In recent years, single ply roofing has been a popular choice for commercial roofs. Polymer sheets in a single-ply membrane roof are made up of thermoplastics and synthetic rubber, which can be subdivided into two categories. As a result of thermoplastics’ ability to be heated and molded repeatedly, many commercial roofing contractors now use them exclusively when installing flat roofs.

Types of Commercial Roof Single-Ply Systems
Single-ply systems come in 3 primary forms. Each offers distinct benefits, so a short discussion is necessary for you to determine which might work best for you.
TPO. TPO or thermoplastic polyolefin if you prefer the technical term, is considered the gold standard of single-ply systems. It is also the most expensive initial investment. Tough and durable, TPO is primarily available in white, gray and tan. The white is highly reflective, with up to 85% of solar rays directed away from the roof. This increases your building’s energy efficiency levels substantially.
TPO is known for its UV resistance, wind up-lift resistance and longevity, with warranties of 20 years being common.
TPO can be adhered to your roofing system either mechanically (with fasteners), chemically (with adhesives) or ballasted (with rock). The seams are generally heat-welded together.
PVC. Thermoplastic polyvinyl chloride, better known as PVC, is probably the most common single-ply membrane system on commercial roofs today. As a long-term, cost effective roofing solution, PVC is pretty amazing. When you couple that with an Energy Star rating due to reflectivity, and cool roof incentives, there are a lot of reasons to seriously consider PVC as your single-ply choice.
PVC is known for being extremely resistant to chemicals, oil, and grease. It is the preferred system for buildings housing certain types of manufacturing, food production or restaurants.
Like TPO, PVC can be attached to your existing system mechanically, chemically or ballasted. The seams are generally heat-welded together.
EPDM. Ethylene propylene diene monomer is a mouthful, so EPDM or Rubber is the industry term we use. With over 40 years in the industry, EPDM is the best established single-ply system. Also known as “rubber roofing”, EPDM is a rubber based synthetic material known for decades for enhanced waterproofing, durability and increased roof longevity.
Primarily in black, a newer white version has been added to the market to improve reflectivity and address the cool roof trends. EPDM is extremely resistant to foot traffic and weather-related damage.
Best adhered chemically, the newer versions also feature chemical adhesive areas at the seams to allow for faster installation, while reducing the risk of failure due to poor seam adhesion
Benefits:
Any roofing material must be able to withstand the destructive effects of ultraviolet radiation. Single ply membranes are not only 100% UV resistant, but they are also resistant to the growth of potentially hazardous micro-organisms. A hot air weld on the single ply roof membrane also offers your building with some much-needed weatherproofing, even in the most harsh temperatures.
Single ply membrane roofs are also fire-resistant and self-extinguishing because of their composition. Single ply roofing is an excellent choice for any business, organization, or workplace worried about the safety of its employees, visitors, or customers. You may rest easy knowing that your roofing material protects you and your structure from acid rain and other forms of acidic outflow in places that are prone to be exposed to dangerous chemicals. Single ply membranes are far more environmentally benign than standard industrial roofing materials in terms of their manufacture, endurance, and capacity to be recycled.
