Assessment criteria
Topic Overview
The NOCN Level 2 NVQ Diploma in Roofing Occupations (Construction) is a competency-based qualification designed for learners working in the roofing industry. It covers the skills and knowledge required to install, repair, and maintain various roofing systems, including slating, tiling, and sheet metal roofing. This diploma is essential for those seeking to become competent roofers, as it combines practical on-the-job training with theoretical understanding of health and safety, materials, and techniques.
This qualification is part of the Construction & Building Services suite and is recognised by employers across the UK. It ensures that learners can work safely and effectively on construction sites, understanding the importance of weatherproofing, structural integrity, and building regulations. By completing this NVQ, students demonstrate their ability to perform roofing tasks to industry standards, which is crucial for career progression and achieving advanced certifications.
The diploma covers a range of units, from preparing substrates and installing underlay to fixing tiles, slates, and flashings. It also emphasises sustainability and modern methods of construction, preparing learners for the evolving demands of the building industry. Mastery of these skills not only enhances employability but also contributes to the safety and longevity of buildings.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Shingles laid to correct headlap, sidelap and exposure as per manufacturer data and design.
- Fixings (nails/staples) correctly positioned and driven home without splitting the shingle.
- Evidence of reading and following roof plan and specification for material grades, batten spacing and starter course detail.
- Work area left clean and tidy, with all waste segregated and disposed of in line with site environmental rules.
- Personal protective equipment used correctly throughout, and fall prevention measures in place.
- Roof covering completed within the programme timetable, with any delays recorded and justified.
- Accurately interpret roof plans, sections, and specifications to determine shingle type, exposure, fixings, and underlay requirements.
- Select and use correct personal protective equipment (PPE) and access equipment, demonstrating safe working at height in line with the Work at Height Regulations.
- Apply and adjust shingles to maintain consistent headlap, sidelap, and alignment, ensuring weathertightness per manufacturer's instructions.
- Protect finished roof surfaces and adjacent areas from damage using appropriate covers and careful material handling.
- Complete installation within the project timeline, showing efficient sequencing of work and resource management.
- Verify that the completed installation matches the contract specification, including correct fixings, battens, and ventilation details.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always check the specific manufacturer's technical data sheet for the wood shingle type being used; it will detail exposure, fixings and overlap.
- 💡In your evidence portfolio, include photographs or video of critical stages such as setting out, nailing, and final inspection to demonstrate competence.
- 💡For timed assessments, practise the installation process beforehand to improve speed without compromising quality.
- 💡Always begin by thoroughly reviewing project documentation and raising any discrepancies promptly with your supervisor before starting work.
- 💡Demonstrate awareness of sustainability by properly sorting and disposing of offcuts and packaging, as this is assessed in many units.
- 💡Photograph or document each stage of your installation to provide evidence of compliance with specifications, quality checks, and safety measures.
- 💡When being observed, verbalize your decision-making process, such as why you selected specific fixings or adjusted installation techniques for weather conditions.
- 💡Always reference current building regulations and British Standards (e.g., BS 5534 for slating and tiling) in your answers to show up-to-date knowledge.
- 💡Use specific terminology such as 'eaves', 'verges', 'abutments', and 'flashings' to demonstrate technical competence.
- 💡When describing a process, break it down into logical steps (e.g., preparation, installation, finishing) and mention safety checks at each stage.
Common Mistakes
Common errors to avoid in your coursework
- Failing to pre-drill shingles near edges, causing splitting during nailing.
- Using incorrect nail length or gauge, which can compromise holding strength or protrude.
- Neglecting to stagger joints between courses correctly, creating weak points.
- Misinterpreting the starter course detail, leading to misalignment of subsequent courses.
- Not allowing for adequate ventilation beneath the shingles, risking premature decay.
- Misinterpreting exposure measurements leading to uneven courses or insufficient weather protection.
- Failing to properly condition or acclimate wood shingles to the site humidity, causing excessive shrinkage or expansion after installation.
- Incorrect nailing pattern or nail type, resulting in shingle splitting or insecure fixings.
- Neglecting to install adequate underlayment or eave protection, leading to leaks at critical areas.
- Working without a proper scaffold or fall protection, violating health and safety regulations.
- Misconception: All roofing tiles are fixed the same way. Correction: Different materials (e.g., clay vs. concrete tiles) require specific fixing methods and nail sizes to ensure durability and compliance with British Standards.
- Misconception: Underlay is optional for most roofs. Correction: Underlay is a critical layer that provides secondary weather protection; omitting it can lead to leaks and void warranties.
- Misconception: Roofing work doesn't require precise measurements. Correction: Accurate cutting and alignment of tiles and flashings are essential for a watertight finish and aesthetic appearance; errors can cause costly rework.
