Hip Roof Pitch Factors

Valley hip factor.

Hip roof pitch factors. You just have to go online and there you can search this. This way the pitch of the roof and the slope of the roof can be measured. The roof of your home is built to specific measuring standards according to the type of roof that is used. For example if you measure 4 inches the pitch of your roof is 4 12.

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 slope of the roof provides the rise and the run to be plugged into the equation. This will give you the rise over run or pitch. Even a dormer can represent a common hip roof pitch.

One of these measuring standards applies to the degree of slope that exists between the eaves outside edges of the roof and the ridge top most center of the roof. The hip and valley factor varies according to the slope of the roof as shown in the table below. The higher the slope the steeper it is. Divide the rise by the run the run is 12.

A roof pitch of 4 in 12 4 12 has a rise of 4 and a run of 12. This roof slope factor table also consists of hip and valley factors to measure the possible hips and valleys. Find the square root of the result. Length of the rafter.

The length of the rafters can also be determined while determining the slope. You can easily find roof pitch factor chart online from where you can take help in calculating pitch factor for your roof.
