Roofing in Stinson Beach, CA

Serving Stinson Beach and Surrounding Areas

Every Mill Valley roof faces the same three enemies: moisture, moss, and age. Our coastal fog delivers a fine mist that seeps under lifted shingles and into cracked flashings. Winter rains—averaging 50 inches per year—pool on flat sections and run behind gutters. And the redwood canopy drops leaves and needles that hold damp against the roof deck, inviting rot.

Moss is our signature problem. It grows on north-facing slopes and under tree cover, lifting shingle edges and trapping water. Left unchecked, it can double the weight load on your roof and cause leaks within two seasons. We treat moss with zinc strips and low-pressure washing, then install preventive measures during re-roofs.

Age is the third factor. Many Mill Valley homes were built in the 1950s-60s with original asphalt shingles that are now reaching 25-30 years. Those roofs are brittle, curling, and losing granules. A roof inspection from us will tell you exactly how much life remains. If you see dark streaks, curling edges, or granules in your gutters, call us at (415) 234-7891. We'll climb up and give you a straight answer—no pressure, just facts.
