Where to Buy GAF

Thermoplastic polyolefin single-ply roofing membrane installed with heat-welded seams over low-slope roofs. Used on commercial buildings for its reflectivity and resistance to weathering, and applied in mechanically attached, adhered, or ballasted systems.

Heat-weldable thermoplastic single-ply roofing membrane made of polyvinyl chloride, offering chemical and fire resistance. Used on commercial low-slope roofs, particularly where grease or chemical exposure is a concern.

Modified bitumen membrane is a factory-fabricated asphalt-based roofing sheet reinforced with polyester or fiberglass, applied by torch, cold adhesive, hot asphalt, or self-adhesion. It is used in commercial construction on low-slope roofs, typically in multi-ply systems.

A low-slope roofing system constructed from alternating layers of bitumen and reinforcing ply felts, typically finished with a gravel or mineral surfacing. Used on commercial and industrial buildings to provide a durable, multi-ply waterproof membrane.

Metal roofing panels are formed steel or aluminum panels installed as standing-seam or exposed-fastener systems over roof structures. They are used on commercial, industrial, and institutional buildings for weather-resistant, long-span roofing.

Rigid polyisocyanurate foam board with facers, providing high thermal resistance per unit thickness for low-slope roofing. Installed over roof decks in commercial systems as continuous insulation and tapered assemblies for drainage.

Roof cover board is a rigid substrate installed over insulation to provide a durable surface for membrane attachment and resistance to impact, fire, and wind uplift. It is used in commercial low-slope roofing assemblies beneath single-ply and modified bitumen membranes.

Fluid-applied acrylic, silicone, or polyurethane coatings that provide a seamless protective and reflective layer over existing roof surfaces. Applied on commercial roofs for restoration, waterproofing, and reduced heat gain.

Sheet-metal or membrane components installed at roof transitions, penetrations, and edges to direct water away from joints. Used in commercial roofing to seal parapets, curbs, valleys, and terminations against leakage.

Sheet metal or aluminum channels and vertical conductors that collect and direct roof runoff away from the building. Used on commercial roofs and facades to manage stormwater at eaves and discharge to grade or drainage systems.

Screws, nails, and stress-distribution plates used to secure insulation, membrane, and cover boards to roof decks. Selected by deck type and pull-out resistance for mechanically attached commercial roofing systems.

Sheet material installed over the roof deck beneath the primary roof covering to provide a secondary water-resistant barrier. Used in commercial roofing as felt, synthetic, or self-adhered membrane products beneath shingles, tile, or metal panels.

Rigid polyisocyanurate foam board with facers, providing high thermal resistance per inch. Used as continuous insulation in commercial roofing assemblies and wall systems to meet energy performance requirements.

Ethylene propylene diene monomer single-ply rubber roofing membrane installed on low-slope commercial roofs in ballasted, mechanically fastened, or fully adhered systems. Valued for weathering resistance and long service life on flat and low-slope decks.
