Hello and Welcome -
This is MIKE - Im sorry to see you have had a wait.
Usually this is down to something thats got into the mechanism for the roof - check for debris / litter on the hinges etc..
Check also the back panel - above the boot area sometimes those panels come out of place and cause a jamb.
I don't think at this stage its much so try that first as above.
Let me know how you go..and / or let me know if you need anything further on this..~~~>>>>>>~ Meanwhile - Please do click on the "Exc / Ok rating" for me at this time.. Thank you in advance for that . ..Note that you can get back to me anytime at all after doing the rating - it doesn't close you out -- Best Rgds, MIKE.
