Level 3 NVQ Diploma in Heritage Skills (Construction)—Roof Slating and Tiling

Level 3 NVQ Diploma in Heritage Skills (Construction)—Roof Slating and Tiling

A work-based NVQ Diploma for heritage roof slaters and tilers conserving, re-laying, replacing and repairing traditional roof coverings.

Overview

The Level 3 NVQ Diploma in Heritage Skills (Construction) – Roof Slating and Tiling Occupations is a competence-based qualification for people carrying out specialist roofing work on traditional, historic and architecturally significant buildings.

It confirms the ability to work as a competent heritage roof slater and tiler, combining established roofing skills with conservation principles. The qualification focuses on retaining significant historic fabric wherever practicable, salvaging reusable roof coverings, matching replacement materials appropriately and carrying out work in a way that respects the character and construction of the existing roof.

Mandatory competence includes conservation and restoration practice, re-laying heritage roof coverings, replacing roof coverings and carrying out heritage roof repairs and maintenance. Learners must also demonstrate the ability to plan their work, establish suitable methods, manage resources, work safely and maintain effective occupational relationships.

Practical work can involve natural and stone slates, clay tiles, peg tiles, flashings, fittings and associated roof components. Depending on the optional units selected, competence may also include plain tiling, regular or random natural slating, curved and swept details, mitred details, vertical slating or weathering leadwork.

The qualification is work-based. Competence is established through evidence produced while carrying out genuine occupational activities rather than through simulated roofing exercises. This makes it particularly relevant to experienced roofers who are already working on traditional or heritage buildings and need formal recognition of their specialist competence.

Current approved versions use closely aligned occupational structures. The verified structures comprise eight mandatory units together with two selected optional technical units. Minor differences in administrative wording or unit presentation can occur between approved versions, but the core occupational purpose and heritage roofing competence remain consistent.

For employers, the qualification provides evidence that a worker has demonstrated specialist heritage roofing competence against nationally recognised occupational requirements, including safe working at height, protection of historic fabric, appropriate material use and the completion of conservation-sensitive roof work.

Who It’s For

This qualification is primarily intended for roof slaters and tilers who already carry out, or have sufficient access to, heritage roofing work and are able to demonstrate their competence on genuine construction and conservation projects.

Suitable learners are normally working with traditional roof coverings and have responsibility for completing work to specifications while making appropriate decisions about existing materials, roof details, conservation requirements and safe methods of work.

Typical occupational settings include historic and traditional buildings, listed buildings, conservation areas, places of worship, public buildings, stately homes, vernacular buildings and other structures where existing roof fabric or traditional roofing techniques need to be preserved.

Learners need realistic opportunities to:

  • inspect and work with existing heritage roof coverings

  • remove coverings without unnecessarily damaging reusable materials

  • identify, clean, sort, stack and store salvageable slates, tiles and associated components

  • re-lay traditional roof coverings

  • replace deteriorated or inappropriate roof coverings

  • repair and maintain existing heritage roofs

  • work to eaves, verges, ridges, hips, valleys, abutments and roof openings where required

  • work safely at height using appropriate access and working platforms

  • interpret drawings, specifications, work instructions and conservation requirements

  • use traditional and modern hand tools, power tools and ancillary roofing equipment

  • work with relevant new or reclaimed materials according to the assessed units

  • communicate with clients, supervisors, conservation professionals and other trades where these form part of the project.

Because workplace skills evidence cannot be simulated for the occupational units, a learner normally needs employment, self-employment or another genuine workplace arrangement that provides sustained access to appropriate heritage roofing projects.

Occupational Endorsements and Optional Specialisms

The qualification is already occupationally specialised towards heritage roof slating and tiling, but individual units contain further endorsements that define the materials, building contexts or technical roofing activities against which competence has been demonstrated.

These endorsements matter because the qualification does not assume that every heritage roofer works on every possible covering, roof detail or type of historic building.

Heritage Roof-Covering Endorsements

The mandatory re-laying unit requires evidence across a specified selection of heritage roof-covering materials or components. The available areas include:

  • single-lap clay tiles

  • clay plain tiles

  • peg tiles

  • stone slates

  • regular-sized natural slates

  • random-length and random-width natural slates

  • flashings

  • associated fittings and components.

Competence must be demonstrated against three of the specified areas rather than every category.

The mandatory replacing and repairing or maintaining units use a different form of endorsement. Evidence is required from two recognised heritage building or location contexts, which can include:

  • vernacular buildings and roofing styles associated with particular geographical areas

  • places of religious worship

  • stately homes

  • public buildings

  • historic buildings

  • castles or fortified buildings

  • conservation areas

  • listed buildings.

This allows the assessment to reflect the heritage environments in which the learner genuinely works.

