An alternative method for providing support up the
ridges of a hip set is for the truss manufacturer to
drop the flat top chord of the hip trusses by 1

and provide a special purlin frame (in red) for the
framing crew to drop in above the hip girder.
The frame fits in the plane of the front face of the
hip set, and provides additional rigidity to the roof
system. Nailing sheathing into the 2x4 flat studs is
also convenient.

Valley Set – A valley set is a group of trusses which
sit on top of other trusses in order to change the
way the roof looks. In the example below, without
valleys, we would have an empty "hole" in the roof
behind the girder. This would need either stick
framing, or a valley set.
