Strip and reclaim pitched roof coverings
This subtopic focuses on the systematic removal and potential reuse of pitched roof coverings, requiring safe access, weather protection, and methodical stripping of single-lap tiles, plain tiles, and natural slates. Learners must demonstrate competence in handling materials to prevent damage, sorting for reclamation, and storing or disposing of waste in line with environmental and site requirements. This skill is essential for refurbishment projects, promoting sustainability and cost-efficiency by recovering materials for reuse while maintaining structural integrity.

Topic Overview
The NOCN Level 2 Diploma in Roof Slating and Tiling (Construction) is a vocational qualification designed for learners who want to become skilled roof slaters and tilers. This diploma covers the essential knowledge and practical skills required to install, repair, and maintain roofs using natural slates, artificial slates, and clay or concrete tiles. You will learn about health and safety regulations, roof geometry, underlay installation, battening, and the correct methods for fixing different roofing materials. The course also includes understanding weatherproofing, ventilation, and the principles of roof drainage to ensure long-lasting, watertight roofs.
This qualification is part of the Construction & Building Services sector and is recognised by employers across the UK. It prepares you for roles such as a roof slater/tiler, roofing contractor, or site supervisor. Mastering these skills is crucial because roofs protect buildings from the elements and contribute to energy efficiency. The diploma combines classroom theory with hands-on workshop practice, ensuring you can apply your knowledge safely and effectively on real construction sites. By the end, you will be able to interpret technical drawings, select appropriate materials, and work to industry standards like BS 5534 and the NHBC standards.
In the wider context of construction, roof slating and tiling is a specialised trade that requires precision and attention to detail. Poorly installed roofs can lead to leaks, heat loss, and structural damage. This diploma not only teaches you the techniques but also instils a strong safety culture, covering working at height, manual handling, and use of personal protective equipment (PPE). It is an ideal stepping stone to advanced qualifications like the Level 3 Diploma or an apprenticeship, and it opens doors to self-employment or employment with established roofing companies.
Key Concepts
Core ideas you must understand for this topic
- →Roof geometry: Understanding pitch, rise, span, and how to calculate roof areas for material estimation.
- →Underlay and battens: Correct installation of breathable membranes and treated timber battens to support slates/tiles and allow ventilation.
- →Fixing methods: Using nails, clips, and hooks for slates; nibs and nails for tiles; and understanding headlap and side lap for weatherproofing.
- →Eaves, ridges, and valleys: Detailing at roof edges, junctions, and changes in pitch to prevent water ingress.
- →Health and safety: Working at height regulations, ladder safety, scaffold use, and COSHH for adhesives and treatments.
Learning Objectives
What you need to know and understand
- Know how to access roofs for stripping and reclaiming roof products, Be able to access roofs for stripping and reclaiming roof products., Know how to protect roofs when stripping roof areas, Know how to remove and reclaim single-lap roof coverings, plain tiles and regular sized natural tiles., Be able to remove and reclaim single-lap roof coverings, plain tiles and regular sized natural tiles., Know how to store and dispose of materials., Be able to store and dispose of materials.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct selection, inspection, and safe erection of access equipment (e.g., roof ladders, scaffolding) in compliance with method statements and manufacturer instructions.
- Award credit for effectively protecting the roof structure and interior from weather by deploying temporary coverings (e.g., tarpaulins) before and during stripping operations.
- Award credit for systematically removing roof coverings without causing unnecessary damage – for single-lap tiles, plain tiles, and natural slates – using appropriate hand tools and techniques.
- Award credit for correctly sorting reclaimed materials, separating reusable items from waste, and stacking or palletizing them to avoid breakage.
- Award credit for following waste management procedures, including segregation of hazardous materials (e.g., asbestos-contaminated debris), safe disposal in designated skips or containers, and cleaning the work area on completion.
Assessment Guidance
Guidance for achieving higher grades
- 💡In practical assessments, narrate your risk assessment and decision-making process to demonstrate underpinning knowledge, especially when choosing access methods and protective measures.
- 💡Photograph your stripping process in stages – this evidence can support your portfolio by showing systematic removal, sorting, and safe storage.
- 💡Always refer to the relevant Health and Safety Executive (HSE) guidance and manufacturer instructions when explaining your approach, as this demonstrates current industry compliance.
- 💡When reclaiming natural slates, handle them by the edges to prevent delamination, and show you can grade them by size and thickness if re-laying is part of a larger project.
- 💡Always show your working for material calculations. Examiners award marks for correct formulas even if the final number is slightly off. For example, write down 'Number of slates = (roof area) / (slate width × gauge) × 2'.
- 💡Know your British Standards. Mentioning BS 5534 (slating and tiling) and BS 8000-6 (workmanship) in written answers shows depth of knowledge and can earn extra marks.
- 💡In practical assessments, focus on safety checks first. Always inspect your ladder, scaffold, and PPE before starting. Examiners look for a methodical approach and risk awareness.
Common Mistakes
Common errors to avoid in your coursework
- Assuming existing roof access is safe without performing a pre-use inspection of ladders or scaffolding, leading to falls or instability.
- Neglecting to secure temporary weather protection, causing water ingress and damage to the building during overnight or wet weather.
- Mixing different types of reclaimed tiles or slates without checking compatibility, which can result in an unsightly or functionally compromised reinstalled roof.
- Disposing of all materials as general waste rather than identifying reclaimable items, missing opportunities for reuse and increasing project costs.
- Underestimating the weight and fragility of stacked reclaimed materials, leading to unsafe manual handling and breakage.
- Misconception: All slates are the same size and can be fixed identically. Correction: Slates come in various sizes (e.g., 500x250mm, 600x300mm) and require different lap calculations. Always refer to manufacturer specifications and BS 5534 for correct headlap.
- Misconception: Underlay is optional if tiles overlap well. Correction: Underlay is essential as a secondary weatherproof layer. Even with overlapping tiles, wind-driven rain can penetrate. Underlay also provides temporary protection before tiling.
- Misconception: Nailing every tile is always best. Correction: Over-nailing can crack tiles. Use the correct number and type of fixings per tile (e.g., two nails for plain tiles, one for interlocking). Some tiles rely on nibs and only need nails at vulnerable areas like verges.
