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.

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
What is going on here? No, this roof does not have measles, it has a problem with thermal bridging through the roof fasteners holding its components in place, and this problem is not one to be ignored.
Cold storage facilities face unique challenges when it comes to maintaining optimal interior temperatures. One crucial aspect in ensuring efficient temperature control is creating an airtight roof system which can help prevent cooled interior air from escaping, warmer exterior air from entering, reduce thermal loss and condensation potential, all while promoting energy efficiency and prolonging the life of the roof system and building.
Buildings are designed to keep the outside weather out and the inside space conditioned as the occupants desire. A building's enclosure or envelope is made up of multiple layers of materials with the goal of stopping the uncontrolled movement of water, air, heat, and moisture vapor.
Companies, organizations, and firms working in the building, construction, and design space have a unique opportunity and responsibility. Collectively, we are contributing to nearly 40% of energy-related carbon emissions worldwide. While the goals, commitments, pledges, and promises around these challenges are a step in the right direction, no one entity alone will make major improvements to this daunting issue.
