I'm having an attached patio built by a contractor. I am concerned about the quality of the construction. In particular the attachment of the patio joists to the house rafters. Instead of using a ledger board, our contractor has simply attached the patio joists to the rafters using nails. Is this safe?
Not very strong and certainly not as strong as if you had a ledger board.
Why not just have your contractor add a ledger board under the ends of the patio rafters? Tell him that's the way you want it and you want the ledger board lagged into the house.
You're the one buying so have it like you want it.
Good luck with your project!
