For performance and innovation in complete roofing systems, talk to GAF first.

Innovative system solutions to address your specific needs

GAF offers you a full line of commercial roofing system solutions, including single-ply membrane, asphaltic, coatings, and liquid-applied roofing, as well as waterproofing, polyiso insulation, and a complete line of innovative adhesives and accessories.

TPO Roofing

Thermoplastic polyolefin (TPO) is a single-ply roofing membrane that offers performance at a cost-effective price. Heat-welded seams provide superior strength. TPO's long-term heat, UV, and natural fungal resistance, plus flexibility without need for plasticizers also make TPO a reliable low-slope roofing system.

Liquid-Applied Roofing

Suitable for repairing and restoring roofing projects that don't require a tear-off. A liquid-applied roofing system is comprised of multiple components — including liquid-applied coatings and reinforced membranes, or any combination thereof — that cure together to form a fully adhered, seamless, and self-flashing membrane.

PVC Roofing

PVC (polyvinyl chloride) stands up to grease, oil and other chemicals compared to other material. Offers many of the same same performance advantages as TPO including heat-weldable seams, a highly reflective surface, and wider rolls.

Asphaltic Roofing

Asphaltic systems include Modified Bitumen (Mod-Bit) and Built-Up Roofing (BUR). Mod-Bit is made from asphalt modified with polymers or solvents to provide flexibility and strength. The BUR membrane consists of multiple plies of felts, fabrics, or mats with alternate layers of bitumen.

TPO performance that's proven to stand the test of time

A recent study of EverGuard® TPO roofs installed between 8 and 16 years ago found the all performed above ASTM standards for newly manufactured TPO. GAF analyzed membrane samples from roofs across the US and studied thickness over scrim, surface cracking, and the ability to repair aging TPO membranes.
