  • assumptions for tasks
  • speed versus quality
  • causes of high and low quality
  • impacts of high and low quality
  • solutions to address low quality
  • best-practice roofing techniques.

Occupational relevance

Training delivered against this standard is relevant to the following occupational group(s):

  • operative and craft
  • supervision
  • management and leadership.

Candidate prerequisites

There are no candidate pre-requisites as part of this standard. However, a basic knowledge of slate and/or tiling roofing terminology and techniques would be beneficial.

Instruction / supervision
