Commercial roof cleaning protects the buildings Shoreline businesses depend on. Flat, low slope, and pitched commercial roofs all grow moss and algae in our damp climate, and buildup can damage membranes and clog drainage.
We tailor our soft wash approach to each commercial property, schedule around your operations, and can build a maintenance plan that keeps multiple Shoreline roofs in good condition all year.

Soft wash methods tailored to every commercial roof type.
We work around your hours to limit disruption.
Maintenance schedules that cover larger Shoreline sites.
Proudly serving Shoreline, Lake Forest Park, Kenmore, Edmonds, Mountlake Terrace and Bothell for 12+ years.
From soft wash moss removal to preventative treatments and gutter care, our services are built around one goal: keeping Shoreline roofs healthy in a climate that constantly works against them. Explore what we offer below.

Beyond Shoreline, we bring soft wash roof cleaning and moss removal to neighboring communities that share the same coastal moisture and heavy tree canopy. Whether your roof is shaded by tall conifers or sits in an open lot, our methods are built for the way moss grows across this region.
Frequently Asked Questions
Roof Cleaning can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
In Shoreline's coastal Pacific Northwest climate, most asphalt shingle roofs need a soft wash moss treatment every 12 to 18 months. Tree-shaded properties near Boeing Creek and Innis Arden hold moisture longer and may need attention sooner.
Yes. Moss lifts and curls asphalt shingles as it spreads under them, trapping moisture against the roof deck. Left untreated through Shoreline's wet winters, it shortens roof life and can lead to leaks and premature replacement.
We do not pressure wash asphalt shingle roofs. High PSI strips protective granules and voids most manufacturer warranties. We use a low pressure soft wash method that kills moss at the root without damaging the shingle surface.
Pricing depends on roof size, pitch, moss severity, and canopy coverage. We provide a clear written quote after assessing your property, so Richmond Beach and Ridgecrest homeowners know the full cost before any work begins.
No. We protect landscaping and rinse surrounding areas as needed. Our soft wash solutions break down moss safely, and we take care around gutters and downspouts that drain toward Shoreline's mature plantings.
With a proper soft wash and a preventative treatment, most Shoreline roofs stay clear for 18 months or longer. Adding zinc strips slows regrowth further, especially on north facing slopes shaded by tall conifers.
Yes. We service commercial and multi unit properties throughout the Shoreline area, tailoring our soft wash approach to flat, low slope, and pitched commercial roofs.
We schedule around your operations and work efficiently so Shoreline businesses see minimal disruption while their roofs are cleaned and protected.
Shoreline's damp climate grows moss and algae on commercial roofs just as it does on homes, and buildup can damage roofing membranes and clog drainage over time.
Yes. We are equipped for larger Shoreline commercial properties and can develop a maintenance schedule that keeps multiple roofs in good condition year round.

They explained exactly why pressure washing was wrong for our roof and used a soft wash instead. The moss is gone and our shingles look great. You can tell they know Shoreline roofs.

Our north facing roof was covered in moss after years of shade. They treated it carefully and added zinc strips. Months later it is still clean. Honest and professional throughout.
