Roof replacement
in the East Bay
East Bay roofs range from 1940s Berkeley bungalows to 1990s San Ramon tracts, and the rules change at the hills: inland Contra Costa reroofs often need a cool roof, and Oakland uses a self-certified permit. We explain both and connect you with an independent, licensed C-39 roofer for a free estimate.
Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.
- Licensed and insured
- Active C-39 license, checked on CSLB

Who does the work?
Licensed, insured and well reviewed. We only refer roofers we'd hire ourselves. Your request goes to an independent contractor focused on full roof replacements in the East Bay.
- Licensed and checked. An active California C-39 roofing license, with a contractor's bond and workers' compensation on file with the Contractors State License Board. We check the record before we send requests, and you can check it yourself.
- Replacement, start to finish. Inspection, tear-off down to the deck, sheathing repairs, underlayment and flashing, the new roof, cleanup, and the permit through final inspection.
- The materials Bay Area roofs need. Asphalt shingle, metal and low-slope systems, with Class A fire-rated assemblies where your zone calls for them.
- Warranties in writing. Your written contract should spell out the manufacturer's material warranty and the roofer's own workmanship warranty before any work starts.

Why is the East Bay replacing so many roofs?
Berkeley's median home was built in 1944 and Oakland's in 1953, among the oldest in any large California city. Over the hills, Concord (1970), Hayward (1972), Walnut Creek (1974) and Fremont (1979) filled in a generation later (ACS 2024 5-year).
Together, Alameda and Contra Costa counties hold more than 600,000 owner-occupied homes. Bayside houses face fog, trees and old overlays; inland tract roofs face heat, and in climate zone 12 the 2025 Energy Code adds a cool-roof rule to most reroofs.
| Area | Median year built | Owner-occupied homes |
|---|---|---|
| Alameda County | 1969 | 325,509 |
| Contra Costa County | 1978 | 281,819 |
| Berkeley | 1944 | 20,829 |
| Oakland | 1953 | 74,753 |
| Concord | 1970 | 28,473 |
| Hayward | 1972 | 28,799 |
| Walnut Creek | 1974 | 21,286 |
| Fremont | 1979 | 47,484 |

East Bay roof questions
Do I need a cool roof in Walnut Creek or Pleasanton?
Usually, for a steep-slope reroof replacing more than half the roof. Those cities are in climate zone 12, where the 2025 Energy Code requires one unless an exception applies.
Does Oakland issue reroof permits?
Oakland issues a self-certified Re-Roofing Certificate through its Online Permit Center instead. It's valid for 180 days and covers one structure.
Is my Berkeley hills home in a fire zone?
Check the 2025 state map for your address. Berkeley also adopted a Wildland-Urban Interface code chapter in 2025.
