Step Down Hip Roof Truss

There will be step down trusses from the girder truss to the peak.

Step down hip roof truss.

This 26 span truss with a 4 12 roof pitch is the most economical truss we can build. If we go any larger it will require more webbing inside the truss which will directly affect the cost of the truss. Place the 4 6 common rafters in their designated positions along the 2 longest walls and nail them firmly to the wall with a nail gun. Attach 4 6 centering rafters and lift the ridge beam into place.

Hip roof truss layout the initial step in framing this roof is not much different from that of the gabled roof. Differing from the california hip a step down hip system is one where every truss under the hip end plane decreases in height or steps down from the apex until it reaches the hip girder which is placed at a pre determined setback. At the peak common trusses are used to complete the run. This system consists of a girder truss corner girder corner jacks and end jacks.

The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases. The standard roof truss spacing is 2. The same is true if we make it steeper. This step involves finding the run of a common rafter.

You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof. Steeper roof pitches require longer webs which add to the cost. Hip sets are used to construct hip roofs which are roofs that slope from all sides. This is the distance between trusses.

Step down hip roofs are the quickest style of hip truss framing to produce. I agree the step system with a lay over filler i always attatch my short jacks to the girder on ground swing whole thing in place then set next step down trusses all the way to peak with minimal but still safe bracing place the filler truss on top nail it off and you then have a very stout hip system well braced and ready to sheath.
