OK I hope I don't get flamed to bad here. Just went to do a estimate for attic finish/remodel. It's all good to go which is rare but collar ties running the length of the attic, as usual I'm fighting for head room in a attic job and would love to see 'em go. Rafters 16 oc, 2 x 6. 8/12 pitch with a ridge board I'd date it about 60's. The ties look to me like a more recent addition with a couple of screws on each end holding them up and cut off square every 4'. I know the safe play is to just leave 'em be but I'm fighting headroom and would make a world of difference. So I'm asking you framers can I lose the collar ties?
