Slideout seal problem

[dshind]

We rv fultime.We live in a 36ck3.Had a problem with rain soaking my carpet on the kitchen slide.Looked on top and discovered the slideout seal that runs along the top of the slide in several places wasn't even touching the roof.Talked to Kent at Doubletree and he said it probably shrunk....probably from the sun.I told him the inside seal( under the outside one) was probably a half inch from touching the top of slide.He said probably shrunk from sun. I asked how the sun gets through the outside one to do that.He said heat transfer.I think this was a bad design and it's CYA time.By the way my side is not out of align and goes in and out great.Anyone have any ideas on a fix?
Thanks
