Pressure washing restores the hard surfaces around your Shoreline home. Driveways, walkways, and patios collect moss and algae in our damp shade, becoming slippery and discolored over time.
We pressure wash these surfaces at the correct pressure to clean safely, and we are clear about one thing: asphalt roofs are never pressure washed, only soft washed, to avoid stripping granules and voiding warranties.

Restores traction and appearance to slippery shaded surfaces.
Matched to each surface so nothing is etched or gouged.
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.
We pressure wash hardscapes like driveways, walkways, patios, and concrete around Shoreline homes. We do not pressure wash asphalt roofs, which require gentle soft washing instead.
High pressure blasts away the protective granules on asphalt shingles and can void warranties. Shoreline roofs need a low pressure soft wash to stay protected.
Handled by professionals at the correct pressure, no. We adjust technique to the surface so Shoreline driveways and patios come clean without etching or gouging.
Yes. Shoreline's damp shade lets moss and algae build on walkways and patios, and pressure washing safely restores traction and appearance to those hard surfaces.
