TPO vs EPDM for your flat commercial roof?
A Cheviot commercial roofing contractor explains the real difference between TPO and EPDM for your flat roof.
Your commercial flat roof in Cheviot is showing age. Bubbles, cracks, or ponding water after heavy rain. Different people tell you different things. Some say TPO is the way to go. Others swear by EPDM. You just want the right answer for your building without making a costly mistake.
Your flat roof's membrane is that single layer between your building and the elements. When it fails, you see cracks, bubbles, blisters, or water ponding days after rain. In Cheviot, where summer temps push AC units hard and storms leave standing water, the material choice matters. TPO is white thermoplastic that reflects heat and gets heat-welded at seams for a watertight bond. EPDM is black rubber that absorbs heat but handles ponding water well because its glued seams stay flexible. That difference decides whether your roof leaks in a year or lasts two decades.
Replacing a flat roof on a Cheviot commercial building usually takes one to three weeks, depending on size and tear-off complexity. Cost depends on square footage, insulation needs, and membrane choice. TPO often costs less upfront than EPDM for a full replacement because the material is lighter and installation faster. EPDM can cost more initially but may handle severe ponding better. For most buildings along Harrison Avenue or near I-71, a full tear-off and TPO install runs in the typical range for the region. The biggest cost drivers are deck repairs and how much insulation you need.
Your next step is a roof assessment. Do not let a small leak turn into a deck replacement. A trained eye sees what you cannot: poor drainage, weak seams, insulation damage. TruRoof conducts free flat roof assessments for Cheviot businesses. We walk the roof, measure slope, and tell you whether TPO or EPDM fits your building. You get a written quote and a plan, not a sales pitch.
Once the right membrane is installed, your roof just works. No more ponding water, no blisters, no surprise leaks. Your cooling bills drop because TPO reflects heat. The building stays dry through every Ohio storm. You stop worrying about the roof and get back to running your business.
What people in Cheviot 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."
Other things people in Cheviot ask
can you reroof over an existing flat roof
A recover works when there is one roof layer and dry insulation. A core sample tells us in an hour.
how much does a commercial roof cost
We price by square footage, system and insulation and give you a written proposal you can put in front of the board.
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.
