San Rafael roofs take a beating. Foggy mornings soak the shingles, afternoon sun bakes them dry, and winter storms push water hard against every flashing and valley. That cycle of wet and dry causes granules to erode, sealants to crack, and decking to rot before you ever see a stain on the ceiling. North Bay Roofing CO knows these Marin County conditions inside out. We're a local roofing contractor that fixes, restores, and replaces roofs across San Rafael — from mid-century moderns in Terra Linda to Spanish Colonial Revival homes near the Civic Center.
Common Roof Problems in San Rafael
Every neighborhood has its own failure modes. Here's what we see most often when we climb onto San Rafael roofs.
- Granule loss — asphalt shingles shed their mineral surface after years of sun and fog, leaving the fiberglass mat exposed to UV degradation and end-of-life wear.
- Flashing failure — corroded or lifted flashing around chimneys, skylights, and valleys lets water wick behind the shingles and seep into the roof deck.
- Ponding water — flat and low-slope roofs on commercial buildings and mid-century homes collect water that never drains, causing the membrane to delaminate and the substrate to rot.
- Storm damage — Pacific storms tear off shingles, bruise others with hail, and drive rain sideways under the eaves, leading to systemic leaks if not addressed quickly.
- Poor ventilation — hot attic air in summer and trapped moisture in winter cause shingles to curl, blister, and buckle from below.
How We Protect San Rafael Roofs
We don't just patch problems — we rebuild the whole system so water stays out for decades.
- Full tear-off and replacement — we strip the old shingles down to the deck, inspect for rot and decay, and install new underlayment, starter course, field course, and staggered courses with ring-shank nails that hold firm in high winds.
- Self-adhered ice-and-water shield — we line the eaves, valleys, and penetrations with a self-adhered membrane that seals around nail heads and prevents water from wicking up the deck.
- Metal flashing and skylight work — we refit and reseal all flashing points, and install skylights with proper curbs and pan flashings so they don't leak in the first heavy rain.
- Gutter installation and repair — we keep water moving off the roofline and away from your foundation, preventing ice dams and erosion along the eaves.
- Insurance claim assistance — we help you document storm damage, work with your adjuster, and make sure the insurance scope covers the full repair.
