My garage has a 17' 2x8 ridge beam. The roof is a V, lowest in the center, with 2x4 rafters nailed to the sides of this ridge piece.
At some point the roof drain clogged, the roof turned into a swimming pool, and this ridge board/beam cracked/tore in the middle. (As I understand it, this failure means that it is a "beam"--a load-bearing piece?) Someone "fixed" it by propping the ridge up with a 4x6 post wedged under the damaged point.
I'd like to replace the post with a more permanent fix. I assume some kind of sistering/bracing would be the standard approach? It would not be extremely hard to put a full-length sister of the same size next to it, sitting on added jack studs. But if that approach is overkill, it would be nice to not have to wrestle with shortening all of the rafters on one side and removing all of those metal joist hangers.
EDIT: tweaked wording and added pics. The bottom one is an attempt to show the damage to the wood. There is a similar "tear" in the top half of the beam on the other side of it--sort of a mirror image.
