Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately interpreting drawings, specifications, and manufacturer guidelines to determine tile layout, underlay, batten spacing, and fixings.
- Award credit for demonstrating compliance with health and safety legislation, including proper use of PPE, fall protection, and safe handling of materials.
- Award credit for selecting appropriate tools and materials, checking quality and quantity against project requirements, and minimising waste.
- Award credit for protecting the work area and surrounding property from damage, using dust sheets, debris netting, and careful material storage.
- Award credit for completing the installation within the allocated time, maintaining quality and efficiency throughout.
- Award credit for correctly interpreting drawings, schedules, and manufacturer instructions to establish batten gauge, lap, and fixing patterns.
- Demonstrate safe and correct handling, storage, and selection of plain tiles, ensuring only sound tiles are used and mixed from pallets to prevent colour banding.
- Evidence accurate setting out and fixing of underlay, battens, and tiles to the required exposure, with nails fully driven and correctly positioned.
- Show compliance with relevant legislation (e.g., Work at Height Regulations, CDM) and codes of practice (BS 5534) through risk assessments and method statements.
- Minimise damage by protecting roof edges, using appropriate access equipment, and cleaning up as work progresses.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference manufacturer's fixing instructions and BS standards in your portfolio evidence to demonstrate knowledge compliance.
- 💡Use photographic evidence with annotations to show key stages: setting out, underlay installation, batten spacing, tile fixing, and completion.
- 💡In time-constrained assessments, plan your work sequence to avoid delays; pre-assemble tools and materials before starting each section.
- 💡For observed assessments, verbally explain your actions to the assessor to showcase underpinning knowledge of why you are doing tasks a certain way.
- 💡Build a comprehensive portfolio with annotated photographs, witness testimonies, and copies of relevant risk assessments and material specifications.
- 💡Cross-reference each piece of evidence to the specific learning outcomes and assessment criteria to make the assessor’s job easier.
- 💡During professional discussions, be prepared to explain the reasoning behind your choices, such as product selection or method adjustments, referencing British Standards and manufacturer guidance.
- 💡Show awareness of environmental considerations like waste management and recycling of packaging materials.
- 💡Ensure time-bound evidence includes accurate job records with dates and durations, clearly demonstrating completion within allocated timeframes.
- 💡Tip 1: When providing evidence for your portfolio, include clear photographs with annotations showing specific details like nail positions, overlaps, and lead welds. This demonstrates your attention to detail and understanding of best practices.
- 💡Tip 2: Know your terminology. Use correct technical terms (e.g., 'headlap', 'gauge', 'soakers') in your written answers and discussions with assessors. This shows you have mastered the subject knowledge.
- 💡Tip 3: Always reference health and safety in your evidence. For example, when describing a task, mention the PPE used, any risk assessments carried out, and how you ensured a safe working environment. This is a key assessment criterion.
Common Mistakes
Common errors to avoid in your coursework
- Incorrect batten spacing leading to uneven tile courses or insufficient lap, compromising watertightness.
- Failing to properly bed or mechanically fix tiles at eaves, verges, and ridges, resulting in wind uplift or leaks.
- Neglecting to check and set out tile gauge accurately across the roof slope, causing misalignment at abutments.
- Misinterpreting the specification and using wrong tile type or color, requiring rework.
- Poor housekeeping and waste management, leading to site accidents or material contamination.
- Misinterpreting the headlap or side lap requirements, leading to insufficient weatherproofing or uneven courses.
- Failing to properly sort and grade plain tiles, resulting in inconsistent appearance or weak areas due to defective tiles.
- Neglecting to secure perimeter tiles with additional fixings as specified, causing vulnerability to wind uplift.
- Incorrect nailing technique, such as under-driven nails damaging tile nibs or over-driven nails splitting the batten.
- Not adjusting gauge for roof pitch or length, causing tiles to not align at ridge or eaves.
- Misconception: 'All roofing materials can be installed the same way.' Correction: Different materials (e.g., natural slate vs. concrete tiles) require specific fixing methods, batten gauges, and headlap distances to ensure performance and compliance with British Standards.
- Misconception: 'Health and safety is just paperwork.' Correction: It is a practical, ongoing process that involves risk assessments, method statements, and daily checks to prevent accidents. Ignoring it can lead to serious injuries or fatalities.
- Misconception: 'Lead work is optional for roofers.' Correction: Lead flashings are essential for weatherproofing complex areas like chimneys and valleys. Proper lead welding and dressing techniques are core skills assessed in this NVQ.
