Emergency Commercial Roof Repair
in Mt. Lebanon, PA
24/7 Emergency Commercial Roof Repair for Mt. Lebanon Businesses
Immediate Leak Containment
When water breaches your roof, every minute costs money. Our emergency commercial roof repair crews reach Mt. Lebanon properties around the clock to stop active leaks, protect inventory, and stabilize the building envelope. As your trusted Mt. Lebanon commercial roofing contractors, we arrive with materials on the truck, not a scheduling delay.
Storm and Wind Damage Repair
Western Pennsylvania storms tear membranes, lift flashing, and clog drains fast. We respond to wind-uplift damage, hail impact, and debris punctures across TPO, EPDM, PVC, and metal systems. Our technicians document conditions for your insurance carrier while making the roof watertight, so your operation keeps running through the repair process.
After-Hours and Weekend Service
Commercial roof failures rarely respect business hours. Great Lakes Commercial Roofing staffs emergency response 24 hours a day, seven days a week, including holidays. When a Mt. Lebanon property manager calls at 2 a.m., a live team member answers and dispatches a crew. Because we run zero subcontractors, the technicians arriving overnight are the same trained employees who handle our full replacement projects; no unfamiliar third-party labor on your roof at the worst possible hour.
What Happens During an Emergency Call
Our process is deliberately simple. You call, describe the problem, and we confirm an arrival window. On site, the crew locates the water entry point, applies temporary sealing or membrane patching, and clears drainage obstructions. We photograph everything and provide a written condition summary before leaving. Within 24 hours, you receive a free full inspection and a permanent commercial roof repair recommendation with pricing, so the emergency fix never becomes a long-term unknown.
Emergency Repairs by Roofing System
Membrane and Coating Systems
Most Mt. Lebanon commercial buildings run single-ply or coated roof assemblies, and each fails differently. TPO seams separate under thermal cycling. EPDM shrinks and pulls at penetrations. PVC turns brittle at the edges after years of UV exposure. Spray polyurethane foam absorbs water once the topcoat wears thin.
Our crews carry compatible patching materials for all of these, so repairs bond permanently instead of peeling off in the next freeze-thaw cycle. As a GAF Platinum Elite Commercial Contractor and GAF Coatings Pro Plus applicator, we repair to manufacturer specification and protect existing warranty coverage wherever it still applies.
TPO and PVC Repairs
Heat-welded thermoplastic membranes need heat-welded repairs. We hot-air weld TPO and PVC patches to restore full seam integrity rather than relying on adhesive tape that lifts within a season. Field welds are probe-tested before we leave the roof, confirming the repair holds under standing water and wind load.
EPDM Rubber Repairs
EPDM commonly fails at seams, curbs, and pipe boots. Our crews clean and prime the substrate, then install compatible cover strips and pourable sealer at penetrations. Shrinkage-related tearing at parapet walls gets re-termination hardware, not surface caulk, because caulk-only fixes reopen within months in Pennsylvania winters.
Metal Roof and Flashing Repairs
Loose fasteners, opened panel laps, and failed counterflashing account for most metal roof leaks. We reset and upgrade fasteners, seal laps with butyl tape, and rebuild flashing details at walls and curbs. Where corrosion is widespread, restoration coatings extend service life without a full tear-off investment.

Emergency Repair Costs and Insurance
What Emergency Repairs Cost
Emergency repair pricing depends on system type, access, and damage extent. Temporary stabilization is a fraction of replacement cost. Fixing a leak early almost always costs less than replacing saturated insulation and deck later.
Working With Your Insurance Carrier
Storm damage often qualifies for coverage. We document conditions with dated photos, moisture readings, and written findings your adjuster can act on. While we don’t file claims for you, our reports give carriers the evidence they need, and we’re on site during adjuster visits whenever you request it.
Repair Now or Replace Later?
- Moisture scans show widespread saturated insulation
- The membrane has reached the end of its service life
- Repairs have recurred in the same area repeatedly
- Seam failure is systemic rather than localized

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
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.
