What does New Denim Blue look like on a house?
NZ Steel calls it a deep, calming blue that sits as easily on traditional homes as contemporary ones. Its LRV is 11%, so from the street it reads dark rather than bright.
Blue is a bolder call than grey. In our view it works when something else picks it up: white weatherboards, natural timber, or a seaside spot where the water does the matching.
Before you commit to a blue roof
- Get a real sample sheet. NZ Steel says its on-screen colours vary from the actual product
- Look at it outside on a clear day and again on an overcast one
- Hold it beside your cladding and front door, standing on the ground
- Settle the spouting (gutters), fascia and flashing colours at the same time
How warm does a blue roof run?
The higher a colour's TSR, the more heat it reflects and the cooler the roof stays. At 24%, this blue sits with the darker colours, a long way below a white like Cloud at 69%. If you're re-roofing, look at roof insulation and underlay at the same time.
Near the sea or in a geothermal area
Like every COLORSTEEL colour, New Denim Blue is made in MAXAM and ALTIMATE. Within 100 metres of saltwater, NZ Steel asks you to contact COLORSTEEL to confirm the warranty, and it wants the same call from anyone building near geothermal activity. Leave the product choice to your roofer and NZ Steel.
Our take
If you keep coming back to blue, go for it, but get certainty first. Prop a sample sheet against the house for a week and look at it from the footpath each day. We're an independent referral service with no tie to New Zealand Steel, and when you're ready we'll pass the job to one checked roofer.
