Hip Rafter Offset/Shift Examples

Hip Rafter Offset/Shift
The Hip Rafter Offset/Shift aligns the edges of the hip rafter material with the roof planes which are determined by the given Roof Slope Angles. This dimension is perpendicular to the hip rafter run line. You will layout the top of the unbacked hip rafter with these dimensions. 



In these example drawings the Eave angle is 90° and the two roof pitches are 8:12 & 10:12. The width of the hip rafter 3.5".






Hip Shift = Gratgrundverschiebung in German.

In these example drawings the Eave angle is 120° and the two roof pitches are 8:12 & 10:12. The width of the hip rafter 5.5".





In these example drawings the Eave angle is 135° and the roof pitches are equal @ 10:12. The width of the hip rafter 3.5".










In these example drawings the Eave angle is 90° and the roof pitches are equal @ 10:12. The width of the hip rafter 1.5".
