Ridge board roof.

Definition of ridge board in construction the top board at the peak of a roof. The engineering principles of the ridge board are a bit more complicated. Line it up with the top of the truss and nail in place. Ridge boards and beams in traditional house framing also called stick framing a basic roof frame consists of opposing pairs of sloping rafters that meet at their top ends at a ridge board or ridge beam.

The rafters and trusses that are part of the overall roof structure are connected along the body of the ridge board helping to create a durable framework that protects the rooms of the structure underneath. Specifically the ridge board is a section of solid timber or metal that is positioned horizontally along the line of the ridge of the roof. The rafters terminate against the ridge board unless the framing is designed to bear rafter against rafter with no ridge board. So the ridge is basically the peak of a roof but ridge also refers to the board or beam that is used in building the ridge.

Because the ridge board is a smaller member typically only an inch thick sometimes even less it is not a structural member and doesn t carry the gravity load. The ridge board must be set as perfectly as possible so take your time and use careful measurements. The ridge board runs the length of the building and provides support for the tops of the rafters helping the whole roof structure work together as a system. Install the ridge board cut to the ridge board to the length of the shed dimension b and mark it 24 inch on center.
