Roof coating vs full replacement for your flat roof?
Fairfield, OH business owners: get straight answers on coatings and replacements from a local commercial roofing contractor.
Your flat commercial roof in Fairfield, maybe over your warehouse off Route 4 or your retail space near Jungle Jim's, is getting old but not completely shot. You've heard about roof coatings—they sound like a smart, lower-cost option. But you're not sure if a coating will really stop the leaks or if you're just covering up a problem that needs full replacement.
Flat roofs in Fairfield take a beating from freeze-thaw cycles and summer heat. Over time, the membrane can crack, blister, or pull away at seams. A roof coating is a thick, liquid-applied layer that can seal small imperfections and reflect UV rays, potentially adding 10-15 years. But it only works if the underlying roof board and insulation are still dry and solid. If water has already soaked the insulation, often from long-standing ponding or repeated leaks, a coating won't fix it. It'll just trap moisture and cause more damage.
A roof coating job typically costs $3 to $6 per square foot, depending on the product and prep. Full replacement with a new membrane and insulation runs $8 to $15 per square foot or more. The coating might take a day or two, while replacement can take a week. But if the insulation is wet, you'll end up paying for a coating now and a replacement later, doubling your cost. The real question isn't just price; it's what's happening under the surface.
Before you decide, get a moisture scan. A thermal imaging scan can detect wet insulation without cutting into the roof. A core sample, a small cut to inspect the layers, confirms what's really going on. TruRoof offers free roof inspections in Fairfield, including moisture scans for flat roofs. We'll give you an honest assessment: if a coating will work, we'll say so. If the roof needs full replacement, we'll explain why, with photos and data. Don't let a salesperson sell you a coating without checking underneath first.
Once you know whether your insulation is dry or wet, the path forward is clear. If the roof is sound, a coating can give you a watertight, energy-efficient surface that lasts a decade or more. If replacement is needed, you'll get a new roof built to handle Fairfield's weather, with proper drainage and insulation. Either way, you'll stop the leaks and stop worrying every time it rains.
What people in Fairfield 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 Fairfield 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.
