Continuing on from part 3.
The ridge board runs the length of the building and provides support for the tops of the rafters helping the whole roof structure work together as a system.
Ridge beam sizing is based on the span of the beam between supports and the amount of roof load supported by the beam.
The loads on the ridge beam are carried by vertical posts at the beam ends down through the building structural walls to the building foundation.
