Top quarter rust

Has anyone had this happen to there cabby? The roof is twisted up on its own by the looks of it and it's only this side

reasonably common, need to get the hood off the shell round the back and check how bad it is

What do I do? Take roof all the way off and get someone to repair the rust?

What's made the roof roll up? The other side hasn't

if you check out the hood repair guide what you need to do is get the C pillar fabric off the bottom of the parcel shelf supports and lift it out the top, then you can gain access to the rear hood tensioning strap

once thats loose you can tug the material out of the lip to see just how bad the rot is, it may be its weakened the lip enough that its bent in on that side, or its just not been fitted quite right. you wont know till you look
