I’ve got a 60s era carport with a rotted post. It’s a low slope cantilevered roof about 20 feet long. It has two posts on each corner at the front, and the back is supported by the house.
The rotted post is a 2x4 sandwiched by 2x6s like an I beam.
The pier this rests on is perfectly sized for a 4x6. What holds me back from putting in a 4x6 is I don’t know about cutting a birds mouth into an existing beam, and the pier is not very level.
What do you all think? As built or how to sub in a bigger column?
