** roof help **

[SKOOSH1970]

Hi all, the roof on my 2003 2.7 has started to sag a little under the glass rear window, on investigation it seems that the double sided tape that's used to attach the fabric to the frame seems to have detached. Has anyone any experience of a repair to this potential problem. The roof is in good condition and there are no signs of improper folding and she's still waterproof, just like to address the problem before it potentially gets worse.

Thanks in advance.
