Commercial Retail Building

Project Overview

About This Project

This commercial retail building underwent full roof replacement after the existing system showed widespread deterioration beyond repair. The project involved complete removal of the existing roofing membrane and installation of a new TPO commercial roofing system designed for waterproof protection, improved insulation performance, and long-term durability. The primary objective was addressing active leaks, enhancing energy performance, and providing a long-term solution that supports daily commercial operations without disruption.

Initial Assessment

Conditions Found

  • Membrane shrinkage and seam separation across the roof field
  • Water pooling due to poor drainage slope
  • Surface cracking from prolonged UV exposure
  • Deteriorated flashing at all parapet walls
  • Multiple previous patch repairs no longer holding

What We Used

Materials

  • TPO (Thermoplastic Polyolefin) membrane
  • Rigid insulation boards
  • Heat-welded seaming materials
  • Parapet and penetration flashing components
  • Drain integration system

How It Was Done
