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 ????

I'm trying to put a couple simple shelves in out garage. We have brackets for the piece of wood that will be the shelf. Each bracket ( L bracket ) has to holes at the top for screws and one at the bottom. We used the stuf finder to find the wood behind the sheet rock. Problem is the first hole catches fine into the wood, but when I try to do the second hole, there is never anything behind the sheet rock. I don't feel secure only using one hole at the top of the bracket and the one at the bottom. I'm really not sure what to do. Thank you for any help.
