How to Choose A Commercial Roofing System

When it comes to commercial roofing, it’s about more than keeping your building dry. When deciding on the materials you choose for your installation, there are several things to consider. Since choosing the wrong material for your commercial roof could turn into a costly mistake down the road, we thought we would compile a list to help you in your research. The roofing material you choose for your commercial building depends on your unique project and structure needs. The two most contemporary, long lasting, and low maintenance materials are TPO and EDPM. Here is a brief description of each:


TPO is a synthetic roofing material comprised of polyolefins and plastics. It is typically white and is designed to keep roofs and interiors cool. Here are some benefits to using TPO for your commercial roof:

  • Low maintenance
  • Great if you have a lot of rooftop units, like HVAC equipment
  • Chemical resistant
  • Low environmental impact
  • Mechanically fastened or fully adhered
  • Reflective – saving you money on energy bills
  • A rubber coating can be applied at the end of its useful life, saving you money
    • Reduced labor and material cost
    • Offers potential tax benefits


This commercial roofing material has been in use for over 40 years. EPDM is made out of synthetic rubber and is typically available in black.

TPO and EPDM are both:

  • Typically comes in 45 mil, 60 mil, and 80 mil
  • High performance
  • Puncture resistant
  • Long lasting

So, as you can see, there are many things to consider when choosing the right material for your commercial roofing project. When it comes right down to it, the best way to make the right decision is to speak with a certified professional.
