Zinc strip installation adds long term moss defense to your Shoreline roof. Mounted near the ridge, the strips release trace zinc ions every time it rains, and our frequent rainfall carries that protection down the slopes.
This passive, low maintenance solution is ideal for the long shaded roof faces common across Shoreline, slowing moss return between soft wash treatments and helping preserve your shingles.

Installed near the ridge so rain carries protection across the whole roof.
Works automatically with every Shoreline rainfall, no maintenance needed.
A proven, low profile way to slow moss on Pacific Northwest roofs.
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.
Zinc strips release trace metal ions when it rains. As Shoreline's frequent rain washes over the roof, those ions create a surface that resists moss and algae growth below them.
We install zinc strips near the ridge so rainwater carries protection down the entire slope, which is ideal for the long shaded roof faces common in Shoreline neighborhoods.
They reduce regrowth but do not replace periodic maintenance. Zinc strips slow moss return so Shoreline roofs stay cleaner between soft wash treatments.
Installed correctly, zinc strips are low profile and do not damage shingles. They are a long proven, low maintenance option for moss prone Pacific Northwest roofs.
