Reviews
What customers say
Customers praise professional crews and prompt service, and several describe repairs to leaking commercial roofs. One customer says the company repaired and sealed a leaking 155-year-old commercial building rather than recommending a new roof. At a warehouse, a crew returned within 24 hours to fix a minor leak after the job; that customer reports no further issues.

Commercial Flat Roof St Louis. I have used this company for 8 years. They are great!! Prompt, excellent work at a fair price. They always include a warranty. USE THEM!!
Lisa Charles
Anthony and his team are the best! They repaired and sealed the roof on our 155 year old commercial building that was leaking. He didn't try to sell us a new roof saving us thousands of dollars. Plus, his repair work has a 10 year warranty. We are very pleased and highly recommend Commercial Flat Roof Company for any roofing project in St. Louis.

I had an excellent experience with Commercial Flat Roof Company. They repaired the roof on my building, and the results were outstanding. The team was professional, on time, and very knowledgeable about every detail of the job. They identified the issues quickly, explained everything clearly, and made sure the repair was done right. Since the fix, the roof has been perfect — no more leaks or issues. Highly recommend them for any commercial roofing work!

Worked with Commercial Flat Roof to fix the roof on a warehouse. It was an excellent experience! They were able to come out and complete the work within a week of signing, and came in substantially below other bids. We had a minor leak a few days after the work was complete, and a crew was out to fix it within 24 hrs. Since then (5 months ago), we've had zero issues. I will absolutely use them again!

I recently had The Flat Roof Company install a new TPO roof on my 3-family building in the Skinker DeBaliviere neighborhood, and I couldn’t be more impressed. From start to finish, they were professional, responsive, and Anthony was very helpful.
The team worked incredibly fast without cutting corners, and they delivered top-notch workmanship. They also offered a 15-year full warranty, which speaks volumes about the quality and confidence they have in their work.
A special shoutout to Anthony, the owner — his customer service was excellent. He was attentive, knowledgeable, and made the entire process easy and stress-free. It’s rare to find someone so invested in making sure the job gets done right.
Their communication was excellent throughout the project—clear, respectful, and proactive. On top of all that, I got a great price, especially considering the scope and warranty. It’s not easy finding a roofing company that combines value, speed, and professionalism like this.
Highly recommend to anyone looking for roofing work in St. Louis.
