Single Ply Membrane Roofing Systems (TPO, PVC, EPDM)


Single-ply roofing systems are wide width sheeting designed for low slope roofs. They are made out of sheets of rubber or other synthetics, which can be ballasted or chemically attached to insulation to create a single layer of protection for your commercial building.

What are the benefits of single-ply roofing?

  • Lightweight, high performing and resistant to all weather conditions and temperatures
  • Easy to install, long-lasting with the proper maintenance 
  • Maintenance and repair costs are generally lower
  • Once removed can be recycled
  • Ease-of-access for maintenance purposes or repairs
  • It can be easily converted or adapted for green roof installations
  • The material is not easily torn; there is less potential for storm damage
  • Provides a flat surface for equipment like HVAC units
  • Energy efficient
  • UV ray resistant

What does TPO, PVC and EPDM stand for?

TPO stands for Thermoplastic Polyolefin. TPO is a broad family of rubber roofing materials and is a blend of polypropylene and ethylene-propylene rubber.

EPDM stands for Ethylene Propylene Diene Monomer. This is a synthetic rubber made from oil and natural gas. 

PVC stands for Polyvinyl Chloride. PVC is created by a chemical reaction known as polymerization. Polymers can be natural or synthetic compounds. PVC is produced by the gaseous reaction of ethylene with oxygen and hydrochloric acid. 

What are the basic differences between TPO, PVC and EPDM?


TPO is one of the most widely available and used roofing materials in the industry. The main advantage of TPO is its low price. It will also allow your commercial building to be energy-efficient, thanks to its white colour. This allows it to reflect heat and allows for more consistent temperature control, resulting in a reduction in your commercial building energy costs.


PVC roofing membranes can’t be beaten in terms of durability. It can withstand a lot of pressure, whether that be from heavy use or extreme weather and forces of nature. It also has the advantage of being prefabricated, meaning that it will have stronger seams and a more precise fit. The main drawback of PVC roofing is that it is more expensive than TPO and EPDM. While this is something to consider, your roof will also last a considerably longer time, and it will usually be covered under a lifetime warranty. Another benefit is that, since it is prefabricated, this cuts down on installation time, which means lower labour costs. 


EPDM is another popular choice, but again, it comes down to cost as the deciding factor. It is cheaper than PVC, and it has a better track record compared to TPO. However, it is not as strong. EPDM seams and durability fall short in contrast to TPO and PVC.

Which one should I choose?

Each of these materials is similar in terms of composition. You should consider the different individual advantages that each brings, outlined above, and see whether it will fit your property’s needs. If you have a tight budget, ask for quotes from a trusted commercial roofing provider like Aimed Group in Toronto. Some materials might present themselves as the better choice for your particular commercial building and the type of business you conduct inside.
