Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Big Bay Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Big Bay.
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 MI UV exposure. It's the toughest flat roof membrane for everyday abuse.
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.
Your Options
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.
Professional 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
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.

Why Choose Big Bay Roofing & Maintenance for Flat Roofing?
Drainage Solutions
We solve ponding water with tapered insulation systems. Minimum quarter-inch per foot slope to drains or edges. Ponding is the number one flat roof killer. We eliminate it.
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.
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.
Electronic Leak Detection
We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.
