Chateau Citation Headliner

[Citation]

2010 Chateau Citation 29BG. Coach had suffered a water leak in roof and resulted in front ceiling vinyl covered panel being wrinkled. I removed the front overhead florescent light fixture and there is a thick foam between vinyl ceiling cover and roof. Has anyone had to replace the headliner vinyl covering and if so how does one remove the panel in order to work on it? I had one repair shop say the roof had to be removed first but I wrote to Thor and they said it doesn't need to be removed but is difficult to repair.

I took it to an automotive upholstery shop and they can recover it but they don't know how to remove the panel.



Any thoughts??

Thanks
