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. Marengo Roofing & Maintenance has the training and equipment to handle all of it across Marengo.
Our Commercial Roofing Process
Building Inspection
Our inspector walks your commercial roof and documents every issue: ponding areas, seam failures, flashing deterioration, clogged drains, and UV damage. Photos and measurements provided in a report you can share with your property manager or ownership.
Project Proposal
Your proposal includes material specifications, installation method, warranty terms, project timeline, and total cost. We itemize everything and explain why we're recommending the specific system for your building.
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 & Maintenance
Final roof inspection with photo documentation. Warranty paperwork provided. We recommend an annual maintenance plan to catch issues early and maintain warranty compliance.

About Our Marengo Commercial Roofing Services
Ponding water is the number one cause of commercial roof failure. Water that doesn't drain within 48 hours degrades the membrane and insulation underneath. Marengo Roofing & Maintenance installs tapered insulation systems that create positive drainage to scuppers, drains, or roof edges, minimum quarter-inch per foot slope.
Multi-family properties need roofing contractors who understand occupied buildings. Leak repairs are emergencies when water is in someone's apartment. Marengo Roofing & Maintenance prioritizes multi-family emergency calls and schedules planned work during reasonable hours.
