Hip-Roof Framing Made Easier
Measure from the rafter's bottom edge for exact layout.
Synopsis: North Carolina builder John Carroll dissects the process of building a hip roof and discusses his technique for rethinking this complicated piece of construction. Using the roof of a small outbuilding as an example, Carroll first locates the six king common rafters, then uses a table of rafter multipliers to determine the common-rafter lengths. He then determines the run and length of the hip rafters and jack rafters. Full-color illustrations accompany the article, highlighting Carroll’s hip-roof process.

The process became a whole lot easier for me when I realized that the primary challenge in building a hip roof is one of layout, not math. And the key to layout is to know exactly where to begin and end measurements.
In my approach, all the measurements are along the bottom edge of…
