This unit of competency specifies the skills and knowledge required to plan, prepare, set out and construct pitched roofs on irregular plan building shapes, meeting all relevant requirements of the National Construction Code (NCC), Australian Standards, work health and safety (WHS), and Commonwealth and state or territory legislation.

The unit includes gable, hip, hip and valley, or combinations of these in roofs that are applied to different types and styles of buildings. The roofs may have skewed, splayed or octagonal ends, may contain two separate roof pitches in the one structure, and have varying eave widths.
