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. Zahl Roofing & Maintenance provides commercial roofing services that keep Zahl businesses covered and dry.
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. Zahl 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
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.
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.
Professional Installation
Installation phased to minimize disruption to your tenants and business operations. Debris containment, noise management, and clean work areas maintained throughout the project. Project manager on-site for every commercial installation.
Warranty Activation
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Zahl Roofing & Maintenance.
