Roof Celine Joists

In this design the tops of the rafters attach to a load bearing ridge beam that runs along the length of the roof.

Roof celine joists.

They are used to support a ceiling above or the floor below. We were told that the joists are not providing structural support and were merely for affixing the flat ceiling. The ceiling joist 2x4s are running at right angles to the beam and rafters across the 12ft span of the room. They are nominally 2 inches thick actual width usually 1 1 2 inches and come in a variety of widths from 8 to 12 inches.

Joists are the parallel horizontal beams that run across an open space joining opposite walls in a building to support both the ceiling below and the floor above. The roof joist is what makes up the ceiling of a home. Joists are traditionally made from timber. Ceiling joist loads ceiling joists are sized based on one of two tables found in the code.

These joists are below the beam and are tied to it by 2x4. These span tables list allowable ceiling joist spans for common lumber sizes based on what design load scenario is applied. Ceiling joists of the first floor of a two story structure often serve as floor joists for the second floor. The joists are horizontal pieces of lumber that span the distance from one side of the home to the other.

A broken roof joist is a serious problem that must be taken care of immediately.
