What is the function of a ridge rafter?

The function of a ridge rafter is to provide structural support at the peak of the roof, serving as the central beam to which other rafters are attached. It runs along the topmost line of the roof, connecting the two slopes of the roof's framework. This rafter helps distribute the weight of the roof and maintains the overall structural integrity.

While one might think it runs parallel to an edge of the roof, the correct description would actually define its position as spanning between the ends of the two topmost rafters. The ridge rafter is crucial in establishing the roof's shape and directing how the weight is borne, influencing the overall design and stability of the roofing system.

The other options describe components related to roof framing but do not accurately portray the role of a ridge rafter. Options specifying functions that support or connect other rafters can mislead, as they imply a role that does not establish the ridge rafter's structural significance at the peak of the roof.
