Your commercial roof is protecting your inventory, your equipment, your employees, and your revenue. A leak doesn't just damage the building. It shuts down operations. North Sandwich Roofing & Maintenance provides commercial roofing services that keep North Sandwich businesses covered and dry.
Our Commercial Roofing Process
Building Inspection
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.
Detailed Proposal
Commercial roofing proposals from North Sandwich Roofing & Maintenance include detailed specs, phasing plan if applicable, tenant coordination plan, and a realistic timeline. One number, no surprises.
Commercial Installation
Factory-trained crews using proper equipment, hot-air welders for TPO/PVC, torch equipment for modified bitumen, and adhesive systems for EPDM. Every seam, flashing, and penetration detail inspected before we leave.
Final Inspection
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 North Sandwich Commercial Roofing Services
TPO is our most-installed commercial membrane in North Sandwich. 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. North Sandwich Roofing & Maintenance prioritizes multi-family emergency calls and schedules planned work during reasonable hours.
