I'm planning to attach a shed style roof to my house. It will be 13' wide and 10' deep!
I have two questions, to do with the ledger board!
The house wall is standard 2X4 construction. The wall is sheeted with 3/4" spruce material. Which is in turn covered with cedar lap siding. The last course of the siding at the soffit is a spruce 1X8.
I need to hang a 2X8 ledger board over top of the 1X8.
I was planning to bolt the ledger to the wall studs using 3/8X4 lag screws. [ledger=1 1/2", spruce 1X8=3/4, sheeting 3/4" for a total of 3"] I would have two lag screws per wall stud. The lags would penetrate the wall studs one inch.
The first question is the lag length adequate, the second being is it acceptable to mount the ledger over top of the existing 1X8 or does it have to be against the wall sheeting?
Hopefully I have explained this adequately!
I have to expect a snow load of 50 psf and and will be using 2X8 rafters supported by joist hangers on the ledger board.
This brings a 3rd question to mind. How many nails are required to fasten each hanger to the ledger board. They come with 6 holes on each side. Shall I use all six or would fewer be adequate?
