Why Soft Wash
Pressure Washing Ruins Roofs. We Do Not Do It.
A pressure washer will strip moss off a roof in an afternoon. It will also strip the ceramic granules that give asphalt shingles their UV protection, force water under the courses, and in many cases void the manufacturer warranty outright. The roof looks clean and ages five years in one visit.
Soft washing does the opposite. We apply a biodegradable solution at roughly garden hose pressure, let it kill the moss, algae and lichen at the root, then rinse. The organism dies rather than being torn off, which is why a soft washed roof stays clear far longer than a blasted one. It is the method most shingle manufacturers actually specify.
We work asphalt shingle, cedar shake and tile across Columbia County and the Portland Metro area, and we tell you up front if your roof is past cleaning and into replacement.
Included As Standard
What A Roof Clean Includes
One price, one visit, no line items appearing afterwards.
Full Soft Wash Application
Biodegradable solution applied across the whole roof plane at low pressure, not just the patches you can see from the driveway.
Moss Treatment Included
Root level moss kill is part of the roof cleaning rate, never billed as an extra. Comes with a limited regrowth warranty.
Valley And Gully Clearance
Built up debris pulled out of valleys and behind chimneys, where the water actually backs up.
Landscaping Protection
Beds and shrubs pre-wet before any solution goes up, then rinsed down once we finish.
Gutter Debris Check
We flag what has washed into the gutters. If it needs clearing we tell you before we leave rather than sending you a surprise.
Before And After Photos
Sent to you when the job is done, so you can judge the result whether you were home or not.
Do You Need It Yet
Five Signs Your Roof Is Ready
Oregon roofs rarely need cleaning every year. These are the markers that say it is time.
- Green moss mats sitting proud of the shingle line, especially on north facing slopes
- Dark streaks running down from the ridge, which is gloeocapsa magma algae rather than dirt
- Crusty grey or pale green patches, which is lichen and needs treatment rather than scrubbing
- Grit collecting at the bottom of your downspouts, meaning granules are already coming loose
- It has been more than two years since the last clean, and your roof sits under fir or maple
Not sure? Text a photo to (971) 328-2122 and we will tell you honestly, including when the answer is that it can wait another year.
Free Written Estimates
How We Price A Roof Clean
Roof cleaning is quoted per property, not from a chart. Send an address and a few ground level photos and you get one written number that does not move afterwards.
What Your Estimate Depends On
- The footprint of the house and how many storeys it has
- Roof pitch, and whether it needs additional fall protection
- How heavy the moss, lichen or algae growth has become
- Roof material, since cedar and tile are handled differently to asphalt shingle
- Access, including ladder footing, gates and how close we can park
What Is Never Charged Extra
- Moss treatment, which is part of a roof clean rather than an add on
- The estimate itself, whether we quote from photos or walk the property
- Landscaping protection, pre-wetting and rinse down
- Debris haul away on a standard job
- Before and after photos sent when we finish
- Our return at no charge if the result is not right

Book It Together
What Homeowners Usually Book With It
Bundling into one visit saves 15 to 20% against booking separately, because we only mobilise once.
Gutter Cleaning
Everything the roof sheds ends up in the gutters, so doing both in one visit is the sensible order. Bundling the two into one visit costs less than booking them separately.

Moss Removal
If the moss has also taken the driveway strip, the walkway or the patio, we treat the hardscape in the same visit.

Common Questions
Roof Cleaning Questions
How much does roof cleaning cost?
Roof cleaning is quoted per property rather than from a chart, because footprint, storey count, pitch, roof material and how heavy the growth is all move the number. Send an address and a couple of photos and you get one fixed written price, usually the same day.
Will soft washing damage my shingles?
No. Soft washing runs at roughly garden hose pressure, which is why shingle manufacturers specify it. The damage risk comes from pressure washing, which strips granules and forces water under the courses.
How long until the moss comes back?
Most Oregon roofs stay clear for one to two years after a soft wash. Roofs under heavy fir cover or with permanent shade come back faster. Our moss treatment carries a limited regrowth warranty.
Do you need to get on the roof?
Only where access requires it. Most of the work is done from ladders and from the ground, which reduces the risk of anyone stepping on brittle shingles.
Is the solution safe for plants and pets?
Yes, we use biodegradable, plant safe solutions and pre-wet and rinse landscaping on every job. Keep pets indoors while we are on site and until surfaces have dried.
Can you clean a roof in winter?
Yes. Oregon winters are mild enough that we work year round, and the off season often means we can be out within a couple of days rather than a couple of weeks.
