GAF Also produces EverGuard Extreme^® 60 mil TPO, EverGuard Extreme^® 70 mil TPO, and EverGuard Extreme^® 80 mil TPO. The 70 mil EverGuard Extreme® TPO is the perfect replacement for standard 80 mil TPO membranes, offering superior performance at an economical price. Whereas the 80 mil is their thickest, highest performing TPO roofing membrane, suitable for standard use or able to meet the most demanding situations. These are perfect for Oklahoma Commercial Roofs.

All of these products are manufactured with their new technology named EverGuard Extreme^® , which was developed to protect your Oklahoma commercial roof under extreme heat and UV situations.

As more and more companies install and mount solar panels directly on their commercial membrane roofs, new challenges are faced in roofing technology to meet the extreme heat build up which occurs on the roofing surfaces near the solar panels. Without enhanced UV and heat protection, your roofing membranes can fail early. Removing the BIPV and repairing failed roofing membrane is expensive.

EverGuard Extreme^® TPO was engineered to last longer with solar installations. EverGuard Extreme^® TPO uses proprietary stabilizers and UV absorbers to create a TPO roofing system for Oklahoma roofs that will withstand the most severe weathering and aging situations.
