(Sorry for the crosspost, I didn't know this group existed.)
I have a room that was added on to the back of my house. It's about
18 x 28 (feet) - a big whopping room. The outside of the room is
brick, with 2x4 framing inside the brick. Across the shorter
dimension of the room are 18' long 2x8's, 26" on center. There's a
normal shingled roof over top, it's sort of a shallow pitch.
What are the odds I can remove all the ceiling joists and open up the
room to have a cathedral ceiling ? Without everything falling down
that is ! The roof ridge runs parallel to the ceiling joists.
