With wooden deck ledger's attached to wood framing, the ledger always gets flashed, preventing water from entering behind the ledger and causing rot.
For the first time, I've come across a ledger fastened to a wall that is concrete above and below, with no additional siding planned. What is the protocol for flashing in such a situation?
I assume that it is still desirable to prevent water from getting behind in the letter and freezing and expanding, but there is nothing to lap over the flashing above it.
