Roofing in Berkeley, CA

Serving Berkeley and Surrounding Areas

Berkeley’s climate and topography create specific roofing problems. The marine layer fog and morning moisture keep roofs damp for hours, which can seep under lifted shingles and wick into the decking below. Over time, that moisture causes rot and decay in the wood substrate, especially on older homes with original sheathing. Winter storms bring heavy rain to hillside properties, and wind-driven rain can erode flashing and work its way into vulnerable valleys. Dry summers with heat waves accelerate granule loss on asphalt shingles, leaving the mat exposed to UV damage and end-of-life wear. In the Berkeley Hills, homes face higher wind exposure, which can lift shingles and compromise the starter course. We also see sagging rooflines on older Craftsman bungalows where framing has settled over decades. Our repair process addresses the root cause, not just the leak. We replace rotted decking, reseal flashing, and reinstall shingles with ring-shank nails and staggered courses that hold up to the elements. For flat or low-slope roofs on mid-century modern homes, we apply self-adhered membranes that prevent water intrusion. We’ve fixed roofs near the Campanile, on the slopes above Lake Anza, and in the flats of West Berkeley. If you notice peeling paint on the underside of eaves, water stains on ceilings, or a sudden spike in your heating bill, call us before the damage spreads. We’ll inspect, identify the failure mode, and give you a clear plan—whether that’s a targeted repair or a full replacement using materials suited to Berkeley’s unique climate.
