I refuse to build a deck attached to any house except a second story one. I make all mine free standing. That way there's 0 chance of wall damage.
If you insist on doing yours that way then there needs to be OSB sheathing running past the top of the foundation, then covered with Storm and Ice shield over that, not just tar paper. Attach 12" long pieces of vinyl lumber every 4' along the new ledger board to act as a spacer and through bolt or at least use long lag bolts through the ledger and spacer into the bottom mud sill (also know as the foundation plate. Then water water can run down the wall and not lay on top of the decks ledger board.
Never have the decking material come in direct contact with the siding.
Never have the siding making full contact with the decking.
Never have the deck any higher the 4" min. below any door openings or it will take out the subflooring.
