TPO: Thermoplastic Polyolefin and PVC: Polyvinyl Chloride


What are TPO and PVC?

These roof systems are synthetic substances that are softened when heated, but harden upon cooling. These roof membranes are single-ply and can be installed using a variety of methods including mechanical attachment, point-affixed and fully adhered.

Benefits of TPO and PVC
Flexible protection.

TPO Roof Systems

TPO membranes are made with a co-polymerized rubber that allows them greater flexibility in cold climates. This membrane is best recognized for having the benefits of EPDM and PVC systems, at a more economical cost. TPO membranes are white and highly-reflective, making them an excellent choice for those looking to reduce energy costs. In addition to being ENERGY STAR rated, TPO’s recyclability makes it an environmentally conscious system. Additionally, TPO roofs are durable and resist dirt, bacteria and debris build-up making them highly resistant to tears, punctures and impact damage.

PVC Roof Systems

First installed in the early 1960’s, PVC was the industry’s answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels normally used in system manufacturing. Engineers discovered that adding additional solid plasticizers to the PVC membrane allowed for additional weatherability 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 are highly recommended for roof-over projects. They are available in a variety of 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 the manufacturing process, PVC is highly reflective/UV resistant, making the membrane an energy efficient option for warmer climates.

A Wood Processing Plant Project


A wood processing plant was in need of a roof replacement after years of deferred maintenance which lead to wet insulation, deteriorated decking, interior product damage and ultimately lost production. One section of the roof was a complete tear off and the other two were retrofits. CentiMark had to be extremely careful with all safety processes and procedures due to the deck replacement, working around operating machinery and working around the electrical components which powered the entire plant. In addition to the roof replacement, CentiMark also replaced five plexiglass skylights with new solar light pipes.

Food Texture / Stabilization Company Project


After multiple other contractors unsuccessfully attempted to repair the standing seam metal panel roof for this food texture / stabilization company, CentiMark was called in. The solution was to fully replace the existing roof as it was at the end of its life-cycle and repairs would only delay the inevitable.
