Noise , from roof glass ? help

I have a 2012. Over the past 6 months I get a noise has progressively developed, ( 2/3 rattle 1/3 squeak squeaky rattle ) It occurs over any bumps in the road. Very difficult to pin down but seems to come from the roof toward rear. Has anyone else encountered this. I have a very good body shop man. With me driving he got in back and seemed to agree it was likely roof glass/frame interface. He said he would have to remove the head liner to begin search. Has anyone else experienced this ?
Brought the car to dealer to check for like 5 times. Among them i think one time they took the whole roof off to reapply the adhesive. The other 4 times they just re-torqued the roof to spec.
Rattle/squeak still exists, but the rate is less now.
Took it to the dealer, they removed the roof lining and retorqued everything. I haven't heard a noise from my roof for at least 6 months.

thanks all. My suspicions were correct. I assume these are bolts connecting sunroof frame to body ? Would locktite be a no no ? Hate to go through this again.

Have you asked your dealer what they would charge to fix it for you?
I asked them to quote to remove the roof liner and torque the roof. It was under $200 for the job, so I was ok to pay that.
It's been a year now I think and it's still fine.
thanks
