Single-Ply Membrane roofing is a time-tested roofing option for commercial, industrial and manufacturing facilities. Single-Ply Membrane Roofing is one of the most well-known and recommended types of commercial roofing material, there are variety of roofing systems to fit your budget and facility needs.
There are two main types of single-ply membrane commercial roofing: Thermoplastic Polyolefin (TPO) and Ethylene Propylene Diene Terpolymer (EPDM). They differentiate in their own chemical makeup, how they are installed and their energy efficiencies.
Thermoplastic Polyolefin or (TPO) for short is a type of single-ply roofing membrane. This is one of the fastest growing commercial roofing systems on the market to date. TPO roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs.
TPO has gained industry acceptance with the natural reflective surface to reflect UV rays. As reported by the National Roofing Contractors Association (NRCA) TPO takes up about 40% of the commercial roofing market share.
Ethylene Propylene Diene Monomer is a type of single-ply membrane that consists of a synthetic rubber compound that allows it to be flexible. EPDM has been used on commercial roofing facilities since the 1960s and is considered a time-tested option. Although EPDM has more of a trusted history with commercial roofing, it only has about 20% of the commercial roofing market according to the NRCA.
With EPDM, you have an option of choosing from a variety of thickness 45, 60, or 90 milliliters and either black or white for the color. While TPO has a natural white color, EPDM usually results in a dark gray or black color for your commercial roof. While the darker color is not helpful in reflecting UV rays, it does retain heat and can be useful in cooler weather.
For an average 20,000 sq. foot commercial roof, it will usually cost between $3.50 and $7.50 per square foot in materials and labor to install a typical single-ply membrane commercial roofing system.

There are a few types of insulation options the business manager/owner can to choose from: Polyisocyanurate, Expanded Polystyrene. Extruded Polystyrene.
Choice of Reflective or Retentive Properties
TPO is generally manufactured white and highly reflective while EPDM is often described as “Black Roofs,” due to the natural dark color of the membrane.
Installing single-ply membrane roofing is relatively simple. There are three ways to attach the membrane to the cover board: ballasted, with an adhesive or mechanically fastened.
