When selecting roofing for a commercial or industrial building, EDPM and TPO roofing are some of the top options. Since the two types of roofing are similar, it's crucial to know the value of each  Consider the following answers to common questions about the critical differences between EDPM and TPO roofing.

TPO Roofing Versus EDPM

What are They? 

TPO roofing is also known as thermoplastic polyolefin. The material is reinforced with talc and fiberglass to create a strength similar to steel. This unique roofing is used on factory roofs and commercial buildings because of its durability and longevity.  Some brands of this material are Energy Star certified, so look for these options if you’re trying to limit your energy use. TPO is stretched over the roof to create a stable, puncture-resistant layer to protect the roofing structure.

EPDM roofing is made out of ethylene propylene diene terpolymer, a rubber roofing material. It's excellent for low-slope buildings because it is water-resistant and durable. EPDM is available in black or white and can be attached to the roof mechanically or in long rolls that are sealed with tape or liquid adhesive. The material may be from 7.5 feet to 50 feet long and comes in 60- and 45-millimeter thicknesses.

Pros and Cons of Each Option 

In warmer climates, many businesses choose TPO because it features more color options and the ability to have a lighter colored roof. This will reflect sunlight and limit the amount of energy necessary to cool the building. Many building owners whose roofs can be seen by the community will choose TPO because of the full range of colors available to add aesthetic value.

However, EPDM is less expensive and offer similar strength to TPO roofing, so those looking for a high-quality yet low-cost solution may opt for EPDM. EPDM only comes in white or black and is not as aesthetically pleasing. Frequently, EPDM is used in factories and other buildings that don’t see consumer foot traffic. Due to the similarity in strength and durability, the aesthetic value is the critical difference between TPO and EPDM.
