Is it wet now... take a screw driver and punch a hole up into it to determine if you have pooled water in it...let it drain.
See if it drys out with no rain...water can soak into insulation and relwease slowly onto to of drywall. If it drys out it's likely the roof.
If it doesn't dry out in several days, I'd try not using each fixture one at a time for a day or two.....watching to see if you get leakage from a tub, or a sink, or a toilet etc.
When I've had roof leaks involved, and weather dry and accomadating, I litterly haul a hose up and statring at lower portion of suspected leak area, flood each successive area for a couple of hours, then up to next area, untill I get the leak.
I just use o concrete block to hold the hose`, I don't sit on the roof.
Remember, that water seems to flow in strange manners (always downhill) but it follows rafters and studs and can be pretty far when it pools from the actual leak.
