Roof coating vs. full replacement: Which is right for your flat roof?
Honest answers about roof coatings vs. replacement from TruRoof, a commercial roofing contractor in Hebron, KY.
If you own a warehouse, office, or retail space in Hebron, KY, you’ve probably noticed some leaks or worn spots on your flat roof. You’re hearing about roof coatings as a cheaper option than full replacement. But you need to know if it’s a smart investment or just money down the drain.
You’re seeing cracked seams, blisters, or small leaks. On flat roofs, the waterproof layer (membrane) wears out from sun, ponding water, and temperature swings. A coating is a liquid-applied layer that seals the surface and reflects UV. It works if the underlying roof deck and insulation are dry and sound. If water has been trapped underneath, a coating can’t fix the damage buried below.
Coating a flat roof usually costs a fraction of a full tear-off. Price depends on the condition of the existing roof and the coating type. For a typical commercial building in Boone County, a silicone coating might run several thousand dollars, while a full replacement could be three to four times that. But if there’s ponding water or wet insulation, a coating won’t last more than a few years. You could be paying twice if you coat a bad roof.
Before you decide, get a moisture survey. This week, call a contractor who can do an infrared scan and take a small core sample to check the insulation. Without that, you’re guessing. If the deck is solid and dry, a coating can buy you 10-15 more years. If not, you need a replacement. TruRoof offers free roof assessments in Hebron and will show you exactly what’s happening under the surface. Don’t coat a failing roof just because the price looks good.
Once you know the truth about your roof, you can plan with confidence. Whether you choose coating or replacement, the right fix means no more leaks, lower energy bills, and peace of mind for years. Your building stays dry and your tenants happy.
What people in Hebron 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 Hebron 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.
