Commercial roofing is a different discipline from residential. Flat and low-slope systems (TPO, EPDM, PVC, modified bitumen, and built-up roofing) each have specific installation requirements and performance characteristics. Negaunee Roofing & Maintenance installs and repairs all of them across Negaunee.
We install every major commercial roofing system: TPO single-ply, EPDM rubber membrane, PVC for chemical-resistant applications, modified bitumen for high-traffic roofs, and built-up roofing for proven long-term performance. Material selection depends on your building, budget, and specific exposure conditions.
Our Commercial Roofing Process
Commercial Roof Assessment
We inspect the entire commercial roof: membrane condition, seam integrity, flashing details, penetration seals, drain function, and insulation condition. Core samples reveal moisture levels in the existing system. You receive a detailed written report.
Scope & Estimate
Commercial roofing proposals from Negaunee 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.
Final Inspection
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Negaunee Roofing & Maintenance.
