I have an addition that was desiged with a cathedral ceiling. Walls are 9' high, rafter length is around 14' from birds mouth to ridge and pitch of roof is 9/12. I have large beams 9' apart spaning from wall top to wall top to keep the walls plumb due to roof load. I have been wondering if I should put in additional collar beams to stregtnen the roof, but I rather not. Please offer any suggestions
