If it only leaks after the snow starts melting its probably your flashing or what is known as a snow dam (the reason for snow angels or snow birds on old fashioned roofs).

For a hundred bucks you could go to the Wal Mart and get a dining canopy which will provide a lovely covering over your bed. Add one citronella candle by the bed, and you should be able to screw your "Significant Other" into a coma, what with the gentle rain on the canopy and all. And when it runs down to the lower floors, those occupants will be the one to complaint about two or three noises; the dripping, the squeals, and the mattress squeaks.
