What is rafters definition?

Rafters are structural elements that run from the roof ridge to the eaves and are designed to support the roof decking and provide a slope for proper water drainage. They are typically made of wood and are spaced apart according to the design of the roof and the weight that they need to support. Rafters are an important component of a roof system as they provide structural support for the overall structure. Rafters can be exposed (visible) or hidden within the roof assembly.
