Cathedral ceiling - no collar ties-ok?
We recently moved into an 80 yr old home in Cleveland Oh. I'm going to begin finishing the attic (open rafters right now) and I plan to leave the cathedral ceiling, insulate and rock'- it.
The rafter height is 12' at the peak, and the floor is about 28'x28'. The rafter beams are 2x6's on 16" centers, toe nailed into a 1x6 at the ridge.
But there are no rafter ties, is that normal, is it ok to leave like that? or do I have to lose the cathedral and put them in? what about the 'lateral force/pressure pushing out on the exterior walls' thing?
(And they've never been removed, or at least there is absolutely zero signs that there were ever ties in place.)
