I have a Moen shower faucet that is six years old(copper sweated plumbing). My wife noticed water dripping profusely from the downstairs ceiling during my shower. The screws holding the face plate were...
Try removing the handle, then the face plate. With a flashlight handy, check inside the wall around the valve to see if you see any leaks. Then, try the valve by pulling the stem (may need a plier to grab this). Keep checking inside the wall. Next, try the shower, and again watch in the hole you have. You may find that the connection(s) to the valve is/are leaking, particularly at the top of the valve where the shower pipe heads up the wall. Or, it may be that the shower head's arm is leaking somewhere above. If you only see water dripping down from above, try the flashlight with a small make-up mirror to see if you can see where it's coming from. Sometimes the pressure in the shower head builds up from the flow restrictor, or the head's spray holes may need cleaning out (try soaking the head in a solution of CLR [stands for Calcium, Lime, Rust] available at most home improvement/ hardware stores). Sometimes the shower arm (the bent 1/2" diameter pipe that the shower head mounts to) isn't fastened in tightly enough. A good trick to help here is to wrap the threads with teflon tape, then apply teflon paste also. Wrap the tape clockwise around the threads so that it doesn't unwrap when you screw the pipe back into the fitting in the wall. Also, make sure the threads in the fitting in the wall are cleaned out, and don't let any debris contaminate the new teflon paste as you slip it back through the hole in the wall. If you find that the pipe out of the top of the valve is leaking, I recommend you call the plumber. He/she can likely fix it without taking the wall apart.
