How to pop roof hinge back in?

Pictures say it all. My roof hinge has popped on one side of the camper and the upper corner of the front edge appears to be twisted from one side of the camper to the other. I did some detective work and it seems like this happened when the roof iced over in the open position last December in AK. Seems like a major safety issue, though I have been driving around not knowing that it’s broken since at least January. Any ideas how to fix this? Is this a known issue? GFC hasn’t replied to my message in ~10 business days, their form says expect 5 days.
