Standing water on your flat roof for days after rain?
That's ponding water. Here's what it means for your building and how to fix it — from roofers in Forest Park, OH.
You look up after a storm and see water still sitting on your flat commercial roof. Around Forest Park, with our mix of heavy spring rains and flat warehouse roofs near strips like Morse Road, this is a common headache. You worry that puddle will find a way through the membrane and into your store or storage area.
Ponding water is exactly what it sounds like. Water that stays on your roof for 48 hours or more after rain stops. On a flat roof, this happens when drains clog with leaves or debris, or when parts of the roof settle and create low spots. The constant weight and moisture put stress on TPO or EPDM seams. Over time, that can crack the membrane and let water into your building.
Fixing ponding water usually starts with a roof inspection. A small low spot might just need a tapered patch added under the membrane to slope water toward a drain. Clogged drains or scuppers need cleaning. If the problem is bigger, like widespread sagging, you may need a partial roof replacement. Costs depend on size. A simple drain cleaning and seam repair could be a few hundred dollars. Replacing a section of roof with new TPO or EPDM runs higher, but it stops the leak threat for good.
This week, walk your roof safely and note where water sits longest. Check your drains for leaves or trash. Then call a roofer who works on commercial flat roofs in Forest Park. TruRoof can send someone to map your low spots and test your membrane. Do not wait until you see a stain on your ceiling. That means water already got through, and the damage behind the drywall is worse than what you see.
Once it is fixed, your roof drains fully after every rain. No standing water, no guessing when a leak might start. Your stock stays dry, your ceiling panels stay clean, and you stop worrying every time the forecast calls for heavy rain over Hamilton County.
What people in Forest Park 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."
