    CAA Level 2 Apprenticeship Diploma in Construction (Roof Slating and Tiling) (QCF) (Pilot)

    Topic Overview

    The CAA Level 2 Apprenticeship Diploma in Construction (Roof Slating and Tiling) (QCF) (Pilot) is a vocational qualification designed for apprentices working towards becoming skilled roof slaters and tilers. This diploma covers the essential knowledge, skills, and behaviours required to install, repair, and maintain roofs using natural slate, concrete tiles, and clay tiles. It is part of the Construction & Building Services framework under Cskills Awards (NOCN Group) and is delivered through a combination of on-the-job training and college-based learning.

    This qualification is critical for ensuring that roofing work meets UK building regulations, safety standards, and industry best practices. Apprentices learn to interpret technical drawings, select appropriate materials, and apply correct fixing methods for different roof types, including pitched roofs, valleys, hips, and ridges. The diploma also emphasises health and safety, particularly working at height, manual handling, and the use of personal protective equipment (PPE).

    As a pilot qualification, it reflects the latest industry requirements and prepares apprentices for progression to Level 3 or specialist roles in heritage roofing, green roofing, or site supervision. Mastery of slating and tiling is fundamental to the construction industry, as roofs protect buildings from weather and contribute to energy efficiency. This diploma ensures apprentices develop the precision and craftsmanship needed for long-lasting, weathertight roofs.

    Key Concepts

    Core ideas you must understand for this topic

    • →Roof geometry and terminology: Understanding pitch, rise, span, and roof components such as rafters, battens, underlay, and flashings.
    • →Material selection and preparation: Identifying different types of natural slate (e.g., Welsh, Spanish) and concrete/clay tiles, and knowing how to cut, hole, and fix them correctly.
    • →Fixing methods and gauges: Applying the correct lap, gauge, and fixing pattern (e.g., single lap, double lap) based on roof pitch and exposure conditions.
    • →Health and safety regulations: Complying with Work at Height Regulations 2005, COSHH, and manual handling guidelines, including safe use of ladders and scaffolding.
    • →Weatherproofing and detailing: Installing underlay, battens, flashings, and ventilation components to prevent water ingress and ensure condensation control.

    Learning Objectives

    What you need to know and understand

    • Demonstrate safe use and maintenance of hand and power tools for plain tiling
    • Accurately set out a roof in accordance with gauging and bond requirements
    • Prepare substrates and materials for tiling, ensuring compliance with specifications
    • Cut tiles and associated components to required dimensions using appropriate methods
    • Install plain tiles to a roof slope, achieving correct lap, bond, and fixing
    • Apply tiling to roof details such as ridges, hips, valleys, eaves, and abutments

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly setting gauge for tile size and roof pitch, demonstrating consistent tile spacing
    • Check evidence of safe operation and routine maintenance of cutting tools (guarding, blade condition)
    • Expect neat, accurate cuts without chipping or breakage, with cut edges appropriately dressed or concealed
    • Verify that tiles are properly nailed/clipped at the correct frequency as per manufacturer instructions and wind uplift calculations
    • Look for effective detailing at eaves with correct overhang, verge bedding or dry-fix system, and appropriate underlay integration
    • Assess the overall alignment and bond pattern; deduct for irregular courses or uneven laps

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always double-check your gauge marking before beginning to lay tiles; a small error can compound across the roof
    • 💡In practical assessments, demonstrate a methodical workflow: substrate inspection, setting out, cutting, fixing, detailing
    • 💡Be prepared to explain the purpose of underlay, counter-battens, and eaves ventilation during oral questioning
    • 💡Practice measuring and cutting complex shapes around chimneys or dormers; assessors will look for precision
    • 💡Familiarise yourself with the manufacturer's fixing specification for the tile type being used—this is often a key assessment criterion
    • 💡Always refer to the manufacturer's technical data sheets for fixing specifications. Examiners look for evidence that you can apply industry standards, not just general rules. Mentioning specific British Standards (e.g., BS 5534 for slating and tiling) will earn you extra marks.
    • 💡In practical assessments, pay close attention to your setting out. Accurate gauge marking and aligning tiles/slates along the roof plane demonstrates precision. Use a chalk line and spirit level to ensure straight courses.
    • 💡When answering theory questions, structure your answers using the 'P.E.E.' method (Point, Evidence, Explanation). For example, state the correct fixing method, cite the relevant regulation or standard, and explain why it prevents roof failure.

    Common Mistakes

    Common errors to avoid in your coursework

    • Misinterpreting gauging charts or failing to adjust for roof pitch, leading to incorrect exposure and water ingress
    • Using excessively worn or damaged cutting blades, causing ragged cuts and material wastage
    • Incorrect fixing frequency or type, resulting in tile slippage, rattling, or failure under wind load
    • Neglecting to lay tiles from different pallets uniformly, causing shade variation and poor aesthetics
    • Omitting necessary ventilation or counter-battening in tiled roof systems
    • Applying mortar fillets incorrectly at abutments, leading to cracking and leaks
    • Misconception: All slates and tiles can be fixed using the same nail size and pattern. Correction: Fixing specifications vary by material type, roof pitch, and exposure zone. For example, natural slate requires two nails per slate, while concrete tiles may use one nail and a clip in high-wind areas.
    • Misconception: Underlay is optional for pitched roofs. Correction: Underlay is a mandatory part of a modern roofing system to provide secondary weather protection and allow condensation to escape. Building regulations require it for most new roofs.
    • Misconception: Cutting slates and tiles can be done with any saw. Correction: Using the wrong tool can cause chipping or breakage. Slate requires a slate cutter or a tungsten-tipped blade, while concrete tiles need a diamond-tipped blade to avoid dust and damage.
