TPO Roof Installation

TPO roof installation uses heat-welded membrane sheets to create a single, continuous seal across a flat or low-slope roof. The white or light-colored surface reflects sunlight rather than absorbing it, and the welded seams resist the wind, ice, and temperature swings that Chicago roofs face year-round. Property owners typically turn to TPO when an aging membrane is failing, a new roof deck needs a durable covering, or an older system is being replaced with something more energy-reflective.

What the Installation Involves

Membrane Welding — Heat-welded TPO seams are fused into one continuous, watertight surface rather than relying on adhesives alone.
Flashing & Scupper Detailing — Edges, drains, and penetrations are sealed so water is directed off the roof instead of collecting at vulnerable points.
Slope & Drainage Review — Low spots are addressed before installation so the finished membrane doesn't trap standing water.

Checking the Roof Before and After

Before a TPO system goes down, drone roof inspections give a full view of the existing surface without added foot traffic, and infrared moisture scanning identifies any trapped moisture in the deck that needs attention first. Fall protection and harness systems keep crews secured throughout the installation, and once the membrane is welded and sealed, the roof is left ready to handle Chicago's rain, snow, and shifting temperatures.
