Reliable Commercial Roof Repair
in Mt. Lebanon, PA
Trusted Commercial Roof Repair Services
Fast, Code-Compliant Repairs You Can Count On
With years of trusted Mt. Lebanon commercial roofing services, Great Lakes Commercial Roofing delivers precision repair services built for the demands of local businesses. From minor membrane punctures to widespread storm damage, our factory-trained crews restore performance, protect interior assets, and keep your facility fully operational throughout every repair.
Built for Mt. Lebanon’s Unique Climate
Mt. Lebanon’s freeze-thaw cycles, heavy snow loads, and summer thunderstorms put commercial roofs under constant stress. Our repair specialists understand these regional challenges firsthand and apply targeted solutions – seam sealing, flashing restoration, and membrane patching – designed to withstand western Pennsylvania weather, and when a roof has reached the end of its service life, we also provide full commercial roof replacement in Mt. Lebanon as the most cost-effective long-term path forward.
Why Commercial Roof Repair Matters in Mt. Lebanon
Ignoring small roofing issues is one of the costliest mistakes a commercial property owner can make. A pinhole leak today becomes saturated insulation, mold remediation, and interior damage tomorrow. Our repair-first philosophy helps Mt. Lebanon facility managers preserve capital, protect tenants and inventory, and maintain manufacturer warranty eligibility. By addressing problems early, we help you avoid premature commercial roof replacement and extract maximum value from your existing roofing investment.
A Local Partner With National Certifications
Great Lakes Commercial Roofing brings 99+ years of combined team experience and rare manufacturer credentials to every Mt. Lebanon repair project. As a GAF PlatinumElite™ Commercial Contractor, GAF CoatingsPro+ specialist, and Holcim Elevate Certified installer, we hold the highest designations in the industry. These credentials are reserved for contractors with proven workmanship, financial stability, and technical depth, giving Mt. Lebanon property owners peace of mind that their repair is handled by qualified, accountable professionals, not subcontractors.
Our Commercial Roof Repair Process
From Diagnosis to Lasting Solution
Every commercial roof repair in Mt. Lebanon begins with a thorough diagnostic inspection. Our team uses thermal imaging, moisture detection, and detailed visual assessments to pinpoint the exact source of failure, not just the symptoms. We then document conditions with photos and produce a clear scope of work outlining recommended repairs, materials, and timelines – though when the situation can’t wait, our emergency response team moves immediately.
Once approved, our in-house, security-cleared crews execute the repair with manufacturer-approved methods and materials. We finish with a final quality inspection and provide written documentation for your records, insurance claims, and ongoing maintenance planning, ensuring full accountability from start to finish.
Step One – Comprehensive Roof Inspection
Our certified inspectors evaluate every component of your commercial roof system, including membrane integrity, flashing, drains, penetrations, and insulation. We document each finding with photographs and thermal scans, giving you a complete picture of your roof’s condition and helping prioritize repairs based on urgency, budget, and long-term performance goals.
Step Two – Customized Repair Plan
No two commercial roofs are identical, and neither are our repair plans. We create a tailored scope of work for your Mt. Lebanon property, matching repair techniques and materials to your existing roof system, whether TPO, PVC, EPDM, modified bitumen, or built-up. Every recommendation balances performance, longevity, and budget.
Step Three – Expert Execution and Cleanup
Our factory-trained, never-subcontracted crews complete repairs efficiently and cleanly, minimizing disruption to your daily operations. We follow all OSHA safety protocols, manufacturer specifications, and local code requirements. After completion, we conduct a final inspection, remove all debris, and deliver documentation that supports warranty claims and future maintenance planning – and for roofs nearing the end of their lifespan, we’ll also discuss whether a protective roof coating could delay a full replacement.

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.

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.
