In this video we cover how to brace a conventionally framed roof and why it is important to do so. Then nail the king rafters in place against the ridge board. Measure the length of one of your rafters and mark the rafter at its midpoint. See saw miter and blade angle settings.

Hip roof framing rafter cut angle template diagram if using a circular saw or compound miter saw set saw bevel angle to 45 to obtain creeper and hip side angles. The hips are in red common rafters yellow and for hips to work on a square roof like above each member is equal. If the wall plates are all square of equal lengths then the hipped rafters would form a pyramid shape like the picture above normally a roof is rectangle and there are more yellow common rafters. Hip rafters are simply called hips and are shown here as brown.

However since there is some load transfer with these members the code requires a nominal 2 thickness and bracing to a load bearing partition at the upper end or to be designed as a beam with proper supports. Nail one rafter on each side of the hip roof to brace the ridge board in place. Bracing for roofs less than 6 6m wide on detached or staggered stepped buildings. There are 6 of these rafters on every hip roof.

With the saw bevel angle set to 45 cutting hips and creepers at the plumb cut angle will produce correct side angles. If we consider the rectangular shape of most buildings then hip roofs will be constructed with two triangular sides and two trapezoidal sides. King common rafters are the common rafters closest to the hip rafters. If you see sagging rafters recommend stabilization by a qualified contractor.

Hip roofs are constructed with four rafters that usually meet on a ridge board that is situated at the middle portion of the roof. You will learn some great tricks for using braces to keep.

Span for the main rafters measure from outside of wall to outside of wall. Tap a small nail into the side of the rafter at that point. Stabilization typically involves installation of a purlin system. Diagonal rafter bracing should be approximately 45 to the rafters on plan.

The hip roof framing calculator returns the value of the main rafter the side rafter the length of the hip the height of the knee wall and the lengths of the jack rafters. Applicable to all trussed rafter roofs unless rigid sarking such as timber boarding or plywood is used. Whereas in the case of square buildings hip roofs are more commonly pointed toward the top portion while forming a pyramid like structure.
