Our Mill Valley roofs face three persistent problems that I see every day. First, coastal fog and morning moisture create a constant damp environment that feeds moss, algae, and lichen on asphalt shingles and wood shakes. If left unchecked, that growth traps moisture against the roof deck and can cause rot within three to five years. Second, heavy winter rains from Pacific storms test every flashing joint and valley—I’ve repaired countless leaks where water backed up behind clogged gutters or found its way through deteriorated step flashing around chimneys and skylights. Third, the mild temperatures and low snowfall risk might sound easy on roofing, but the freeze-thaw cycles we do get can crack aged sealants and expand small gaps into major leaks. I address these issues with regular inspections, zinc strip installations to inhibit moss, and proper attic ventilation to reduce moisture buildup. For older homes—especially the mid-century moderns and Craftsman cottages common in Mill Valley—I also recommend upgrading to Class 4 impact-resistant shingles that handle falling branches and hail. Don’t wait for a leak to show up inside your living room. Call (415) 234-7891 for a thorough roof assessment and honest advice.
