We own a vertical log home in the upper peninsula that was built i’m guessing in the early 1960’s. The home is approx 24×24 with a small front porch 8×12. The home currently has maybe a 6/12 pitch roof with rafters not trusses. We would like to remove the entire roof and replace it with 12/12 pitch attic trusses to gain another bedroom or two. Will the vertical log with the vertical grove and spline support this change? We have also replaced the original footings and three block high wall.
