I see three roof issues more than any other in Mill Valley. First, moss and algae growth. Our coastal fog keeps roofs damp for hours each morning, and that moisture lets moss take hold on north-facing slopes and shaded areas. If left unchecked, moss lifts shingles and traps water, leading to rot. I recommend annual cleaning and zinc strip installation to prevent regrowth. Second, flashing failures around chimneys and skylights. Many homes here were built in the 1950s-70s, and original flashing often uses thin galvanized steel that corrodes after 20-30 years. I replace failing flashing with heavy-gauge copper or stainless steel—materials that stand up to our wet winters. Third, valley leaks where two roof planes meet. Heavy rain from Pacific storms concentrates in these channels, and if the underlayment or metal valley is compromised, water finds its way into your attic. I inspect every valley during a roof inspection and reinforce them with ice-and-water shield. If you notice dark spots on your ceiling, peeling paint near the roofline, or granules in your gutters, call me at (415) 234-7891. I’ll come out, diagnose the problem, and give you a clear repair or replacement plan.
