Few places grow roof moss like Seattle, where damp shade and tree cover let it spread fast. Left alone, moss lifts shingles and traps moisture, so we remove it carefully and treat the surface to slow regrowth.
Our approach is gentle on your roofing material while targeting the moss at its root, a balance that matters on the older roofs common throughout Seattle neighborhoods.

We remove moss without aggressive scraping that can damage shingles on older Seattle roofs.
A targeted treatment slows regrowth in the shaded, damp conditions moss loves.
Loosened moss and debris are cleared from the roof, gutters, and grounds before we finish.

Our service reaches well beyond Seattle city limits into the communities that share the same wet climate and heavy tree coverage. No matter which side of Lake Washington you call home, our crews bring the same local expertise and careful work to every property.
Frequently Asked Questions
Gutter Cleaning can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
With Seattle's heavy rainfall and dense fir, cedar, and maple coverage, most homes need cleaning twice a year, typically late spring after oak tassels drop and again in late fall once the leaves finish coming down.
The Puget Sound climate keeps debris damp year round, so cedar needles, fir cones, and moss break down into a heavy sludge instead of drying out and blowing away. That mat traps water and clogs downspouts well before a single visible blockage forms.
Yes. When water overflows the gutter it runs down the fascia and pools against the foundation, which is a real concern on Seattle's many sloped lots and older homes. Keeping gutters clear protects your roofline, siding, and basement from costly water intrusion.
We clear moss and organic buildup from the gutters and roofline edge during service, which is common on shaded Seattle roofs. For heavier roof moss we recommend our dedicated moss removal treatment to keep it from returning.
Ladder falls send thousands of homeowners to the hospital every year, and wet Pacific Northwest roofs make footing unpredictable. Our crews are trained, insured, and equipped to work safely at height so you never have to climb a slick ladder.
We serve homes across Seattle including Ballard, Queen Anne, Capitol Hill, Wallingford, and Green Lake, along with nearby cities like Bellevue, Renton, Shoreline, Kirkland, and Burien.
Damp shade, tree cover, and steady moisture create ideal moss conditions, which is why Seattle roofs grow it far faster than homes in drier regions.
Our careful method avoids the aggressive scraping that harms roofing, so we remove moss while protecting the shingles underneath.
Our preventive treatment slows regrowth significantly, though shaded Seattle roofs benefit from periodic follow up to stay clear long term.
Yes. Moss lifts and separates shingles and traps moisture against the roof, shortening its life if left untreated in our wet climate.

They cleared years of cedar buildup from our Ballard gutters and flushed every downspout. Water finally drains the way it should, even in a downpour.

Moss had taken over our roofline in Wallingford. The crew was thorough, on time, and showed me photos of everything they removed. Highly recommend.
