TPO Roofing - EverGuard TPO 45 Membrane

EverGuard TPO 80 Mil Membrane

Why TPO?

  • Great Value — Superior performance at a cost-effective price

  • Excellent Seam Strength — Heat-welded seams provide greater seam strength to taped and other seams

  • Long-term Weathering — Excellent long-term heat and UV resistance

  • Energy Saving — Highly reflective and emissive white roof can help reduce energy costs and urban heat island effect

  • CREST Energy Savings Calculator — See your potential savings at

  • Versatile Application Method

Why GAF EverGuard® TPO?

  • Outperforms standard TPO in heat aging and UV tests—the best predictors of TPO performance
    - After accelerated heat aging at 275°F (135°C) for 105 days, EverGuard® TPO showed no cracking—while every one of the competitors’ samples had failed!
    - UV testing—Greater than 2.5 times the industry standard (ASTM D6878 weather resistance test

  • Guarantees are available up to 30 years when using EverGuard® TPO 80 mil Membrane.*

  • Easier to install due to:
    - Large welding window
    - Most complete line of accessories
    - 10' (3.05 m) wide sheets


EverGuard® TPO 80 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 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%.


GAF's sustainability credentials include:

  • NSF/ANSI 347 — Providing architects and contractors with a certified sustainable option for single-ply roofing membranes

  • UL Landfill Waste Diversion Validation — Zero Waste to Landfill (Mt. Vernon TPO Plant)

  • HPDs — Only single-ply roofing manufacturer that publishes Health Product Declarations (HPDs) for transparent reporting and LEED® v4 compliance

  • EPDs — Publishes Environmental Product Declarations (EPDs) for Single-Ply Roofing Membranes
