Types of Single-Ply Membrane Commercial Roofing

The two main types of single-ply membrane commercial roofing include:

  • TPO

    Thermoplastic Polyolefin (TPO) is one of the most sought-after commercial roofing systems. It is designed with a single layer of reinforcing scrim and synthetics, which is used to protect flat roofs. It can effectively reflect UV rays.

  • EPDM

    Ethylene Propylene Diene Monomer (EPDM) is made of a flexible, synthetic rubber compound. This roofing membrane comes in black or white with different thickness levels. It retains heat and keeps your facility warmer during cooler weather.

How Single-Ply Membrane Roofing Is Installed?

Your roofing contractor will begin the installation process by removing or cleaning the existing roof. Then, the insulation layers are installed over the roof. A cover board is attached to the single-ply membrane in any one of the three ways:

  • Chemically adhered
  • Ballasted
  • Mechanically Fastened

Both TPO and EPDM single-ply membranes are designed as sheets. Your contractors will just roll out the sheets on your roof.
