A crew of about a dozen people installed about 6,000 feet of new roofing per day, using about 38 rolls of the GenFlex 0.060 EPDM after installing GenFlex polyiso insulation underneath. Ezold said the major challenge of this project was getting the ballast removed without the rest of the roof blowing off in the middle of the job.



Losing a few pounds over the summer would make just about anyone … or anything … feel pretty good.

According to one contractor in the Boston area, the same goes for light industrial, commercial site roofs. In fact, one particular roof in Hudson, Mass., literally lost 100 tons of ballast over its 58,000 square feet of surface before it was reroofed.

“It sounds simple, but a job like that just makes the building feel better for the tenants,” said Dick Ezold of D&R Roofing of Douglas, Mass. “It relaxes the building itself.”

Besides a roof that no longer leaks, D&R improved the R-Value of the building by about six points by using a fully adhered GenFlex EPDM roofing system. Fully adhered systems install with a continuous, even surface, have no mechanical penetration of the membrane and add minimal weight to the deck.

Another benefit to the fully adhered roof is less liability for crews walking on the roof to inspect or repair HVAC units and other equipment on the roof.

Ezold said the major challenge of this project was getting the ballast removed without the rest of the roof blowing off in the middle of the job. Working nearly simultaneously with the vacuum crew and using the new materials as they were delivered helped keep the old system in place until they could get the new roof installed.

GenFlex EPDM systems have a performance history of more than 20 years and can be warranted for up to 20 years depending on the system design. EPDM comes 45 mil (1.1mm) or 60 mil (1.5mm ) thick and is available in rolls up to 50 feet (15.2m) wide by 250 feet (76.2m) long. It is ideal for either new roofs or for roofing over a variety of common roof deck types and insulation materials. Installation systems include ballasted, fully adhered and a number of mechanically attached alternatives.

A high-performance membrane, EPDM is resistant to tears, impacts, punctures and normal roof traffic. Normal structural movement has limited effect on its integrity. This membrane provides excellent resistance to ozone and ultraviolet light exposure.

EPDM is part of a complete GenFlex roofing system, including GenFlex polyiso insulation or tapered polyiso insulation and components such as roofing tapes, bonding adhesive, sealants, flashing and applicable rooftop accessories.
