Excalibur Roofing & Repair | Roofing Services in Shelton, WA 98584

Moisture in your attic often stems from poor ventilation or small, hard-to-find leaks common in our damp climate. Our repair service includes a thorough inspection to identify the source, such as damaged flashing or compromised shingles. We then perform precise repairs and can advise on improving attic ventilation. This targeted approach stops moisture at its source, protecting your insulation's effectiveness and preventing mold growth in your home.

The black stains you see are actually a type of algae (Gloeocapsa magma) that thrives in our humid, shaded environments. It feeds on the limestone in asphalt shingles. We use a professional, low-pressure cleaning solution that safely kills and removes the algae without damaging your shingles. More importantly, we can discuss installing zinc or copper strips at the roof ridge. When it rains, these metals release ions that wash down the roof, preventing future algae growth.

Regular maintenance is key in our area. We recommend a professional inspection at least once a year, especially after fall and winter storms. We'll clear your gutters and downspouts to ensure proper water runoff, check for any moss buildup that can trap moisture, and inspect seals around vents and chimneys. Keeping trees trimmed to reduce shade and debris also helps minimize algae and moisture retention. This proactive care from your local roofer can extend your roof's life significantly.
