Which term refers to the distance along the rafter from the outside edge of the top plate to the center line of the ridge?

The term that defines the distance along the rafter from the outside edge of the top plate to the center line of the ridge is referred to as "Line Length." This measurement is crucial in roofing and carpentry as it helps builders determine the correct length of rafters needed for a specific roof design. The line length offers a direct measurement that accounts for the slope of the roof, allowing for accurate cuts and proper alignment.

Understanding this term is vital for anyone involved in construction, as it ensures that structural integrity is maintained in the roofing system. The use of line length is especially important when calculating other roofing parameters, such as pitch and total rise, which relate to different aspects of the roof's geometry but do not specifically describe the distance referenced in the question.
