What?

Why?

Prevent fatal fallsFalls from roofs are the number one killer in UK construction.
Fragile surfacesWorkers fall through roof lights and fragile sheets due to inadequate assessment.
Legal requirementWork at Height Regulations require documented assessment for all roof work.
Control selectionThe assessment determines whether edge protection, nets, or harnesses are needed.
Do Don't
  • Complete a roof work risk assessment before anyone accesses the roof.
  • Identify all fragile surfaces, roof lights, and unprotected edges.
  • Specify collective protection measures as the first choice.
  • Plan safe access and egress routes to and from the roof.
  • Include a rescue plan for anyone who may fall.
  • Check weather conditions and set stop-work criteria for wind and ice.
  • Brief all roof workers on the assessment findings before starting.
  • Review the assessment if the work area or conditions change.
  • Ensure all roof workers are trained and competent for the task.
  • Confirm all control measures are in place before permitting access.
  • DON'T access any roof without a completed risk assessment.
  • DON'T assume a roof surface is non-fragile without checking.
  • DON'T rely on harnesses as the first control — use collective protection.
  • DON'T carry out roof work in high winds, heavy rain, or icy conditions.
  • DON'T allow roof access without briefing workers on the hazards.
  • DON'T use a generic assessment — it must be specific to each roof.
  • DON'T store excessive materials on the roof without checking load capacity.
  • DON'T work near unprotected edges without edge protection installed.
  • DON'T skip the rescue plan — falls need immediate planned response.
  • DON'T let unqualified workers carry out any roof work.
