CSCS Roof Felting case studies
CSCS Roof Felting · Put your knowledge to work in context.
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. Candidates are typically roofers, waterproofing operatives, labourers moving into felt work, or supervisors who need to verify their team's knowledge. The assessment is multiple choice and samples the whole trade: health, safety and welfare; materials and specifications; substrate and surface assessment; installation of felting and waterproofing layers; detailing at edges, upstands, outlets and penetrations; tools and safe working at height; and inspection, defect diagnosis and repair. The CSCS Roof Felting case studies are 5 cases and about 2,606 words.
