The other type of Water is Liquid form. We know it as Rain, or a plumbing leak. It can also be Condensation.
If it rains we expects our roofing materials and our exterior materials to shed the water and drain somewhere, just not in my yard or house. You would expect that someone would be handling this, and all looks well on the outside, but did they get it mostly flashed or fully flashed. We talked that Water always wins, so what flashing does, is allows water to come in from critical areas, and redirecting it out, back where we want it, outside.
Brick and mortar are very pourous and soak water straight through behind the brick. It then does what? Soaks into the frame of your home, unless we give it a way out, like Weep Holes. We have to put some type of water barrier, not vapor barrier, on the exterior walls to direct that water down to a way back out though weep holes. Siding, and Stuccos have the same issues and must have methods to drain, when water gets behind them.
Windows and Doors are critical openings that have to be properly flashed in order to keep water from getting to the frame of your home and rotting the wood. I am telling you that many builders do not understand this, and the subs that install these products only install what the builder tells them to install. Some codes are now coming on strong to re-educate builders back to standards of yesteryear when Builders understood flashing. Yesteryear Builders however didn't understand Vapor.
