Attention California residents and homeowners in high fire danger areas

Whether you're building a new home in California or re-roofing your current home in a high fire danger area, it is very important to know about the Wildland-Urban Interface (WUI) Code.

A wildland-urban interface (WUI) code is specifically designed to mitigate the risks from wildfire to life and property. The standards within a WUI code will vary according to the scope that a community is willing to adopt and enforce.

The United States Forest Service defines the Wildland-Urban Interface (WUI) as the place where homes and wildlands meet or intermingle. WUI is designed to reduce the risk of wildfire spread from forest areas to human life and property. 

WUI recognizes the growing amount of wildfires in the United States. The WUI code includes the identification and evaluation of building product materials that resist flame spread. The necessary requirement of WUI is that the exterior of a structure resistant the entry of embers, fire radiation, and be ignition resistant during a wildfire.

Sparks and ignited debris can be lifted and carried by convection currents up to a half-mile from a fire. If conditions are windy ignited debris can travel even further.

CeDUR roofs are approved by WUI. By choosing CeDUR you will have a fire resistant roof that self-extinguishes flame spread. CeDUR is the only roofing material that is fire resistant, self-extinguishes flame spread and does not require the use of a special fire resistant underlayment during installation.

WUI is not a California state wide code. Some California counties provide WUI specific information. You can visit the State Fire Marshall's Building Materials Listing to see if certain product are approved.
