Are you wondering what colour roof reflects the most heat?
Well, generally speaking lighter colours are better at reflecting the sun’s radiation away from the surface, with white being the colour that absorbs the least heat.
So, if you’re considering a roof restoration or building a new home, what colour should you choose?
In this blog, you’ll find our pick of the best roof shades for reflecting the sun – from light colours, to terracottas, greens, greys and more.
We recommend that you evaluate the heat reflective abilities in conjunction with the aesthetic or colour palette you had in mind for your home.
How to Determine If A Roof Coating is Heat Reflective
The single best way to evaluate heat reflective capability is to look at the total solar reflectance (TSR) figure which is displayed as a percentage for a product. The higher the percentage (closer to 100%), the better the coating is at reflecting the sun’s radiation away from the surface.
In our product recommendations below, you’ll see the TSR values listed for both Infracote and Elastacote – two of our coatings proven to meet the Australian and New Zealand standards (AS/NZS 4858 and AS 4654) for coatings of this kind.
Infracote is our specialised heat reflective coating hence you’ll see higher TSR % than the equivalent colour in Elastacote.
