Hip Roof With 2 Different Pitches

Blind valleys simplify framing.

Hip roof with 2 different pitches.

How to use the hip roof framing calculator. Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12. While the slope of the common rafters are expressed as x in 12 the slope of the hip and valley rafter on the same roof will be x in 16 97 so where two roof sections intersect to form a 90 angle a regular hip or valley and each roof. The pitch of the unequal hip rafter can be expressed in relation to either the main roof or the secondary roof.

But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons. The most common hip roof pitch ratios fall between 4 12 and 6 12 although variations occur based on factors such as snow rain and wind conditions which is because steeper hip roof pitch ratios allow for less accumulations of snow and rain on the roof and lower ratios provide less wind resistance. Select the following information by using the drop downs to enter values in feet and inches. 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.

Explore framing complexities that result when roofs of two different pitches intersect. To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. Discover 5 types of hip roofs plus 22 examples of many houses that incorporate all the different hipped roof styles. Learn more about off angle roof framing.

Variations of a hip roof. From simple to very complex computer generated hip roof designs. Pavilion roof a hip roof on a square structure where all sides join to form a single peak also known as a pyramid roof mansard roof a type of hip roof where each side includes two different sloping angles with the lower angle much steeper than the upper angle. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration.

For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. Tented roof a multi sided polygonal hip roof with steeply pitched slopes that rise to a.
