What is a cold roof?

  • A cold roof either has no insulation or the principal insulation is at ceiling level
  • This results in the roof covering and structural deck being COLDER than the building’s interior in winter
  • Condensation is controlled by wind-induced ventilation and
    vapour resistant layers
  • It is essential to ventilate the roof void of cold roofs
  • Condensation calculations should not be used for cold roof constructions
