Thanks - does this count as flashed properly? Sorry to hear about yoursLooks good, I hope you flashed the new deck, better then the old one.
It is unfortunately, no longer a surprise to find that kind of damage behind unflashed ledger boards. We will finally start working on a deck that we have spent the last 2 weeks repairing damage from the first one. Think 8x10 beam, holding up part of the 2nd story, rotten for 3' from one bearing end.
