This unit specifies the skills and knowledge required to set out and install a curved roof on a roof structure. It includes drawing fabrication patterns based on sketches of roof coverings, calculating curve dimensions and sheet lengths, and selecting required roofing materials.
Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, incl the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
* determining sheet length and developing a pattern or drawing for the manufacture of the curved roof components
* installing pre-curved roof covering to a bullnose or curved roof structure of a minimum eave width of three metres, incorporating:
* one internal or one external corner
* curved flashing or valley
* determining sheet length for a sprung-curved roof
* installing pierced-fixed convex sprung-curved roof covering to a curved roof structure, incorporating a minimum width of two sheets.
The qualified trainer and assessor will advise students of class notes, reading materials produced by VU Polytechnic and further support via VU Polytechnic e-learning system and/or in person.
