Flat Roof Replacement in Passaic & Bergen County
Expert flat roof replacement using TPO, EPDM, or modified bitumen systems. We handle tear-off, insulation, drainage solutions, and waterproof installation.
About This Service
Flat roof replacement requires specialized knowledge that differs significantly from pitched roofing. Drainage, membrane selection, insulation, and flashing details all demand precision because water does not shed off a flat roof the way it does on a slope. A flat roof done wrong leads to ponding, leaks, and premature failure.
We install flat roofing systems using TPO, EPDM, and modified bitumen — each selected based on your building type, budget, and performance requirements. TPO offers excellent energy efficiency and weldable seams. EPDM provides proven long-term durability. Modified bitumen delivers a robust multi-layer system for demanding environments.
Every flat roof replacement includes a thorough inspection of the decking below. If we find rot, sagging, or structural damage, we repair or replace the affected sections before installing the new membrane. Proper insulation and vapor barriers are installed to prevent condensation and improve energy efficiency.

Flat Roof Replacement in Passaic & Bergen County FAQs
How long does a flat roof last?
TPO and EPDM systems typically last 20 to 30 years with proper installation and maintenance. Modified bitumen systems last 15 to 25 years. Lifespan depends on installation quality, drainage, and exposure conditions.
What causes ponding on flat roofs?
Ponding occurs when water collects and remains on the roof surface for more than 48 hours. Common causes include insufficient slope, clogged drains, structural sagging, or improper membrane installation. We engineer proper drainage during every flat roof replacement.
Can you add insulation during a flat roof replacement?
Yes. In fact, we recommend it. Adding rigid insulation during replacement improves energy efficiency and is often required to meet current NJ energy code. It also provides a smooth surface for the new membrane.
