Lumber strength?

Lumber strength?

I am building a sunroom. Question: excluding the cost difference, is there any disadvantage to using cedar dimensional lumber to that of spruce? Does cedar have the same 'strength'?

Also, I will be attaching the sunroom from the main wall of the house by running rafters out about 8'. The header board I put along the house will support 2x4 rafters. I have thought of using a 2x6 along the house that will be fastened into the studs of the outside wall. Can I fasten this header (maybe it is called a runner?) with 3.5" nails? Should I use lag screws?

Thanks

I don't see anything wrong with any of the proposals you mention - but I'd check the local building code to be certain your proposal meets standard.

Personally, I would lag screw the ledge board into the existing frame.

For your information, spruce is stronger then cedar. Use a 2x6 as your ledger board, and use lag screws. Good Luck
