Here is more detail on ledger board attachment to walls or other surfaces where debris and moisture may be trapped resulting in rot or deterioration. In this particular application a joist was installed parallel to the wall of the home which would mean it would be directly applied on top of the original ledger board. This is a case where ledger board spacers are used to allow fastening to the wall of the home with structural screws while also leaving a 1/2" gap to allow moisture to run away from the wall without introducing wood rot. Managing moisture flow away from the wall of the home and preventing the trapping of debris between the deck and the wall of the structure is extremely important and one of the top three problems that I find when inspecting homes.
