In 2008, a major food and beverage distribution center in Allentown, Pa., began negotiations with Sika Sarnafil, Canton, Mass., to re-cover the center's 17-year-old, 1.1 million-square-foot PVC roof system with a new Sika Sarnafil PVC membrane. Sika Sarnafil asked one of its Elite Applicators, Nations Roof LLC, Yonkers, N.Y., to install the new membrane.
"We learned about the project from our Sika Sarnafil regional manager," says Michael Johannes, Nations Roof's president. "We were asked to install a new Sika Sarnafil membrane over the existing roof and reflash 850 skylights.
"The building owner proactively budgeted for the project in advance," Johannes continues. "A lot of building owners wait until the end of a roof system's life—when the roof is already saturated—to perform repairs. Before the roof became a repair mess, its owner decided to have reroofing work performed so the roof system wouldn't have to be completely torn off."
