Roof Cleaning in Thurston County, WA
Soft-wash roof cleaning that kills moss and algae at the root — the method shingle manufacturers actually recommend, not a pressure washer that voids your warranty.
Thurston County’s mix of dense fir canopy and marine air off Puget Sound is exactly what moss and algae need to spread. Tree-shaded lots in Olympia and Lacey, riverside homes in Tumwater, and the open prairie properties around Yelm, Tenino, and Rochester all deal with the same wet-season math: roofs that don’t get full sun stay damp for hours after every rain, and that damp window is when growth takes hold. We soft-wash roofs across every one of those communities, using the method shingle manufacturers actually recommend, not a pressure washer that voids your warranty.
Pine needles and moss built up under Thurston County’s tree canopy — the exact conditions we treat every day, county-wide.
The Climate Problem
Why Thurston County Roofs Grow Moss Faster Than Most
Thurston County sees roughly 56 inches of rain a year, concentrated in a wet season that runs October through May. Dense evergreen cover across Olympia, Lacey, and Tumwater means many roofs take four to six hours to dry out after a storm — that extended damp window is exactly what moss and algae need to establish. Left alone, moss lifts shingle edges and traps water against the deck; algae’s black streaking is cosmetic but signals the same damp conditions doing quieter damage underneath.
How It Works
Our Soft-Wash Process
The same low-pressure method shingle and shake manufacturers recommend — never a pressure washer on your roof.
Debris Removal
We start by clearing loose debris off the roof and breaking up big moss chunks by hand — the heavy lifting before any treatment goes down.
- Loose leaves, needles, and branches cleared from the roof
- Large moss chunks broken up and removed by hand
Clear & Rinse Gutters
We clear out gutters and downspouts and flush them through, so runoff from the roof actually drains instead of backing up against your fascia.
- Gutters and downspouts cleared of debris
- Flushed through to confirm water flows freely
Treat & Kill Moss
We apply a soft-wash treatment formulated to kill moss and algae at the root, at low pressure — never a pressure washer that can void your shingle warranty.
- Soft-wash treatment applied to kill moss and algae at the root
- Low-pressure method safe for shingle, tile, and metal roofs
Clean Up Surrounding Property
We rinse down siding, walkways, and landscaping that caught overspray, and haul away all the moss and debris — so the only thing you notice is the clean roof.
- Siding, walkways, and plants rinsed of any overspray
- All moss and debris hauled away before we leave
What We Clean
Every Roof Type, Cleaned the Right Way
Different materials need different care — here's how we approach each one in Thurston County's wet climate.
Asphalt Shingle
Thurston County's most common roofing material. Soft-washing lifts moss and black algae streaks without loosening the protective granules.

Concrete and clay tile hold up structurally but trap moss in their ridges. We hand-clear buildup so glazed and painted finishes stay intact.

Standing-seam and metal shingle roofs need the gentlest touch. We use non-acidic, metal-safe treatments that won't strip factory coatings.
