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. Vandalia Roofing & Maintenance installs and repairs all of them across Vandalia.
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. Vandalia Roofing & Maintenance installs tapered insulation systems that create positive drainage to scuppers, drains, or roof edges, minimum quarter-inch per foot slope.
Our Commercial Roofing Process
Free Assessment
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.
Scope & Estimate
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
Manufacturer warranty registered upon completion, 15-20 year coverage depending on system and build-up. We offer maintenance contracts to keep your warranty valid and your roof performing for its full life span.
