## Gable Roof Span

How does one calculate the span of a Gable roof when determining the size of rafters to use. Is each plane considered a span or is the span the distance across the entire width of the roof? It seems to me that a gable roof is stronger than a shed roof since the rafters support eachother.

Actually, the rafters do not support each other... unless you use a ridge BEAM (not ridge 'board'). Then, in effect, you have two shed roofs butted together at the top.
