I have an outdoor patio off by second-floor master bedroom. This patio has a slate floor. There is a leak from rain water on this patio floor into the wall in the kitchen below the patio. I have had a roofer seal the seam between the patio and the wall with a real good rubber caulk. The leak persists. I have narrowed it to about a half a square foot in one corner of the patio. I don't think the water is getting through the rubber seal that was just put down and I can't see any cracks or holes in the slate, although there are a couple of seams where several pieces of the slate come together and these are very narrow seams. They don't visibly look like water would flow through them. I think there must be micro channels that the water is getting through and seeping into the wall. I'm wondering if there is a sealant of some kind that would flow into those micro channels and seal itself to prevent water from flowing through. I'm working with slate on the floor Your thoughts and suggestions are appreciated!
