Maintain slate and tile roofing
This element covers the essential skills and knowledge required to carry out maintenance on slate and tile roofing systems, including preparation, replacement of battens and underlay, and the renewal of slates, tiles, and associated components. It also encompasses the removal and replacement of rainwater goods, ensuring the roof remains weathertight and functional. Learners develop competence in safe access, material identification, and correct fixing techniques aligned with industry standards.
Assessment criteria
Topic Overview
The Cskills Awards Level 2 Diploma in Craft Masonry (Construction) (QCF) is a vocational qualification designed for individuals seeking to become skilled stonemasons. This diploma covers essential practical and theoretical aspects of craft masonry, including stone identification, cutting, shaping, and fixing. Students learn to work with different types of stone, use hand and power tools safely, and interpret technical drawings to produce high-quality masonry work. The qualification is part of the NOCN Group's Vocationally-Related Qualification framework, ensuring it meets industry standards and prepares learners for employment or further study in construction and heritage restoration.
This diploma is crucial for anyone aiming to work in the construction industry, particularly in roles that require precision and craftsmanship. Masonry is a fundamental skill in building and restoring structures, from modern commercial buildings to historic monuments. By completing this qualification, students gain a recognised credential that demonstrates their competence to employers. The course also emphasises health and safety, sustainability, and teamwork, which are vital in real-world construction environments. Understanding craft masonry not only opens doors to careers as a stonemason but also provides a foundation for specialising in areas like stone carving, conservation, or site supervision.
Within the wider subject of Construction & Building Services, craft masonry is a specialised trade that contributes to the structural integrity and aesthetic appeal of buildings. This diploma integrates with other construction disciplines, such as bricklaying, carpentry, and civil engineering, to create a holistic understanding of the built environment. Students learn how masonry fits into the construction process, from foundation work to finishing details. The qualification also aligns with modern construction practices, including the use of sustainable materials and digital tools for design and measurement, ensuring graduates are equipped for contemporary industry demands.
Key Concepts
Core ideas you must understand for this topic
- →Stone identification and classification: Understanding the properties of different stone types (e.g., limestone, sandstone, granite) and their suitability for various applications, including durability, workability, and weathering characteristics.
- →Setting out and measuring: Accurately interpreting technical drawings and using tools like tape measures, levels, and squares to mark out stone for cutting and positioning, ensuring precision in dimensions and alignment.
- →Cutting and shaping techniques: Using hand tools (chisels, hammers) and power tools (angle grinders, stone saws) to cut, shape, and finish stone to required specifications, including techniques for creating straight edges, curves, and decorative features.
- →Mortar mixing and application: Preparing mortar mixes with correct proportions of cement, lime, sand, and water, and applying them to bond stones securely, considering factors like strength, colour, and weather resistance.
- →Health and safety regulations: Adhering to COSHH, manual handling, and PPE requirements specific to masonry work, including safe use of tools, dust control, and working at height.
Learning Objectives

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating systematic preparation, including site inspection, material identification, and tool selection.
- Evidence of correct replacement of battens and underlay, ensuring alignment, overlaps, and secure fixing in accordance with manufacturer’s instructions.
- Award credit for accurate replacement of slates and tiles, maintaining appropriate headlap, side lap, and using correct nails or clips.
- Demonstrate safe removal and replacement of rainwater goods, ensuring correct falls, secure brackets, and watertight seals.
- Show consistent application of health and safety practices, especially when working at height, including correct use of PPE and access equipment.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference the assessment criteria with your photographic evidence to ensure each step is captured clearly.
- 💡Include a risk assessment and method statement in your portfolio to showcase thorough preparation.
- 💡When replacing tiles or slates, document your verification of headlap and nail penetration to prove compliance with standards.
- 💡For rainwater goods, demonstrate testing for leaks and correct flow after installation as part of functional checks.
- 💡Always show your working out in calculations for setting out and quantity estimation. Examiners award marks for correct methodology even if the final answer is slightly off due to arithmetic errors. Clearly label dimensions and use diagrams where appropriate.
- 💡In practical assessments, prioritise safety and accuracy over speed. Examiners look for correct use of PPE, safe tool handling, and adherence to specifications. Rushing often leads to mistakes in measurements or cuts, which can cost marks.
- 💡When answering theory questions, use technical terminology correctly (e.g., 'bed joint', 'perpend', 'quoin') and relate your answers to real-world applications. For example, explain why a particular stone type is chosen for a specific part of a building, linking to properties like compressive strength or aesthetics.
Common Mistakes
Common errors to avoid in your coursework
- Misidentifying the type of slate or tile, leading to incorrect replacements and mismatched appearance.
- Failing to check and adjust the headlap when replacing slates, causing potential water ingress.
- Neglecting to overlap or tape underlay correctly at joints, compromising the roof’s secondary weather barrier.
- Installing rainwater goods without the correct fall, resulting in standing water or leaks.
- Overlooking the condition of fixings and battens when removing old coverings, missing hidden rot or corrosion.
- Misconception: All stones are the same and can be used interchangeably. Correction: Different stones have varying properties like hardness, porosity, and frost resistance. Using the wrong stone can lead to structural failure or rapid deterioration. For example, soft limestone is unsuitable for high-traffic areas, while granite is ideal for heavy loads.
- Misconception: Mortar is just for sticking stones together. Correction: Mortar also accommodates movement, prevents water ingress, and contributes to the overall strength of the structure. The mix ratio must be chosen based on the stone type and environmental conditions; too strong a mortar can damage softer stones.
- Misconception: Cutting stone is purely about strength and force. Correction: Precision cutting requires understanding the stone's grain and using appropriate techniques to avoid cracking. For example, scoring a line before cutting reduces the risk of breakage, and using a chisel at the correct angle ensures a clean edge.
