Understanding the Different Types of Single-Ply Roofing Systems EPDM and TPO

Single Ply Roofing Systems

When the roof of your commercial or industrial building is in need of replacement, a single-ply roofing system may be your best option in terms of value, speed of installation, and durability. Midwest Roofing offers two different types of single-ply roofing, EPDM and TPO. This post will help you understand these two different types of single-ply roofing systems.

EPDM (Ethylene Propylene Diene Terpolymer)

Benefits

  • Has a long track record of durability and longevity in the roofing industry.
  • EPDM is a rubber compound that is resistant to temperature fluctuations, UV radiation, and degradation caused by ozone exposure.
  • EPDM is manufactured in large sheets which means faster installation and less seams to seal.

Drawbacks

  • Although very dourable, EPDM is not resistant to hydrocarbons that are commonly found in oils, fuels, and cooking grease. This may be an important factor in your roofing decision if your commercial building manufactures or uses these substances.
  • EPDM is considered a thermoset material. A thermoset material does not soften when heated so the seams in an EPDM roof must be sealed using tapes or adhesives.

TPO (Thermoplastic Olefin)

Benefits

  • TPO is a relatively new single-ply roofing material that is made from ethylene propylene rubber.
  • Although TPO hasn't been around as long as EPDM, it is gaining popularity in the roofing industry. According to this article on roofingcalc.com: "TPO roofing membranes have been manufactured in the US since the early 1990's and are now the fastest growing segment of the US single-ply roofing industry."
  • TPO shares some of the same characteristics as EPDM as well as high flexibility, resistance to punctures and tears, and resistance to hydrocarbons.
  • Highly reflective which translates into cooler roof temperatures and decreased HVAC costs.

Drawbacks

  • While TPO is fast becoming a popular roofing choice, it is still relatively new in the industry.
  • Unlike EPDM, TPO is a thermoplastic, so the seams must be hot-air welded together to create a water-tight seal. And while hot-air welded seams may seem more desirable over tape or adhesive sealed seams, hot-air welding may add complexity and time to the roof installation.
