Let’s talk roof colour…
Which roof colour you choose can make a big difference to the overall comfort of your home. Light coloured roofs can reflect up to 70% of summer heat gain. According to YourHome.gov.au, this is around 50% more than a dark roof. According to Dulux, this has the potential to reduce rooftop surface temperatures by as much as 20–35°C.
After reflecting the sun’s heat away from the building, the measure of how much leftover heat has been absorbed is called ‘solar absorptance’ (SA) and it’s measured on a scale of 0 to 1. If the SA value of a roofing product is near to 1, this means it will absorb more heat into the building than a roof product that is nearer to 0.
