I had a skylite leak in the shower that rusted out the screws in the trim just front of the shower and 1/2 of one in the bedroom. Factory used expanding rivets, not good. Thru the road shaking they tore up the foam. In the bath I have installed a couple of plastic drywall mounting screws into the foam coated with silicone glue, then used the accompaning screws to attach metal bracket. I still need a couple more since the expanding rivets ate up the foam, I will use expanding foam to fill in the voids.
The internal skylight shell needed fixing as the wood the screws bit into was rotted. I used short pieces of sheet metal pushed into the foam halfway up over the screw holes, then used longer screws to attach.
The bedroom piece I am either going with the expanding foam and drywall anchors, or I may try inserting a thin piece of sheet metal up into the area and twisting 90 degrees.
Also, it is more than likely the water intrusion is not condensation, but a deteriorating gasket between the fan motor and the platform it is attached to, if you have the same units I do, where the fan blows out the top of the unit. I get water dripping inside during a heavy rain. Remove your schroud and look at the way the angle support funnels the water toward the motor shaft.
Best of luck.
I bought new shock gaskets and motor bearings and will try to repair soon. In New Orleans, showers everyday.
Meantime I run the rear unit on hi fan whenever heavy rain is forecast.
