A ridge board is a horizontal member that supports the upper ends of the rafters in a sloped roof system. It helps to connect and stabilize the rafters at the peak of the roof, providing structural integrity to the roof framing system.
A mountain ridge.
Another ridge similar to the Mid-Atlantic Ridge can be found in the Indian Ocean, known as the Southwest Indian Ridge. It is a divergent boundary where the African Plate and the Antarctic Plate are moving apart. This ridge, like the Mid-Atlantic Ridge, is associated with volcanic activity and the creation of new oceanic crust.
Knowledge of undersea features such as the Midatlantic Ridge gradually grew during the 19th century as accurate hydrographic surveys were made across the world. The ridge is many thousands of miles long, so parts of it would have been discovered at different dates years apart.

The Shadow of Lightning Ridge was created on 1920-04-03.
The purpose of a ridge board in a roof structure is to provide support and stability to the rafters at the peak of the roof. It helps to distribute the weight of the roof evenly and prevent sagging or shifting of the roof structure.
A ridge board doesn't support rafters of the bridge whereas a ridge beam does.
In roof construction, a ridge board is a horizontal piece that connects the upper ends of the rafters, while a ridge beam is a larger, structural beam that supports the weight of the roof. The ridge board is mainly for alignment and connection, while the ridge beam provides structural support.
It is true that no ridge board is needed if the pitch is steep and rafters are directly opposed. This is the only time a ridge board is not needed.
One alternative method for roof construction that eliminates the need for a ridge board is using a ridge beam instead.
You will need something that will substitute for the same role as a ridge board. If you are building a structure, you must be able to understand the physics of the structural loads. Think about what role the ridge board plays in the structure of the roof. What would happen if it was gone? The ridge board prevents side to side motion. without a similar structure your roof would collapse sideways.
You would not have to add a ridge board, particularly if you are planning to build the addition roof directly over the existing roof.
We just got a home inspection today with this problem. There is a possibility for the rafters to separate from the ridge board from hinge action.
To dig dirt of in the wild
The horizontal board that connects two rafters on opposite sides of a ridge board is called a collar tie. It helps to stabilize the rafters and prevent them from spreading apart, ensuring the structural integrity of the roof.
For a typical gable roof you have a ridge board at the top with rafters running from the ridge to the top plates of the walls
You need it when using engineered trusses.
