Roofing Contractor in San Rafael
Marin County, CA

East Bay Roofers is the Marin County roofing contractor that San Rafael homeowners and property managers call for heavy rain, fog-belt moss, and fire-zone hillside work. Since 1988, we've handled roof repair, replacement, installation, and emergency service across San Rafael's Dominican, Gerstle Park, and Terra Linda neighborhoods. Here's what makes San Rafael different:

San Rafael is the Marin County seat and the largest city in the county — about 63,000 people spread across a remarkably diverse geography: the downtown valley with its old Craftsman and mission-revival homes, the Dominican and Gerstle Park hillsides draped with live oaks and redwoods, the Terra Linda tract corridor, waterfront neighborhoods along the canal, and the fire-zone hills climbing toward Mount Tamalpais. Each area has its own roofing rhythm.

Our Roofing Work in San Rafael (Since 1988)

East Bay Roofers has been doing work in San Rafael since 1988. We're based in Concord — about 40 minutes across the Richmond-San Rafael Bridge — and Marin has been a core part of our service area from the beginning. A lot of our Marin business comes from homeowners who'd rather work with an East Bay contractor that actually understands Marin conditions than pay Marin-only premium pricing.

I'll tell you a Dominican job that's stuck with me. 2021, a 1940 English cottage-style home tucked into the hillside off Palm Avenue, dripping with live oak canopy. The owner had called three other contractors, all of whom quoted her a straight composition re-roof. When we inspected, we found the original slate roof was still 80% intact under two layers of later composition that had been added as "repairs" over the decades. Vermont gray slate from the 1940s, still sound, still beautiful. We restored the original slate, replaced the broken pieces with salvaged matches, installed new copper valley metal. Total cost was about $12,000 more than the composition re-roof would've been. She told me it was the best money she's ever spent on the house.

San Rafael Climate and Roofing Challenges

San Rafael gets about 29 inches of rain per year — the most of any city in our service area. Marin catches more rainfall than the East Bay because the Mount Tamalpais ridge forces winter storms to drop their moisture as they push inland. Every flashing joint, valley seam, and penetration detail has to handle about 40% more water than a comparable roof in Concord.

• Heavy rain load. 29 inches means ice-and-water shield in every valley, properly flashed chimneys, and oversized gutters are non-negotiable.
• Fog-belt moss. The marine fog keeps west-facing slopes damp most of the year. Without zinc or copper ridge strips, moss colonizes asphalt roofs within 10 years. We install zinc strips as standard on any San Rafael re-roof west of 101.
• Fire zone exposure. Hillside properties on the slopes toward Mount Tamalpais are inside the VHFHSZ. Chapter 7A compliance is mandatory in these areas — Class A assembly, ember-resistant vents, noncombustible gutters.
• Mature tree canopy. Live oaks, redwoods, and eucalyptus drop debris that packs valleys and gutters fast. Leaf guards and oversized downspouts are worth the investment.
• Eichler roofs. Terra Linda's mid-century Eichler homes have distinctive low-slope roofs that need TPO, PVC, or spray-foam — not conventional asphalt shingles.

Permits and Local Rules

Permits are issued through the City of San Rafael Community Development at 1400 Fifth Avenue. Marin County handles permits for unincorporated parcels.

What you need to know:

• Chapter 7A enforcement is strict. Marin cities have been aggressive about fire code enforcement since the 2017–2020 fire seasons. If your property is in the VHFHSZ, expect scrutiny on assembly specs, vent types, and gutter materials.
• Title 24 and Marin amendments. San Rafael follows California Title 24 energy code plus Marin County amendments. Cool-roof requirements apply for replacements over 50% of roof area.
• Eichler-specific. Terra Linda Eichler homes need TPO, PVC, or spray-foam systems. The city plan checkers know what they're looking at.
• Tree protection. San Rafael has strict tree protection ordinances. Heritage oaks and large redwoods require a separate permit if trimming is needed.
• Permit fees typically run $400–$650 for a standard residential re-roof.

Recent San Rafael Projects

Dominican English cottage slate restoration — 2021 — 1940 English cottage off Palm Avenue. Found original Vermont gray slate 80% intact under two layers of composition "repairs." Restored original slate, replaced broken pieces with salvaged matches, new copper valley metal. Cost $12,000 more than a composition re-roof — owner said it was the best money she's ever spent on the house.

The original slate was still beautiful after 80 years. The composition "repairs" added over the decades were the problem — not the slate.
