Broken sunroof, or something else?

[WRWhit93]

Hey guys, a couple of days ago I started hearing something rolling around. At first I thought it was something in my trunk just going back and forth, but have determined it's coming from in the roof. It sounds like a fairly small item in the area that bumps down behind the sunroof (where the sunroof goes when it's open.) Any idea what it is? Anyone gone through this? Thanks in advance.

i had a small rock in mine that jammed the sunroof and wouldnt let it open(i got into the track). dont ask me how a rock got up in there but yeah...
