CSCS Roof Felting study guide
CSCS Roof Felting · Work through your exam, one topic at a time.
The CSCS Roof Felting certification is a construction-industry credential for workers who install, repair and inspect felt and membrane roofing systems. It signals that a operative can work competently and, above all, safely on flat and low-pitch roofs, where falls, hot-works fires, solvent exposure and manual handling are everyday hazards. The CSCS Roof Felting study guide has 7 sections and about 1,721 words.
01Health, Safety and Welfare in Roof Felting Work
Health and safety questions in roofing felt work test whether you can identify the hazard, name the control, and know the hierarchy that governs it. The candidate must understand the hierarchy of control (eliminate, substitute, engineer, administrate, PPE last), the difference between a hazard and a risk , and the statutory duties owed under construction health and safety law: safe systems of work, competent supervision, welfare provision and consultation.
286 words, about 1 min02Roof Felting Materials, Components and Specifications
Candidates must know the main waterproofing families used in roof felting: bitumen-based membranes (oxidised and polymer-modified, e.g. SBS and APP), reinforcement carriers (polyester, glass fibre, composite), and self-adhesive versus torch-applied versus hot-bitumen fixing methods.
247 words, about 1 min03Preparation, Substrate and Surface Assessment
Before any felt is laid, the substrate must be assessed for soundness , moisture content , flatness , slope , and compatibility with the proposed system. Candidates should understand deck types (timber, concrete, metal, existing felt), the need for vapour control and ventilation , and the role of primers in promoting adhesion.
225 words, about 1 min04Installation of Felting Systems and Waterproofing Layers
Installation follows a defined sequence: vapour control layer , insulation (where specified), underlay(s) , then cap sheet . Candidates must understand side laps and end laps , the staggering of laps between layers, and the direction of water flow so that laps shed water rather than trap it.
242 words, about 1 min05Detail Work: Edges, Upstands, Outlets and Penetrations
Most leaks originate at details , not field membrane. Candidates must know how to form upstands , edge trims , drip edges , verge and eaves details , outlets , rainwater outlets , penetrations , and expansion joints .
239 words, about 1 min06Tools, Equipment and Safe Working at Height
Candidates should recognise gas torches , hot bitumen boilers , rollers , seam rollers , knives , sanders/grinders , moisture meters , and fall-arrest and edge-protection equipment. Understand the safe use, inspection and maintenance of each, and the need for pre-use checks on ladders, harnesses and torches.
238 words, about 1 min07Inspection, Testing, Defects and Repair
Candidates must know how to inspect felt roofs for blistering , wrinkling , ponding , lap failure , cracking , punctures , and detail defects . Testing methods include visual inspection , moisture surveys , flood testing of flat areas, and electronic leak detection where specified.
