Adding depth to rafters
I have an old garage that is being converted into living space. The second floor has 2X6 rafters 24" on center 16 ' long with a 10 12 pitch. The building inspector stated I have to build them out because of insulation requirements. I thought about butting up to the 2X6's a 2x12 or using Sampson strongtie RC1.56 Ripper Clip or using plywood gussets and adding a 2X10 on top of the 2x6. By adding on top the depth would be greater then the 2x12 but much more work. Any opinions or has anyone done something different?
