Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Oswego Roofing & Maintenance has the training and equipment to handle all of it across Oswego.
TPO is our most-installed commercial membrane in Oswego. White reflective surface for energy efficiency, hot-air welded seams that are stronger than the membrane itself, and 15-20 year manufacturer warranties. We install 60-mil and 80-mil systems, fully adhered or mechanically attached, over polyiso insulation.
Our Commercial Roofing Process
Commercial Roof Assessment
Before we recommend anything, we inspect everything. Membrane, seams, flashings, drains, penetrations, parapet walls, and rooftop equipment curbs. Core samples test for trapped moisture in the insulation. Honest assessment. No scare tactics.
Project Proposal
Commercial roofing proposals from Oswego Roofing & Maintenance include detailed specs, phasing plan if applicable, tenant coordination plan, and a realistic timeline. One number, no surprises.
Commercial Installation
Our commercial crew installs per manufacturer specifications and NRCA guidelines. Hot-air welded TPO seams tested with a probe at every joint. Flashing details custom-fabricated for your building's penetrations. Insulation installed to achieve minimum R-value per code.
Warranty Activation
Final roof inspection with photo documentation. Warranty paperwork provided. We recommend an annual maintenance plan to catch issues early and maintain warranty compliance.
