Overview

The purpose of this standard is to provide the candidate with the knowledge and skills to install interlocking tiles for a new roof, including the: membrane, battens, main tiles, ridge tiles, hip tiles, verge tiles, valley tiles, fittings, and flashings.

Duration

Minimum 3 days of 6 learning hours

Purpose / scope

The purpose of this standard is to provide the candidate with the knowledge and skills to install interlocking tiles for a new roof, including the: membrane, battens, main tiles, ridge tiles, hip tiles, verge tiles, valley tiles, fittings, and flashings.

The scope of this advanced standard covers:

  • use of a roofing rig with a valley and a hip
  • install profiled and flat interlocking tile types
  • interlocking tiling systems to include dry fix
  • interpret instructions and drawings
  • tools and equipment (hand & power)
  • estimates for materials
  • batten spacing
  • gauging and marking sticks
  • side lap
  • storage, handling, and lifting
  • plan the work
  • work safely
  • roof check
  • install: membrane, battens, main tiles, ridge tiles, hip tiles, verge tiles, valley tiles, fittings, and flashings
  • mark and cut tiles
  • soil pipe penetration
  • maintain a clean and tidy workplace
  • weather deterioration
  • disposal of waste materials.

Occupational relevance

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

  • operative and craft.

Candidate prerequisites

The candidate must have completed the interlocking tiles introduction training course.

A basic knowledge of slate and/or tiling roofing terminology and techniques would be beneficial and that the candidate is employed within the roofing industry.

Before candidates perform the work on a construction site, candidates must have successfully completed roofing-specific training for working safely at height.

Instruction / supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

  • a train the trainer or instructional techniques course certificate
  • successfully completed a NVQ level 2 in a roofing associated qualification.
  • at least 10 years relevant industrial experience
  • a verifiable CV.

Delivery

The following method(s) may be used in the delivery of this standard:

  • classroom and workshop

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes, and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

This standard is considered to contain 51 per cent or more practical learning.

This standard is considered to be set at an intermediate level.

Assessment

For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard. 

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the Training Standard. 

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team.

Renewal/refresher

There are no mandatory renewal or recommended refreshment requirements for this standard.

Approval date

November 2018

Review cycle
