Fire Hardening Roofs:
The New Benchmark for HOA Insurability
As Southern California approaches the one-year mark since the devastating Pacifi c Palisades, Altadena, and Malibu wildfi res, the urgency for fi re preparedness has never been more critical. Those fi res destroyed homes, scarred neighborhoods, and left insurance carriers reevaluating risk in every hillside community.
Today, HOAs throughout California are feeling the aftershocks. In communities located in wildfi re-prone areas, we’re hearing horror stories of insurance premiums rising by 200% to 1,000%. In some cases, carriers have pulled out completely. The message from insurance companies is clear: lower your fi re risk or it will cost you.
Understanding WUI and HFSZ: Where Your Community Stands
California’s Wildland Urban Interface (WUI) identifi es areas where neighborhoods and wildlands meet — the zones most vulnerable to ember-driven wildfi res. High Fire Severity Zone (HFSZ) maps created by CAL FIRE classify areas as Moderate, High, or Very High risk. Homes and HOAs located within these zones must comply with Chapter 7A of the California Building Code, which establishes strict construction standards designed to slow or stop ember intrusion, the leading cause of home loss during wildfi res.
When Compliance Applies
Existing communities aren’t required to adhere to the new standards unless required by a municipality in conjunction with obtaining a building permit for a construction project. Re-roof projects, new siding, or large-scale exterior repairs will typically require permits.
16 January | Febuary 2026 That means:
• Re-roof projects or large exterior repairs must use full Class A fi re-rated assemblies and ember-resistant ventilation.
• Annual roof maintenance and leak repairs: Usually exempt, though best practice is to fi re-harden where possible.
• New construction or additions: Automatically subject to Chapter 7A fi re-hardening requirements.
While your HOA may be “grandfathered in,” the next major re-roof may require full compliance.
Fire-Ready Roofi ng: What It Takes to Meet the Standard
So, you’ve confi rmed that your community is located in a WUI and/ or a HFSZ and you’re planning a re-roof. This is where compliance moves from code to application. Your new roofi ng system must meet a Class A fi re-resistant assembly, not just Class A surface material. The entire system, top to bottom, must be tested and approved under ASTM E108 or UL 790 as a complete assembly.
