Slide roof leak

[timjet]

One of the slides on our coach collects rainwater on the roof of the slide below the topper when it rains. Water then enters the coach at a corner on the slide roof that I have identified and will seal with silicone sealant.
My question is, should the topper prevent water from collecting on top of the metal roof of the slide when it rains? It's currently raining and I brought the slide in which of course stopped the leak. So is it normal for the metal roof of the slide to have water on it and should I be satisfied with just sealing the corner of the roof that leaks or should I investigate why the topper is allowing water to get to the metal roof?

Our slider has an electric lock at the top center & there is a drain that can get plugged. An then water leaks into the coach. To unplug there is a small hole on the outside top on the slide & using a long pipe cleaner I run it in & out cleaning out the hole. An Yes water can sometimes get under the topper, blowing rain, melting snow, very hard rain! Always some kinda of work to do.

The short answer is, slideouts should not leak to the inside even if water gets under the topper. That is based on three essential aspects of the slideout: 1) the slideout is fully deployed and tightly seated along all four sides; 2) the rubber seals are in good shape and secured properly; and, 3) the upper edge of the slideout where the vertical edge meets the roof, has a good seal.

With regard the the rubber seals, our Winnebago Ellipse had an improperly installed upper seal, meaning the seal was not correctly attached and left a gap for water to penetrate internally during heavy rain and strong winds. A new seal replacement remedied the issue.

With regard to the upper edge seal, the gally slide on our Winnebago Tour leaked anytime it rained. The water penetrated the roof of the slide and dripped down through the cabinets unto the sofa. Essentially that slide became a fair weather only feature until we located the problem. This had been a used coach when we bought it, and apparently at some point a person walked on the slideout and dimpled in the roof, of which broke the silicon-based roof seal that runs the length of the slideout. That required resealing that seam, not an easy task. It has to be done with the slide topper removed and lifting the external rubber flap. Ugh

No matter what you do, you are going to get some water on your slide out roof. After a heavy rain, or before I leave a campsite, I lower the left front of my MH (using the leveling jacks) and drain any water off the slideout. I then re-level, and bring the slideout in.

Thanks for all the replies. I found the seal on the roof of the slide at a corner had a small gap and was allowing rain to enter. I sealed that gap. I took a good look at all the seals on that slide and it appears that I will need to replace some of them. Does not look like an easy job.

One thing to remember, (never use silicone sealant) on your roof because if you try and apply a different sealant it will not stick.
This is what most use to seal there roofs and slides, works great.

Opps, too late, I'll sealed the leak yesterday. We had a hard rain last night with no leaks, guess I got it.

Short answer: NO.

The topper is a debris catcher and in no way intended to keep water out.
