Ventilating pitched roofing


The purpose of this standard is to provide the candidate with the knowledge and skills to install a ventilating pitched roof, including the: tiles, battens, membrane (high resistance (sarking), insulation, ridge tiles, and verge tiles.

CITB has developed this standard in discussion with industry


Minimum 1 day of 6 learning hours

Purpose / scope

The purpose of this standard is to provide the candidate with the knowledge and skills to install a ventilating pitched roof, including the: tiles, battens, membrane (high resistance (sarking), insulation, ridge tiles, and verge tiles.

The scope of this standard excludes slates and excludes installing the:

  • flashings, ornamental ridge tiles, hip tiles, vented tiles, inclined valleys, junctions, fittings, accessories, insulation, protrusions, and abutments

The scope of this standard covers:

  • new installs and roof conversions.
  • practical training using one type of ventilated roof system for the time available
  • types, purpose, and features of ventilated roofing systems
  • differences between ventilated and non-ventilated roof systems
  • interpret simple instructions and drawings
  • tools and equipment (hand & power)
  • calculate batten spacing and make a gauging stick
  • calculate side lap and make a marking stick
  • work safely
  • install: tiles, battens, membrane (high resistance (sarking), insulation, ridge tiles, and verge tiles.
  • mark and cut tiles
  • maintain a clean and tidy workplace
  • if the weather deteriorates
  • clean up and dispose 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 a slating or tiling introduction training course.

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 training to this standard 
  • At least 2 years relevant industrial experience
  • A verifiable CV.


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.


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.


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

Approval date

November 2018

Review cycle

Either on request or in 3 years from approval date.
