Slide toppers drooping, cause rain to puddle on top of slide. Also allows water to seep into coach. Stuck in Washington this winter and full timing in the wet. Wondering if any body has had experience with water proofing your canvas slide toppers? Thinking about trying flex seal. Any suggestions or ideas are appreciated. Thanks

Did you check Youtube.com for DIY waterproofing fabric?

I use a long piece of styrofoam insulation stood on edge. Pink grade is more durable.

Depending upon how the topper is installed you probably won't be able to stop the puddling. Actually I can't help but wonder if the leaking isn't the best option as it eliminates the water and topper sag?

Highly Highly suggest your resolve the leaks into the coach. Water damage sneaks up on folks and is very expensive. Toppers can help but in themselves don't stop water leaks.

Whats the topper made of? Then you can waterproof it. Best to try to stretch it toghter if you can. See how it attaches. Sometimes ots not a bad idea to set the camper up a little off level for dranage. Not sure how this translates to yours, but it helped the pup, and the TT i have now. ( this was mostly to direct ac run off)

You seem to have two separate problems. You can get rid of the puddling with a beach ball or something similar under the middle of the topper. The leak may be a whole different story. It could be a bad top seal on the slide or even a misaligned slide when all that weight is on it. Get rid of the puddling first and then the leak problem may go away or at least be easier to diagnose. A porous slide topper should not be any more of a problem than not having a topper.

Water on the roof of the slide should not come in
That is a seal problem or a levelling problem
Or both together, you want/need that water to run off, not collect against the seal and seep inside,
Bad weather I usually keep the slide in, but if its out that side will be ever so slightly lower than the otherside


I can explain it to you.
But I Can Not understand it for you !

While Slide rooms should NOT leak, if you have a older Monaco Motorhome, (they came with slide toppers), having a leaking or removed slide topper will usually cause a leak inside. A operative and not sagging slide topper keeps probably 90% of the water from getting on top the slide room roof and makes less water to contac the upper slide room seal. The best way to prevent sagging is to build a 1 inch PVC tent pole system(don't glue the pieces). You slide it in the middle of the slide fabric and cause a slight "A" . This causes the water to run to the upper awning rail mount and run off and the other to run off the outer edge of the slide room. Doug
