Roofing in Greenbrae, CA

Serving Greenbrae and Surrounding Areas

Mill Valley’s coastal climate creates three major roofing issues I see every day. First, the persistent fog and morning moisture cause moss and algae to thrive on asphalt shingles and wood shakes, leading to premature deterioration if left unchecked. Second, heavy winter rains from Pacific storms exploit any weak spot—cracked flashing, missing shingles, or deteriorated seals around skylights—resulting in leaks that damage interiors. Third, the combination of humidity and temperature swings promotes wood rot in older homes, especially in the eaves and soffits of Craftsman cottages and mid-century moderns. I address these problems with annual inspections, moss treatments, and proactive repairs that extend your roof’s life. For example, I install copper or zinc strips to inhibit algae growth, and I use ice-and-water shield in valleys and low-slope areas where water pools. If you’ve noticed water stains on your ceiling or curling shingles in your attic, don’t wait—call me at (415) 234-7891 for a free inspection. I’ll identify the root cause and recommend the right fix, whether it’s a simple repair or a full replacement.
