Why GAF EverGuard Extreme® TPO

  • Get the performance beyond a 60 mil TPO in a 50 mil product.
  • Best performing TPO in heat aging and UV tests–the best predictors of TPO performance.
    • After accelerated heat aging at 275°F (135°C) for 190 days, EverGuard Extreme® TPO showed no cracking — while every one of the competitors’ samples had failed!
    • UV testing—greater than 4.6 times the industry standard (ASTM D6878 weather resistance test)
  • Guarantees are available up to 25 years when using EverGuard Extreme® TPO 50 mil Membrane*
  • High 3-year aged reflectance of 0.72 can help reduce energy costs
  • Easier to install due to:
    • Large welding window
    • Most complete line of accessories
    • 10’ (3.05 m) wide sheets


EverGuard Extreme® 50 mil Membrane is suitable for all types of single-ply systems:

  • Mechanically Attached Application - for a quick and cost-effective system that can be installed practically year-round.
  • RhinoBond® Application - can be applied without using adhesives and installed practically year-round. Qualifies for the same guarantee length as an adhered system.*
  • Adhered Application - can be installed with EverGuard® 1121 Bonding Adhesive (solvent-based), EverGuard® Low VOC TPO Bonding Adhesive, or EverGuard® WB181 Bonding Adhesive (water-based) for the smoothest appearance. Provides superior wind uplift performance.


Field fabrication of TPO accessories is time-consuming, costly, and inconsistent, and can lead to unreliable details that compromise a watertight roofing system. EverGuard® TPO prefabricated accessories deliver consistent quality and eliminate the worry and problems often associated with field fabrication. They can also boost productivity up to 200%,** while reducing installed cost by up to 12%.
