Single-Ply Membrane Roofing System for Commercial Buildings

 In Blog

Two critical factors in a commercial roof are the ability to both insulate and protect against the elements. A single-ply membrane roofing systems do both and have quickly become the go-to roofing system for commercial facilities. Depending on the materials used, a flat roof can last for decades. While they vary in style and function, all are affordable and durable roofing solutions for commercial buildings. 

Types of single-ply membrane roofing systems

All single-ply membrane roofs are rubber sheets attached to insulation covering your entire roof. The most popular types of flat roofs are: 

  • Ethylene Propylene Diene Terpolymer (EPDM)
  • Thermoplastic Polyolefin (TPO) 
  • Polyvinyl Chloride (PVC)

TPO flat roofs are known as the “white roof” and are proficient at reflecting and diverting UV rays and heat from the sun.

Flat roofing systems have dominated the commercial market for decades, and their track records speak for themselves. While all three are high-performing systems, choosing the right style for you will depend on your building and your local climate. 

Choosing Between EPDM, TPO, and PVC

EPDM has been around the longest and is seen on commercial buildings worldwide, recognized by its dark surface. The heating retention properties and weather resistance make EPDM a great choice for businesses in any climate. The rubber membrane is tough yet flexible enough to accommodate extreme heat and temperature fluctuations. 

TPO roofs are white, in contrast to EPDM. The white or light colors are very effective in warmer climates. Reflecting the sunlight and diverting heat and energy makes them great at protecting buildings and keeping cool on hot summer days. The high-reflexive properties make TPO more energy-efficient than EPDM.

While EPDM stands tough against harmful UV rays, it will retain the heat, not reflect it away, which is why their Energy Star rating is lower than TPO.  

PVC has the same reflective properties and great energy efficiency as EPDM and TPO. However, the installation process gives PVC a bit of extra strength and durability in the seams. 

The Right Insulation  

All three only function alongside the right type of insulation material. While a single-ply membrane roofing system appears simple in design, finding the right combination of insulation and style of flat roof materials is vital to the performance and function of the roof.
