About
Certified Master Installer of EPDM, TPO, PVC, and KEE membrane systems, DeMarco Inc. has delivered commercial roofing across Central Ohio for over 30 years. Headquartered in Columbus, OH, the company holds a General Contractors license and an A rating from the Better Business Bureau — credentials that matter to facility managers and property owners vetting vendors for complex, high-stakes projects. DeMarco's commercial portfolio spans schools, hospitals, hotels, office buildings, warehouses, and retail centers, with documented experience on projects ranging from single-story facilities to 50-story high-rises. That breadth of building-type coverage gives facility managers confidence that DeMarco can handle the full spectrum of low-slope and flat roof work common across Columbus's institutional, healthcare, and commercial real estate sectors. Core commercial services include roof replacement, roof repair, roof curb installation, metal roof repair, and metal coatings — giving building owners a single-source contractor for both membrane systems and metal roof assets. The team is a certified installer for manufacturers including Firestone, Carlisle, GAF, Johns Manville, and Tremco, supporting manufacturer warranty compliance on new installations and replacements. Beyond membrane work, DeMarco provides masonry repair, chimney repair, EIFS repair, caulking of control joints, and pitch pocket maintenance — services that extend the useful life of a roofing assembly and reduce moisture intrusion risk in aging commercial envelopes. Their roofing analysis and inspection services support budget planning and capital expenditure forecasting, a practical value-add for facility managers managing multi-year maintenance schedules. With three decades of local market experience and a general contracting license, DeMarco Inc. is a well-rounded commercial roofing partner for Columbus-area property managers seeking certified installation quality alongside broader building envelope expertise.
