What Does a Wildfire Defense System Cost?
Every property is different, and that is exactly why FireRoofs does not publish a fixed price list. Roof area and pitch, the number of eaves and overhangs, zone count, water pressure and supply source, terrain access, and whether foam injection or supplemental water storage is included all influence system design and cost.
FireRoofs requires a physical site evaluation before providing a proposal. That evaluation includes water pressure testing, a roof and eave inspection, and a complete Zone Zero walkthrough. It is how we protect homeowners from undersized systems that leave gaps or over-specified systems that waste money.
The evaluation is free. No obligation. No deposit.

ROI and Insurance Context
Home values in WUI communities like Saratoga and Portola Valley typically range from $3M to $8M or more for luxury properties. The California FAIR Plan caps dwelling coverage at $3M. Rebuilding a 3,000 to 5,000 square foot custom home in the WUI can cost $5M to $15M or more. That gap between the FAIR Plan cap and actual rebuilding cost is uninsured.
Private insurers who still write policies in the WUI increasingly require active wildfire mitigation. A documented exterior defense system may support policy renewals or premium discussions with your carrier. FireRoofs provides complete installation documentation, system specifications, and zone coverage maps that can be submitted to your insurance company.
The cost of a wildfire defense system is a fraction of the uninsured rebuilding exposure for most Bay Area WUI homes. Whether you are protecting a $4M estate in Los Gatos or a $10M property in Atherton, the investment in active structural defense addresses a risk that insurance alone no longer covers.
