so we have had a leak in our new addition for a while now. we had thought we had solved the problem with some decisive measures but alas we have not. during a rain the water is pushed down the roof with some force. during a snow the water moves slow as it is just melting a slow drip.thus moving one drip at a time down the back of our siding. then behind the sheathing and on to my hardwood floor. i have no way of fixing this in this weather so it's just a waiting game.... water torture at it's best.
