High-Performance Roofing Systems

The FORTIFIED Roof™ standard developed by the Insurance Institute for Business & Home Safety (IBHS) sets the national benchmark for fortified roofing, helping homes and buildings better withstand extreme weather events such as high winds, hail, and heavy rainfall.

This compliance represents a powerful collaboration between IBHS’s building science expertise and Polyglass’ advanced roofing technologies. It reflects a shared commitment to resilient, performance-based construction practices that exceed traditional code requirements.
