PVC
Polyvinyl chloride (PVC) roofing systems were first installed in Europe in the 1960’s and arrived in the US in the 1970’s. Its use on low-slope roofs has increased dramatically in the past decade. Our PVC roofing system is a single-ply membrane that consists of two layers of PVC material with a polyester reinforcement scrim between the layers. In the past 20 years, the reinforcement of the material with the scrim is what has made the system we use the most durable PVC system available. PVC roofs are welded together at the seams by using a hot-air welding gun. This creates a permanent bond between two separate sheets of roofing membrane.
One of the biggest advantages of the Durolast PVC roof we use is that it is custom fit to your roof at the factory with 80-85% fewer seam welds required on site. This ensures minimal opportunities for water to find a seam to leak through. PVC roofs are most often mechanically attached by screwing down plates into the deck. They are extremely lightweight and durable, even in high winds. They also do not break down when foreign chemicals like fats and oils are discharged onto the roof. Another huge advantage of a white PVC system is its reflectivity. This type of system reflects over 90% of the sun’s energy away from the roof and is often referred to as a “cool roof.” This results in less energy being absorbed, less heat buildup, and lower energy bills. See GREEN SOLUTIONS. If there is a “green” option to man-made roofing materials, it is a PVC roof. They are 100% recyclable and they can often be installed over your existing roofing system, which eliminates an expensive tear-off and saves having to haul the old roof to a landfill.
