Cedar shake demands the gentlest care, and Kent's moisture rots untreated cedar fast. We use very low pressure and wood-safe solutions to clear moss without splitting the shakes.
Cedar is soft and porous, so aggressive methods ruin it. Our process protects the wood while removing the growth, then treats it to help the shakes shed water and resist moss.

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.
Cedar demands the gentlest approach, so we use very low pressure and wood-safe solutions to clear moss and algae without splitting or eroding the shakes.
Cedar is soft and porous, so the aggressive methods used elsewhere ruin it. Our process protects the wood while removing damaging growth.
It does. Kent's constant moisture rots untreated cedar quickly, so we clean and then apply treatment that helps the wood shed water and resist moss.
We can revive the appearance of weathered cedar by removing built-up moss and grime, though severely rotted shakes may need replacement first.
