TPO Roofing in NJ | Flat Roof Installation & Repair
Morris Renovations installs and repairs TPO roofing systems on flat and low-slope roofs throughout New Jersey. TPO (Thermoplastic Polyolefin) is the leading choice for flat roofs on NJ homes and commercial buildings, combining energy efficiency, durability, and competitive pricing.
What Is TPO Roofing?
TPO is a single-ply white reflective membrane that is heat-welded at seams to create a watertight, seamless surface. It is particularly well-suited to flat or low-slope roofs common on NJ additions, garages, commercial buildings, and certain modern homes.
Benefits of TPO Roofing
- Energy efficient: White surface reflects up to 90% of UV rays, significantly reducing cooling costs
- Heat-welded seams: Unlike EPDM, TPO seams are fused, not glued, creating a bond stronger than the membrane itself
- Lightweight: Adds minimal structural load compared to tile or built-up roofing systems
- Flexible in cold: Resists cracking and brittleness in NJ winters
- Chemical resistant: Handles rooftop HVAC condensate and oils without degrading
- Cost-effective: More affordable than PVC while providing similar performance

Frequently Asked Questions
How long does TPO installation take?
Most residential flat roofs (500-1,500 sq ft) are completed in 1-2 days. Larger commercial projects may take 3-5 days.
Can TPO be installed over my existing flat roof?
In some cases yes, if the existing substrate is sound and relatively flat. We inspect first to determine if overlay or full tear-off is appropriate.
Do you offer TPO roof warranties?
Yes. Manufacturer warranties of 10-20 years are available on TPO systems we install. Workmanship warranties are included with all Morris Renovations projects.
