The depth of a heel cut is typically 1 1/2 inches. This measurement is crucial in roofing construction, specifically for the design and installation of rafters. A heel cut refers to a notch made at the end of a rafter where it meets the top plate of the wall. The correct depth ensures that the rafter sits properly on the wall, allowing for proper load distribution and maintaining the structural integrity of the roof system. Using the specified depth of 1 1/2 inches helps achieve consistent rafter height and ensures that the overhang and roof pitch are as intended, impacting both aesthetics and function. Understanding this measurement is fundamental for those working in construction and roofing to ensure a correctly framed structure.
