ExploreAbout this exam
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. Questions test applied judgement rather than memorised trivia, so expect scenarios about laps, bonding methods, weather limits and what to do when a substrate is damp. Preparation works best in layers: revise health and safety and working at height first, because those themes recur across every other domain, then materials and installation, then detailing and repair. Combine reading with hands-on practice and your employer's method statements and risk assessments. The awarding body publishes current test arrangements, so check its official site for the latest information rather than relying on second-hand figures.
What you'll study
About CSCS Roof Felting preparation
What is the CSCS Roof Felting test actually for?
It demonstrates that you know the felt roofing trade and can work safely. Many sites require a valid CSCS card, and the trade test is part of showing occupational competence for roof felting rather than general labouring.
What format are the questions?
Multiple choice, delivered on a computer or tablet at a test centre. Each question has one correct answer from a short list. Some are direct recall, but many are short scenarios asking what you would do or which material is suitable.
How long is the test and how many questions?
The official body sets and periodically revises the number of questions and the time allowed, so check its website for the current figure before you book. Don't plan your revision around numbers quoted by other candidates, as they change.
What score do I need to pass?
The pass mark is set by the awarding body and can change between versions of the test. The current requirement is published on its official site. Aim to be confident across all topic areas rather than targeting a bare margin.
How hard is it?
Straightforward if you have site experience, because most questions reward practical judgement. People fail by underestimating the safety content or by guessing on materials. Read each question fully; several options are plausible until you notice a word like 'first' or 'not'.
What are the most common failure points?
Health and safety questions, especially working at height, hot works and solvent hazards. Also lap directions, bonding methods, weather limits for adhesive and torch work, and detail sequencing at upstands and outlets. Candidates with narrow experience often stumble on systems they have not installed.
In what order should I study?
Start with health, safety and welfare, then tools and safe working at height, because these themes appear throughout. Move to materials and specifications, then substrate assessment, installation, detailing, and finally inspection and repair. Finish with practice questions under timed conditions.
Can I retake it if I fail?
Yes, resits are normally possible, but the waiting period, number of attempts and any additional fee are set by the awarding body. Confirm the current retake rules on its official site or with the test centre when you book.
How long is the certificate valid?
Validity is set by the scheme, not by the test centre, and card and certificate periods can differ. Check the official CSCS guidance for the current validity period and renewal requirements so your card does not lapse on site.
How should I prepare in the final week?
Re-read your employer's method statements and risk assessments, review manufacturer instructions for the systems you fit, and work through practice questions on safety and detailing. Get a good night's sleep; fatigue causes more errors than gaps in knowledge.
