Roof coating vs. full replacement: Which one does your flat roof need?
Straight answers about flat commercial roofs from TruRoof, serving Alexandria, KY.
You manage a commercial building in Alexandria—maybe a shop along US-27, an office near A.J. Jolly Park, or a church in Old Town. Your flat roof is older but not gone. You've heard coatings can stretch its life. You don't want to waste money if the real problem is underneath.
A coating seals small cracks and reflects heat, but only if the roof structure is sound. If you see ponding water, blisters, or soft spots when you walk, the membrane or insulation underneath could be rotting. Coatings are like a raincoat—they protect, but they can't fix wet clothes.
For a typical commercial flat roof in Campbell County, a coating might run a few dollars per square foot. A full tear-off and replacement costs more up front, but it resets the clock entirely. The real price depends on what's hiding below. Wet insulation or rotted decking makes a coating a short-term gamble that can double your cost later.
Before you decide, get a moisture scan and a small core sample of your roof. That quick test tells you whether water is trapped inside. TruRoof can perform this assessment without any pressure to buy. Don't let a salesman talk you into a coating without seeing what your insulation looks like first.
Once the right fix is in place, your building stays dry through Kentucky storms. You'll stop worrying about every rain. If a coating truly fits your roof, you'll see lower energy bills too from the reflective surface. Either way, you know you made the call with real data.
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

A recover works when there is one roof layer and dry insulation. A core sample tells us in an hour.

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.
