Commercial Roof Replacement
in Corry, PA
Trusted Commercial Roof Replacements for Corry Businesses
Zero Subcontractors
As your trusted roofing company providing expert commercial roofing services in Corry, PA, Great Lakes installs every commercial roof replacement with our own employees trained in-house on the exact systems we install. No subcontractors means no quality gaps, no schedule surprises, and no finger-pointing in Corry, PA.
25-Year GAF Product Warranty Included
Our standard commercial roof replacements come backed by a 25-year GAF product warranty; only available through GAF Platinum Elite Commercial Contractors like Great Lakes. That’s decades of protection for Corry businesses, not a handshake promise.
Built for Corry’s Climate and Freeze-Thaw Cycles
Corry sits in the heart of Northwestern PA’s snow belt, where lake-effect snow, prolonged freeze-thaw cycles, and driving winds punish commercial roofs year-round. We spec every replacement to handle those specific stresses; correct insulation R-values, wind-uplift-rated attachment patterns, and proper slope to drain. Generic replacements fail early here. Our systems are engineered to perform, protecting your building envelope and energy costs through every Corry winter.
Multi-System Expertise — TPO, EPDM, PVC, SPF, Coatings, and Metal
Not every commercial building needs the same roof. Some benefit from reflective TPO to reduce cooling costs. Others perform best with durable EPDM, PVC chemical resistance, spray foam insulation value, or a standing seam metal roof. As a multi-certified contractor: GAF, Holcim Elevate, Mule-Hide, American Weather Star, and Garland, we recommend the commercial roofing system that fits your building, your budget, and your long-term goals.
Commercial Roof Replacement Systems We Install
The Right System for Every Commercial Property
Average commercial roof replacements are an expensive investment, so the system you choose and the contractor you choose to install it matter. Great Lakes Commercial Roofing engineers each Corry replacement around your building’s use, exposure, budget, and energy goals.
We walk you through every option with transparent pricing, real performance data, and warranty specifics – and once your new system is installed, a commercial roof maintenance plan in Corry ensures it performs at full capacity for decades to come. We self-install with our own crews using premium materials from GAF, Holcim, Mule-Hide, American Weather Star, and Garland. The result: a commercial roof replacement designed to last decades, not just get you through the next storm season.
TPO Roof Replacement: Corry’s Most Popular System
TPO is the most-installed commercial roof in Corry for good reason: reflective white membrane lowers cooling bills, welded seams resist leaks, and 20-30 year lifespans make it highly cost-effective.
EPDM Rubber Roof Replacement
EPDM is proven, affordable, and flexible in cold climates, a smart pick for Corry buildings needing a long-lasting, low-maintenance single-ply replacement backed by decades of field performance.
PVC and SPF Roof Replacement
PVC excels on roofs exposed to grease, chemicals, or high foot traffic. Spray polyurethane foam adds continuous insulation and seamless waterproofing, ideal for re-roofing over sound existing substrates.

Signs It's Time to Replace Your Commercial Roof
When Repairs Stop Making Financial Sense
If you’re paying for recurring commercial roof repairs every season, saturated insulation is raising your energy bills, or your roof is past 20 years old, a full replacement is almost always more cost-effective than continued patching.
Structural and Safety Warning Signs
Sagging decking, widespread ponding, failed fasteners, large membrane separations, and mold in the insulation are clear signals that your Corry commercial roof has reached end-of-life – unlike the localized issues that commercial roof repair in Corry can resolve before they compound into full system failure.
Why Replacing Proactively Protects Your Corry Business
- Roof is 20+ years old with original membrane
- Repeat repairs at multiple locations each year
- Visible ponding water 48+ hours after rain
- Rising heating and cooling costs
- Wet or compressed insulation discovered during inspection
- Widespread membrane shrinkage, cracking, or blistering
A planned commercial roof replacement protects your building, your tenants, and your bottom line for decades.

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. We were extremely pleased with his work and the end product. We highly recommend Kenneth and the guys from Great Lakes commercial 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
Matthew DeLibero

Conrad Miler
Your dedication to quality and service have made working with you a pleasure!
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.
