Hi, I am in the process of converting my garage to living space and had a few questions about beefing up the existing roof rafters. I have 2615 rafters; the room is 28 ft wide and 15 feet from the top ridge beam to the floor. I thought about sintering 28ÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s to the rafters and beefing up the ridge beam by adding a 28 beam laminated together with a another 28 then carrying the load down to the floor on each end and also cross brace underneath the beam to the new 28 rafters. Also, I was going to add more cross bracing 2 ft down from the ridge beam so I can accommodate for my HVAC lines. I intend to sheetrock the ceiling w/Ãƒâ€šÃ‚Â½ and was wondering if this plan of mine would be more than enough support to the ceiling? Also, I will use metal strapping were all rafters meet to the top sill plate, which is supported by 8*16 block wall.
