TPO or EPDM: Which Single-Ply Membrane Roofing Is for You?

By Stacy Mellete

Single-ply membrane roofing is more commonly used for commercial buildings, but it can be a great choice for residential homes as well. It’s perfect for structures with flat, low-sloped roofs, and is energy-efficient too.

The two most popular types of single-ply membrane roofing are TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer). If you’re not sure which of these two you should get, you should take your time in learning more about their features.

In this guide,  the top local roofing contractor in Tampa FL, Affordable Roofing Systems differentiates TPO and EPDM based on the following factors:

Ease of Installation

TPO needs to be installed through hot air welding. Due to the complex installation process, this type of single-ply roofing must be installed by a professional with specialized skills and knowledge. Meanwhile, EPDM doesn’t require any special equipment making it a good option if easier and faster installation matters to you. 


Both TPO and EPDM are known for being dependable roofing materials. EPDM is typically made from rubber compound, and it offers amazing resistance to UV light, ozone and severe weather conditions. TPO, on the other hand, has a seam strength that is three to four times better than EPDM’s adhesive and tape seams.

Energy Efficiency

TPO is considered as a cool roofing technology, but some TPO products feature sun-reflective properties as well. Due to its ability to keep a cooler thermal balance inside a room, TPO can effectively reduce the need for air conditioning and help lower energy costs. EPDM membranes also have great reflective properties, but they aren’t able to provide the same amount of energy savings as TPO roofs.


TPO is usually more difficult to maintain than EPDM. For instance, the procedure for welding new material to an old TPO membrane may require a special process. In the case of EPDM, you’ll have to watch out for the seams. Since these are only treated with adhesive, they may eventually come apart and require maintenance.


EPDM roofs cost less than TPO roof membranes. But regardless of the single-ply roofing that you prefer, you can get more value for your money if you opt for a thicker membrane. Experts say that EPDM and TPO roofs perform better and last longer if they are thicker.
