Commercial Roof Replacement and Reroof Solutions
When a commercial roof repair in Oil City, PA, is not enough and your roof shows signs of aging or damage, our trusted commercial roofing contractors deliver reliable roof replacement and reroofing solutions that restore long-term performance and protection. Our certified team evaluates your existing system, addresses insulation or decking concerns, and installs high-quality commercial roof systems such as TPO, EPDM, PVC, metal, or SPF roofing.
Every project is completed safely, on time, and without subcontractors, ensuring consistent workmanship from start to finish. Whether you manage an industrial facility or retail center, we design cost-effective reroofing systems that minimize downtime and maximize durability against Pennsylvania’s toughest weather conditions.
At Great Lakes Commercial Roofing, our reroofing process begins with a detailed inspection and moisture analysis to identify underlying problems and determine the best long-term solution. When a full replacement isn’t necessary, we offer overlay systems or coatings that extend your roof’s life while reducing waste and costs. As certified partners with GAF and Mule-Hide, we provide warranties of up to 25 years for added peace of mind.
Every reroof project includes precise installation, thorough cleanup, and clear communication throughout the process. From aging flat roofs to storm-damaged membranes, our commercial roofing contractors ensure your new system is efficient, watertight, and built to last.

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

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

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.
