Deck Roofing System

The Foundation Beneath Your Deck

A roof deck is only as good as the roofing membrane beneath it. Chicago's freeze-thaw cycles, driving rains, and standing water from melted snow demand a roofing system that performs flawlessly under your walkable surface. Unlike sloped roofs that shed water quickly, flat roof decks trap moisture if the membrane fails—and that failure can go unnoticed until water reaches interior finishes. The roofing system isn't just a building component; it's the invisible barrier that makes your outdoor living space possible.

We specify and install roofing membranes purpose-built for occupied rooftops: TPO for reflective cool-roof performance, modified bitumen for heavy foot traffic areas, and EPDM where proven longevity matters most. Every detail counts—heat-welded seams that test at over 100 pounds per inch tensile strength, fully-adhered applications that eliminate wind uplift risks, and flashing systems integrated seamlessly where the roof meets walls, curbs, and penetrations. We've seen too many deck projects fail because the roofing was treated as an afterthought.

When you work with us, the roofing and deck systems are designed together from day one. We coordinate with structural engineers on load requirements, install proper drainage slopes before the membrane goes down, and detail every termination point before your deck framing begins. The result is a weatherproof assembly backed by manufacturer warranties and our own craftsmanship guarantee—a roof deck system that handles Chicago weather while you enjoy the view.
