Polyglass USA has become the first manufacturer to receive CAL FIRE BML Class A approval for a complete low-slope roofing system. This certification allows property owners in California to meet stringent building code requirements in high-risk zones.
Why it matters
This approval addresses the state's escalating wildfire seasons and strict building regulations within Wildland-Urban Interface areas. Property owners installing the systems may now qualify for insurance discounts under the Safer from Wildfires program.
The roofing systems are certified for use with a minimum deck requirement of C-15/32 and a roof incline specification of 2:12. These components were evaluated under standardized ASTM E108 and UL 790 testing protocols.
