TPO Roofing vs EPDM: Which Do I Need for My Building?

Are you a commercial property owner or manager near Atlanta, Georgia considering the differences of TPO roofing vs EPDM?

Whether you’re selecting roofing materials for a new building or replacing an existing flat roof, you’re likely wondering about advantages and disadvantages.

If you’re comparing TPO roofing vs EPDM, you should know that both are good choices. You might be surprised to learn that building diagnostic experts only link materials to 10% of commercial roof leaks. About a quarter of leaks are linked to design faults, whereas around two-thirds fail due to construction.

If you select an experienced commercial roofing service, you should know that both TPO and EPDM are excellent choices. The question is not “Which one is best,” but rather, “Which one is best for you.”

Below, we’ll explore the main benefits of both. Keep Reading!

TPO Roofing vs EPDM

The pros and cons of different roofing materials lie in their intended use. When you contact a commercial roofing contractor for a quote, let them know which type of business you run because it can make a difference.

Both TPO and EPDM are types of single-ply membranes, and the materials have come a long way since they were first introduced in the early 1980s.

What Is TPO Roofing

Thermoplastic Polyolefin (TPO) is a single-ply membrane of synthetic, reinforced with a polyester scrim. The expected lifespan is often cited as 15-20 years.

The main advantage of TPO roofing is that it is usually white, in addition to grey and tan. This is desirable because a reflective material can stay cooler in a sunny environment. For this reason, TPO is a very energy-efficient roofing material, reducing cooling costs and saving money.

Furthermore, TPO has UV resistant properties, aiding its durability. It’s also considered less at risk of leaks with age since the seams aren’t as big as with EPDM roofs. That said, TPO can become less flexible and crack over time.

Price is similar between the two materials, with TPO being occasionally more affordable. TPO has chemical-resistant properties, which might be a key factor for companies in certain manufacturing industries.

What Is EPDM Roofing?

Ethylene Propylene Diene Monomer (EPDM) is a single-ply membrane with a compound of synthetic rubber. EPDM is usually expected to last around 20-25 years.

EPDM roofing membrane has been around a little longer than TPO, so the technology has had more opportunities to advance. In real-world performance, both types of roofs can perform well if properly maintained.

The color of EPDM is black, so it doesn’t have the energy efficiency benefits of TPO. It does have better resistance to seasonal temperature changes, however, making it more durable in climates with weather extremes. EPDM is also impact resistant, so hail and storm debris will have less of a negative effect.

An EPDM roof is easy to repair or restore, especially as EPDM roofs are ballasted roofs, meaning covered with gravel.
