Roof joist vs rafter.

Rafters are the building components that run diagonally from the wall plate to the apex of a roof structure. Rafters form the foundation for attachment of the roof boards onto which the final roof covering is fixed. Without the tie at the bottom the rafters must be supported at their upper end to prevent the rafter thrust at the lower end. The first case is when the ceiling joists are oriented perpendicular to the rafters.

The major functional difference between the two is that trusses are built mostly with 2x4s in place of the wider dimensional boards. In a typical roof framed with dimension lumber the rafters rest on the exterior wall top plate at the lower end and bear against a ridge board at the top. However in canada the most common material used in residential framing is wood so that is the material we will discuss here. If you live in an area that requires a shed roof rafter to support a heavy load then an spf rafter can only span 7.

Visit the roof framing page for more information on cutting roof rafters and visit the roof pitch calculator for determining rafter lengths based on rise and run. In traditional timber they are nominally 2 inches thick and typically 8 to 10 inches wide. A joist is a horizontal structural member used in framing to span an open space often between beams that subsequently transfer loads to vertical members. Trusses and rafters have many common parts including the sloping rafter boards and a bottom joists that form the ceiling of the space below.

This structural support comes in the form of roofing joists ceiling joists rafters or trusses and can be made from a variety of materials including wood metal reinforced concrete etc. The main difference between joist and rafter is that the joist is a horizontal structural element transferring load from flooring to beams typically running perpendicular to beams and rafter is a structural members in architecture. Rafter span tables use these tables to determine lengths sizes and spacing of rafters based on a variety of factors such as species load grade spacing and pitch. The load resisting concepts of the vaulted ceiling are completely different.

Roof rafter span use this table to determine the maximum lengths of roof rafters based on species and grade of lumber spacing dimensions load and slope. Both of these are for light roof loads. As mentioned above a 2 4 spf shed roof rafter can span 11.
