An RTU curb gasket is torn, skipped, or leaking at a corner
A curb gasket failure can become a roof leak into the supply/return opening. Do not hide it with outside caulk only; document it and get the unit reseated/re-gasketed by the approved method.
The RTU curb gasket at [corner/location] is torn/missing/folded. I checked the curb and unit alignment. Do you want us to lift/reseat and replace gasket per the approved detail before we tie this in?
Watch out
Do not rely on exterior caulk to fix a failed curb gasket that is trapped under the RTU.
Check
Inspect all curb corners before the crane unhooks when possible.
Check for torn, stretched, dirty, missing, or folded gasket.
Look for curb damage, plenum opening exposure, roof membrane issues, and unit alignment.
Document the condition with photos before weather hits or the unit is fully tied in.
Coordinate safe lifting/jacking and roofer/equipment requirements before repair.
