TPO Roofing Systems

TPO membrane is a single-ply roofing material heat-welded at the seams to form one continuous, watertight surface. Its reflective white surface helps flat roofs manage heat, while the welded seams stand up to Chicago's freeze-thaw cycles and sudden temperature swings. Property owners typically turn to TPO when installing a new flat roof or replacing an aging membrane that has started to fail at the seams or flashing points.

Why TPO Fits Flat Roofs

  • Heat-Welded Seams — Fused seams create a single membrane layer instead of separate overlapping sheets, reducing points where water can work its way in.
  • Energy-Reflective Surface — The membrane's light-colored surface reflects sunlight rather than absorbing it.
  • Compatible Roof Details — TPO installations pair with proper flashing and scupper systems to keep water moving off the roof edges instead of collecting near seams.

Supporting the Installation

Before and after a TPO membrane goes down, drone roof inspections and infrared moisture scanning help confirm the deck and existing layers are sound, so the new membrane goes over a dry, stable base rather than trapped moisture.
