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. Walnut Hill Roofing & Maintenance installs and repairs all of them across Walnut Hill.
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
We present options when they exist: repair vs. replace, TPO vs. PVC, 15-year vs. 20-year warranty. Each option is priced so you can make an informed decision based on your budget and building plans.
Expert Crew
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
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Walnut Hill Roofing & Maintenance.
