Slide Toppers - waterproof?

Thanks for all the input guys. Obviously I need a new topper and to inspect the seal better. Water has collected behind the drivers seat. It looks like this has been an issue for a long time with this RV (It's new to me). The roof of the slide is not completely flat so water will pool on top and when you bring the slide in, the low spots don't get squeegee'd off. However it appears there is still some leaking with out retracting the slide. I'm going to take a better look today.

Our's ('08 Monaco) are obviously deteriorating, stretching out, and allowing water to pool in the toppers.
Last time I brought the kitchen slide out, I had water coming into the coach, dripping onto the kitchen counter.

New toppers are on my spring list.

I replaced two or my slide topper awnings with Tough Top Awnings and have been very pleased. Their material is heavier than my original and easier to clean. I would recommend them.

Even with a new slide topper, you will get some water on top of the slide during a blowing rain. Try raising the front or rear of the coach to make the water run off the slide, then re-level before retracting the slide. I also put an old towel on top of the slide to prevent any residual moisture from dripping down the front of the slide during braking. Don't forget to remove the towel before extending that slide again.

Thanks for all the input. I'm ordering a new topper from tough tops but am evaluating the slide seals as well. If I can order new seals at a reasonable price it seems like a good time to replace them while I have the topper off. After pulling the carpet out it's quite clear that this has leaked off and on for some time. I really want to put an end to the leak before I put new flooring in.

On my 99 Windsor I found a leak at where the inside flange (behind fascia) attached to the slide body. I used 5200 sealant at inside corner to fix. I found a new flipper seal at http://www.uni-grip.com/dealer_catalog.pdf
Make sure the seal flips. I added a non skid strip (1", not too rough, not sandpaper) around the perimeter about 4" from the inside to help the seal flip.
