What is included in roof framing plan?
The roof framing plan is similar to the roof plan but in addition to showing the shape of the structure and the outline of the roof, it also shows the size and direction of the framing members use to frame the roof.
What is the simplest roof framing plan?

Stick-framed roofs utilize individual rafters that span from the top of exterior walls to the ridge. Truss-framed roofs are built from triangular-shaped, pre-made truss units.
What is a roof truss what gives roof trusses their structural strength?
The queen post truss offers a reliable yet simple design that features a central post with a support lattice that can be used on any roof with less than a 10-yard span. Because of its simplicity, it’s easy to install.
