The air conditioner is located above this and I have removed the ac and resealed it, but didn’t remedy the problem. It is a slow leak because it has to rain continuously for a day before we see any indication of water. Has anyone had this issue? Where did you find the leak? Is there a way to determine where the leak is without removing roof panels?
See picture to see where leak is occuring

Your A/C seal is leaking into the return air duct. The seal between your roof and AC needs to replaced or compressed by tightening the AC mounting bolts. It will only leak when it rains.
