I first noticed the water in the light fixture above the bathroom sink. The area around the hole seemed dry. There was also water on the floor under the area where the roof membrane was cut, so some water made its way down the wall as well as across the ceiling. I could cut a hole in the area behind the lower cabinet to take a look and to vent the area inside the wall. Thanks for the suggestion about the speaker hole. I may drop a speaker and look through there. There is also a large access hole to the "attic" through the vent on the roof for the refrigerator.
