Installing trussed rafters requires specific construction skills which involve working at height and handling dynamically unstable materials.

A full site-specific risk assessment must be undertaken before any work commences.

Before you begin:

  • Check and read all assembly drawings and information provided by the truss supplier
  • Ensure all personal protective equipment (PPE) is worn and correctly fitted
  • Ensure scaffolding is in place and signed off
  • A safe working platform within the structure is strongly recommended
  • Ensure hop-ups and scaffolding edge protection are in place
  • After reading the truss layout drawings, identify the easiest starting point using the simplest roof of trusses.
