Colorbond roofing at a glance
Colorbond is a pre-painted steel roofing product made by BlueScope and widely used on Australian homes. On this site, Colorbond roofing covers new roofs on extensions and new builds, re-roofs of old steel or tile roofs, and replacement after asbestos removal, across Newcastle and Lake Macquarie. Work is arranged through independent local roofing contractors after a free inspection and written quote.
Why it is so common here
- Light weight. It suits older frames and lowers the load on the house.
- Long sheets. Fewer laps means fewer places for wind-driven rain to get in.
- Colour range. Lighter colours help in summer; darker ones suit some styles.
- Solar compatibility. Mounting panels on steel is straightforward.
- Low maintenance. No ridge pointing or broken tiles.

Getting the grade right for the coast
Newcastle's beaches, harbour and lake make exposure a real decision. The manufacturer grades its steel for different environments, and the warranty can depend on using the right product for the site's distance from breaking surf or other corrosive sources. A coastal house in Merewether or Stockton may need a different product from one in Wallsend or Cardiff. Ask each contractor what they are quoting and get it named on the quote.
Fixings and flashings need to match. Screws of the wrong class corrode before the sheet does, and flashings in a different metal can cause galvanic corrosion.
Colour, heat and neighbours
Colour affects how much heat the roof absorbs. Lighter colours keep roof spaces cooler in summer, which helps with comfort and cooling bills. Very light, glossy roofs can cause glare for neighbours on hillsides, which is worth considering in suburbs where houses look down on each other. Heritage conservation areas and some estates control colours, so check with the council before choosing.
Profiles
- Corrugated: the classic wave, suits most houses and many heritage streetscapes
- Trapezoidal and ribbed profiles: stronger, cleaner lines; suit lower pitches, skillions and commercial roofs
- Concealed-fix and standing seam: no exposed screws; usually used for architectural or very low-pitch work
Underneath the sheets
Pre-painted steel performs best with an anticondensation blanket or foil sarking underneath, which controls condensation, reduces rain noise and adds some insulation. Battens should be steel or timber at the spacing the profile and wind exposure require.
Where Colorbond goes on Newcastle houses
Pre-painted steel turns up on almost every type of house here. On interwar bungalows and Federation cottages, corrugated in a muted traditional colour is often the choice where heritage controls allow steel. On post-war fibro cottages, it is the usual replacement after licensed asbestos removal. On 1980s brick veneer homes around the lake, it replaces failing concrete tiles in a tile to metal conversion. On new extensions and granny flats, it matches or contrasts with the main roof.
Each setting raises slightly different questions: matching an existing profile, choosing a colour that suits the street, or detailing the junction between a new steel roof and an old tile one. Raise them at the inspection.
Questions worth asking at the inspection
- Which product and grade are you quoting, and does it suit my distance from the coast?
- What profile, and is my roof pitch above its minimum?
- Will there be an anticondensation blanket, and what is its rating?
- Which screws and flashings will you use?
- How will you manage swarf during installation?
