Two climates, two clocks
The Energy Commission puts Oakland, Berkeley, Hayward and Fremont in climate zone 3 and Walnut Creek, Concord, Pleasanton, Livermore and San Ramon in climate zone 12 (CEC climate zones). InterNACHI notes that hot climates drastically reduce asphalt shingle life (InterNACHI).
| Roofing material | Estimated life (years) |
|---|---|
| Asphalt shingles (3-tab) | 20 |
| Asphalt shingles (architectural) | 30 |
| Wood shakes or shingles | 25 |
| Metal | 40 to 80 |
| Clay or concrete tile | 100+ |
| Slate | 60 to 150 |
| Built-up roofing (flat) | 30 |
| Modified bitumen (flat) | 20 |
| TPO (flat) | 7 to 20 |
| EPDM rubber (flat) | 15 to 25 |
How old is my East Bay roof likely to be?
A 1953 Oakland house has probably had two or three roofs. A 1979 Fremont tract home may be on its second, installed in the late 1990s or 2000s, which puts it near the end of a typical shingle's life now.
What adds years?
- Keep valleys and gutters clear of oak and eucalyptus litter.
- Make sure the attic is ventilated; trapped heat ages shingles from below.
- Inland, choose a rated cool-roof product (often required anyway) to cut heat on the roof surface.
Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.

Do roofs wear out faster in Concord than Oakland?
Heat is harder on shingles than mild weather, so inland roofs often age faster, though shade and moisture cause their own problems bayside.
What climate zone is my city?
Bayside cities such as Oakland, Berkeley and Fremont are zone 3; inland cities such as Walnut Creek and Pleasanton are zone 12.
How long does a tile roof last?
InterNACHI lists clay and concrete tile at 100-plus years, though underlayment needs replacing much sooner.
