Roofing in San Francisco

Roofing challenges unique to the Bay Area

Bay Area roofs don't face snow or hail country, but they take a beating all their own — and a roofer who learned the trade somewhere else often misses it. We build every job around the pressures that actually damage roofs here:

• Karl the Fog & the marine layer. In the Sunset, the Richmond District, Daly City and Pacifica, roofs stay damp nine months a year — moss and lichen take hold, fasteners corrode, and fascia rots quietly behind the gutters.
• Winter atmospheric rivers. Our rain arrives in concentrated multi-day storms after months of dry weather, so a small flaw that hid all summer suddenly takes days of wind-driven water at once.
• Flat rowhouse roofs. The city's Victorians and Edwardians carry flat torch-down and TPO roofs behind parapet walls with tight access — a specialty trade that most suburban shingle outfits simply don't do well.
• Salt air on the Coastside. From Pacifica to Half Moon Bay, salt and wind-driven rain corrode flashing and fasteners years ahead of schedule.
• Diablo winds & wildfire country. Dry offshore winds rake the East Bay hills and North Bay each fall, and homes in WUI zones need Class-A fire-rated roof assemblies under California's Chapter 7A.
• Title 24 & SF DBI permits. Low-slope reroofs need cool-rated materials statewide (climate zone 3 included), San Francisco reroofs are permitted through the Department of Building Inspection, and historic districts add review — we build it in, not bolt it on.

That local knowledge is the difference between a roof that's patched and a roof that's actually fixed. Browse our roofing guides for honest, Bay Area-specific answers, or see what we do in your area.

One roofer for flat, shingle and tile

Plenty of roofers only really do pitched shingle. We lead with the roofs this city is actually made of: flat and low-slope torch-down and TPO rowhouse roofs; architectural asphalt shingle across the Peninsula, East Bay and North Bay; and clay, concrete and Spanish tile on the region's revival homes. Whether you need a seam re-welded, a leak traced to its real source, or a full Title 24-compliant re-roof with SF DBI permits and financing, it's the same licensed, insured crew and the same honest written price.
