The Basic Steps of Hip Roof Framing The Basic Steps of Hip Roof Framing

Hip roof framing is more complicated than that of a gable roof. Instead of 2 faces to the roof with a ridge board running the length of the structure, a hip roof has 4 sides. The ridge board is centered widthwise and lengthwise. Like the framing of any roof, there are some basic points to know in order to do it successfully.

Hip Roof Basics

The basic components of a hip roof are common rafters, hip rafters, end common rafters, jack rafters and the ridge board. Common rafters run perpendicular to the ridge the entire width of the structure. Hip rafters run at a 45 degree angle to both the sides of the roof and the common rafters, comprising the edges of the 4 faces. End common rafters run along the same line as the ridge from each end of the ridge board to the overhang. Lastly, jack rafters run parallel to the common rafters, only they become successively shorter because they intersect with the hip rafters.

Hip roofs are framed in a variety of sizes and can even be T- or L-shaped, requiring a more complicated frame. However the roof is structured and divided, the main points of contact are between the hip rafters and the ridge. The centering of the ridge is vital for accurate framing. Once these are in place, the common rafters, end common rafters and jack rafters can be properly set.
