Under the planes of a hip set roof, there are many different methods used to frame the trusses. Preferences for any given system hinges upon builder preferences, manufacturing efficiencies, cost, and ceiling requirements. Some of the most common hip systems are outlined below.

All the bottom chords of the end jacks run to the hip girder, allowing for better attachment of the drywall on the ceiling, and the top chords of the end jacks run all the way up to the hip ridge. Proper support of extended top chords is critical. ________________ ________________ _ _ ______________________________ ______________________________ Califor Califor nia nia __________________ __________________ _ _ _____________________ _____________________ _ _ ______ ______ A stepdown hip set provides a girder truss, with a hip jack running from the corners up the ridge until they meet the hip girder. The builder must provide support for the hip ridge, usually in the form of blocking, or hip cats, in between each hip truss up to the peak. The Midwest hip set also provides a girder truss, with hip trusses that step up to the peak. However in a Midwest hip set, you run a rafter up from the corner of the front wall to the hip girder. All the bottom chords of the end jacks run to the hip girder, allowing for better attachment of the drywall on the ceiling. Hip cats must be field cut and installed between the hip trusses if a dropped-in gable is not provided (for more info see Dropped-In Gable)
