Bay Area price bands
Installed, including tear-off and disposal, on a typical 2,000 sq ft roof.
- Architectural asphalt shingle: $18,000 – $30,000
- Standing seam metal: $34,000 – $58,000
- Concrete or clay tile: $32,000 – $62,000
- Flat TPO or torch-down on a rear addition: $12 – $19 per sq ft
Why the Bay Area runs high
Labour rates, prevailing-wage pressure, disposal fees and steep hillside access all push costs above the national average. San Francisco and the mid-Peninsula also see a high share of older homes with two or three existing layers, which adds a full tear-off day and several extra dumpster pulls.
Permits and Title 24
Nearly every Bay Area jurisdiction requires a permit for a full replacement, and California Title 24 cool-roof requirements apply to low-slope and many steep-slope re-roofs in climate zones covering the region. A licensed roofer should pull the permit and specify a compliant product; if a bid does not mention either, treat it as a red flag.
When to book
Late spring and early autumn are the sweet spots: dry weather without the August backlog. Booking in January or February often earns off-season pricing, though the schedule slips with every storm.
