Commercial Roofing Systems We Install
Great Lakes is your trusted commercial roofing company in Dubuque for high-performance, energy-efficient commercial roofing systems tailored to meet the needs of every property type. Our most requested solution, TPO roof installation, is popular for its excellent UV resistance, long lifespan, and cost-effective installation, making it ideal for many flat-roof buildings. We also specialize in EPDM roofing, a durable synthetic rubber membrane praised for its flexibility, impact resistance, and ability to withstand extreme weather conditions.
For facilities that require strong chemical resistance and added fire protection, PVC roofing delivers both safety and durability. Looking to combine insulation with waterproofing? Our spray polyurethane foam systems provide seamless, energy-saving protection that reduces utility costs and increases structural performance.

E Frogwell
When it comes to a company that will get the job done right you have to go with Great Lakes Commercial Roofing. Zac is easy to work with and very knowledgeable about many different products and options. Don’t make the mistake I did and call a contractor that is mainly a residential roofer to look at your industrial roof unless you like wasting money
Tom Havacheck
Great company to work with! I have a building in Pennsylvania but live in another state. My roof was leaking and Zac was sent out and did the inspection on the roof. When he was at the building he called and sent me a link to live pictures
Jason Bakus
These guys are awsome. Great job from start to finish. Did our large commercial catering hall. Always available if we have a question or concern. Roof looks great and best of all. No more leeks. Defiantly recommend
Matthew DeLibero

Barb Goliad
I called Great Lakes Commercial Roofing to come check out my building. I had a company put silicone roof coating on it 5 years ago and since day one it never stopped the leaking problems, the other company came out 5 times to “fix the problem” but never did. Zac came out and evaluated my problem and gave me a ton of information on the best solution to fix the problem.
