Ridge Board Of A Roof

The ridge board and rafters are the strength of the roof.

Ridge board of a roof. Ridge boards can only be used in roofs with slopes from 3 in 12 up to 12 in 12. 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. A 1 in 12 roof pitch roof rises 1 inch for every 12 inches of run. Rafters and a ridge board are the key components of a roof framing system.

If you re using a roofing calculator press the pitch button to input the pitch ratio in the calculator s memory. A ridge board is a non structural member that serves as a prop for opposing rafters to rest against and connect to.

Rafters are nailed to the ridge board and run down to overhang the exterior wall. 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 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. Also measure the length of half of the roof from one side of the ridge beam to the edge of the building.

The ridge board forms the peak and ties the rafters together side to side and end to end. The rafters support the sides or slope of the roof. The ridge board must be set as perfectly as possible so take your time and use careful measurements. The pitch of a roof determines the height of the ridge board that runs the length of the house.

Its only job is to provide a connection point for the roof joists on each side of the roof. Carpenters measure roof pitch as inches of rise per 12 inches of run. If the roof rises 7 inches 18 cm for every 1 foot 0 30 m its pitch would be written as 7 12. Other elements like gable studs and cross ties supply additional bracing.

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. 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.
