Roofing Estimating for California Contractors

California's Title 24 cool-roof requirements, wildfire-interface zones requiring Class A assemblies, and coastal fog exposure make roofing specifications here among the most prescriptive in the country. California requires a C-39 Roofing Contractor license. Title 24 compliance documentation required at permit submittal for all new and re-roof projects.

California-Specific Scope Considerations

  • › Title 24 cool-roof SRI requirements for low-slope roofs in CEC climate zones
