The trusses rested on beams that extended perpendicularly from the house to the end of the roof. And by beam I mean one 2x4, twelve feet long. I decided to sister a 2x6, twelve feet long, to the original beam. I had to reconfigure a joist hangar to attach one end to the ledger board on the house (after and before)
This is where I attached it.
Then then I slotted in one end of the sister-beam.
And I was halfway there. Well, a quarter of the way, since I had to do the same on the other side.
