Hip Roof Rafter Bracing

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.

Hip roof rafter bracing. Measure the length of one of your rafters and mark the rafter at its midpoint. Bracing for roofs less than 6 6m wide on detached or staggered stepped buildings. Step 2 hang a plumb bob from the nail and mark the point where it touches the joist below the rafter using a pencil. See saw miter and blade angle settings.

Tap a small nail into the side of the rafter at that point. If you see sagging rafters recommend stabilization by a qualified contractor. Similarly hip and valley rafters provide the point of connection for roof rafters framed at angles. You will learn some great tricks for using braces to keep.

Select the following information by using the drop downs to enter values in feet and inches. 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 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. Hip roofs have hip rafters which are oriented diagonally to the ridge and outside walls.

There are 6 of these rafters on every hip roof. Bracing for larger roofs. Diagonal rafter bracing should be approximately 45 to the rafters on plan. The hips are in red common rafters yellow and for hips to work on a square roof like above each member is equal.

In this video we cover how to brace a conventionally framed roof and why it is important to do so. Stabilization typically involves installation of a purlin system. Whereas in the case of square buildings hip roofs are more commonly pointed toward the top portion while forming a pyramid like structure. 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 roofs are constructed with four rafters that usually meet on a ridge board that is situated at the middle portion of the roof. Then nail the king rafters in place against the ridge board. Bracing for roofs that are approximately square. 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. Applicable to all trussed rafter roofs unless rigid sarking such as timber boarding or plywood is used. With the saw bevel angle set to 45 cutting hips and creepers at the plumb cut angle will produce correct side angles.
