What Is TPO Roofing and Why Are South Bend Building Owners Switching to It?

TPO stands for thermoplastic polyolefin — a single-ply membrane that's taken over as one of the most popular flat roof systems on commercial buildings across northern Indiana. The white reflective surface bounces heat away from the building instead of absorbing it, which means real cooling savings during Indiana summers. NIPSCO and AEP rates keep climbing every year. A TPO upgrade on a poorly insulated building can cut summer cooling costs by 15–30%. That's not a marketing number — that's what building owners across Michiana are actually seeing on their utility bills after installation.

TPO vs. EPDM vs. Spray Foam — Which Flat Roof System Is Right for Your Building?

This is the question we get most from plant managers and facilities directors across the Ameriplex corridor and Mishawaka industrial zone. Here's the honest breakdown:

OPTION 1

TPO

Best for buildings where energy efficiency is a priority, where the existing deck is in solid shape, and where the owner wants a clean white membrane with heat-welded seams and strong puncture resistance. Ideal for distribution centers, light manufacturing, and medical office buildings in Granger and Mishawaka.

MOST POPULAR

EPDM

The workhorse. Better suited for older buildings with irregular penetrations, lower budgets, or situations where flexibility in cold temperatures matters more than reflectivity. Most of the 15–25 year old roofs in the South Bend industrial corridor are EPDM.

OPTION 3

Spray Foam

The right call when ponding water and low spots are the core problem. Spray foam fills the irregularities, adds R-value, and gets coated for a seamless waterproof surface. Conklin-certified spray foam systems are what we recommend when the drainage issue can't be solved any other way.
