Roof joist construction.

Joist is a term used in construction for load bearing planks that run horizontally or nearly to horizontally to ground. Joists fit into gaps in the uppermost top plates of the two sides. Notched roof joists connect and hold the longest 2 sides in place. Roof supports which are angled are known as rafters.

For example the i joist is normally most common for floor construction where the joist needs to span great distances over basements or enclosed crawl spaces without using a post and the truss joist typically works best for roof construction where framing members need to span large rooms without placing a wall underneath for support.
