I have porch attached to the exterior wall of the house roof is pitched away from the house:
I am in the process of gutting it and want a vaulted ceiling. There are ceiling joists running perpendicular to the rafters (i.e. from side to side, parallel with wall of house). Because the roof is not pitched in that direction, i assume these do not form any part of the structure and can be safely removed. Is this a correct assumption?
