This will not fix your problem, but I would yank that valance off. That will give you better observation in your quest.
I took down the valance and blind and the corner hole where one of the screws hold in the valance was wet. I stuck a q-tip and paper towel in the hole and after about an hour, the paper towel was soaked. I replaced the q-tip and towel several times over the weekend and each time it was wet. I am really concerned that there was so much water still in the ceiling of the slide.
I calked and sealed everything I could find on the slide roof and also calked around all the slide topper screws. If it still leaks at this point, I don't know what else to do.
