My roof in my ED is sagging around the middle.

The roof is immaculate so is there a way to make it just not sag again instead of buying whole new lining?

my roof lining is sagging also has so for the last 12months, got quoted $80 for a new one

Take it to your local retrimmer and ask them... It's a pretty common problem so i'm guessing they will be able to answer your question...

normal E-Series drama not much much you can do except get a retrimmer to fit a new lining

the foam layer behind the cloth breaks down after 10-13 years,all cars with glued cloth to card board backing,get a upholster to replace it,or diy,buy the cloth and spray cans glue,work up the length and trim off,see how old one fits, note you have to clean very well all the foam to make it flat and neat----messy
