Feel a little silly asking this, but is it okay for mud-on-J to end at a butt joint, or should I remove it and re-install so it bridges the joint and the J bead joints fall in the center of the sheet? Drywall installers did the entire garage this way, and I have a couple days to fix it if necessary. Also, do I need to use a special (meaning fire retardant) caulk to seal around the chimney where it meets the sheetrock, or can I use clear silicone? Thanks in advance.

hello i have a flat roof ceiling and i bought this place with it . now i need to fix it some how with out having to replace the entire roof structure . who ever built this add on room did not do it right . the 2x4's span 11'6" NOT good. there starting to sag and hence got a leak now. i can not brice it up from inside as this is a living room area.. i was thinking maybe a beam across the room to support this crazy roof untill a few years down the road when i can maybe get it replaced the right way. the room spans 11'6" X 16' the 2x4's run 11'6" so i need the beam to run 16'. now for the problem of that.. head room is 10 inches and drops to about 5" or 6 " but i think i can get away with a beam in the middle but would have to cut the 2x4's so the beam could be placed right against the roof then the 2x4's would have to be attached to that beam. i know the whole entire roof must come off at some point in time and get fixed right. but thats gunna have to wait a few years. no money for that expense. so now what ta do with this mess ????
