GAF has come out with an extremely durable, high-performance TPO membrane roofing technology that is perfect for Oklahoma Roofing and for Oklahoma commercial roof jobs. This is so new, it is patent pending! You can read more about it here: http://www.gaf.com/Roofing/Commercial/Products/Single_Ply_Roofing/EverGuard_TPO_Single_Ply_Membranes
This is such an amazing product, that GAF is calling it the "next generation". They've named it EverGuard Extreme® TPO Roofing. Currently, they manufacture it in 50, 60, 70, and 80 mil.
It's mission: provide "next-generation performance against heat aging and UV degradation". *
Of course, you will also want to ask us about their highly rated, value-priced Smooth TPO Roofing System. They named it EverGuard® TPO, probably because they wanted to convey the idea that it would guard your building for a long time. It is puncture resistant, had strong seams, is cost-effective, and provides a high level of protection against weathering. This is a very reliable roofing system for Oklahoma commercial roofs. This TPO product is also well suited to the needs of Oklahoma commercial roofs.
