Your commercial building in Sharonville has a flat roof that’s showing its age—small leaks, some ponding. You’ve heard about roof coatings as a cheaper fix. But you need to know: will a coating actually solve your problem, or just waste money?

Flat roofs in Sharonville take a beating. Freeze-thaw cycles split tiny cracks open, and heavy summer rains find every weak spot. A roof coating is a liquid-applied membrane that seals those surface cracks and reflects UV rays. It can work if the insulation beneath the membrane is still dry and the roof deck is solid. But if water has already soaked into the insulation or you have areas that pond water for more than 48 hours, a coating won’t fix the core problem. In fact, sealing water in can rot the deck faster.

Coating is less expensive upfront. On a typical 5,000-square-foot commercial roof, a silicone or acrylic coating system might cost $10,000 to $20,000, depending on surface prep and existing coating layers. A full tear-off and new membrane runs $30,000 to $50,000, with deck repairs adding more. A coating can give you 5 to 10 extra years; a replacement 20 or more. But if you coat over wet insulation, you could be back for a full replacement in just two years—and you’ll have lost that coating investment.

Don’t guess whether your insulation is dry. The only way to know is with an infrared moisture scan and a core sample. These tests show exactly where moisture has penetrated. TruRoof provides these scans at no charge for commercial property owners in Sharonville. We’ll come out, test your roof, and give you a clear report—no pressure, just facts. Then you can decide between coating and replacement with confidence.

Once you see the real condition of your roof deck, the path forward is obvious. Dry insulation means a coating can save you significant money and stretch your roof’s life. Wet insulation means a full replacement is the only safe bet. Either way, you’ll stop worrying about leaks and know your building is protected.

What people in Sharonville 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."

Other things people in Sharonville 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.

TPO vs EPDM flat roof

TPO is white and reflects heat, which helps cooling costs in summer. EPDM is black rubber and handles ponding water well. For most Cincinnati commercial buildings, TPO is the default choice. Get a roof assessment to match the membrane to your roof's slope and drainage.
