What does a new roof cost in San Jose?
We don't publish a single San Jose price, because roofs vary too much for one to be honest. Remodeling magazine's 2025 Cost vs. Value report puts a midrange 3,000-square-foot asphalt-shingle replacement in the San Francisco metro at roughly $38,000, and a metal replacement of the same size at roughly $65,000. That is a studied average for a defined job, not a quote for your house; request a free written estimate for your exact price.

How does San Jose compare with the rest of the Bay Area?
Census figures put San Jose's median home at 1976, close to Santa Clara County's 1975 median. The city's scale means every roof type shows up: tile in the hills, Eichler flat roofs, and miles of 1960s to 80s tract shingles.
What's the permit process in San Jose?
San Jose reroof permits are issued online through SJPermits.org, and plan review applies only when required.
What about fire ratings for a San Jose roof?
Wildfire exposure matters mainly on San Jose's hillside edges: the east foothills, Almaden and Evergreen. 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 Jose require a cool roof?
San Jose is in Energy Commission climate zone 4 (CEC), which is one of the zones with cool-roof rules for qualifying reroofs, steep-slope and low-slope alike. Ask your roofer for a rated product and the CRRC label (CEC cool-roof guide).
