Good morning everyone!
Long time reader first post. I hope you all can give me some insight so I can stop worrying about this project. As you can see from the picture I removed a wood deck from the area. You can still see the ledger board which I believe is installed incorrectly. I am going to remove that board and then I want to install vinyl siding to weatherize the area for the winter (next spring I am going to build a patio and then have someone come out to build the steps down to it). My question is: Do I need to install some sort of vapor barrier before I install the vinyl siding? If so what type of product do I need and where/how do I tie it in with whatever is below the rest of the vinyl siding? I peaked under the siding to the left and it doesn’t look like there is any type of vapor barrier under the places already covered by siding.
