Single-ply roofing systems are an excellent way to protect your existing roofing structure. Single-ply systems come in 2 basic formats – thermoset or thermoplastic. Thermosets are synthetic rubber-based materials, with polymers added to improve UV protection, adjust color, or provide increased reflectivity.
Thermoplastics are broken down by the base materials used, primarily thermoplastics and polyvinyls. Both also have additional polymers added to increase resiliency, strength, color, and/or reflectivity. Determining what type of membrane is best for your building includes a lot of factors, including location, roof pitch, underlying substrate, and personal preference. This is where a partnership with a highly professional roofing company like MK Roofing really matters.

Types of Single-Ply Roof Coverings
There are 2 basic types of single-ply systems, thermoset, and thermoplastic. Within these groups, there are 3 commonly used membrane materials:
EPDM
EPDM, or Ethylene Propylene Diene Monomer, is a thermoset material. To be a little less technical, EPDM is a synthetic rubber compound. Strong and flexible, EPDM single-ply membranes have some wonderful benefits to consider:
- History : EPDM has been on the marketplace for about 60 years. It is a tried-and-true roofing material that has stood the test of time.
- Longevity : EPDM membranes generally have a lifespan of about 20 to 25 years, depending on maintenance, location, and environmental factors.
- Attachment: EPDM is usually mechanically attached to your roofing structure. That means that anchors and screws physically attach the 2 pieces together.
- Seams: Seams are usually fused with seam tape.
PVC
PVC, which stands for polyvinyl chloride, is a thermoplastic material. Designed primarily for flat or low-slope roofs, PVC is manufactured in rolls, which are then rolled onto your roofing structure. In existence since the 1960s, like EPDM, PVC has a long history of successful roof protection. Other considerations for PVC are:
- Energy efficiency : Highly reflective options are available. This reflectivity allows for heat to be deflected from the roofing surface. This creates significantly less electricity demand and may result in savings of up to 50% on your building’s cooling costs.
- Longevity : PVC membrane systems have an average lifespan of around 20 years when properly maintained. Obviously, location and environmental hazards will play a role in how long yours will last.
- Attachment : PVC may be attached either chemically or mechanically, depending on the roof slope, roofing structure, substrate, and owner preference.
- Seams: The seams of PVC membranes are heat fused with a torch, virtually “melting” them together into a seamless, cohesive unit.
TPO
TPO, or Thermoplastic Polyolefin, is another thermoplastic material and is our preferred single ply roof system.
TPO roofing is widely used in commercial applications. It is commonly used on flat or low-sloped roofs, as it provides an effective waterproofing solution for such structures.
