HOW IT WORKS
OUR 3-STEP COMMERCIAL METAL ROOFING PROCESS
Step 1: COMMERCIAL SITE INSPECTION & CORE SAMPLING
Our team performs core cuts, moisture surveys, and deck evaluations to verify existing insulation layers, structural integrity, and local code limits (including two-roof layer maximums).
Step 2: TAPERED DESIGN & SPECIFICATION REPORT
We deliver a detailed proposal with custom tapered insulation layouts for positive drainage, wind uplift calculations, membrane options (mil thicknesses), and transparent pricing tiers.
Step 3: PROFESSIONAL INSTALLATION & SIGN-OFF
Our safety-certified crews heat-weld seams and install flashings around all HVAC curbs and penetrations with minimal operational impact, culminating in final city and manufacturer warranty inspections.
