Which Danville and San Ramon?
The neighboring San Ramon Valley towns in Contra Costa County, California, along Interstate 680 between Walnut Creek and Dublin, not Danville in Virginia, Illinois or Kentucky. Danville's median home was built in 1980 and San Ramon's in 1994 (ACS 2024 5-year), so these are younger roofs than the inner East Bay's. Many are now reaching the end of a first or second covering at about the same time.
What should I verify before hiring in Danville or San Ramon?
Three things, all on the state's license lookup: the license is active, it carries the C-39 roofing class (C-39 details), and workers' comp is listed if the crew are employees. Then read the written contract: California caps the down payment on home improvement work (Business and Professions Code 7159.5).
Do I need HOA approval?
Often. Much of San Ramon, including large master-planned areas, and many Danville subdivisions are governed by homeowners associations with architectural review for roof color and material. Get the association's approval, or its approved-materials list, before signing with a roofer, and ask whether the roofer has worked in your HOA (HOA roof guide).
Tile, cool roofs and permits
Concrete tile is common on newer homes here; leaks often trace to underlayment rather than tile, which makes a lift-and-reset an option (tile guide). Both towns are in climate zone 12 (CEC), so reroofs replacing more than half the roof generally need a rated cool-roof product (CEC). Permits come from the Town of Danville or the City of San Ramon; hillside areas should check CAL FIRE's map.
Where do I find East Bay roof prices?
This page is about who replaces your roof. Price lives on our East Bay cost guide, which covers what moves the number on local homes. We don't publish dollar figures, because a written estimate after an inspection is the only number that fits your roof.
