Cost to replace a tile roof with Colorbond in Brisbane

Published 5 November 2026

Tile to Colorbond roof cost per m² and per house

Most Brisbane price guides give a rate per square metre of roof. Roof area is larger than the floor area, because of the eaves and the pitch, so ask the roofer for the roof area they’ve measured.

Tile to Colorbond prices in Brisbane

Checked 5 November 2026. Fortified Roofing Group is a northside Brisbane contractor (Geebung); its tile-to-metal post was updated 18 November 2025 and doesn’t say whether GST is included. Yakka Labour is a labour-hire company’s national cost guide (published 1 October 2026); its figures “include GST”, and the last row is from its national table, not its Brisbane row.

By our arithmetic, Yakka Labour’s Brisbane rate on a 180 m² roof comes to $18,000 to $28,800 (180 × $100; 180 × $160), before any extras that aren’t in its rate.

What a tile to Colorbond price should include

Fortified’s base rate covers stripping the tiles and timber battens, new metal battens and the new roofing, and leaves out insulation, engineering approvals and scaffolding; its all-in figure adds them back. Quotes differ most on what’s left out, so ask for each of these as its own line:

• Tile and batten removal, the skip and disposal
• New metal battens and how they’re fixed to the rafters or trusses
• Sarking or an insulation blanket under the sheets
• Colorbond sheets, ridge capping, flashings and valleys
• Tie-down checks and any upgrade work, with engineering or certifier fees if needed
• Scaffold or edge protection, new gutters, and lifting off and refitting solar panels

Published prices for scaffold, gutters, battens and solar remove-and-refit are in the roof replacement cost guide.

Tie-down when you replace tiles with Colorbond

A tile roof is heavy enough that its weight helps hold it down; a steel roof is roughly a tenth of the weight (the figures are in the Colorbond vs tile guide). That changes what holds the roof on in a storm. Timber Queensland’s technical sheet on wind tie-down, published by the QBCC, says “Even at low wind speed classifications such as non-cyclonic N2, sheet roofed houses will have net wind uplift forces that need to be tied-down with specific tie-down connections.” It adds that “failure of one link in the tiedown chain can lead to loss of a whole roof in a wind event”, and that the connection of battens to rafters and trusses needs “Special attention” at “high local pressure areas such as hips”.

The Australian Government’s resilience library lists “replacing tile roofs with sheet roofs” as a topic for builders, and says “the tie-down must be appropriate for the wind classification”. Each house’s wind classification is set for its own site, so ask the roofer or certifier what it is for yours.

• Ask how the battens will be fixed to the rafters or trusses, and how the rafters are tied to the walls.
• Ask what happens if the frame’s connections aren’t up to the new roof, and how that work is priced.
• Ask whether an engineer or a building certifier is involved, and who arranges them.

Engineering and certification fees on a tiled re-roof

From Fortified’s tiled roof replacement post for Brisbane and South East Queensland (updated 12 January 2026), checked 5 November 2026. GST not stated. Whether your job needs either depends on the roof and the certifier. No one in Brisbane publishes a price for the tie-down work itself.

No Brisbane roofer publishes a price for tie-down upgrades; it depends on what’s found once the tiles are off. When roof work needs building approval, and the questions to ask about older houses, are in the roof replacement approval guide.

Sarking and insulation blankets under the new sheets

The ABCB’s energy-efficiency rules count a tiled roof with no sarking as a “vented” roof. A steel roof doesn’t get that treatment, and moisture can condense on the cold underside of the sheets. Lysaght, the steel roofing maker, says “a vapour barrier is often used to prevent contact of warm moist air with the roofing”, and that foil laminate “must be draped between roof supports so that the cold cladding is not in contact with the laminate (except at the supports)”.

Which product to choose, and the R-values for Brisbane, are in the sarking and Anticon guide; its cost section has the published prices.

Asbestos on a tile-roofed house

The Queensland Government’s list of where asbestos cement was used on the outside of houses doesn’t include concrete or terracotta tiles, but it does name “roof sheeting and capping, guttering, gables, eaves/soffits, water pipes and flues”. On a house built before 1990, ask the roofer whether any flashings, capping, eaves lining or flue around the roof could be asbestos cement, and how they would handle it before work starts.

The asbestos roofs guide covers testing and the rules on cutting or drilling it.
