Topic Synopsis
This topic covers interpreting information, complying with legislation, maintaining safety, selecting resources, minimising damage, completing work on time, and meeting specifications when stripping and reclaiming roof coverings. It is part of the Highfield Level 2 NVQ Diploma in Roofing Occupations – Heritage Roof Slater.
Key Concepts & Core Principles
- Slate grading and selection: Understand how to assess slate quality (e.g., durability, colour, texture) and match it to the existing roof for aesthetic and structural consistency.
- Traditional fixing methods: Master techniques like double-lapping, using tingles (metal strips) for slipped slates, and nailing with non-ferrous fixings (e.g., copper) to prevent corrosion.
- Breathability and ventilation: Heritage roofs must allow moisture to escape; avoid modern vapour barriers that trap damp, leading to rot.
- Conservation principles: Work in a way that minimises damage to original fabric, using like-for-like materials and reversible methods where possible.
- Health and safety for heritage sites: Manage risks like fragile roofs, asbestos in old materials, and working on uneven or steep pitches typical of historic buildings.
Exam Tips & Revision Strategies
- Check weather forecasts before starting.
- Use appropriate lifting techniques.
- Label reclaimed materials clearly.
- Include a detailed method statement in your portfolio, referencing specific control measures for risks identified.
- Use annotated photographs to clearly show the condition of materials before and after stripping, and any protection measures in place.
- Keep a log of time spent on each stage to demonstrate how you met the programme requirements.
- Ensure witness testimonies specifically mention your ability to minimise damage and comply with specifications.
- Reference the specific clauses from the contract or specification that relate to reclamation in your evidence write-ups.
Common Misconceptions & Mistakes to Avoid
- Incorrect handling of heritage materials.
- Inadequate fall protection.
- Poor waste segregation.
- Failing to conduct a pre-work survey to identify hazardous materials (e.g., asbestos) before stripping begins.
- Overlooking the sorting of reclaimed materials, leading to mixed waste and increased disposal costs.
- Causing damage to roof battens or underlay when removing tiles aggressively.
Examiner Marking Points
- Interpret work instructions and drawings.
- Follow safe working practices at height.
- Select correct tools and materials.
- Strip and reclaim materials without damage.
- Complete work to specification and on time.
- Accurate interpretation of project documentation to identify salvageable materials and methods.
- Correct and consistent use of PPE and safe access equipment, with evidence in reflective accounts or witness testimony.
- Demonstration of techniques that avoid unnecessary damage to tiles or slates during removal.
