Moss is the quiet killer of Oregon roofs. It lifts shingle edges, holds moisture against the surface, and accelerates granule loss. We remove it without pressure-washing damage, then apply preventive treatments and hardware that keep it from coming back.
Key benefits
No high-pressure washing — we protect the granules
Manufacturer-approved treatments safe for plants and pets
Zinc or copper strip installation for ongoing prevention
Gutter and valley debris clearing included

PNW-specific
Built for Oregon's climate
Every choice — from materials to install details — is made with Pacific Northwest weather in mind.
Shade & tree cover
North-facing slopes under Oregon firs stay damp for months. Those areas need treatment on a shorter cycle than the rest of the roof.
Timing the treatment
Late spring and early fall give treatments the dry window they need to work before the wet season returns.
Protecting the warranty
Aggressive cleaning voids most shingle warranties. Our methods keep your manufacturer coverage intact.
