I have a wall in my living room that goes directly up to the dormer and includes the window. I am getting water coming down inside the wall. It only tends to happen when we have blowing rain. I have caulked all around the window and I don't believe it is the problem. THe sill doesn't show any water damage. The leak usually comes down directly above the left hand side corner of the dormer, every once in a while it's on the other side. I had some guys out that pulled the vinyl siding off and flashed the corners higher (didn't make sense to me).
To make a long story short. I plan to dig in to it myself. I feel like the corner is the problem and I was going to install something like this on both corner. I would really appreciate anyone's help that has gone through this or fixed it. I really want a water tight seal. It's very upsetting having water coming in every time we get a good rain.
I have done some reading as well and seen some people use step flashing along the side is that something I should consider as well? I want to do this right. Also, I'm not sure how or where exactly to use ice and water shield. ANy help would be greatly appreciated. IF you have any pictures that would be a HUGE help. Thanks in advance for any advice.
I also found this article. Is this how I should do it?
