Local crews. Brush moss removal that is safe for shingles. Trusted by Portland-metro homeowners.
Portland's mild, wet winters grow roof moss fast. We remove it by hand with brush cleaning, never pressure washing, then treat the roof to slow regrowth. Licensed and insured in Oregon.
Moss holds water against the shingles long after Portland's rain stops. That trapped moisture works under the shingles and into the roof deck, where it slowly rots the wood and invites mold.
As moss thickens it pries up shingle edges and breaks the weather seal, letting wind-driven rain underneath. Left unchecked, it takes years off an otherwise healthy roof.
“All Seasons cleaned our gutters inside and out, removed moss, and applied moss treatment. The price was in line with other companies, but Paul was more thorough during the estimate and responsive with follow up questions a day or two later. The job went quickly and the gutters and roof look great.”

Our Methodology
We start with a thorough roof inspection to assess the extent of moss growth, check for underlying damage, and identify trouble spots where moisture collects.
We apply a professional-grade, eco-friendly moss treatment solution that penetrates deep into the root system, killing moss at the source without damaging your shingles.
Using gentle brush techniques and careful hand-removal, we clear all dead moss and debris from your roof surface, valleys, and ridgelines.
We apply a long-lasting preventative treatment that inhibits future moss regrowth, protecting your roof for months after service.
A final walkthrough ensures your roof is clean, gutters are clear, and we provide maintenance recommendations to extend the life of your roof between treatments.
Moss is a recurring problem in this climate, not a one-time fix, so the method and the follow-up both matter. We have removed moss from Portland-metro roofs for over a decade and we know where it hides: north and west slopes, shaded valleys, and roofs under heavy fir and maple canopy take the worst of it. We lift the moss off by hand with brush cleaning, never pressure washing, so the granules that protect your shingles stay intact. Then we can treat the roof to slow regrowth, and we stand behind that treatment. Many homeowners keep us on a yearly schedule so small regrowth gets handled before it spreads back across the slope and turns into another heavy infestation. We work carefully around flashing, skylights, and gutters, clean up all the debris, and give you an honest read on the condition of the roof.