New and Reclaimed Materials

Several optional roof slating and tiling units are endorsed according to whether competence is demonstrated using new materials or reclaimed materials.

Reclaimed materials require particular consideration because existing or imperial dimensions, variable slate or tile sizes, previous fixing holes, weathering and material condition can affect setting out, gauge, lap and fixing methods.

The endorsement recorded depends on the evidence actually generated. It should not be assumed that achievement with one material category automatically proves competence with the other.

Optional Technical Specialisms

Two optional units are selected in addition to the mandatory heritage roofing units. Current structures provide choices covering:

  • plain tile roof coverings

  • regular-sized natural slate to standard roof details

  • natural slate to mitred and vertical details

  • random natural slate with diminishing margins

  • single-lap roof tiles fixed to a set gauge

  • double-lap tiles on curved and swept roof details

  • weathering leadwork to roofs

  • natural slate on curved and swept roof details.

The learner therefore develops a qualification profile that reflects the type of roofing work genuinely carried out in their occupation. Not every optional specialism has to be completed.

Workplace Requirements

The qualification requires substantial access to genuine heritage roofing work. Evidence must demonstrate competence under normal occupational conditions, including the physical, technical and conservation constraints encountered on real roofs.

Suitable projects must provide access to the materials, details, tools and work situations needed for the mandatory units and the learner's selected optional units. A portfolio based only on classroom exercises or purpose-built training rigs cannot replace the required workplace skills evidence.

The workplace must provide realistic opportunities to use and manage resources such as:

  • traditional roof slates, stone slates and tiles appropriate to the work

  • reclaimed coverings where relevant to the learner's endorsement

  • battens, boards or sarking and associated fixings

  • underlays and roofing components where required

  • ridge, hip, valley, verge and abutment components

  • mortar and associated materials where specified by the work

  • flashings and weathering materials

  • sheet lead and leadworking equipment when the leadwork option is selected

  • hand tools, power tools and ancillary roofing equipment

  • safe access equipment and working platforms

  • suitable collective and personal protective measures.

Learners must also be able to access relevant occupational information. This can include drawings, specifications, method statements, risk assessments, schedules, work instructions, manufacturers' information and conservation requirements.

Heritage projects may expose conditions that are not fully visible before coverings are removed. Learners need opportunities to demonstrate that they can recognise changes, defective substrates, unexpected historic fabric or other findings, report matters outside their authority and avoid making unsupported assumptions about how significant historic work should proceed.

Where salvaged materials are involved, workplace evidence should show appropriate identification, handling, protection and storage so that reusable historic components are not lost through poor site practice.

Learning Outcomes

Successful learners demonstrate the ability to:

  • interpret drawings, specifications, schedules, risk assessments, method statements and other information relevant to heritage roof work

  • confirm the scope, sequence, resources and occupational method required for roofing activities

  • identify missing or conflicting information and obtain clarification before proceeding

  • assess materials and roof components for suitability, condition and intended use

  • work safely at height and apply appropriate health, safety and welfare controls

  • protect existing buildings, historic fabric, completed work and surrounding areas from avoidable damage

  • recognise the significance of traditional construction and work in accordance with conservation and restoration principles

  • apply minimum-intervention and reversible-alteration principles where required by the heritage work

  • remove existing roof coverings while salvaging suitable reusable materials

  • clean, sort, stack, store and protect retained slates, tiles and associated components

  • re-lay heritage roof coverings while maintaining the character and technical performance of the existing roof

  • replace deteriorated or inappropriate roof coverings using suitable materials and traditional details

  • repair and maintain existing slate and tiled heritage roofs

  • determine appropriate lap, gauge, setting-out and fixing requirements for the materials and details being installed

  • integrate retained and replacement materials without unnecessarily disturbing significant existing fabric

  • use hand tools, power tools and specialist roofing equipment correctly

  • complete selected specialist roof slating, tiling or leadwork activities according to the optional units achieved

  • identify defects, unexpected conditions and work requiring additional specialist knowledge

  • stop and report where work reaches a point at which proceeding would depend on conjecture

  • recognise and report protected or endangered flora and fauna encountered during heritage work

  • record conservation and restoration work using appropriate written, photographic or digital information

  • communicate effectively with supervisors, clients, other trades and relevant project personnel

  • complete work to the required specification and programme while reporting circumstances that affect progress.

Units

Current approved versions use a structure of eight mandatory units and eight available optional units. All eight mandatory units must be achieved, together with two units selected from the optional group.

The mandatory group combines general occupational competence with specialist heritage roofing skills. The optional group allows the qualification to reflect the learner's actual slating, tiling or roof leadwork responsibilities. Optional availability and administrative wording should always be confirmed against the approved version being undertaken.

