Performance Meets Affordability
Thermoplastic Polyolefin (TPO) didn't become the fastest-growing commercial roofing membrane by accident. When building owners realized they could get heat-welded seam strength rivaling PVC at a price point closer to EPDM, the decision became obvious. TPO hits the sweet spot that most commercial properties need.
We've installed millions of square feet of TPO across New Jersey and New York—on warehouses that span entire city blocks, apartment complexes with hundreds of penetrations, and retail centers with rooftop HVAC units you could park a car on. Every installation taught us something. Every challenge made our crews sharper. That experience shows in the quality of our seams and the longevity of our projects.

Engineered for Performance
The Northeast throws everything at commercial roofs: summer heat that radiates off asphalt parking lots, winter freezes that test every seam, and spring storms that dump inches of rain in hours. TPO is engineered to handle all of it.
Energy Efficiency
That white surface isn't just aesthetic—it bounces back 85% of solar heat before it ever enters your building. Many owners see cooling costs drop 20-30% the first summer after installation.
Superior Waterproofing
Here's the thing about heat-welded seams: they fuse the membrane at a molecular level. The seam literally becomes stronger than the surrounding material. Water doesn't find a way in because there's no way in.
Cost-Effective
TPO costs less than PVC and metal while delivering performance that rivals both. For building owners watching the bottom line without sacrificing quality, it's often the obvious choice.
Fast Installation
TPO rolls are lightweight and install quickly. That means fewer days with crews on your roof, less disruption to your tenants or operations, and lower labor costs reflected in your quote.
Our Installation Process
A TPO roof is only as good as its installation. We follow a rigorous 4-step protocol to ensure every seam is perfect and every detail is watertight.
Inspection & Analysis
Before we quote a single dollar, we need to understand what we're working with. Our infrared scans reveal moisture trapped in existing insulation—damage you can't see from the surface but that will compromise any new roof installed over it.
- Certified inspection protocols
- Manufacturer warranty compliance
Insulation & Tapering
Flat roofs aren't really flat—or at least they shouldn't be. We install tapered polyiso insulation that creates positive drainage toward your drains and scuppers, eliminating the ponding water that shortens roof life.
- Certified inspection protocols
- Manufacturer warranty compliance
Membrane Installation
Every roll is positioned precisely, with overlap distances measured exactly to spec. Whether we're mechanically fastening or fully adhering, we follow manufacturer protocols to the letter because your warranty depends on it.
- Certified inspection protocols
- Manufacturer warranty compliance
Heat Welding
This is where experience separates good installations from great ones. Our welders move at exactly the right speed and temperature to create seams that will outlast the membrane around them. Too fast and the bond is weak. Too slow and you damage the material.
- Certified inspection protocols
- Manufacturer warranty compliance
Technical Excellence
We're certified installers for GAF, Firestone, and Carlisle—not just paper credentials, but relationships built on installations that pass manufacturer inspections consistently. When you need a warranty that actually covers you, that certification matters.

Maintenance Guide
Proper maintenance extends your TPO roof's lifespan and maintains warranty coverage. Here's what we recommend:
Bi-Annual Inspections
Spring and fall inspections catch issues early. We offer affordable annual maintenance plans.
Drain Clearing
Keep drains and scuppers clear of debris to prevent ponding water, which can degrade the membrane.
Seam & Flashing Checks
Annual inspection of heat-welded seams and flashing around penetrations prevents leaks.
Post-Storm Inspection
After major storms, check for debris impact, membrane displacement, or flashing damage.

TPO Roofing FAQs
How long does a TPO roof last in New Jersey?
A properly installed TPO roof lasts 20-30 years in New Jersey. The key factor is installation quality—heat-welded seams done by certified installers like Genc Construction last the full lifespan, while poorly welded seams can fail in 10 years. We use 60-mil and 80-mil membranes for commercial applications, which provide superior durability compared to thinner 45-mil options.
What is the cost of TPO roofing per square foot in NJ?
TPO roofing costs $6-10 per square foot installed in the NJ/NY metro area. This includes membrane, insulation, and labor. Cost factors include membrane thickness (60-mil standard at $6-8/sq ft, 80-mil premium at $8-10/sq ft), tear-off requirements, insulation R-value, and roof accessibility. A 10,000 sq ft commercial roof typically costs $60,000-$100,000 installed.
Is TPO better than EPDM or PVC roofing?
TPO offers the best value for most commercial buildings. It has heat-welded seams like PVC (stronger than glued EPDM seams) at a lower price point ($6-10 vs $8-12/sq ft for PVC). Choose EPDM for maximum longevity (30-50 years vs 20-30 for TPO) at lower cost ($4-8/sq ft). Choose PVC for restaurants or chemical exposure—PVC resists grease while TPO and EPDM do not.
Do TPO roofs qualify for energy rebates in NJ and NY?
Yes, ENERGY STAR-qualified white TPO membranes qualify for utility rebates and tax incentives in NJ and NY. The white surface reflects 85%+ of solar energy, reducing cooling costs by 20-40%. Many NJ utilities offer $0.05-0.15 per sq ft rebates for cool roofing. TPO also helps achieve LEED certification for green building projects.
How long does TPO roof installation take?
A typical 10,000 sq ft TPO roof installation takes 4-5 working days. Larger projects (20,000+ sq ft) take 1-2 weeks. Factors affecting timeline include tear-off requirements (adds 1-2 days), number of penetrations (HVAC units, drains), weather delays, and building occupancy requirements. We work efficiently to minimize disruption to your operations.
