Describe the leak
Find the Source of a Commercial Roof Leak
Commercial roof leaks are rarely directly above the stain. Water travels along decking, insulation, and structural members before dripping — sometimes 10-20 feet from the actual source. Symptom-based diagnosis helps narrow down where to look.
#
Common Leak Sources by Symptom
Leaks near HVAC curbs or penetrations suggest flashing failure. Roof penetrations are the #1 leak source in commercial buildings. Check sealant, flashing, and curb condition.
Leaks near edges or parapets indicate perimeter flashing issues, base flashing deterioration, or coping joint failures.
Leaks in the middle of the roof may point to membrane damage (punctures, seam failures), ponding water degradation, or drain failures.
Leaks after heavy wind suggest wind uplift damage, blown-off flashing, or debris punctures.
Leaks with ponding water present indicate drainage problems. Standing water accelerates membrane degradation and can overwhelm seams.
#
Inspection Approach
Start at the stain location and work back to find the entry point. Check upstream areas, penetrations, and flashings. Core samples can reveal wet insulation even when the membrane looks intact.
Document findings with photos and measurements — especially if warranty or insurance claims are involved.