Assessment

Assessment is designed to establish whether the learner can perform heritage roof slating and tiling competently under genuine workplace conditions. The qualification is assessed against occupational performance and knowledge requirements rather than through a single final practical examination.

Evidence is assembled across the mandatory units and the two optional units selected for the learner's occupational role. The assessor must be satisfied that evidence is authentic, current, sufficient and relevant to the required endorsements.

Workplace Observation

Direct observation is a central source of evidence for practical competence. An occupationally competent assessor can observe the learner carrying out activities such as:

  • carefully stripping existing heritage roof coverings

  • salvaging and protecting reusable slate or tile

  • setting out battens, lap and gauge

  • re-laying historic roof materials

  • replacing defective coverings

  • repairing existing roofs

  • completing eaves, verges, ridges, hips, valleys and abutments

  • integrating retained and replacement materials

  • working at height using appropriate controls

  • completing advanced slate, tile or leadwork details included in the optional units.

Observation allows the assessor to judge not only the finished roof but also the decisions, preparation, sequencing, material handling, safety controls and conservation practices used to achieve it.

Portfolio and Work Products

A portfolio is used to bring together evidence showing how the learner has met the required occupational criteria.

Relevant evidence can include:

  • assessor observation records

  • photographs showing roof condition and work at appropriate stages

  • completed roof areas and details

  • drawings, specifications and work instructions used by the learner

  • risk assessments and method information relevant to the work

  • records of conservation findings or changes to the planned work

  • written, photographic or digital records of restoration activity

  • evidence of salvaged and stored heritage materials

  • job documentation demonstrating the learner's involvement

  • completed lead weatherings where the leadwork option is being assessed

  • records relating to defects, reporting and remedial action.

Photographs and documents support assessment but do not replace direct evidence that the learner personally performed the required occupational skills.

Professional Discussion and Questioning

Practical observation cannot always reveal the full technical reasoning behind an action. Professional discussion, oral questioning or written questioning can therefore be used to confirm underpinning knowledge.

Questions can address matters such as:

  • why a particular traditional material or fixing method was selected

  • how lap and gauge were determined

  • the effect of reclaimed imperial materials on setting out

  • reasons for retaining rather than replacing historic fabric

  • minimum-intervention and reversibility principles

  • responses to unexpected historic construction

  • correct procedures when conjecture would otherwise be necessary

  • roof defects and their likely causes

  • working-at-height controls

  • material characteristics and limitations

  • environmental and waste responsibilities

  • protection of sensitive historic fabric

  • communication and reporting responsibilities.

Witness Testimony and Supporting Records

Statements from suitably knowledgeable people can support evidence where they have directly witnessed the learner carrying out relevant work.

Witness evidence may be particularly useful for activities occurring between assessor visits, but it must relate clearly to the learner, the project, the work undertaken and the standard of performance demonstrated.

Employer and site records can also corroborate the learner's responsibility for particular heritage roofing activities.

Recognition of Prior Learning

Relevant previous experience and existing evidence can be considered where it demonstrates the same current occupational requirements.

Recognition of prior learning does not remove the need to prove competence. Historic photographs, employment experience or previous training are only useful where sufficient evidence can establish that the learner has actually met the required performance and knowledge criteria.

Simulation and Sufficiency of Evidence

Workplace evidence of the practical skills in these occupational units cannot be simulated. The learner must therefore demonstrate the required heritage roofing activities on real work rather than relying on training-centre exercises designed to imitate workplace conditions.

Evidence must also cover the endorsements attached to relevant units. This means, for example, that a learner cannot complete the re-laying unit by demonstrating only one roof-covering type when the unit requires a broader endorsed selection.

Similarly, replacing and repairing or maintaining heritage roof coverings require evidence from the specified number of heritage building or location contexts.

Completion is achieved when all mandatory units, the required optional units and their applicable endorsements have been assessed as competent, with sufficient evidence of both practical performance and underpinning knowledge.

Career Progression

The qualification recognises advanced occupational competence in heritage roof slating and tiling. It is therefore most directly relevant to skilled roofers who want to continue developing within traditional and conservation roofing rather than workers seeking only an introduction to roofing.

Progression depends on experience, the types of projects undertaken and any additional specialist or supervisory competence required for a future role.

Skilled Heritage Roofing Roles

The qualification is directly relevant to work as a:

  • heritage roof slater and tiler

  • traditional roofing craftsperson

  • conservation roofing operative

  • specialist natural slate roofer working on heritage projects

  • traditional tile roofer working on historic buildings.

The exact responsibilities depend on the learner's experience and the optional units and endorsements demonstrated.

