular level, and provides long-lasting protection. The dead moss naturally washes away with rain over the following weeks.

ROOF CLEANING FAQ
Why don't you walk on the roof?
Walking on roofs — especially composition shingle roofs — damages shingles, breaks seals, and can void manufacturer warranties. Our ground-level treatment is safer for both your roof and our crew.
How long until I see results?
The treatment begins working immediately. You'll see moss and algae changing color within days. Dead growth naturally washes away with rain over 2-4 weeks.
Will the treatment damage my gutters or downspouts?
No. Our solutions are biodegradable and safe for all gutter materials. We also rinse the roofline and gutters after treatment.
How often should I have my roof treated?
In the Seattle area, we recommend treatment every 2-3 years depending on tree coverage and sun exposure. Heavily shaded roofs may benefit from annual treatment.
