Framing Hip Roof With Different Pitches

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.

Framing hip roof with different pitches.

Modern residential hip roof construction uses common pitch ratios in general. 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. The pitch of the unequal hip rafter can be expressed in relation to either the main roof or the secondary roof. Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results.

A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. Select the following information by using the drop downs to enter values in feet and inches. Now draw the centerlines for all rectangles that are formed inside. Hip and valley roof framing is no so complex as compared to hip roof framing procedures.

Here roofs are constructed with an angle of 90 degrees. Discover 5 types of hip roofs plus 22 examples of many houses that incorporate all the different hipped roof styles. 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.

Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries. Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same. First of all you need to design the layout of building. 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.

For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. Now outline the biggest rectangle inside the building layout. From simple to very complex computer generated hip roof designs.
