What is the cool-roof requirement for residential re-roofing in San Jose?
California's Title 24 requires that most residential roof replacements in the state meet minimum solar reflectance and thermal emittance values defined by the California Energy Commission.

Your roofing contractor should be able to confirm that proposed materials carry a qualifying CRRC label before a permit is submitted to the city.
Do I need a permit to replace my roof in San Jose?
Yes. The City of San Jose Building Division requires a permit for most roof replacements, including changes to roof covering material, deck repairs above a certain square footage, or any structural modification. Solar installations on the roof surface have their own permit pathway. A local roofer who pulls permits regularly knows current plan check timelines, which can run several weeks for more complex residential scopes.
How does seismic activity affect residential roofing decisions in San Jose?
While roofs rarely fail structurally in earthquakes unless the underlying frame is compromised, seismic activity can loosen step flashing at chimneys and dormer walls over time through repeated micro-vibration. A thorough residential roof inspection in San Jose should include hand-testing chimney and wall flashings for movement, as these represent the most common post-seismic leak origin in otherwise sound roofs.
