Lichen bonds tightly to roofing and is far tougher than moss to remove. We treat and soft wash it carefully to break its hold without harming the surface underneath.
Lichen pries at the granule layer and traps moisture, weakening roofs already stressed by Kent's wet climate. After removal we apply a preventive treatment to slow its return.

We treat lichen to loosen its tight grip before gently soft washing it away.
Our method clears lichen without harming the shingle or shake surface beneath.
A preventive treatment makes the roof less hospitable to lichen regrowth.

Our service reaches well beyond Kent into the neighboring communities where the same wet climate drives heavy moss and algae growth. Whether your home backs up to greenbelt in Covington or sits on an open lot in Federal Way, we bring the same careful soft wash approach to every roof.
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.
With our wet Western Washington climate, most Kent roofs benefit from a professional cleaning every 18 to 24 months. North-facing slopes and roofs shaded by Douglas firs hold moisture longer, so they often need attention sooner to stop moss from rooting under shingles.
We use a low-pressure soft wash with treatments that break down moss and algae at the root rather than blasting them off. High pressure strips granules from composition shingles and splits cedar shakes, so for Kent roofs we rely on chemistry and gentle rinsing, not force.
Kent sits in a high-rainfall pocket of King County with long damp seasons from October through March. Cool temperatures, tree cover, and constant moisture create ideal conditions for moss, algae, and lichen, especially on shaded and north-facing sections of a roof.
Yes. Moss traps water against the roof deck and lifts shingle edges, which leads to rot and early failure. Removing growth and applying preventive treatment protects the underlayment, helps preserve manufacturer warranties, and adds years of usable life to the roof.
We do. Cedar shake, composition shingle, metal, and tile all behave differently, so each gets a tailored approach. Cedar needs careful low-pressure work to protect the wood, while metal and tile in the Kent area respond well to targeted soft wash methods.
We take care to protect the plants and gardens around your Kent home. We pre-wet vegetation, control runoff, and rinse surrounding areas after treatment so your landscaping stays healthy while the moss and algae on the roof are dealt with properly.
Lichen is a tough growth that bonds tightly to roofing, so we treat and soft wash it carefully to break its hold without harming the surface.
Lichen anchors into the shingle surface far more firmly than moss, so it needs treatment time and a gentle approach rather than brute force.
It does. Lichen pries at the granule layer and traps moisture, which over time weakens Kent roofs already stressed by the wet climate.
Yes. After removal we apply a preventive treatment that makes the surface less hospitable to lichen and slows its return through the damp season.
