Flat Roofing Expertise You Can Count On

Showalter installs and services a range of high-performing flat roof systems, each selected and installed based on what’s best for your building.

TPO Systems

TPO is our specialty, and one of the most popular flat roofing materials in Chicagoland. We install it daily, replacing older EPDM systems and delivering clean, energy-efficient, and fully-welded membranes built to last.

EPDM Solutions

We’ve seen it all when it comes to EPDM. Whether it’s a full replacement or a seam repair, our team knows how to keep these rubber roofs performing and when it’s time to upgrade to a better system.

Insulation Solutions

Showalter provides ISO board insulation and tapered systems designed to improve drainage and energy efficiency. We’ll recommend the right insulation strategy based on your roof’s structure, history, and moisture levels.