Specialist Craft Development

Experienced heritage roofers can broaden their technical range by developing further competence in areas such as:

  • advanced natural slate detailing

  • random and diminishing-course slating

  • curved and swept slate or tile work

  • traditional peg and plain tile roofing

  • roof weathering leadwork

  • other specialist heritage roofing techniques relevant to the buildings on which they work.

Specialist activities should only be undertaken where the individual has the necessary competence and where any additional technical, safety or project requirements have been met.

Supervision and Management

With suitable occupational experience, a heritage roofer may progress towards responsibility for coordinating teams, planning specialist work, controlling resources or supervising conservation projects.

A relevant progression route can include a Level 4 NVQ Diploma in Construction Site Supervision (Construction) – Traditional and Heritage Building where the person's role develops into site supervision.

Those who later take substantial management responsibility for traditional and heritage construction projects may progress towards a Level 6 NVQ Diploma in Construction Site Management (Construction) – Traditional and Heritage Building, subject to having access to the management responsibilities needed for assessment.

CSCS Card

The exact qualification is currently mapped to the Heritage Roof Slating & Tiling occupation for a gold advanced-craft CSCS route. The relevant card is the Gold Skilled Worker card at advanced-craft level.

Holding the qualification supports the qualification requirement for this mapped occupation, but completing the NVQ does not automatically issue a CSCS card. The worker must make a separate card application and meet the other current scheme requirements.

Heritage Roof Slating & Tiling Card Mapping

The occupational mapping specifically identifies:

  • the Level 3 NVQ Diploma in Heritage Skills (Construction) – Roof Slating and Tiling Occupations

  • the occupation of Heritage Roof Slating & Tiling

  • the gold advanced-craft route.

This is an exact occupational mapping rather than an assumption based simply on the qualification being a Level 3 construction NVQ.

Applicants should provide the required qualification evidence when making the card application and confirm that the occupational description matches the work for which the card is required.

Health, Safety and Environment Test

The mapped test for Heritage Roof Slating & Tiling is the CITB Health, Safety and Environment Specialist Work at Height test.

For a normal CSCS application, the appropriate Health, Safety and Environment test must have been passed within the required current validity period, unless an approved alternative applies.

Applicants should check the current Card Finder immediately before applying because card names, evidence arrangements, test requirements and application rules can change.

FAQs

The following questions address practical issues that are particularly important for learners considering this heritage roof slating and tiling qualification, including workplace access, materials, endorsements, assessment and card requirements.

No. This qualification specifically assesses heritage roof slating and tiling and includes mandatory competence in conservation and restoration, re-laying heritage roof coverings, replacing them and carrying out heritage repairs and maintenance.

A general roofing qualification may assess competent installation of roofing systems without requiring the same breadth of conservation principles, salvage practices, historic-fabric protection and heritage project evidence.

Yes, genuine workplace access is essential. The practical skills evidence required by the occupational units cannot be simulated.

The learner therefore needs access to real projects that provide sufficient opportunities to demonstrate the mandatory heritage roofing activities, selected optional units and relevant endorsements.

No. Current approved structures require all eight mandatory units and two selected optional units.

The optional units should normally reflect the learner's genuine work, such as natural slate, plain tile, advanced curved or swept details, or weathering leadwork. Completing one optional specialism does not imply competence in the others.

Not necessarily for every optional unit. Several optional slating and tiling units use an endorsement for either new materials or reclaimed materials.

The endorsement should reflect the material used in the workplace evidence. Working successfully with reclaimed coverings can require additional attention to condition, sizing, existing holes, dimensional variation, lap, gauge and visual integration.

The qualification assesses more than the age of the property. Heritage competence includes recognising significant existing fabric, retaining materials where appropriate, salvaging reusable coverings, integrating new and existing work sensitively and applying conservation principles such as minimum intervention.

Learners must also know when to stop and report rather than continue on the basis of conjecture, and they may need to record conservation work and unexpected findings.

Not for the required workplace skills evidence. The occupational units specify assessment in a work environment and do not permit simulation of the practical workplace competence.

Training activities can support skills development, but final competence evidence must come from genuine occupational work that provides the required tasks and endorsements.

Strong evidence commonly combines assessor observation with work products and supporting records. This can include evidence of stripping and salvaging coverings, setting out, re-laying, replacement and repairs, together with photographs, specifications, drawings, conservation records and relevant job documentation.

Questioning or professional discussion is used where the assessor needs to confirm technical knowledge, conservation reasoning, safety responsibilities or decisions that cannot be established from the finished roof alone.

Yes. The qualification is specifically mapped to the Heritage Roof Slating & Tiling occupation for the gold advanced-craft route.

The qualification does not issue the card automatically. A separate application is required, and the mapped Health, Safety and Environment test is the Specialist Work at Height test. Applicants should confirm the current Card Finder requirements before applying.
