Spray-on Foam Roof Insulation has been much criticised for its problems.


Problems

  • Does not permit water drainage or evaporation
  • No air gap between insulator & tiles/slates to allow airflow for drying
  • Increases chances of structural timber rot, and repacing a timber roof structure isn't cheap.
  • No ability to inspect timbers after insulation is sprayed
  • Prevents re-use of roof covering. This creates an additional expense & in some cases renders historic fabric unreusable.
