Standing water on your flat roof? Here’s what to do.
How to stop ponding water on commercial flat roofs, from a TPO and EPDM flat roofing team in Mason, OH.
You look up after a rain and see water just sitting there. Days later, it’s still there. That ponding water on your Mason warehouse or store roof isn’t normal. It means drains are clogged, the slope is off, or the membrane has settled wrong.
Ponding water is water that stays on a flat roof for more than 48 hours after rain. It happens when drains get blocked by leaves or debris, or when the roof deck sags over time. On TPO and EPDM roofs, standing water puts constant pressure on the seams. That pressure can slowly pull the membrane apart and let water into your building.
Fixing ponding water depends on what’s causing it. A simple drain cleanout might take an hour. Adding a tapered insulation system to fix the slope costs more and takes a few days. Most repairs fall between a few hundred and a couple thousand dollars. If the membrane is old and brittle, a full replacement might be the smarter long-term move. Every roof is different, so a walk-through is the only way to get a real number.
First, check your gutters and drains for leaves or trash. Clear anything you can reach safely. Do not puncture the membrane or try to patch it yourself. That can make things worse. Then call TruRoof to inspect the roof. We check every seam, drain, and low spot on commercial roofs across Warren County. We’ll tell you what you need and what you don’t.
After the fix, water flows to the drains like it should. The roof dries fast after a storm. You stop worrying every time it rains. Your inventory, equipment, and daily work stay dry.
What people in Mason 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."
