Cedar Roof Treatment

What This Service Involves

Untreated cedar in our climate slowly weathers, and without periodic care it can dry, split, or invite the moss that thrives in Puget Sound shade. Our treatment service restores natural oils and adds water-repellent and fungicidal protection so the wood resists rot, cupping, and biological growth. We begin by cleaning and letting the roof dry, then apply penetrating preservatives formulated for Western red cedar rather than surface coatings that peel. This kind of scheduled maintenance is what allows a cedar roof to reach the long lifespan it is capable of instead of failing early under constant damp. For homeowners who invested in a wood roof, treatment is the most cost-effective way to protect that investment year after year.

Benefits

Replenishes natural oils lost to sun and constant rain exposure; adds fungicidal protection that slows moss and mildew return; water-repellent formula reduces cupping, splitting, and premature rot; penetrating products soak in rather than peeling like film coatings; scheduled upkeep meaningfully extends the years between reroofs

Our Process

1) Inspect the roof for damaged shakes, prior growth, and areas needing repair before treatment; 2) Clean the surface gently and allow the wood to dry fully; 3) Apply penetrating cedar preservative with water-repellent and fungicidal properties; 4) Check coverage on ridges and high-exposure faces and note a recommended re-treatment interval.

What Affects the Cost

Roof size, pitch, and how much surface must be reached safely; condition of the cedar and whether pre-treatment repairs are needed; type and quality of preservative or oil product selected; degree of existing moss or mildew requiring prep before application; access, staging, and protection for surrounding plantings

Best Time of Year

Apply treatment during a stretch of dry, mild weather in summer so the preservative can fully penetrate and cure.
