COLORSTEEL coloursHow each one looks, and how much heat it reflects.
NZ Steel's colour selector lists 24 COLORSTEEL colours. Each page below covers what the colour looks like, its heat figures, the finishes it comes in and the houses it suits. Start with the group closest to what you have in mind.
Where to start
Dark charcoals and greys are where most people look first. NZ Steel says Grey Friars, Ironsand, FlaxPod and Ebony remain favourites across New Zealand. Compare Grey Friars, Slate, Windsor Grey, Ironsand, FlaxPod and Ebony.
Lighter colours such as Cloud, Titania and Gull Grey reflect far more heat. For greens, reds and blue, see Karaka, Pioneer Red and New Denim Blue.
Matte colours have a textured, ultra-low gloss surface. There are three: FlaxPod Matte, TidalDrift Matte and StonePeak Matte.
Finishes and heat in a nutshell
Classic is the original finish. Low Gloss is softer and reduces reflectivity: Sandstone Grey, Grey Friars, Ironsand, Ebony and FlaxPod come in both, and Windsor Grey is Low Gloss only.
Every colour has a TSR (total solar reflectance) and an LRV (light reflectance value) from NZ Steel. The higher the TSR, the more of the sun's heat the roof reflects and the cooler it stays. Cloud is highest at 69% and Ebony lowest at 5%.
Before you choose
Every colour comes in COLORSTEEL MAXAM, for most of New Zealand, and ALTIMATE, for extreme marine and other harsh sites. Your roofer should confirm which one suits your address, especially near the sea or geothermal activity.
Screens show colour differently, so order a sample sheet and look at it outdoors before you decide. You can also try a few on a house with the colour visualiser, and read about the material itself on our COLORSTEEL roofing page.
