TPO or EPDM? Which flat roof membrane is right for your building?
Straight answers from a Mount Washington commercial roofing contractor. No sales pitch, just what works here.
You’re standing on your flat commercial roof in Mount Washington, OH. You see cracks, blisters, or standing water. Your roofer mentioned TPO and EPDM. Now you have to choose, and you don’t want to pick wrong. This page helps you decide.
TPO is a white plastic sheet. It bounces heat back up, so your cooling bills drop. EPDM is black rubber. It soaks up heat, but it handles ponding water better. Most flat roofs here don’t slope enough to drain fast. That’s why EPDM used to be the go-to. But newer TPO holds up fine on low-slope roofs if the drainage is right.
The cost difference is small. Both run $6 to $9 per square foot installed on a big roof. If your building has lots of rooftop units or tight edges, labor goes up. A roof with bad decking underneath will cost more no matter which top sheet you pick. The real question is not price. It’s how long each lasts on your specific building.
Get a roof assessment this week. A good roofer checks slope, drainage, and how much sun each section gets. TruRoof can walk your Mount Washington building and tell you what makes sense. Don’t just replace what’s up there now without checking. A wrong choice means you do this again in 10 years instead of 25.
Once it’s done, your roof just works. No more patching every spring. No more ceiling stains after a hard rain. Your building stays dry, and your energy bills settle down. You stop thinking about the roof and get back to running your business.
What people in Mount Washington say
"I'm reviewing my two new roofs, on my house and my garage, installed by TruRoof. The company, and Damon Chuke, their representative, helped me work with the insurance company, and with understanding all the details of the whole process. They took out an obsolete chimney, were on time and professional, and the finished roofs and flashing are beautiful. Many compliments from neighbors. Highly recommended by me."
"We have a beautiful condo in a historic building from the 1840s. Late November had a bad leak in the dining room area. I called Britt at TruRoof who came out and inspected the entire roof of the building. He said to do the entire roof could be around $50,000. But then he started laughing and said you need to caulk the area around one of the chimneys. I thought he was nuts, but I did the caulking, which cost me about 25 bucks worth of outdoor caulk, and there are no more leaks. I cannot express my appreciation for his diligence and his honesty. That kind of a company and a person is rare these days. Highly, highly, highly recommend these guys."
"TruRoof did an outstanding job from start to finish. Communication leading up to the start date was great. Once on site and the project started, everything went as discussed, and the crew was very professional."

commercial roof keeps leaking after repairs
When a roof fails despite repeated repairs, the membrane is likely shot. Get a core sample to check insulation. If it is wet, a full replacement or a silicone restoration coating may be needed. Stop wasting money on patches.
roof coating vs replacement flat roof
Coatings work when the roof is still structurally sound and the membrane is intact. If there are multiple leaks, ponding, or wet insulation underneath, a coating won't fix it. Get a moisture scan and a core sample before deciding.
