Old commercial flat roof keeps leaking after repairs?
The repair patch isn't holding. Here's what to do next from a commercial roofing team in Alexandria, KY.
You run a business in a building near US-27 or Old Town Alexandria. Your flat roof is 30 years old. You've patched it three times in two years. Water still finds a way in. Now every rainstorm makes you worry about inventory damage. It's a common story for older commercial buildings in Alexandria, KY.
When an old flat roof keeps leaking after several patches, the top layer has likely worn out. Water gets trapped under the membrane. It moves sideways before it drips. Each patch covers one spot, but water finds the next weak point. In a 30-year-old commercial roof, the whole surface may be past its useful life. The seams can split from years of Kentucky sun and freeze-thaw cycles. That is why another patch will not stop the leak.
Cost depends on roof size, insulation condition, and access. A full tear-off and new membrane for a small Alexandria storefront can take two to five days. Larger buildings near I-71 take longer. If the insulation is wet, it must be removed and replaced, which adds cost. A silicone restoration coating may work only if the insulation is dry. The total price often falls between $8 and $14 per square foot for a full replacement in this area. A coating can be half that if the deck is sound.
Stop scheduling more patches. Ask for a core sample of the roof. This small cut shows whether the insulation underneath is wet. If it is wet, a full replacement or silicone restoration may be needed. If it is dry, a coating can buy time. Call TruRoof for a core sample and a straight answer in Alexandria, KY. Do not pay for another patch until you know what is underneath. A local roofer can be on your roof this week to check the real condition.
After a proper fix, rain goes where it should. No more ceiling stains. No more moving inventory before a storm. Your building stays dry, and you stop paying for temporary patches. You get back to running your business on US-27 or in Old Town Alexandria without watching the weather. The roof becomes something you do not think about.
What people in Alexandria 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 Alexandria 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.
