Pitch is the amount of angle or slope the roof has. Use a pencil to jot the width down somewhere. Roof trusses arrive at the jobsite on the bed of a large truck. Every step of the truss installation follows explicit instructions from the manufacturer.

The first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof. Attach 4 6 centering rafters and lift the ridge beam into place. Write on a spare sheet of paper or a section of exposed wood. This is denoted two ways a 1 3 or 1 4 pitch in fractions and a 6 12 pitch in inches which means the roof rises 6 inches for each 12 inches of run.

A framing square is traditionally used for laying out the roof and determining pitch. Setting the first trusses. 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.
