Which Lafayette is this?
Lafayette, California, along with Orinda and Moraga, the three towns known together as Lamorinda, just east of the Oakland and Berkeley hills in Contra Costa County. Not Lafayette, Louisiana, Indiana or Colorado. Lafayette's and Orinda's median homes were both built in 1960 (ACS 2024 5-year), so many houses are on their second or third roof, and the hills and oaks around them shape every job.
How do I check a Lamorinda roofer's license?
Search the business on the CSLB license lookup. For a reroof you want an active license with the C-39 Roofing classification (CSLB: C-39), a bond on file and, if the company has employees, a workers' compensation policy. The name on your estimate should match the CSLB record exactly.
How do the fire and cool-roof rules combine?
Lamorinda's ZIP codes are in climate zone 12 (CEC), so a reroof replacing more than half the roof generally needs a rated cool-roof product (CEC guide). Many hillside streets are also in or near mapped fire hazard zones (CAL FIRE map), and in a very high zone the roof must be Class A (HSC 13132.7). The right product satisfies both; a roofer who only mentions one is missing half the brief.
Which building department?
- Lafayette: City of Lafayette Building Division
- Orinda: City of Orinda
- Moraga: Town of Moraga Building Division
Canyon and some edges are unincorporated and go to Contra Costa County. Long, steep driveways and tight streets mean staging matters, so ask where materials and the bin will go.
