Calculating the length of a ridge board is a crucial step in the roofing process. The ridge board is the horizontal board that sits at the peak of the roof and connects the two roof planes. It provides structural support to the roof and helps to shed water.
The length of the ridge board is determined by the pitch of the roof and the width of the house. The pitch of the roof is the angle of the roof planes, and it is typically expressed in degrees. The width of the house is the distance between the outside walls of the house.
