Washington Lifetime Roofing | Roofing Services in Auburn, WA 98001

In our Auburn climate, skylight leaks are often caused by failed sealant or flashing due to thermal expansion and contraction, or debris buildup in the drainage channels. We fix this by carefully removing the old sealant, inspecting and repairing the flashing, clearing all channels, and applying a new, high-grade polyurethane sealant designed for our wet winters to ensure a watertight, long-lasting seal.

We use a professional, low-pressure soft wash system with EPA-approved, biodegradable cleaning solutions. This method safely kills the algae and moss at the root and rinses away the stains without the high-pressure damage that can strip protective roof granules. For long-term protection, we can also apply a zinc or copper strip treatment at the roof's ridge to inhibit future growth.

Absolutely. A leaking skylight can lead to hidden water damage in your attic, ceiling, and walls, promoting mold and wood rot. Algae stains, while often cosmetic initially, trap moisture against the shingles, accelerating granule loss and shortening your roof's lifespan. Addressing these issues promptly with a professional repair and cleaning service helps prevent costly structural damage and preserves your roof's integrity.
