Has anyone ever seen this done before? You can see where the builder added nail plates where he notched the rafters. Looks like he miscalculated on the bird’s mouth. This was on both sides. Brand new townhome.
Jason, that looks like a fold-down roof for a Modular Home and they also missed the rafter with staple attachment of the roof sheathing.
The builder didn’t “add” anything - this is an engineered truss system. Hinged gusset plates are used so that the trusses can be delivered to the building site.
