My covered porch has seen some better days. The 2x10 joists are rotted on top causing the wood on top to sag. The 2x10 is notched and inserted into the brick on both sides. I have a feeling that this was done while the house was being built. This makes it impossible to replace them without changing something and all the joists need to be replaced.
My questions is: what is the preferred method for doing this type of repair?
Would I attach a ledger board to the house and notch in the joists on the other side or put up two ledger boards. Perhaps there is some trick or system that I'm not aware of.
