Roof replacement
in the North Bay
Across Sonoma, Napa and Marin, a new roof is a fire decision as much as a weather one. We explain Permit Sonoma's Class A rule and pre-inspection, Napa County's online permits and what a reroof costs, then connect you with an independent, licensed C-39 roofer for a free written estimate.
Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.

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 North 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.

What makes North Bay roof replacement different?
Wildfire. After the fires of recent years, roofs across Sonoma and Napa come up often in insurance renewals and home sales. In unincorporated Sonoma County, re-roofing more than half a roof requires a Class A assembly (Permit Sonoma B-07).
Age matters too. Sonoma County's median home dates to 1979, Napa County's to 1976 and Marin's to 1967. In Santa Rosa (1980) and Petaluma (1979), many 1990s replacement roofs are reaching the end of their life now (ACS 2024 5-year).
| Area | Median year built | Owner-occupied homes |
|---|---|---|
| Marin County | 1967 | 66,616 |
| Sonoma County | 1979 | 119,598 |
| Napa County | 1976 | 31,555 |
| San Rafael | 1968 | 12,140 |
| Novato | 1975 | 13,258 |
| Petaluma | 1979 | 15,643 |
| Santa Rosa | 1980 | 38,759 |
| Napa | 1974 | 17,602 |

North Bay roof questions
Does Permit Sonoma inspect before the new roof goes on?
Yes. Permit Sonoma's residential reroofing process includes a pre-inspection and a final inspection, so build the pre-inspection into the schedule.
Do I need a cool roof in Santa Rosa or Napa?
No prescriptive requirement. Santa Rosa, Petaluma and Napa are in climate zone 2, outside the zones where the 2025 Energy Code requires a cool roof on a home reroof.
Is there a local program to finance a roof?
Sonoma County runs the Sonoma County Energy Independence Program, a PACE program on the state's enrolled list. PACE covers energy and water efficiency improvements, so ask the program whether your roof qualifies.
