In order to obtain the correct length for a common rafter, it is necessary

to:

• subtract the width of the bird’s mouth.

• subtract half the thickness of the ridgeboard.

• subtract half the thickness of the raft.

• add half the thickness of the ridgeboard.

The length of a common rafter for a roof with a span of 30 feet and a rise

of 10 feet is:

The pitch of a roof that has a rise of 8 feet and a run of 12 feet is:

• 1/3

• 2/3

• 8 in 12

• one dimension thicker than a common rafter.

• one dimension less than a common rafter.

• the same thickness as a common rafter.

The roof frame member that is connected between the barge rafter and the gable end is called a:
