I am remodeling a 1943 1&1/2 story upstairs. It has kneewalls that I have been told are not loadbearing (by a buddy who is a relatively new contractor) but they appear to me to be supporting my roof joists which consist of 2 joined 2"x6"x12's. The knee wall is located at the top end of the lower joist. Ideally I would like to remove the knee wall altogether if possible, they do overlap about 3'. If necessary can the knee wall be moved to the lower end of the top joist or can I add a header where the knee wall is now? There should be a picture in my gallery
