I got one for the Framing crew. My customer has a summer cottage by the creek (closer than he would like he found out recently.) At any rate , in an attempt to make it more like a 4 season home. He would like to re-frame the attic floor without removing the bedroom ceiling and add insulation etc. also going to need some drop down stairs in a new opening so headers and trimmers too, are needed. the roof is 10:12 without exploring to much further, I am assuming the rafters are about 16′ resting on the 1st floor top plate. the second floor has a knee wall. I THINK it is NOT load bearing. the ceiling consists of collar ties, sistered to the rafters, which are 24″ O.C. (kinda wide if you ask me) 2×8’s (but i’m no roof framer.) His question: can We nail a second collar tie , above the first 2×6 without disrupting the integrity of the rafters. He thinks this will allow him to add, more insulation and it is important to him, that he be able to walk on this as a service floor. And Of course storage. My concerns. # 1 ) the increased weight. being added to the entire roof. # 2 ) will adding all those nails to the new 2 x 6’s so close to the old color ties weaken the grain structure of the rafter . I wouldn’t feel so worried if he didn’t want to, put down plywood & store things up there. # 3 as it is now, someone cut thru the colar ties to add a drop down staircase, which to me would have been a no no. but of course it is in a convienent place. I think it would be better structurally, paralell to the collar ties. anybody tell me why I shouldn’t worry about that. Would a couple of solid trimmers replace the missng collar ties . Do you know what I mean. I would like to move it elsewhere. Any advice? when I have to think about it to much i usually don’t do it. Ease my mind. I need the money.
