If you live in the Oakland Hills, Lamorinda, Mission San Jose, or other designated fire zones in the Bay Area, your roof must meet specific fire safety requirements. These regulations exist to protect homes and communities from wildfire, and understanding them is essential before any roofing project.
Understanding Fire Zones
California designates areas based on wildfire risk:
Very High Fire Hazard Severity Zones (VHFHSZ): The highest risk areas, often in hills and canyons with dense vegetation. These areas have the strictest requirements.
High Fire Hazard Severity Zones: Elevated risk areas with significant requirements.
Moderate Fire Hazard Severity Zones: Lower risk but still subject to fire-safe building codes.
Many Bay Area neighborhoods fall into high or very high categories, including:
- Oakland Hills and Montclair
- Lamorinda (Lafayette, Moraga, Orinda)
- Berkeley Hills
- Shell Ridge and Lakewood (Walnut Creek)
- Mission San Jose (Fremont)
- Saratoga and Los Gatos foothills
Class A Roofing Requirements
In fire zones, roofing materials must be Class A fire rated—the highest rating available. Class A materials can withstand severe fire exposure without igniting.
Approved Class A Materials:
Asphalt Shingles: Most modern architectural shingles are Class A rated. Look for the UL or ASTM fire rating on product specifications.
Concrete and Clay Tile: Naturally fire-resistant and commonly Class A rated. Popular in Mediterranean-style homes throughout the Bay Area.
Metal Roofing: Inherently non-combustible and typically Class A when installed over appropriate underlayment.
Slate: Natural stone is non-combustible and Class A rated.
Composite Materials: Many synthetic products are designed for Class A performance.
Materials to Avoid:
Wood Shake/Shingles: Not permitted in fire zones unless specially treated, and even then, may not be allowed in some jurisdictions.
Certain Rolled Roofing: Some economy products don’t meet Class A standards.
Additional Fire Zone Requirements
Beyond the roofing material itself, fire zones often require:
Ember-Resistant Vents
Attic and roof vents must prevent embers from entering. Mesh screens with 1/8” or smaller openings are typically required.
Eave Protection
Enclosed eaves or fire-resistant soffits prevent flames and embers from entering the attic space.
Gutters
Metal gutters are preferred over vinyl. Some jurisdictions require gutter guards to prevent debris accumulation.
Defensible Space
While not a roofing requirement, maintaining clearance around your home affects your overall fire safety—and may affect insurance rates.
Insurance Considerations
Many insurance companies now require:
- Proof of Class A roofing
- Documentation of fire-resistant features
- Defensible space compliance
A new fire-compliant roof can:
- Reduce insurance premiums
- Make your home insurable when others aren’t
- Provide documentation for FAIR Plan alternatives
If you’re unsure about your roof’s fire rating, a professional roof inspection can assess compliance and identify any issues.
Permit Requirements
Fire zone roofing projects require permits and inspections. The permitting process typically includes:
- Plan Review: Verification that proposed materials meet fire codes
- Material Approval: Documentation of Class A rating
- Installation Inspection: Verification of proper installation
- Final Approval: Sign-off that work meets all requirements
Our contractors handle permit applications and know the specific requirements for each Bay Area jurisdiction.
Cost Considerations
Fire-compliant roofing may cost slightly more due to:
- Higher-quality materials
- Additional installation requirements
- Permit and inspection fees
However, the investment pays off through:
- Insurance savings
- Home protection
- Resale value
- Peace of mind

- Know local code requirements
- Can provide Class A material documentation
