Framing Hip Roof With Different Pitches

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.

Framing hip roof with different pitches.

Explore framing complexities that result when roofs of two different pitches intersect. 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. For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. A hip roof or a hipped roof is a style of roofing that slopes downwards from all sides to the walls and hence has no vertical sides.

Now outline the biggest rectangle inside the building layout. But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons. Now draw the centerlines for all rectangles that are formed inside. Discover 5 types of hip roofs plus 22 examples of many houses that incorporate all the different hipped roof styles.

From simple to very complex computer generated hip roof designs. Learn more about off angle roof framing. Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results. Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries.

The pitch of the unequal hip rafter can be expressed in relation to either the main roof or the secondary roof. Here roofs are constructed with an angle of 90 degrees. Modern residential hip roof construction uses common pitch ratios in general. Blind valleys simplify framing 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.

Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same. Select the following information by using the drop downs to enter values in feet and inches. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration.
