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
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.

Rehoboth Mall needed a replacement of its 30+ year old roof. A new roof was needed to add extra safety and improve energy efficiency. To install the new roofing system CentiMark removed the loose stone via an industrial vacuum, then mechanically attached a 1.2” polysio board along with 60 mil of TPO membrane via RhinoBond. CentiMark also coordinated the removal of 60+ dead roof curbs and penetrations with the owner and tenants before and during roof installation.

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.
