Eagle Anchor XFR: Fire-resistant protection simplified

By The Coffee Shops®. 

Eagle Roofing Products has partnered with Polyglass® to bring you fire resistance and waterproofing in one single layer. 

As building codes evolve and wildfire risks increase, roofing systems must deliver more than just basic weather protection. Eagle Anchor XFR answers that demand with a high-performance underlayment that combines fire resistance and waterproofing into a single, streamlined solution, designed specifically for modern tile roof systems.  

Engineered for use beneath concrete and clay tiles, it eliminates the need for traditional multi-layer assemblies by delivering both water protection and fire resistance in one layer. This simplifies installation while reducing labor, material usage and overall system weight. 

Manufactured by Polyglass® and brought to you in a partnership with Eagle Roofing Products, the core of the product is a dual-compound construction: a durable plastomeric modified bitumen top layer paired with a self-sealing SBS-modified bottom layer. This design allows the membrane to tightly seal around fasteners, helping prevent water intrusion while maintaining long-term durability.   

What truly sets Eagle Anchor XFR apart is Polyglass's Burn Shield Technology®, which provides advanced resistance to wind-driven embers, one of the leading causes of roof ignition during wildfires. Combined with a fiberglass reinforcement layer, the system achieves a Class A fire rating and meets strict requirements for Wildland Urban Interface (WUI) zones, including CalFire compliance.   

Beyond fire performance, the underlayment is built for real-world jobsite conditions. Its mineral-surfaced top layer improves slip resistance for safer installation, while its robust construction allows for up to 180 days of UV exposure before tile installation, offering flexibility in project scheduling.   

Eagle Anchor XFR also delivers clear economic advantages. By replacing the need for separate underlayment and cap sheet systems, it reduces installation steps and material costs without sacrificing performance. The result is a more efficient, cost-effective roofing system that simplifies compliance with high fire risk zone code requirements.   

Eagle Anchor XFR represents a smarter approach to tile roofing underlayment, combining fire resistance, water protection and installation efficiency into one integrated solution. For contractors and builders working in high-risk or code-driven environments, it offers a reliable way to simplify systems while enhancing overall roof performance.
