S T S Roofing | Roofing Services in Alpine, CA 91903

Alpine's temperature fluctuations and seasonal weather can cause the seals and flashing around skylights to degrade faster than on other parts of the roof. We perform detailed inspections to identify failing seals or improper installation, then provide precise repairs or replacements using materials suited for our local climate to prevent recurring leaks.

We use a safe, professional-grade treatment to remove existing moss without damaging your shingles. More importantly, we address the root cause—often shade and moisture retention—by recommending and performing preventative measures like trimming overhanging branches and ensuring proper roof ventilation to inhibit future growth and protect your roof structure.

First, contain any interior water damage safely. Then, contact us for a prompt inspection. For moss, avoid pressure washing, which can strip granules from shingles. Our local expertise allows us to quickly diagnose whether it's a sealant failure, flashing issue, or moisture problem and recommend the most effective, long-term repair strategy for your Alpine home.
