About GAF Headquarters

As a world-leading manufacturer of roof components, GAF demands a roofing solution for its own headquarters that sets the standard in sustainability. The 377,000 sq. ft., state-of-the-art facility is the first building in the world to be awarded a LEED® Resilient Design Pilot credit from the U.S. Green Building Council (USGBC).

The Challenge

GAF moved its corporate headquarters to Parsippany, NJ., in 2015, after the historic company spent 40 years occupying an 11-building campus in Wayne, N.J. GAF was determined to lead by example in environmental sustainability.

The Solution

The roof system employs RUBEROID® HW 25 Smooth Membrane as a vapor retarder, EnergyGuard Polyiso Insulation, and EnergyGuard HD Cover Board. It also includes GAF’s best-performing single-ply membrane, EverGuard Extreme® Fleece-back TPO Membrane.

GAF 2-Part Roofing Adhesive was used to fully adhere EverGuard Extreme® Fleece-back TPO to provide superior wind uplift performance. When using EverGuard Extreme® Fleece-back TPO Membrane with GAF 2-Part Roofing Adhesive, the fleece on the back of the membrane provides an added cushioning layer, which is especially important for hail-prone areas.

LEED Certification

GAF headquarters was the first building in the world to be awarded a LEED® Resilient Design Pilot credit from the U.S. Green Building Council. To achieve this designation, also known as the IPpc98 credit, building owners must assess and successfully plan for a wide range of natural disasters such as flooding, tornados, high winds, and earthquakes. There are several aspects of the GAF building design that led to this designation, including flood preparation and backup capabilities that allow GAF to continue operations and customer service in the face of disaster and long-term outages.

“I take great pride in showing our installation of the GAF membrane to industry professionals…. In addition, with the emergence of new building practices, for instance RhinoBond®, we are able to share through our publications the value that peripheral innovative products bring to
the industry.”
