Flat Roofing Services in Chicagoland

Flat and low-slope roofs face unique challenges in the Midwest. From freeze-thaw cycles and heavy snowfall in winter to blazing summer heat, Chicagoland properties require flat roofing systems that can handle extreme thermal expansion without cracking or leaking.



At Advanced Professional Roofing, Inc., we engineer, install, and maintain commercial-grade flat roofs designed to deliver long-term, watertight protection.

Single-Ply Membrane Systems (TPO & EPDM)

Single-ply membranes are the industry gold standard for modern commercial flat roofs and residential low-slope additions due to their lightweight flexibility and exceptional weather resistance.

TPO (Thermoplastic Polyolefin)

TPO is a bright white, heat-welded membrane that reflects up to 80% of the sun's ultraviolet rays. By significantly reducing heat absorption, TPO lowers interior cooling costs during humid Chicagoland summers while forming a seamless, monolithic bond at every seam.

  • Best For: Commercial buildings, retail spaces, and warehouses seeking energy savings.
  • Key Advantage: Highly resistant to punctures, chemicals, and UV degradation.

EPDM (Ethylene Propylene Diene Monomer)

Known as "rubber roofing," EPDM is an extremely durable synthetic rubber membrane engineered to withstand extreme thermal shock. It expands and contracts effortlessly during rapid Chicago temperature swings without tearing or losing elasticity.

  • Best For: Low-slope residential roofs, industrial structures, and high-wind exposure zones.
  • Key Advantage: Exceptional flexibility with a proven track record lasting 25 to 30+ years.

Heavy-Duty Bituminous & Torch-Down Roofing

For flat roofs subjected to frequent foot traffic, heavy mechanical equipment, or severe standing water risks, traditional multi-ply systems provide unparalleled structural puncture resistance.

Modified Bitumen Torch-Down Rubber Roofs

Modified bitumen combines asphalt with synthetic polymers to form a thick, rubberized sheet. During a torch-down installation, our experienced crews melt the asphalt layer directly onto the deck substrate, creating a fused, impenetrable waterproof seal.

  • Multi-Layered Protection: Incorporates fiberglass or polyester reinforcement layers to resist punctures and tearing.
  • Watertight Seams: Torch application welds seams into a continuous sheet, eliminating common entry points for ponding water.
  • All-Weather Performance: Built tough to handle ice dams, snow loads, and debris without degrading.

Seamless Elastomeric Roof Coatings & Restorations

A failing flat roof doesn't always require a costly, disruptive tear-off. If your current membrane is structurally sound but experiencing minor leaks or surface wear, fluid-applied coatings offer an economical restoration pathway.

Elastomeric & Silicone Roof Coatings

Applied as a liquid, elastomeric coatings cure into a seamless, flexible membrane that seals pinhole leaks, encapsulates rusted flashings, and creates a highly reflective top layer.

  • Extends Roof Lifespan: Adds 10 to 15+ years of operational life to your existing flat roof.
  • Cost-Effective: Avoids landfill disposal fees and labor costs associated with a complete tear-off.
  • Seamless Barrier: Eliminates every joint and seam across the entire roof surface.
