Building Overview
• GAF recently moved from their Wayne, NJ, offices to a new corporate headquarters at
1 Campus Drive in Parsippany, NJ. The 128-year-old company spent approximately
40 years occupying 11 buildings on the Wayne campus and made the move in early
2015 to consolidate operations into a 377,000-square-foot-state-of-the-art facility on a
40-acre campus.
Challenge
• The existing building that GAF was moving into had a ballasted EPDM roof with XPS and
EPS insulation. While the existing roof was not leaking, it was determined that due to
the use of the XPS and EPS insulation, the roof design was not as energy efficient as
GAF would like to have. In addition, the use of taped EPDM seams meant the increased
possibility of leaking as compared to a heat weldable seam. It was determined that the
more efficient EnergyGuard™ ISO and heat weldable EverGuard Extreme® TPO replace
the existing roof.
Materials Used
• RUBEROID® HW 25 Smooth Membrane
• EnergyGuard™ Polyiso Insulation
• EnergyGuard™ HD Cover Board
• EverGuard Extreme® Fleece-back TPO 60 mil
• GAF 2-Part Roofing Adhesive
• EverGuard Extreme® TPO Accessories
Solution
• Since GAF is a roofing manufacturer, they wanted the best-performing commercial roof
available. It includes GAF’s RUBEROID® HW 25 Smooth Membrane as a vapor
retarder, EnergyGuard™ Polyiso Insulation (for exceptionally high insulation value),
and EnergyGuard™ HD Cover Board (which offers the highest R-value per inch thickness
in the industry and superior impact resistance).
• It also includes GAF’s best-performing single-ply membrane, EverGuard
Extreme® Fleece-back TPO Membrane. GAF is particularly proud of how far EverGuard
Extreme® Fleece-back TPO Membrane outperforms competitive TPO membranes
(based on heat-aging tests), and backs it with the industry’s longest commercial roofing
guarantee.
• 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 (compared to
EverGuard Extreme® Smooth TPO Membrane), the fleece on the back of the membrane
provides an added cushioning layer, especially important for hail-prone areas.
• Also, EverGuard Extreme® TPO Accessories with EverGuard Extreme® Fleece-back TPO
Membrane helps save labor (versus field fabrication) — and provides an overall
cleaner-looking roof.
Key Fact
• As part of GAF’s commitment to sustainable roofing choices, GAF recycled the old EPS
and XPS insulation, the worn-out EPDM membrane, and even removed the ballast
during the reroof. This material will be repurposed in many ways – for crumb rubber,
warehouse insulation, and other applications.
