Commercial Flat Roof Company Reviews

I had an amazing experience with this company! Although their name is Commercial Flat Roof Company, they were happy to take on my residential flat roof in South City. I couldn’t be happier with the results and overall communications. Anthony and Isidora were very responsive and worked with my renter’s night schedule on installation dates. One thing to note, the only way you would know they were on your property is by the pictures they provide you. Their cleanup was exceptional. Not a single screw or piece of trash was left anywhere. :)

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!

Spoke with Anthony and scheduled a time to have him come assess our roof project. I sent him two emails at the address he provided with no response. When my husband called to find out if he was coming on the day we agreed upon, he acted as if he never spoke with me. Seemed unprofessional and didn’t offer to come another time.

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!

Excellent customer experience. Had them install two TPO roofs for me in South Tower Grove on historic houses. They came back 6 years later to repair a leak from bullet holes on one of the roofs. (Gotta love the City.) They were very responsive and professional. Took lots of pics while inspecting the leak and identified a few other, non-roof, things that needed repair. Highly recommend.

I reached out to Commercial Flat Roof to do a fix on my business' warehouse roof. I cannot be more pleased with the process and results. Highlights: - Angelo is an excellent project manager -- he was extremely responsive, comfortable texting with me about the progress, and was a strong advocate for my needs as the client - They were able to come out and complete the service within a few DAYS (other companies were quoting 2-3 months out) - They helped find a solution that met my budget and expectations I will absolutely recommend them + use them in the future. So grateful I found them!

I had a great experience with Commercial Flat Roof Company. I chose them because they only do flat roofs and they specialize in this area. I would rather have someone who specializes in an area than a jack if all trades. Anthony was very good to work with, and his pricing was very fair.

The crew were receptive to our needs and extremely professional from start to finish. We are a small VFW Post and I feel like the entire crew went the extra mile to resolve our roof issues. We were kept informed throughout the entire repair/replacement. The roof looks great and was completed in a very timely manner. I want to send a big Thank you from the St Francois County VFW. I would highly recommend the Flat Roof Company for you roofing needs. Thanks again.
