Founded in 1886 as a paint manufacturer, GAF Materials Corporation first entered the roofing materials market in the 1890's with its innovative “Ruberoid” ready-to-lay asphalt coating. Based out of Parsippany, New Jersey, GAF is now North America’s largest manufacturer of commercial and residential roofing, GAF enjoys roughly $3 billion in sales and a workforce of over 3,200 employees. An operating subsidiary of Standard Industries, GAF’s shingles have been rated #1 in quality by home builders for 10 out of the last 12 years. Offering 57 brands of products for a wide range of roofing applications, GAF building materials can be found in a quarter of all residential roofs in the United States.


GAF’s EverGuard® thermoplastic polyolefin (TPO) membrane provides a perfect blend of excellent performance and cost-effectiveness. EverGuard’s exceptional seam strength and puncture resistance, long-term performance under heat and UV exposure, and easy installation make it one of the most popular products on the market for low-slope roofing. Inherently flexible and naturally resistant to fungus, EverGuard TPO membranes are guaranteed for up to 30 years, and are available in a variety of thicknesses and application methods. With pigments specially selected to minimize fade, standard colors for EverGuard TPO membranes include White, Tan, Gray, Energy Gray, and Energy Tan. With 17 additional colors available, EverGuard TPO membranes can complement nearly any building design. Most color choices also include “Cool Color” technology, which helps reduce energy costs.


GAF’s EverGuard Extreme TPO single-ply roofing system has been shown by independent study to be the most durable TPO membrane on the market. Able to resist cracking under long-term heat and UV exposure, EverGuard Extreme exceeds all key ASTM standards for TPO membranes and is backed by an industry-best performance guarantee for up to 35 years. EverGuard Extreme’s heat-welded seams provide greater strength than taped membrane seams can help reduce energy costs, and the urban heat island effect. EverGuard Extreme can be mechanically attached for speed and cost-effectiveness, or installed with bonding adhesive for the smoothest appearance and superior wind uplift performance.


GAF’s best option for re-cover applications, the EverGuard and EverGuard Extreme Fleece-back TPO roofing system is also ideal for applications over abrasive surfaces such as concrete or granule-surfaced membranes, as no protective sheet is required. Compared with other TPO systems, Fleece-Back provides greater installation flexibility, as it can be mechanically attached, mopped in hot asphalt, or fully adhered using either conventional or low-rise foam adhesives. Along with all the benefits of other GAF TPO products, Fleece-back TPO offers enhanced hail resistance.


Because field fabrication of TPO accessories can be time consuming, costly, and unreliable, GAF provides a full line of prefabricated roofing accessories to complement its EverGuard and EverGuard Extreme TPO systems. Along with reducing installation expenses, GAF prefabricated TPO accessories can also have a significant effect on installation time. With products including textured walkway strips, joint patches, corner and tube wraps, vent and drain covers, and scuppers, the GAF line of TPO accessories is sure to provide solutions to nearly any problem faced during roofing installation.
