Roofing in Corte Madera, CA

Serving Corte Madera and Surrounding Areas

Mill Valley's coastal climate creates specific roofing issues I see every week. The frequent fog and morning moisture keep roofs damp for hours, encouraging moss and algae growth on asphalt shingles. I've pulled off entire moss-covered roofs on Sycamore Avenue where the granules had washed away completely. Heavy winter rains from Pacific storms test every flashing and valley—I've found leaks at pipe boots and chimney crickets that were installed just two years prior. The redwood trees that give our neighborhoods their character drop needles and leaves into gutters, causing ice dams in the rare freeze and water backup under shingles. On mid-century modern homes with low slopes, ponding water is a constant threat; I've had to add tapered insulation panels to get proper drainage. The salt air from the Golden Gate National Recreation Area corrodes exposed metal flashings and vents on homes in Strawberry and Tamalpais Valley. And the steep hillsides around Mount Tamalpais mean high wind exposure—I've replaced entire ridge lines where wind had lifted shingles and torn underlayment. These aren't problems you'll see in the Central Valley. They're Mill Valley problems, and I solve them with materials and methods built for this specific microclimate.
