Do I need a top plate for rafters on a porch roof?
Question:I'm building a gable roof over a 10x26 porch with 6x6 corner posts. I have dual 2x8's running from the corner posts to the house. Do I need to run a top plate on top of the 2x8's for the rafters to sit on -- or can I just cut the bird's eye and have the rafters sit directly on the 2x8's on end. I'm told I need a top plate, but I don't understand the purpose of it in this case.
Answers:
If you're sure you have no code in your area, then I say let common sense rule. If you can't come up with a good reason for a top plate in your particular application, then go without it. That's what I would do.
You will need to contact your local building office to see what is called for in the building regulations.
