Choosing the right partner for commercial flat roofing is essential for long-term durability, and our process ensures your project stays aligned with your goals from day one. We begin with a detailed inspection that evaluates structural load, existing roof conditions, moisture levels, and potential drainage vulnerabilities. After gathering this information, we provide tailored recommendations backed by manufacturer-certified installation standards and clear project timelines. During construction, our in-house technicians maintain strict oversight to protect warranty coverage and ensure dependable results.
We communicate progress at each step so facility managers, ownership groups, and contractors remain informed and confident. Cedar Rapids businesses appreciate our commitment to safety, organization, and clean work areas; especially on active commercial sites.

Commercial Flat Roofing Solutions
Before starting a commercial flat roofing installation, our team evaluates your building’s exposure to snow load, wind uplift, drainage challenges, and seasonal thermal expansion before recommending the right materials. We install TPO, PVC, modified bitumen system installations, EPDM roofing, and advanced insulation systems that enhance energy efficiency and maintain reliable performance in extreme temperature fluctuations. Each system is engineered to handle freeze-thaw cycles while resisting punctures, standing water, and UV degradation.
We combine technical precision with practical Iowa-focused expertise, giving your business a roof designed for long-term protection. With our in-house specialists overseeing every detail, your flat roofing system is installed with workmanship that meets or exceeds manufacturer and industry standards. You receive a roofing solution that supports longevity, safety, and efficiency.
Our climate-focused design approach goes beyond material selection. We examine every detail of your roof’s infrastructure, including slope optimization, drainage pathways, vapor barriers, insulation thickness, and membrane fastening patterns. This comprehensive assessment ensures your roofing system performs consistently across all seasons, even during heavy snowfall or extended periods of heat. Cedar Rapids business owners value our straightforward communication and ability to tailor solutions that address both immediate needs and long-term performance.
We also help customers understand warranty options, maintenance strategies, and upgrades that improve energy efficiency and reduce operational costs over time. When your property requires specialized solutions, such as increased puncture resistance for high-traffic rooftop areas, reinforcement for mechanical equipment zones, or waterproofing enhancements, we deliver results grounded in technical expertise.
With long-lasting materials, precise installation, and a team committed to craftsmanship, your commercial flat roof will stand strong against Iowa’s unpredictable climate and ongoing environmental demands.

Russell Jenkins
The guys from Great Lakes commercial roofing LLC were extremely professional. Kenneth came out and was extremely informative and knowledgeable in regards to roofing.

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

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.
