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. Gwinn Roofing & Maintenance has been installing flat roofs in Gwinn for 12 years. We know what works and what doesn't in MI's climate.
PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in Gwinn, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Our Flat Roofing Process
Membrane Assessment
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
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
Flat roof installation requires specialized equipment and training. Our crew uses calibrated hot-air welders for TPO and PVC, torching equipment for modified bitumen, and proper adhesive systems for EPDM. Every seam, flashing, and penetration detail gets individual attention.
Final Inspection
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.
