Old flat roof keeps leaking after multiple repairs? Here’s why.
Straight answers from a Mason, OH commercial roofing team that sees this every week.
You run a business in Mason, maybe off I-71 near the industrial parks or over by Deerfield Towne Center. Your flat roof is aging. You have paid for patch after patch. But after every heavy rain, new water spots appear on your ceiling tiles. You are tired of moving inventory and worried about mold.
When a flat roof leaks again and again, the problem is usually under the surface. The top membrane gets all the attention. But water can soak into the insulation layer below. Once that insulation is wet, it holds moisture like a sponge. Every patch you add just traps that water inside. The heat and cold cycles around Mason make it worse. The trapped water expands and contracts, slowly tearing the membrane apart from the inside. If you see bubbles or feel soft spots when you walk the roof, the damage is already deep.
Stopping the cycle means measuring the real damage. A core sample is a simple test. A small plug is cut from the roof to check if the insulation is dry or soaked. If it is wet, a full tear-off and replacement is often the only real fix. For a typical 5,000 square foot commercial roof in Mason, a full replacement can run from $25,000 to $45,000. That cost depends on how many layers need removal, the insulation condition, and the new system you pick. Patching again might cost $800 today but lead to $10,000 in interior damage later.
This week, do not call another repair crew. Call TruRoof for a core sample and a moisture scan. We will map exactly where the water is trapped. Then you get a clear plan with real numbers. No guessing and no more wasted patches. If the insulation is dry, a silicone restoration coating might solve it. If it is wet, we walk you through a full replacement step by step.
Once the new roof is on, you stop watching the weather. No more buckets in the hallway. No more emergency calls after a storm. Your inventory stays dry. Your ceiling stays clean. You get back to running your business, not your roof.
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."
Other things people in Mason 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.
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.
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.
