TPO VS. EPDM ROOFING

Choosing the right roofing system could depend on several factors such as geographical location, weather, or external factors like solar panels on the roof. While these play an important part in the decision of what roofing to go with, other factors such as durability, cost, energy efficiency, maintenance, or installation play a part as well.

Comparing TPO to EPDM roofing can be beneficial when deciding what roofing system is the right choice.

The longevity of a commercial roof can be one of the most important factors to consider. 

​

For overlapping roofing systems like TPO and EPDM, the key to longevity is the method by which overlapping seams are attached. Permanently attached seams are the safest method with fewer errors in installation and leaks. EPDM roofing has been around longer, and many roofing contractors have the installation method down to a science, meaning fewer errors and increased longevity. TPO hasn’t been around as long, so it’s difficult to determine its longevity over time.  

Price Point

EPDM roofing is the most economical roofing option. TPO roofing can be a little more costly. However, when considering cost, it is beneficial to plan to include the cost of a thicker membrane in the price as thicker membranes are known to be longer lasting and more cost-efficient. Spending the money upfront on a thick membrane and saving on repairs or replacement over time is better.

Installation

TPO roofing needs to be hot welded for installation. EPDM rubber roofs require no special equipment. For this reason, EPDM roofing is quicker and easier to install. Installation of a TPO roof requires special skill and knowledge and is more complex than an EPDM roof, which is why only an experienced commercial roofer should install this type of roof.

Maintenance

Initially, an EPDM roof will not require much maintenance. However, over time, this could change. EPDM roofing is treated with an adhesive that can wear out and come apart. Thus, EPDM roofing will require maintenance at some point down the road. Also, this type of roofing doesn’t stand up well to solvents and oils, which could damage the membrane. TPO roofing may also require maintenance down the road as seams may need to be hot welded back together.

Energy Efficiency

TPO roofing has become increasingly popular because of its white color and energy efficiency properties. Some TPO roofs are known as “cool” roofs, while others have sun-reflective properties. Because of their ability to reflect the sun’s rays, TPO roofing systems allow the inside of buildings to stay cool, requiring less energy to cool and saving on cooling costs.
