TPO Commercial Roofing in NJ — Reflective, Durable, Energy-Efficient

Modern TPO membranes typically last 20–30 years in NJ's climate when properly installed and maintained. Annual inspections to catch seam separation early, plus prompt repair of any punctures from rooftop equipment service, are the keys to reaching the upper end of that range.

For most NJ commercial buildings, TPO is the better default choice — better energy efficiency from the white reflective surface, heat-welded seams instead of taped, and a meaningfully cooler rooftop in summer. EPDM still wins on extreme cold-weather flexibility and on buildings with heavy foot traffic where membrane elasticity matters more than energy savings.

We tear off the existing roof to deck, inspect and replace any rotten decking, install rigid insulation board (typically 2–4 inches of polyiso depending on the energy-code target), then mechanically attach the TPO membrane through the insulation with proper fastening pattern. Seams are heat-welded, all penetrations get field-fabricated flashings, and parapets get full bonded membrane with metal counter-flashing.

Sometimes — TPO can go over an existing single layer of asphalt or built-up roofing with a cover board, but we strongly prefer full tear-off. Going over an existing roof hides moisture-trapped insulation underneath, traps drainage issues, and shortens the new roof's life. We'll evaluate your specific roof and tell you honestly which approach is right.
