TPO vs EPDM: Which flat roof membrane is right? (2025 guide for commercial buildings)
Straight answers for Fairfield, OH businesses. TruRoof helps you pick the right commercial roofing system.
Your flat roof is showing its age. Water pools after rain. You hear TPO is modern and white. But EPDM has been around for decades. Which one actually works for a commercial building in Fairfield’s hot summers and sudden downpours?
TPO is a white plastic membrane that reflects sunlight. It keeps your building cooler in summer. That matters when your AC unit runs hard along Route 4 and I-275. EPDM is black rubber. It absorbs heat but handles standing water well. If your roof near Water Works Park holds puddles, EPDM is forgiving. Both are single-ply systems. Both get installed in large sheets over insulation. The choice boils down to one thing: what does your roof need most, heat reflection or ponding water tolerance?
For a small office roof in Fairfield Crossings, TPO might run $6 to $9 per square foot installed. EPDM is similar, maybe a dollar less. Size changes everything. A warehouse near Symmes Corner costs more because of the square footage. Tear-off adds cost. If your deck is rotten from old leaks, that adds more. A ballpark for a 5,000-square-foot roof is $30,000 to $50,000. These are rough numbers. Every roof is different. What looks like a simple job can hide wet insulation underneath.
Do not patch a failing roof and hope for the best. Call TruRoof for a roof assessment. We walk your roof in Fairfield and check the slope, drainage, and deck condition. We measure ponding areas after a rain. We look at your energy bills. Then we tell you which membrane fits your building. No guessing. No selling you what we have in stock. Just a clear recommendation based on your actual roof.
Once the new membrane is on, your roof works for you. TPO reflects heat and lowers cooling costs. EPDM handles water and lasts 20 to 30 years. Either way, leaks stop. Tenants stop complaining. You stop worrying every time it rains. The roof just does its job.
What people in Fairfield 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.
