Single Ply Roofing

Single ply roofing systems consist of one layer of material which has long-proven performance. After 30 years of use in the commercial roofing industry, Single Ply roofing is the number one choice for a superb roofing system. Most of the products, systems and accessories we offer are Single Ply.

There are many types of single ply products, most of them designated by the initials of their principal chemical compound. One of the most popular membrane materials is PVC, a flexible version of polyvinyl-chloride. Another rubber-like membrane is EPDM, ethylene-propylene-diene-monomer.

Green Star Commercial Roofing installs many different single ply roof system including: TPO, PVC, TPA, PIB, EPDM, and Hypalon. When selecting a single-ply system, it is imperative that you consult your project manager to tailor to the specific project.


tpo-thermal-polymer-olefin.Thermoplastic polyolefin orThermal Polymer Olefin(TPO) is comprised of materials combined in a thermal reactor at a molecular level; lightweight, highly resistant to tears, impact, punctures and wind uplift. Once combined, the molecules fuse together and material cannot be separated, as opposed to other materials that are ground up and melted together.

TPO is one of the lightest, most recyclable materials on the market. With a built-in, ultraviolet protection membrane which reflects sunlight, TPO cools building interiors which translates to energy savings. It is also one of the most weather-resistant materials on the market.

Because TPO is a polymer, it is a great insulator that also protects buildings from the elements, since it does not conduct sound, electricity, or heat – keeping buildings cooler in the summer. Due to the nature of this material, it stands up to even the most extreme weather conditions without expanding or contracting, which is why the automotive industry uses it in fenders, bumpers, doors®, and other body moldings.


pvc-polyvinyl-chloridePolyvinyl Chloride (commonly abbreviated PVC) stands for polyvinyl chloride, meaning it is comprised of carbon, hydrogen, and chlorine (from salt) on a molecular level. When heated sufficiently, thermoplastics temporarily shift from a solid to a semi-solid state enabling the sheets or panels that are overlapped to fuse together as a solid upon cooling. This process yields one, continuous membrane rather than several compressed particles. First appearing on roofs in Europe in the 1960s, PVC has the longest track record in roofing membranes of all thermoplastics and has since been widely tested and perfected. The PVC roofing system membrane has many options and roofing types.

Manufacturers have produced a large array of colors, including white, which is heat reflective. PVC can be attached and adhered in several different ways. These options make PVC roofs completely customizable and aesthetically pleasing. The low-temperature flexibility and high-temperature tolerance points of the membrane, PVC is very flame resistant, impact resistant and resilient. Because of the resilience and performance of PVC, many roofs throughout the United States have been installed over 20 years and are still performing very well.
