Flat Roof Systems

Flat and low-slope roofs are common on Chicago's commercial buildings, garages, additions, and multi-unit properties. Because these roofs shed water more slowly than pitched roofs, the membrane, seams, and flashing details matter enormously. Perez Roofing & Masonry Inc. installs, repairs, and maintains flat roof systems built to hold up against Chicago's freeze-thaw cycles, heavy rain, and wind.

Membrane Systems We Work With

TPO Roofing — installed using hot-air welding equipment for precise, durable seams and improved energy efficiency.
EPDM Roofing — a synthetic rubber membrane suited to Chicago's flat-roof buildings.
Modified Bitumen Roofing — torch-applied layers for long-lasting, weather-resistant protection.
Roof Coating Applications — applied with professional spray equipment to extend membrane life and improve efficiency.

Inspection, Detection, and Repair

Infrared Roof Moisture Scanning — finds hidden moisture pockets before they lead to structural damage.
Drone Roof Inspections — provides a full aerial view of a flat roof's condition without added foot traffic.
Moisture Meters — digital readings pinpoint leak sources for targeted repair work.
Sheet Metal Flashing Fabrication — custom flashing seals edges, valleys, and roof penetrations against water intrusion.

Francisco Perez, owner of Perez Roofing & Masonry Inc., leads the licensed crew handling flat roof installations and repairs across Chicago, working from foot-secure setups using certified fall protection and safety systems on every job.
