Our Commercial Roofing Process
Commercial Roof Assessment
Before we recommend anything, we inspect everything. Membrane, seams, flashings, drains, penetrations, parapet walls, and rooftop equipment curbs. Core samples test for trapped moisture in the insulation. Honest assessment. No scare tactics.
Detailed Proposal
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.
Expert Crew
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
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.
