Sagging Headliner

[Moxxi]

The DW & I were checking out a 2008 Itasca Suncruiser 38T.

We noticed that the ceiling liner had this one place where it was sagging.

The salesman said that this was caused by the humidity.

Regardless of why this happens, is this something that is easily fixed? Is this something that is a common problem?

The salesman said that, in order to fix it, you had to pull down the entire liner.

Surely there has to be a better solution to fix this problem.

Sorry for the time lag.
I could not send a photo from my phone, so I had to fire up my laptop.

The liner is usually glued to a foam backer which in turn is glued to the lauan.

Foam perishes (heat) so headliner falls away from the foam and it is just about impossible to get a lasting adhesion to crumbling foam so difficult to make a good repair.

In this case you could probably pull the cover strip out a bit and pusg the edge under a bit to tighten it up and then push the cover strip back.

If it gets worse then you can just let it all sag and then use screws with snap caps to screw up into the lauan in a cushion pattern which looks OK.

Same thing happened in our 2006 Meridian. It started with the slides, then before long, multiple patches all over the roof.
If you are looking at Winnebago/Itasca, check the roof to sidewall caulking has been maintained.
Ours required checking every six months, and is a necessity to avoid leaks or worse.

The same thing happened in our '06 Itasca. I managed to pull the divider strip where I could open up the affected area and spray some 3M adhesive behind the bubble and reattach the cloth.
