The Gable Roof

Cutting of RaftersSetting the Ridgeboard

Gable End Studs

All of the rafter length calculations are line lengths since the thickness of the material is not taken into account. After the line length of the common rafter is determined and marked on the rafter stock, then a 2nd ridge plumb cut line is drawn at exactly ½ the thickness away from the 1st line, measured perpendicularly.

The Framing Square, with the stair gauges set at 6” & 12”, is used to mark the ridge plumb cut line at the top end of the rafter. The distance between the gauges is exactly 13.42”. [6:12 slope].The Speed Square pivots at the top to make the cut lines. Here it is set so that the number ‘8’ below the slot is on the top edge and the angle of cut is 34. [8:12 slope].
