The engineering principles of the ridge board are a bit more complicated.
Ridge board roof.
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.
This type of framing is a specially designed rafter layout and requires precise and experienced erection.
Definition of ridge board in construction the top board at the peak of a roof.
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.
Remove the spacers in both end wall trusses and put the ridge board in between the 2 gable ends.
Its only job is to provide a connection point for the roof joists on each side of the roof.
Line it up with the top of the truss and nail in place.
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.
Install the ridge board cut to the ridge board to the length of the shed dimension b and mark it 24 inch on center.
The rafters terminate against the ridge board unless the framing is designed to bear rafter against rafter with no ridge board.
The ridge board must be set as perfectly as possible so take your time and use careful measurements.
