Application

This unit of competency specifies the skills and knowledge required to set out, construct and erect pitched roofs to accommodate roof coverings for weatherproofing purposes, 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 determining the required materials and process, and constructing scotch valley gable, broken hip and valley roof structures.
Completion of the general construction induction training program specified by the model Code of Practice for Construction Work is required for any person who is to carry out construction work. Achievement ofCPCWHS1001Prepare towork safely in the construction industrymeets this requirement.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
