We have been fighting a small drip running down the inside of the window in our dinning room slide. I thought I had the leak fixed when I re-caulked all of the screw heads.
It rained about a month ago and the very slow drip started again. It's supposed to rain again in a couple days, so I got up on the slide roof and really looked things over and found this:
Not a great caulk job and when I started tugging a bit at the caulk, it wasn't adhered properly.
Some of the caulk was already separated or was very easy to separate.
Another leaker in the corner where the caulk didn't adhere correctly:
Some of the caulk peeled away easily along the roof to frame interface.
A couple close-ups of the cleaned interface:
This caulk is the runniest caulk I've ever used. That's why they call it "Self leveling lap sealant". Frankly I've never seen anything quite like it, but this stuff really leaves a nice wide and thick puddle. This is a much better roof sealant than the thicker caulks that leave a bead.
I re-caulked another place where there was a patch that had been glued on and had a tiny bead of thick caulk. This sure looks way better.
The factory used a thick bead caulk and you can see the results. This is the Ziollo caulk I used. It's way expensive, but the way this caulk spreads and levels, I will never use a bead caulk on my RV roof again.
Fixed slide roof water leak
The kitchen slide in our 5th wheel leaked whenever it rained hard. Just a small amount around the window, but a leak nonetheless. We had it back at the factory for our one year check up and I explained where the leak was and when it would happen. They re-caulked the seam on the slide top and...
