Roofing in Berkeley, CA

Berkeley roofs live a harder life than most. The marine layer rolls in off the bay and settles on North Berkeley and the Claremont hills, keeping shingles damp for weeks at a time. That constant moisture seeps under lifted tabs and wicks along the decking, turning small nail pops into rot that spreads before you notice a single drip inside. Winter storms off the Pacific hit the west-facing slopes of the Berkeley Hills with heavy rain, and the dry summers that follow bake the same shingles until they flake and spall. We've seen the full cycle on Early 1900s Craftsman bungalows with wood shingle roofs, on Mid-century modern homes built in the 1950s and 1960s, and on Victorian and Edwardian houses from the 1890s-1910s that still carry their original roof structure.

Our crews tear off the old layers down to the substrate — no recover work that hides existing decay. We install self-adhered underlayment at every valley and penetration, hand-seal the starter course and field course, and set every shingle with ring-shank nails so the wind can't pull them loose. Staggered courses keep water moving down the slope instead of finding a seam to exploit. We also refit multi-family buildings in West Berkeley and the flats, where tenant disruption matters. We schedule tear-offs during reasonable hours, contain debris with chutes and magnets, and prioritize emergency leak calls so a small drip doesn't become a ceiling collapse during a storm.
