Roof coating vs full replacement: which one for your flat roof?
Straight answers from TruRoof, commercial roofing serving Aurora, IN.
You run a building in Aurora—maybe a shop near Fox Valley Mall or an office off I-225. The flat roof is getting old. No major cave-ins yet, but you see cracks, blisters, or a slow leak when it storms. Someone mentioned coatings can stretch the budget. You don't want to waste money on a band-aid.
A coating is a liquid-applied layer that seals small cracks and adds sun reflectivity. It works when the roof deck is dry and the membrane is still holding together. If you see puddles that sit for days, soft spots when you walk, or leaks that keep coming back in new places, water has already soaked the insulation below. No coating will fix wet insulation. It just traps moisture inside, where it rots the deck.
In the Aurora area, a coating job on a sound roof can run a few dollars per square foot. A full tear-off and replacement is a bigger investment, often five to eight times more, depending on insulation condition and roof size. But if the core is wet, coating money is gone in two years. You pay twice. A moisture scan and one small core sample tell you which camp you're in, before you spend a dime.
This week, get a flat roof inspection that includes a moisture scan—not just a walk-around. A core cut shows what's happening under the surface. If insulation is dry and seams are tight, a coating could buy you ten years. If insulation is wet, stop patching and plan the replacement. TruRoof can run both the scan and the core sample on your Aurora building, and give you numbers for each path.
After the right call, you stop chasing leaks. Your maintenance costs go flat. You know the roof will hold through the next hailstorm or a heavy Colorado snow season. You made one decision with real data behind it.
What people in Aurora 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 Aurora 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.
