Commercial Roofing

Commercial buildings in Chicago typically call for flat or low-slope roofing systems designed to handle heavy snow loads, ponding water, and temperature swings across large surface areas. Perez Roofing & Masonry Inc. works with building owners and property managers on flat roof installations, repairs, and coatings suited to warehouses, retail spaces, and multi-unit properties. Francisco Perez, owner, oversees the crew on commercial projects alongside the residential and masonry work the company has handled since his father founded it in 1990.
