Quality You Can Trust
From North America’s Largest
Roofing Manufacturer

It doesn’t matter whether you’re located in Camden County, nestled right up against the Delaware River, or somewhere more rural, like the outskirts of Cape May County. A commercial roof requires materials that are constructed to stand up against the elements. With South Jersey’s four seasons and unpredictable weather patterns, you want to make sure your commercial roofing system is ready for whatever happens.
That’s why GAF commercial roofing materials are considered top-of-the-line and also the favored materials here at RGB Construction.

TPO and PVC Single-Ply Membranes
Both membranes are single-ply and produced in large sheets. TPO and PVC alike a mechanically fastened to a roof by either adhering or ballasting over insulation.
EverGuard® TPO, also known as Thermoplastic Polyolefin is durable, heat-reflective (comes in white), and highly energy-efficient.
EverGuard® PVC, or Polyvinyl Chloride, is known for chemical and grease resistance, making it ideal for restaurants.
Both provide excellent energy savings in summer and a faster installation than built-up systems. TPO and PVC also have fewer seams when compared to older membranes, making them more watertight and resilient.
Asphalt Roof Systems
Asphalt roofing systems consist of built-up roofing (BUR) and Modified Bitumen (mod-bit). These systems have been around for a long time and are still popular in commercial settings for their protective abilities. Asphalt roofs have multiple layers to provide excellent waterproofing and also had foot traffic and rooftop equipment better than membranes.
What to know:
- BUR has layers or piles of roofing felt alternating between asphalt. The final layer is an EnergyCap™ cap sheet or gravel.
- Mod-Bit is rubber (SBS) or plastic (APP) polymers in it, allowing for greater flexibility and resistance to cracking.
Roof Coating and Restoration Solutions
Roof coatings are liquid-applied systems such as acrylic, silicone, or formulas like HydroStop® that “seal” existing roof surfaces to extend service life and durability. These liquid-applied systems add a seamless, waterproof layer, dealing the need for tear-off and replacement. It’s quick to apply, seals small defects, and comes at a lower cost than replacement.
Insulation and Cover Boards
Most commercial roofs will have rigid insulation (often polyisocyanurate) installed under the membrane and over the roof deck to increase R-value and reduce HVAC loads, where present. At RGB Construction, we recommend cover boards and insulation for buildings with heavy rooftop equipment loads or the need for higher insulation values.
Commercial Roofing Accessories and Flashing
Accessories include fasteners, plates, sealants and adhesives, and perimeter edge metals. When installing your GAF commercial roof, our team uses only accessories provided by GAF to ensure your warranty stays intact. Everything is installed according to manufacturer guidelines and local code.
