Colorbond vs tile roof in Brisbane: which to choose when you re-roof

Published 23 October 2026

Colorbond vs tiles at a glance

Colorbond steel and roof tiles compared

Monier product pages (November 2025) and FAQ (September 2026); Lysaght Custom Orb page; colorbond.com colour pages (thermal values published August 2022) and FAQ (September 2026); checked 23 October 2026. “Much lighter” is our description; we haven’t been able to re-check a steel sheet weight.

Weight, battens and tie-down

Tiles are heavy. Monier publishes a weight of 49.5 kg per square metre for its Elabana concrete tile (about 11 tiles a square metre) and 47.25 kg for its Marseille terracotta tile. Steel sheets are much lighter, which is one reason people switch: the roof frame carries far less.

The flip side is wind. A light metal roof stays on through its screws, battens and the tie-down that connects the roof frame to the walls. When tiles come off, ask the roofer whether the battens and tie-downs will be checked and upgraded, and whether the job needs an engineer or a building certifier. Going the other way, from metal to tiles, puts far more weight on a frame that may not have been designed for it; our advice is to have an engineer check the frame first.

Approval rules for roof work are in the roof replacement approval guide, and the conversion itself is on the tile to Colorbond page.

Roof pitch: where tiles can and can’t go

Lysaght lists the “Minimum roof slope” for Custom Orb corrugated steel as 5°. For tiles, Monier says “The minimum pitch for a roof tile varies depending on the profile”; for Elabana it’s “Min with sarking 15°. Min without sarking 20°”. The building code’s own tile provisions apply to roofs pitched between 15 and 35 degrees.

So a low skillion or a flat-pitched extension that suits Colorbond may be too flat for tiles, while a tiled roof can always be changed to metal on pitch alone.

Heat: roof colour matters as much as material

How much of the sun a roof absorbs depends mostly on its colour. For new homes in Brisbane built to the code’s elemental provisions, the ABCB Housing Provisions say “the solar absorptance of the upper surface of a roof must not be more than 0.64”, and a darker roof means more ceiling insulation (see the sarking and insulation guide).

BlueScope says 21 of the core Colorbond colours and the Matt range “feature special Thermatech® solar reflectance technology”, designed “to reflect more of the sun’s heat on hot sunny days”, with results depending on “roof colour, roof shape, level and location of insulation” and the building. Monier publishes a solar absorptance for each of its tile colours, and points to tiles’ “excellent thermal mass, meaning they absorb heat during the day and release it gradually at night.”

Solar absorptance of popular Colorbond roof colours

colorbond.com colour pages, checked 23 October 2026. BlueScope says the values are “nominal values based on new product” (thermal values published 23 August 2022). Lower is cooler. For a tile colour, check the figure on the tile maker’s product page.

Rain noise on Colorbond and tile roofs

Steel can be louder than tiles in heavy rain; how much depends on what’s underneath. Lysaght says that “To reduce rain noise on metal roofing, an insulation blanket can be placed over the foil laminate”, pulled tight “to hold the blanket hard against the underside of the roofing to dampen the rain-induced vibration”, and that “If the blanket is not hard against the roofing the noise reduction will not be as good.” Monier, for its part, says “the natural density of tiles significantly reduces external sound”.

Ceiling insulation helps on both. If rain noise is a concern, ask the roofer which blanket and thickness they’re quoting.

Upkeep, repairs and hail

Tile roofs

Monier lists the usual causes of a leaking tile roof as blocked gutters and valleys, “Cracked or broken cement mortar bedding to the ridge or hip capping”, cracked or broken tiles and displaced tiles. It says “respraying your roof is aesthetic only and will not repair your roof”, that the colour coating on concrete tiles “is purely decorative”, and that terracotta tiles “do not fade as the colour is baked into the tile.” After storm damage, broken tiles can be replaced one at a time.

Colorbond roofs

BlueScope says Colorbond “requires minimal maintenance”: areas rain doesn’t wash, like the underside of eave gutters, “should be hosed down at least every six months”. On hail, it says dents “do not typically affect the lifespan” of a Colorbond roof, though deep dents on low-pitched roofs can hold water. The Colorbond lifespan guide has the detail.

Tiles or Colorbond on a character house

Many inner-north houses sit in Brisbane City Plan’s Traditional building character overlay. For work the overlay code assesses, the test is that “Development uses roof materials similar to the roof materials on dwelling houses constructed in 1946 or earlier nearby in the street.” Council’s Traditional Housing design guide notes that on traditional timber houses “Roofs were typically corrugated iron”, and that “Other styles include masonry with brick detailing and tile roofs.”

Our reading: on a pre-1947 timber Queenslander, new corrugated Colorbond in place of old iron is the like-for-like choice. Swapping original terracotta for metal, or iron for tiles, on a character house is the case to check with Brisbane City Council (07 3403 8888) before you get quotes. The re-roofing a Queenslander guide covers the overlay rules.

Cost to restore the tiles, re-tile or switch to Colorbond in Brisbane

On the published figures, a restoration that keeps sound tiles costs the least of the three. Re-tiling and switching to Colorbond both replace the roof covering and are priced per square metre, plus extras such as scaffold, insulation and certification.

Tile restoration, re-tiling and tile to metal prices in Brisbane

Checked 23 October 2026. Yakka Labour is a labour-hire company’s national cost guide (published 1 October 2026); its Brisbane row includes GST. whatsthedamage.com.au is a national cost-guide website that sells listings to roofers; its Brisbane rows (updated October 2026) include GST, and it doesn’t price tile-to-Colorbond conversions as a separate line. Fortified Roofing Group is a northside Brisbane contractor (Geebung); its post (updated 18 November 2025) doesn’t say whether GST is included. We found no Brisbane roofing contractor’s published price for re-tiling.

More tile-to-metal prices, including an all-in figure for a 180 m² house, are on the tile to Colorbond page; more restoration prices are in the roof restoration cost guide.
