Slide Out Seal Failure??

The rubber wiper that wipes the roof of the slide as it goes in and out is the seal I am speaking of. The way I see it if it is laying with its wiping edge down on the roof of the slide it along with the side wipers prevents rain water from running back into the inside of the coaches outer wall where it could potentially encounter the wooden structure or inside coach floor and cause damage. I am aware of the weather seal on the inside of the slide out flange that seals against the inside of the slide out opening as well as the rubber bead seal that seals the outside of the slide out when the slide is closed they are not effected but I view both the wiper seal and the inside flange seal as a system that work together to prevent leaks when the slide is out/open. My dealer is about 110 miles away so I have emailed them a photo and am awaiting their reply.
