Roofing in San Quentin, CA

Serving San Quentin and Surrounding Areas

Living in Mill Valley means your roof faces constant moisture from coastal fog and heavy winter rains. I see three recurring issues: first, moss and algae buildup that traps moisture against shingles, leading to rot and reduced lifespan. Second, failing flashings around skylights, chimneys, and valleys—these are the most common leak sources after a storm. Third, inadequate attic ventilation that causes condensation and ice dam formation, even in our mild winters. I address each problem with specific solutions: zinc strips to prevent moss, custom-flashed penetrations using marine-grade sealants, and ridge vent installations that meet current California energy codes. If you spot dark streaks, curling shingles, or water stains on your ceiling, call me at (415) 234-7891. I’ll come out, inspect your roof, and give you a straightforward assessment—no pressure, just honest advice.
