What We Inspect
A proper commercial roof inspection goes beyond a visual walk. We probe membrane seams, take core samples to check insulation saturation, test drains for proper function, and examine every penetration, parapet, and edge detail — the areas where 90% of leaks originate.

What the Inspection Covers
Membrane Condition Assessment
Visual and probe inspection of all field seams, lap joints, and membrane surface for splits, blisters, open seams, granule loss, or UV degradation.
Flashing & Detail Inspection
Every parapet, curb, penetration, drain, scupper, and edge termination inspected for sealant failure, flashing separation, or moisture intrusion pathways.
Core Sampling
Representative core samples taken to verify insulation type, condition, and moisture saturation — the only reliable way to assess hidden moisture in the roof assembly.
Drainage Evaluation
All primary and overflow drains tested for flow rate, leaf guard condition, and proper slope. Ponding water areas documented and measured.
