The term "total run" in roof framing is related to which aspect of a triangle?

In roof framing, the term "total run" refers to the horizontal distance from the center of the ridge (the peak of the roof) to the outside edge of the wall on one side. This measurement directly relates to the width of the base of the triangle formed by the roof structure.

When visualizing a triangle in the context of roof framing, the total run helps in determining the slope or pitch of the roof, as it represents half the width of the building that the roof is covering. It is a crucial measurement when calculating angles and ensuring the roof is properly supported and adorned.

In contrast, the other aspects of the triangle such as the height pertains to the vertical rise, the hypotenuse represents the slanted roof surface itself, and area involves a calculation that includes both base and height but is not directly linked to the total run measurement. Thus, the connection of total run to the width of the base clearly establishes its importance in roof framing practices.
