A warm roof (for low slope roofs) is “a roof where the roof insulation is installed on top of the structure” i.e. insulated from the outside of the building.
One if the benefits of a thermally efficient warm roof is the transfer of a building's dew point to the outside. This prevents internal dampness of structural materials and negates the need for vents that would normally allow air to escape.
A Viking WarmRoof system is BRANZ appraised (Appraisal No. 713), insuring it meets New Zealand building code requirements.
