The constituents of a hip roof happen to be the common rafters ridge board jack rafters and hip rafters. 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. Determining the ridge beam height. Importantly though you must add the thickness of the ridge back on to that measurement so we can use the same common rafters already measured we ve removed the 50mm purple ridge from above so need to now add 50mm on to the new longer ridge.

Attach 4 6 centering rafters and lift the ridge beam into place. Hip roofs are constructed with four rafters that usually meet on a ridge board that is situated at the middle portion of the roof.

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. To calculate the length of a ridge in a hipped roof you simply subtract the width away from the length. Whereas in the case of square buildings hip roofs are more commonly pointed toward the top portion while forming a pyramid like structure.
