Flat Roof Repair of a Commercial Building in Princeton, NJ
This project involved a complete replacement of the old roofing system on a commercial building in Princeton, New Jersey. The previous roof had leaks and poor drainage, which reduced the building’s energy efficiency and insulation. The main goal was to fully restore waterproofing, improve water runoff, and provide long-term protection for the structure.
Project Overview
For this flat roof repair, we selected a PVC roofing system — a durable and flexible material ideal for low-slope roofs. PVC offers exceptional resistance to UV rays, standing water, and temperature fluctuations, making it a popular alternative to traditional EPDM roofing systems. The membrane seams were heat-welded to ensure a completely watertight surface — a critical factor for commercial properties.
Work Stages
- Removal of the old roof. The existing roofing and insulation layers were fully removed to inspect the substrate and prepare the surface.
- Surface preparation. The base was cleaned and leveled to ensure strong adhesion for new materials.
- Installation of tapered insulation. A sloped insulation system was installed to direct water toward the drains and eliminate standing water.
- PVC membrane installation. A modern PVC membrane was laid, and all seams were heat-welded to create a seamless, monolithic surface.
- Final inspection and cleanup. The roof was inspected for leaks, proper flashing, and edge sealing before the site was cleaned and handed over to the client.

Project Results
After completion, the flat roof in Princeton, NJ became fully watertight and weather-resistant. The tapered insulation ensured proper water flow, eliminating the risk of puddles and leaks. The new PVC roofing system improved the building’s energy efficiency, reduced maintenance costs, and gave the roof a clean, uniform appearance.
