Overhang – This is the part of the roof that extends beyond the exterior wall of the home.Span – This is based on the total footprint of the house and the distance between two exterior walls.If you think back to your early geometry classes, you might remember that the pitch of a triangle is the rise over the run. Pitch – This is the incline of the roof.Rafter Length (with rise, run, post height, birdsmouth) Roof Measurement.
