What angle is a hip roof?

Parts of a Roof A basic, conventional roof consists of rafters, ceiling joists, and a ridge board, as shown in Figure 17-3. More complex roofs include other elements such as braces, valley rafters and jack rafters. (See Chapter 18, “Hip, Valley, and Jack Rafters.”)
What does a 6 12 pitch mean?
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge). There are two suggested ways to measure a roof pitch.
What kind of framing do you need for a hip roof?
Hip roofs can be generally framed into a large variety of sizes that can be T or L shaped and may need a more complex frame structure. Here, the roof is divided as well as structured into various parts and major points of connection falls between the ridges and rafters, so the central portion of the roof demands more accurate framing.
How are the rafters attached to a hip roof?
Attach the 6 king common rafters at the end of the ridge board. King common rafters keep the ridge board steady in place. Nail one rafter on each side of the hip roof to brace the ridge board in place. Then, nail the king rafters in place against the ridge board.
What’s the first step in building a hip roof?
The first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof. Place the 4-6 common rafters in their designated positions along the 2 longest walls, and nail them firmly to the wall with a nail gun.
How does a hip roof look like on a house?
A close up of the top of the above roof and how each rafter and hip would fit together with the ridge (shown in purple) would look like this (notice the red hip rafters are cut to a point); Hipped roofs are rarely square like the example above. The picture below shows the same roof, extended length ways with the addition of a ridge.
