## All Roof Systems

[ Modified Bitumen SBS Modified bitumen (SBS) stands out for being rubber-modified asphalt sheets that stay flexible in cold and resist Chicago freeze-thaw cracking. Compare options](https://commercialrooferschicago.com/roof-systems/modified-bitumen-sbs) [ Silicone Roof Coating Silicone coating comes into play as a seamless, ponding-resistant restoration coating that reflects heat and renews a weathered roof. Scope the roof](https://commercialrooferschicago.com/roof-systems/silicone-roof-coating) [ Built-Up Asphalt We specify built-up asphalt (BUR)—multi-ply asphalt-and-aggregate roofs valued for redundancy and still found on many older decks—when the building fits its strengths. Plan access](https://commercialrooferschicago.com/roof-systems/built-up-asphalt) [ White EPDM For demanding low-slope work, White EPDM provides a reflective rubber membrane combining EPDM's cold flexibility with cool-roof heat rejection. Protect operations](https://commercialrooferschicago.com/roof-systems/white-epdm) [ Spray Polyurethane Foam We reach for spray polyurethane foam (SPF) when a roof needs a monolithic insulate-and-waterproof system that self-flashes irregular rooftop conditions. Plan access](https://commercialrooferschicago.com/roof-systems/spray-polyurethane-foam) [ TPO 60 Mil Picture 60-mil TPO as a reflective single-ply membrane that balances cost and durability for typical commercial fields, matched to the deck and budget. Document conditions](https://commercialrooferschicago.com/roof-systems/tpo-60-mil) [ Fleeceback TPO Fleeceback TPO earns its place as a fabric-backed thermoplastic membrane offering extra puncture resistance and strong adhesion. Document conditions](https://commercialrooferschicago.com/roof-systems/fleeceback-tpo) [ TPO 80 Mil 80-mil TPO works best where you need a heavier-gauge reflective membrane chosen for high-traffic roofs and longer warranty intent. Control water](https://commercialrooferschicago.com/roof-systems/tpo-80-mil) [ KEE Roof Systems Consider KEE membrane when you want a thermoplastic system with high chemical resistance for grease- and exhaust-heavy roofs. Control water](https://commercialrooferschicago.com/roof-systems/kee-roof-systems) [ Modified Bitumen APP On the right roof, modified bitumen (APP) delivers torch-applied asphalt sheets with a tough plastic-modified surface for low-slope durability. Protect operations](https://commercialrooferschicago.com/roof-systems/modified-bitumen-app) [ PVC Roof Systems Where Chicago weather is the test, PVC membrane offers heat-welded thermoplastic with excellent chemical resistance and reliable welded seams. Schedule the work](https://commercialrooferschicago.com/roof-systems/pvc-roof-systems) [ Black EPDM Black EPDM is a proven rubber membrane that stays flexible through deep Chicago cold but absorbs summer heat. Scope the roof](https://commercialrooferschicago.com/roof-systems/black-epdm)
