Hip Valley Roof

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.

Hip valley roof. Hip roofs are thus much more resistant to wind damage than gable roofs. 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. A hip and valley roof may be part of an irregular structure. Now outline the biggest rectangle inside the building layout.

The hip and valley roof design can go up against different style that when nitty gritty right can ooze a cutting edge feel. This breaks the line of the hip hence the origin of the term broken back. 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. 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.

79 is represented the plan of a hip and valley roof. Find the square root of the result. 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. A valley rafterforms a depression in the roof instead of a hip.

Plan of hip and valley roof. Hip roofs have no large flat or slab sided ends to catch wind and are inherently much more stable than gable roofs. 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. Hip roof also called hipped roof roof that slopes upward from all sides of a structure having no vertical ends.

The degree of such an angle is referred to as the hip bevel. Hip and valley roof framing is no so complex as compared to hip roof framing procedures. First of all you need to design the layout of building. 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.

The hip is the external angle at which adjacent sloping sides of a roof meet. Here roofs are constructed with an angle of 90 degrees. This type of roof is also called broken back hip and valley roof because the main hips are intconeected by the rafter of gables on one side and the rafter of the valley on the other. Such buildings may have more than four hips in the roofs and they form valleys at the inside corners.

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.
