Pre-Inspection Checklist for Commercial Property Owners
Use this checklist before calling for on-site service to help your team gather the right details.

Walk the property and note visible issues such as missing or loose fasteners, lifted seams, blistering, ponding water, sagging sections, and deteriorated flashing around vents, Commercial roofing skylights, and HVAC units. Photograph problem areas and record measurements of any standing water after rainfall. Also check interior signs like water stains, damp insulation, ceiling discoloration, or rust trails. Make a list of roof penetrations and document their condition, since these points often drive moisture intrusion.
What to Verify During a Roof Inspection
A strong inspection focuses on both surface conditions and underlying performance. Confirm that the contractor inspects membranes and seams, evaluates drainage pathways, and checks the condition of flashing and counterflashing. Ask for an assessment of roof edges, parapets, and coping systems, since these areas are vulnerable to wind-driven rain. Ensure the inspector looks at HVAC curb openings, roof hatches, Free roof inspections and skylight flashing for gaps or compromised sealants. Verify that they check insulation condition, membrane attachment, and signs of thermal expansion. For flat and low-slope systems, confirm they evaluate slope, scuppers, gutters, and downspouts for blockage. Request a clear explanation of findings, along with recommended next steps and priority items.
Maintenance and Repair Priorities to Reduce Risk
After inspection, prioritize actions that prevent water from entering and that extend roof lifespan. Start with immediate repairs for active leaks, open seams, and failing flashing. Address drainage problems next by clearing debris, repairing clogged scuppers, and correcting water flow to reduce ponding. Replace or reseal deteriorated roof penetrations and ensure all transitions—such as around vents and equipment—are properly sealed. Schedule routine maintenance to monitor minor wear before it becomes structural damage. Keep records of completed work, materials used, and maintenance outcomes to support future planning and smoother warranty discussions.
