Rooftop curb counter-flashing is letting rain under the unit
Water behind curb flashing is a stop-and-fix condition. Verify the roofing/detail overlap, counter-flashing, sealant, and who owns the repair before the leak damages the building.
Water is getting behind the counter-flashing at [unit/location]. I traced the leak path and checked the roof detail. Do you want roofing/GC involved, or should we remake the flashing per the approved curb detail?
Watch out
Do not bury a known roof leak under exterior caulk without correcting the flashing path.
Check
Find where water enters: top lip, corners, fasteners, seams, curb base, membrane termination, or unit base.
Check approved roof curb/flashing detail and roofing scope.
Look for short flashing, missing hem, bad corner, loose fasteners, or failed sealant.
Protect the opening from rain while the fix is coordinated.
Photo before/after because roof leaks become blame magnets.
