This is a great choice for everyday type roofing needs for your TPO roof here in Oklahoma. The 50 mil EverGuard Extreme® TPO can cost-effectively replace standard 60 mil TPO roofing.
This roof really meets the challenges of heat build up on flat or low slope roofing systems on Oklahoma Commercial roofs. The 50 mil EverGuard Extreme® TPO has advanced Heat & UV protection.
This is also the roofing system you'll want to consider if you have solar panels mounted directly onto your white roofing membrane. Without enhanced UV and heat protection systems, your commercial TPO roof membranes can fail prematurely.
EverGuard Extreme® TPO was engineered to protect premature failure in TPO roofs, due to high heat and solar loading.
While TPO single-ply roofing membranes have an excellent history in protecting Oklahoma commercial roofs, they are subject to damage by extreme heat, sunlight and UV. According to GAF, solar panels can create areas of high temperatures up to 190 degrees F on roofing areas immediately near them. See http://www.gaf.com/Roofing/Commercial/Products/Single_Ply_Roofing/EverGuard_TPO_Single_Ply_Membranes/EverGuard_Extreme_50 for a discussion about this.
GAF's solution is the EverGuard Extreme®: TPO formulated for the most severe weather and temperature commercial roofing system needs.
