What does a new roof cost in San Francisco?
There's no honest single price for San Francisco. A published midrange benchmark for the San Francisco metro, from the 2025 Cost vs. Value report, is roughly $38,000 for a 30-square asphalt-shingle replacement and roughly $65,000 for metal. Your own roof's price will differ; a free written estimate is the only real number. Our cost guide explains the drivers, and the roof size estimator gives you squares to compare bids.
How does San Francisco compare with the rest of the Bay Area?
Census figures put San Francisco's median home at 1946, decades older than the counties around it, and the typical roof is a flat section behind a parapet rather than a sloped shingle roof.
What's the permit process in San Francisco?
DBI handles reroofing permits; licensed C-39 contractors can apply online for jobs with no structural work, and anything with decking or framing goes over the counter (SF.gov).
Is my San Francisco home in a fire hazard zone?
Wildfire zoning rarely drives San Francisco roof choices, but it's worth checking your address. CAL FIRE's hazard zone maps show your zone, and state law requires Class A when more than half the roof is replaced within a year in a very high zone.
Does San Francisco require a cool roof?
Not under the prescriptive rules: climate zone 3 (CEC) sits outside the zones where reroofs must meet cool-roof minimums. Reflective products are optional (CEC cool-roof guide).
