Deck ledger board failure - GIF

[odd one]

I call out improper ledger attachments all the time on home inspections. It is scarry how many poorly built decks are out there. I will typically find something incorrect with a deck or wooden porch on new construction 20-25% of the time. Deck screws in hangers or no hangers or ledgers typically seems to be the most common deficiency on homeowner/handyman built decks.
