The Problem These homeowners wanted to transform a flat roof into useable outdoor living space. The torch on flat roof they had was unattractive and retained too much heat in the summertime, super-heating the structure and leading to higher air conditioning costs. With no guard rails in place, it was not useable outdoor leisure space. They also discovered that torch on flat roofing lifts and bubbles from trapped moisture, causing leaks. Expansion and contraction through the seasons caused cracks which resulted in immediate waterproofing failure. This waterproofing failure allowed moisture penetration, and rot would develop quickly, so they gave Duradek a call.   The Duradek Solution The failed torch on product was removed and fresh, untreated ¾" plywood was laid at the recommended slope to accept the Duradek Cork Graphite vinyl membrane. Duradek’s professional installation treats all interior perimeters including the door threshold, so there is added confidence that the building envelope is completely protected. Since Duradek is both a classified roofing membrane and a pedestrian traffic surface, they economically turned their flat roof into a useable deck by including new Durarail Aluminum Picket Railings to match new trim. Now, previously wasted space and a point of waterproof vulnerability provides safe, protected and useable outdoor living space.
