Using DEWALT RAFTER SQUARE (continued)
17) When building a hip roof the ridge board should be left about
a foot longer than necessary at the ends. Then a common rafter, which
has been cut to size, is placed an the center of the end plate, and the
upper end positioned alongside the ridge board, aligning the top end of
the common rafter with the top of the ridge board.
The ridge board is then marked at the end of the common rafter.
If a center common ridge rafter is used, the ridge board is cut to
length at this mark, and the hip rafters are fastened at the tap end of
the common ridge rafter.
If no center common ridge rafter is used, add 2 inches to the
length al the ridge board from the mark just made, to provide a surface
to fasten the upper end of the hip rafter, and cut off the ridge board at
this point.
