Next-Level Resistance Against Fire & Water—
In a Single Layer
Introducing Our New Underlayment
Why complicate a tile roof system with multiple layers or an added cap sheet when there’s a simplified, tested solution?
Look no further than Eagle Anchor XFR, brought to you by Eagle Roofing Products in partnership with Polyglass®. This mechanically fastened underlayment delivers fire resistance and waterproofing with just a single layer.
Designed for concrete and clay tile roof systems, Eagle Anchor XFR combines a plastomeric modified bitumen top layer with a self-sealing SBS modified bottom layer. This dual-compound construction offers reliable protection against water intrusion while its patented Burn Shield Technology® delivers superior ember resistance—doing more than traditional cap sheets ever could.
Unlike cap sheets that aren’t waterproof and come with higher material and labor costs, Eagle Anchor XFR simplifies installation, reduces overall system weight, and cuts down on materials, making it a more efficient and environmentally conscious choice.
Backed by a tested and trusted system, Eagle Anchor XFR helps you meet Wildland Urban Interface (WUI), CalFire, and Class A Assembly fire rating requirements with one compliant layer. That means fewer steps, lower costs, and greater peace of mind.
Choose Eagle Anchor XFR to simplify your roof system – without compromising protection.
Eagle Anchor XFR is a product of Eagle Roofing Products “Secure Roof Components” line and
is currently only available in the Western United States and Western Canada.
