Surface temperature as indication of heat loss
• roof temperature depends on a number of factors
• major factors: quality of insulation and indoor temperature
• minor factors (roof material, construction method, angle, etc)
• individual factors (e.g. downlights, extract fans, etc)
• indication only!• to raise awareness and assist.
Next steps:
• Check quality of roof insulation (see check list http://www.energywise.govt.nz/node/3399
