I am a structural engineer, but I did no math. Not the cheapest but I think it's the strongest of the options. Now the wall can span the piers on its own. Non-typical fix: Clad the ridge wall with 3/8 ply turning it into a shear wall. Standard fix: If the joists are hangered to the beams it would be easy enough to run a triple joist below the wall, provided there is room to maneuver in the crawl space. Effectively reduces the span of the ridge board and makes it continuous, earning it the honorary title of "beam". Something needs to support the ridge to eliminate the need for ties.Ĭheap, easy, and probably good enough: Triple up the stud in the center of the wall over your beam that runs perpendicular to the ridge. I would assume that the joists then span parallel to the wall, and there may or may not be one directly underneath it. From another comment you said that the addition is on helical piers with three beams running perpendicular to the ridge/wall. The wall would serve the same purpose as a ridge beam provided there was adequate support below the wall. Collar ties are necessary to prevent separation of the roof at the ridge due to wind uplift. H2.5A hurricane ties are made from 18-gauge galvanized or stainless steel to prevent rusting and corrosion and ensure durability. These ties offer a continuous load path by which the load can travel from the roof to the wall plates. Looks like a ridge board, not a ridge beam (would need to be deeper, probably LVL for Ontario snow). Unlike the first option, this hurricane tie works on one side of a rafter or truss for moderate wind protection.
