Roof insulation — Roofer

State whether the loft is unheated storage or occupied accommodation, and share photographs of access and the existing insulation. Mention roof leaks, condensation or planned conversion work. These details help establish where insulation belongs before comparing material types or quantities.

Service scope

Insulation work within a roof or loft assembly, selected according to where the thermal boundary belongs and how the roof manages moisture. The service distinguishes loft-floor insulation from rafter-level or flat-roof work and includes only the agreed access and finishing interfaces.

What is normally included

  • Assessment of the intended insulation zone
  • Installation of a specified compatible insulation system
  • Attention to agreed access and ventilation interfaces

What is not included

  • Guaranteed energy savings
  • Blocking intentional ventilation or covering unresolved leaks

Typical tasks

  • Assess the existing roof and insulation arrangement
  • Identify the proposed thermal boundary
  • Review moisture and ventilation interfaces
  • Install the agreed insulation scope
  • Record access and follow-on finishing requirements

What to include in your brief

  • Loft or roof use
  • Existing insulation information
  • Roof condition and moisture concerns
  • Access and service obstructions
  • Proposed insulation or conversion plans

Choosing the right professional

Ask the provider to explain the roof build-up and ventilation strategy, not only a material thickness. Confirm what happens around access hatches, storage, services and areas that cannot be reached safely.

Important considerations

  • Insulation changes moisture behaviour within the roof
  • Existing leaks or poor ventilation require assessment
