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. Riverdale Roofing & Maintenance has been installing flat roofs in Riverdale for 20 years. We know what works and what doesn't in IL's climate.
Our Flat Roofing Process
Flat Roof Inspection
Our inspector checks every detail: ponding areas, seam separations, flashing failures, clogged drains, UV degradation, and blistering. Core samples test insulation moisture content. You get photos and an honest assessment.
Your Options
Based on inspection findings, we recommend the right solution: targeted repair, a coating system, or full replacement. Each option is priced with material specs, warranty terms, and expected lifespan.
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.
Warranty & Drainage Test
After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

Why Choose Riverdale Roofing & Maintenance for Flat Roofing?
Specialized Flat Roof Crew
Flat roofing requires different skills and equipment than sloped roofing. Our flat roof crew does this work every week, hot-air welders, torch kits, and adhesive systems are their daily tools.
20+ Years Flat Roof Experience
Riverdale Roofing & Maintenance has been installing and repairing flat roofs in Riverdale for 20 years. Residential flat sections, commercial buildings, and everything in between.
Electronic Leak Detection
We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.
Core Sampling & Testing
Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.
About Our Riverdale 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.
