I had an outstanding experience working with Great Lakes Roofing Corporation on our commercial flat roof in Kenosha. From my very first conversation with Anthony “Tony” Lloyd, I felt completely comfortable and confident. Tony took the time to listen when I explained the existing standing water issue that had previously damaged the membrane. He recommended a full roof replacement as the solution, and his professionalism and straightforward approach gave me such confidence that I paid for the entire project upfront.
The crew did an excellent job installing the new reinforced membrane system. The work was clean, professional, and safety-conscious. I was particularly impressed with the quality of the installation and the peace of mind that comes with the 25-year manufacturer’s warranty and the 20-year labor warranty from Great Lakes Roofing.
After the project was completed, I noticed the standing water was still present in the low area. Tony had assured me that if the water caused any issues with the new membrane, it would be covered under warranty. Shortly afterward, Christian Hartwig, my assigned account manager, proactively reached out to follow up on the project. When I explained the situation, he immediately took ownership and committed to thoroughly investigating the issue to make sure it is properly resolved.
Overall, Great Lakes Roofing is a professional, trustworthy company that stands behind its work. I would confidently recommend them to other commercial property owners in Wisconsin. I’m very pleased with the experience and feel confident that Christian will ensure this remaining detail is handled correctly to our full satisfaction.

They were professional at every step. Here when they said they would be here and the job was done in a timely matter. We appreciate roofers they have a very tough job. Not only working hard but trying to stop water and gravity is a tall task. Thanks, Great Lakes Roofing.

Every aspect of our roofing project was a good experience, thanks to Great Lakes Roofing. The crew showed up on time and worked very hard to get our roof replaced in what felt like record time. Our roof looks great and we are very pleased. Our project manager Greg was fantastic to work with, as was Alicia. Thank you Great Lakes!
