small wrinkle on roof of slide

[Bgjvan]

Hello
See the pic attached/below. Noticed a small wrinkle of the rubber roof of the slide. The roof of slide is solid and no soft spots are present even under the wrinkle.
Is this cosmetic or should be a concern???

The material will do that from time to time as the temperatures changes. No reason for concern and considered normal. My TT has had wrinkles since new and have never had a problem.

Our slides roof looks like that too. Probably they shouldn't but believe it is more cosmetic then something that should be a major concern.

As long as the 'wrinkle' doesn't interfere with the function/seal of the horizontal wiper seal it should be ok.., but worth inspecting once in awhile.

Also, with the slide extended confirm that the outer vertical and horizontal seals overlap at the slide roof corner(s) so water is directed away.
