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. 

Insulation and Cover Boards

EnergyGuard Polyiso Insulation offers a complete lineup of products to meet most low-slope commercial roofing insulation needs. It provides exceptional thermal performance at an economical price.

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.

LATEST FROM GAF ROOF VIEWS
Introduction Wind design of roof systems can be confusing from an engineering perspective. Wind design can also be confusing because the International Building Code (IBC) provides specific requirements, but so does Factory Mutual (FM). If FM is specified, do the IBC requirements need to be followed? What is the wind-design strategy for FM-insured and non-FM-insured buildings? This blog will discuss the following:
The International Energy Conservation Code (IECC) is a building code created by the International Code Council in 2000. It is a model code adopted by many states and local governments in the United States for the establishment of minimum design and construction requirements for energy efficiency.
Low slope roof penetrations can be a source of problems if not done correctly. Pipe, vent, and conduit penetrations through low slope roof assemblies can cause problems for an otherwise tight membrane, insulation, and deck design. With many intermediate layers in roof assemblies, such as a vapor retarder and cover board, there are opportunities for things not to be done correctly somewhere in the assembly. It gets even more complex when we consider that in order to use a vapor retarder, there might be an additional cementitious board above a steel deck.
