Already available

  • Installation contract
  • Product or system identification
  • Warranty or guarantee information
  • Photographs from installation
  • Current loft photographs
  • Previous survey or independent report
  • Roof, ventilation or moisture records
  • Written lender or valuer request
  • Listed or protected-building status

Ask the installer or previous owner

  • Ask the installer or previous owner for the installation contract.
  • Ask the installer or previous owner for the product and system details.
  • Ask the installer or previous owner for the warranty or guarantee documents.
  • Ask whether before, during or after installation photographs exist.

Ask an independent assessor or relevant professional

  • Ask an independent professional what can be recorded safely; do not enter an unsafe loft.
  • Ask an independent assessor what inspection or report is appropriate.
  • Ask an independent assessor which roof, ventilation or moisture records are relevant.
  • Confirm status and permissions with the relevant authority or qualified professional.

Ask the named lender or valuer

  • Ask the named lender or valuer to state its requirements in writing.

Limits of this checklist

  • does not inspect or diagnose the property;
  • does not determine whether removal is required;
  • does not guarantee lending, sale or valuation outcomes;
  • does not calculate a price; and
  • has not submitted or stored the homeowner's selections.

Why these records are useful

RICS recommends retaining installation details, calculations, roof-work information, warranties or guarantees, independent certificates where relevant, and photographs and condition records from before, during and after work. The checklist turns missing items into questions rather than treating them as defects.

What the checklist does

Tick only whether a record is already available. The tool groups missing items by the person best placed to answer the question and keeps every selection in this page session.

What it cannot decide

The checklist does not inspect the roof, determine whether removal is required, predict lending, calculate a price or send data. Cornwall Council states that some installations do not require removal and that removal does not guarantee mortgage approval.
