Hip Valley Roof

Hip roof also called hipped roof roof that slopes upward from all sides of a structure having no vertical ends.

Hip valley roof.

Measure the distance between the angled hip rafter and the top of the wall at 20 in 51 cm increments and cut jack rafters to fit. Here roofs are constructed with an angle of 90 degrees. A hip rafter is called for only when framing a hip roof but a valley rafter is needed on both hip and gable roofs whenever roof planes intersect. Find the square root of the result.

Plan of hip and valley roof. The hip and valley factor varies according to the slope of the roof as shown in the table below. Now draw the centerlines for all rectangles that are formed inside. The hip and valley roof design can go up against different style that when nitty gritty right can ooze a cutting edge feel.

The degree of such an angle is referred to as the hip bevel. Such buildings may have more than four hips in the roofs and they form valleys at the inside corners. Depending on the size of the roof most hip roofs will have 4 6 short jack rafters that are spaced out every 20 inches 51 cm between the hip rafters and the king common rafters. The triangular sloping surface formed by hips that meet at a roof s ridge is called a hip end.

Main features hip and valley roof design first off the hip and valley roof design is an extremely basic direct and utilitarian design every single current trademark. For any roof slope expressed as x in 12 rise in run the hip and valley factor is determined by finding the square root of rise run 2. A hip roof on a varied plan h denotes a hip v denotes a valley a hip roof is self bracing requiring less diagonal bracing than a gable roof. Hip roofs are thus much more resistant to wind damage than gable roofs.

Now outline the biggest rectangle inside the building layout. A valley rafterforms a depression in the roof instead of a hip. Like the hip rafter it extends diago nally from the top plate to the ridge. Divide the rise by the run the run is 12.

Hip roofs have no large flat or slab sided ends to catch wind and are inherently much more stable than gable roofs. 79 is represented the plan of a hip and valley roof. Hip and valley roof framing is no so complex as compared to hip roof framing procedures. This form of a roof is frequently termed broken back hip and valley because the main hips are intersected by the common rafters of the gables from one side and the valley rafters from the other.

First of all you need to design the layout of building. This breaks the line of the hip hence the origin of the term broken back.
