I would like to build a Cedar patio cover / pergola. I need help with the beam size and material. (solid beam or 2 joists doubled up)
My patio area is 21'L x 11'W. I would like to cover as much as possible. what should I use for sufficient beam support for this length??? I was planning to use 2'x6'x12' joists, and 4"x6" posts (4 one per corner).
appriciate any help.
