Looking for answer to a question about attic ventilation. If you have seen my pictures under the topic "after the Storm" you know I am in the process of doing a lot of repairs. And I am attempting to improve things about this house. One of the problems (I thought) was water (or snow) coming in the top of the windows when it would rain. (The snow a problem after it started melting.)
Have you ever experienced horizontal rain (or snow)? You know it is pouring down rain and the wind is whipping along faster than most people drive. This mostly happens around here with a wind from the north. Wind blowing, raining, and in a bit water would be dripping down inside all the north windows of the house. Keep that in mind.... ALL OF THEM.
So after the storm we pulled all the damaged siding off the house and removed the windows. I noticed they were well caulked (All of them were). I didn't see any way for water to get around them. We are talking a lot of water when it rains or when the snow melts.
Here is my other conclusion. The soffits on the house has more holes in it than this picture I found...
And I am wondering about the possibility of the wind creating a vacuum on the south side of the house and sucking in the horizontal rain/snow through the holes on the north side. It then deposits the water behind that first board where it then goes down into the wall and drips in the windows. These are not my house just some pictures I found to illustrate.
I know I know. If I am correct that means this also has been happening inside the wall where there are no windows.
So I am wondering, down here in the south where it doesn't get all that cold and is dry most of the time, I could go with less ventilation and rig it so the horizontal rains can't get in..... right?
