PVC Roof Systems for Commercial Buildings

Thermoplastic roofs are synthetic substances that become soft when exposed to heat, but harden upon cooling. The flexibility of the membrane allows it to shrink and expand with the rest of the building during shifts in temperature. For example, suppose your location experiences extreme temperature changes between seasons or times of the day. In that case, you want your roof to be able to keep up with the rest of your building's materials, from concrete to steel.   

At CentiMark, we install and service two types of thermoplastic roofs -- Polyvinyl Chloride (PVC) and Thermoplastic Polyolefin (TPO) systems. 

First installed in the early 1960s, PVC was the industry's answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels typically used in system manufacturing. Engineers discovered that adding solid plasticizers to the PVC membrane allowed for additional durability and flexibility, where the membrane alone would be more susceptible to seasonal climate changes. To this day, PVC membranes remain incredibly versatile, chemical resistant and highly recommended for roof-over projects. They are available in various colors, thicknesses, widths and reinforcements, making them an excellent option for almost any roofing project. Along with the environmental benefit of using (fewer) fossil fuels in manufacturing, PVC is highly reflective, making the membrane an energy-efficient option for warmer climates. PVC roofing has the longest track record of all thermoplastic roof membranes.
