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. Shannon Roofing & Maintenance installs and repairs all of them across Shannon.

About Our Shannon Commercial Roofing Services
TPO is our most-installed commercial membrane in Shannon. 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.
Multi-family properties need roofing contractors who understand occupied buildings. Leak repairs are emergencies when water is in someone's apartment. Shannon Roofing & Maintenance prioritizes multi-family emergency calls and schedules planned work during reasonable hours.
