Anti-Incendiary Roof Layering

Our anti-incendiary roofing systems deliver passive wildfire defense through Class A-rated, polymer-based underlayments and coatings. These self-adhering, fiberglass-reinforced membranes are designed to eliminate vulnerable gaps, block airborne embers, and resist direct flame exposure. Every assembly we install is tested to meet or exceed ASTM E108 and UL 790 standards, ensuring code compliance and maximum protection in fire-prone zones.


Already have a new roof? We can apply a fire-rated silicone or PVC coating directly over your existing system—no tear-off required. This seamless barrier improves resistance to heat, UV, and ember ignition, while preserving your current roof’s integrity and appearance. It’s an ideal upgrade for homes in expanding wildfire zones, or for anyone looking to harden their structure without starting from scratch.

These materials form the foundation of a multi-layer fire-resistant system, compatible with metal, tile, or membrane roofs—and especially effective when combined with enclosed eaves, CAL FIRE-rated vents, and noncombustible gutters. While traditional asphalt systems can fail in minutes under ember attack, our assemblies are engineered to withstand over an hour of sustained flame, buying time for response and saving structures that might otherwise be lost.


Research confirms that Class A fire-rated roofing assemblies are essential for wildfire resilience in Wildland Urban Interface (WUI) areas. Agencies such as Cal Fire and the NFPA have identified ember intrusion as one of the leading causes of structural loss during wildfires—losses that can be mitigated by systems designed to interrupt ignition pathways at the roof level.

Coldwater Cool Roofing integrates only top-tier fire-rated underlayments, including products like Owens Corning’s Titanium® FR and similar membrane technologies. Our installations are aligned with state code and CAL FIRE structure hardening standards, giving clients confidence in both compliance and performance.
