    CAA Level 3 Apprenticeship Diploma in Construction (Roof Slating and Tiling) (QCF) (Pilot)

    Topic Overview

    The CAA Level 3 Apprenticeship Diploma in Construction (Roof Slating and Tiling) (QCF) (Pilot) is a specialised qualification designed for apprentices working towards becoming skilled roof slaters and tilers. This diploma covers advanced techniques in installing natural slate, concrete tiles, clay tiles, and fibre cement slates on both new builds and existing structures. It emphasises safe working practices, accurate measurement, cutting, and fixing methods, as well as understanding weatherproofing and ventilation requirements. This qualification is part of the Construction & Building Services suite under Cskills Awards (NOCN Group) and is a key stepping stone for achieving full competency in the roofing trade.

    Mastering roof slating and tiling is critical for ensuring buildings are protected from the elements, structurally sound, and aesthetically pleasing. This diploma goes beyond basic roofing skills, teaching apprentices how to interpret complex roof designs, work with different materials, and comply with building regulations. It also covers health and safety legislation, risk assessment, and the use of personal protective equipment (PPE). By completing this qualification, apprentices demonstrate they can work independently or as part of a team on residential, commercial, and heritage projects, making them valuable assets to employers.

    This qualification fits into the wider construction industry by addressing the growing demand for skilled roofers who can deliver high-quality, durable roofing solutions. It aligns with the National Occupational Standards (NOS) for roofing and prepares apprentices for further progression, such as the Level 3 NVQ Diploma in Roofing Occupations or supervisory roles. The pilot nature of this diploma means it has been developed with industry input to ensure it meets current best practices and technological advancements in roofing materials and techniques.

    Key Concepts

    Core ideas you must understand for this topic

    • →Understanding different roofing materials: natural slate, concrete tiles, clay tiles, and fibre cement slates, including their properties, grading, and appropriate applications.
    • →Correct fixing methods: nailing, clipping, and hook fixing for slates and tiles, ensuring correct lap, gauge, and headlap to achieve weathertightness.
    • →Roof geometry and setting out: calculating roof pitch, determining batten gauge, and marking out for cut slates/tiles at hips, valleys, and verges.
    • →Weatherproofing details: installing underlay, battens, flashings (lead, aluminium, or GRP), and ventilation systems to prevent condensation and water ingress.
    • →Health and safety compliance: working at height safely, using scaffolding and ladders, handling materials to avoid manual handling injuries, and following COSHH regulations for adhesives and sealants.

    Learning Objectives

    What you need to know and understand

    • Demonstrate the safe and efficient use of specialist hand and power tools for cutting, nibbling, and fixing plain tiles on complex roof features.
    • Interpret and apply technical information such as drawings, specifications, and manufacturer guidance to plan advanced plain tiling work.
    • Evaluate the structural and weathertightness requirements for advanced plain tiling at hips, valleys, abutments, and around roof penetrations.
    • Apply underpinning knowledge of material properties, building physics, and relevant British Standards to select appropriate fixing methods and underlay systems.
    • Assess the condition of tools and equipment before use and carry out routine maintenance to ensure operational effectiveness and safety.
    • Analyse site conditions and roof geometry to determine the most efficient setting out and bond patterns for plain tiles.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly setting out and executing a cut plain tile to fit neatly around a roof window without compromising water-shedding performance.
    • Learner must demonstrate the correct procedure for forming a closed valley with plain tiles, including appropriate underlay and bonding pattern.
    • Evidence of selecting the correct nail type and length for tile fixings based on batten thickness and exposure, as per manufacturer data sheets.
    • Marks should be given for accurate measuring and marking of tiles using a tile gauge and bevel, with cuts made cleanly using appropriate cutting equipment.
    • Assessor to check that the learner has safely isolated and guarded power tools, and is wearing correct PPE throughout the operation.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡In written assignments, always reference current British Standards (e.g., BS 5534) and manufacturer technical bulletins to justify your decisions.
    • 💡When demonstrating practical skills, narrate your actions to explain tool choices and safety checks to the assessor.
    • 💡Prepare a clear photo sequence of your advanced tiling work to provide evidence of setting out, cutting processes, and finished details.
    • 💡For knowledge-based questions, link your answers to real-world scenarios on site to show applied understanding of weathertightness and durability.
    • 💡Always show your working out for calculations of batten gauge and slate/tile quantity. Examiners award marks for method, not just the final answer, so write down each step clearly.
    • 💡When describing fixing methods, use the correct terminology (e.g., 'headlap', 'side lap', 'gauge') and specify the number and type of fixings per slate/tile. This demonstrates technical knowledge and attention to detail.
    • 💡In practical assessments, prioritise safety and neatness. Examiners look for safe working practices (e.g., correct use of PPE, secure scaffolding) and tidy workmanship (e.g., straight courses, consistent gaps). Even if you make a small error, a safe and tidy approach can save marks.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to check the condition of cutting blades or discs before use, leading to chipped or uneven tile edges.
    • Using the wrong nailing pattern or nail size, resulting in insecure fixings that may fail in high winds.
    • Incorrectly lapping underlay at valleys or abutments, causing water ingress and premature roof failure.
    • Misreading technical drawings and miscalculating gauge, leading to uneven courses and excessive cutting waste.
    • Neglecting to account for thermal movement when detailing abutments, causing cracking of mortar or sealant.
    • Misconception: All slates and tiles can be fixed using the same method. Correction: Different materials require specific fixing techniques; for example, natural slates often need two nails, while concrete tiles may use clips or nails depending on the pitch and exposure.
    • Misconception: The underlay is optional if the roof is well-constructed. Correction: Underlay is a critical secondary weatherproof layer; it must be installed correctly with appropriate laps and taped joints to prevent water ingress from wind-driven rain or snow.
    • Misconception: Cutting slates and tiles is straightforward and doesn't affect performance. Correction: Poor cutting can lead to weak points, uneven gaps, and water penetration; cuts must be clean, accurate, and positioned correctly (e.g., not too close to nail holes).
