In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
A key output of roof estimators is recommending to customers, roof designers and manufacturers a bill of estimates of roof material. This requires knowledge of the material to be used, the manufacturing and quality process.

Learners credited with this Unit Standard are able to demonstrate an understanding of the manufacturer's responsibility for translating a roof and truss design into an actual roofing solution that is safe for the client, and manufactured in a cost effective manner for the fabricator.

To achieve this, they are able to apply an understanding of:
  • Recommend material options for roof design.
  • Prepare material by demonstrating an understanding of organisational and sector requirements.
  • Demonstrate understanding of manufacturing tolerances.
  • Describe manufacturing limitations.
  • Conduct quality control as demanded by context.

    This Unit Standard is intended to promote skills in the wood processing and construction fields in order to raise competence levels in the various industries served by informed and competent workers. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are competent in:
  • Communication and mathematical literacy at NQF Level 3 or an equivalent.

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner or moderating the assessment of a learner against the unit standard must be registered as an assessor with the relevant Education, Training, Quality, Assurance (ETQA) Body, or with an ETQA that has a Memorandum of Understanding with the relevant ETQA.
  • Any institution offering learning that will enable the achievement of this unit standard must be accredited as a provider with the relevant Education, Training, Quality, Assurance (ETQA) Body, or with an ETQA that has a Memorandum of Understanding with the relevant ETQA.
  • Assessment and moderation of assessment will be overseen by the relevant Education, Training, Quality, Assurance (ETQA) Body, or by an ETQA that has a Memorandum of Understanding with the relevant ETQA, according to the ETQA`s policies and guidelines for assessment and moderation.
  • Moderation must include both internal and external moderation of assessments, unless ETQA policies specify otherwise. Moderation should also encompass achievement of the competence described in the associated unit standards.
  • Anyone wishing to be assessed against this qualification may apply to be assessed by any assessment agency, assessor or provider institution that is accredited by the relevant ETQA.

    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    This will be achieved when the qualifying learner identifies site documents and their use. 

    UNIT STANDARD CCFO WORKING

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
