COLORBOND steel roof on The Block 2025
On top of The Block

For the ninth year in a row on The Block, COLORBOND® steel has played an important role in helping the teams produce some very impressive properties. And they went all the way to Daylesford to do it!

On the first week of The Block, contestants got a glimpse of the houses and the journey they were about to embark on. Thanks to the properties being partially constructed with a COLORBOND® steel roof and TRUECORE® steel frames. Contestants had to choose their homes using one of the only distinguishing features - the COLORBOND® steel colour, roof style and profile. But beyond its beauty, there are many reasons COLORBOND® steel was the material of choice for these luxury properties.

This year’s roofs, guttering, downpipes, garage doors, sheds and water tanks all feature COLORBOND® steel, with an eye-catching assortment of beautiful colours from the extensive COLORBOND® steel range.

Colour choices

This year was the first time all the houses have been completely built from scratch - all with the same basic footprint (and a very big one at that) but with pitched roofs on three of them and flat roofs on the other two. In each case, the choice of roof colour was a big influence on the rest of the exterior, something to keep in mind when you’re building your own. Maybe you’re a fan of “colour drenching” like House 1’s Monument® Matt roof teamed with dark external walls. Or perhaps you prefer a contrasting colour palette like House 3, with its roof made of COLORBOND® steel in a soft, modern Surfmist® colour teamed with walls of timber and stone. The combinations really are endless - check out the Colours of The Block for the different combinations or explore all 22 colours in the range.

Light and strong

One of the great things about a roof made from COLORBOND® steel is that it is both light and strong. That light weight can have a big impact on the structure that’s holding up the roof - giving you more flexibility in your layout and design choices. A light weight and strong roof could mean you need fewer trusses, which means bigger spaces between the trusses. These bigger spaces allow you to have more skylights, and bigger ones. You’ll quickly see some spectacular results of that being brought to life on each this year’s Block houses. When building, it's a good idea to have a plan on these key features and discuss with your builder. If you looking for a builder, the supplier locator is a great place to start.

Lower angles

The strength and lighter weight of a roof made from COLORBOND® steel can also be a big advantage when building flat roofed houses, as you’ll see on House 2 and 4. The pitch of the roof can be much lower with COLORBOND® steel – it can be a gradient as low as 1 degree. Other roofing materials are usually restricted to a minimum angle of 15 degrees. Flat roofs are enjoying a bit of a comeback in Australia (we love a bit of stylish retro), with skillion roofs in particular introducing added ventilation and extra light from horizontal banks of windows stepped between roof sections at different levels.
