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. Onekama Roofing & Maintenance has been installing flat roofs in Onekama for 15 years. We know what works and what doesn't in MI's climate.
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
Free Evaluation
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.
System Recommendation
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
Our flat roof crew installs per manufacturer specifications and NRCA guidelines. TPO seams hot-air welded and probe-tested. Modified bitumen torch-applied in two plies. EPDM fully adhered with proper lap adhesive. Tapered insulation installed to create positive drainage.
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.
