Flat roofing is what separates experienced contractors from general roofers. The materials are different, the installation methods are different, and the failure points are different. Oak Brook Roofing & Maintenance has been installing flat roofs in Oak Brook for 23 years. We know what works and what doesn't in IL's climate.
Our Flat Roofing Process
Flat Roof Inspection
We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.
Detailed Proposal
Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.
Membrane Installation
Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.
Final Inspection
Final roof inspection with drainage verification. Warranty paperwork provided. We recommend a maintenance plan to keep your flat roof performing and your warranty valid for its full term.

About Our Oak Brook Flat Roofing Services
Modified bitumen is our recommendation for residential flat roofs and high-traffic commercial applications. Two-ply torch-applied SBS system with a granulated cap sheet handles foot traffic, thermal cycling, and IL UV exposure. It's the toughest flat roof membrane for everyday abuse.
Flat roof leaks usually happen at penetrations, seams, or flashing details, not in the middle of the membrane. We locate the source with electronic leak detection or flood testing, repair it properly, and address the root cause. If the membrane is shot, we recommend replacement, not a band-aid.
