Roof Moss & Algae in Washougal, WA

Washougal shares the Columbia River corridor’s wet winters and mild temperatures — conditions moss loves. Roofs that stay shaded or collect needle and leaf debris stay damp longer, which speeds growth. Dark algae streaks and green moss along edges are common; ignoring them lets moisture sit against the shingles.

Washougal roofs that face the Gorge take hard east winds in winter. Homes on wooded lots along the Washougal River stay shaded and wet, and that’s where moss grows thickest. A gentle soft wash clears moss and algae from either kind of roof without forcing water up under the shingles.

Soft Wash Protection for Washougal Shingles

High pressure can strip asphalt granules and drive water under shingles. Soft washing lets the solution do the work at low pressure. After treatment, remaining moss often continues to loosen and rinse away with later rain.

We protect landscaping as we work. Owner Dakota Grindland’s crew also works throughout Vancouver, Camas, Ridgefield, and Battle Ground.

Gutter cleaning is included with the roof soft wash, and you can add house soft washing on the same visit. Method overview: Vancouver roof soft washing.

Questions & Answers About
Roof Washing in Washougal, WA

How often do Washougal roofs need soft washing?

Every couple of years is typical; heavier tree cover or persistent shade may mean sooner.

Is soft washing safe for asphalt shingles?

Yes — that is why we soft wash instead of pressure washing roofs.

Do you clean gutters at the same time?

Yes. Gutter cleaning is included with our roof soft wash.

How much does roof washing cost in Washougal?

Roof washing is priced starting at $495, and gutter cleaning is included with a roof soft wash. The final price depends on the size and pitch of the roof, how much moss and algae is on it and how easy it is to reach. We give free on-site estimates in Washougal and the rural areas around it, including homes out Washougal River Road. Call or text (360) 852-5589 to set one up.

Do you rinse the roof after the soft wash?

No. The cleaning solution is left on the roof to keep working, and the rain rinses it off over time. We don’t rinse with high pressure, because Gorge wind and rain already work hard on Washougal roofs and high pressure strips shingle granules. Light algae usually fades quickly, while thicker moss dies in place and keeps washing away with the rain over the following weeks.

What kinds of roofs do you clean?

We soft wash asphalt shingle roofs and tile roofs. Tile roofs are cleaned from a ladder when possible, so we confirm the plan at the estimate. We don’t clean metal roofs or cedar shake roofs. On steep roofs we work in a harness, and if a roof is too steep to work safely, we will tell you and decline the job. Call (360) 852-5589 with questions about your roof.

Will the cleaning solution hurt my plants?

We protect your landscaping before, during and after the job. We wet down plants, beds and lawn below the roofline before we start, keep them rinsed while we work and wet them again afterward. Tell us about any delicate plants or garden beds under the eaves during the free estimate, and we will plan around them. Please also move cars and patio furniture away from the house before we arrive.
