Start with a range—not a promise
The published Roofing Goats guide currently lists tile-to-Colorbond conversions at $18,000–$28,000 for a 100–180 m² roof, $28,000–$42,000 for 180–300 m², $42,000–$60,000 for 300–450 m², and $60,000–$100,000+ for extra-large or complex roofs. These are indicative Sydney guide ranges, not a quote or a guaranteed price.
Roof area is only one part of the job. The number and shape of hips, valleys and roof levels, access, the existing substrate, chosen profile, and the work revealed when tiles come off all affect the final scope. Roof area should be measured rather than inferred from the home's floor plan.
| Approx. roof area | Published indicative range |
|---|---|
| 100–180 m² | $18,000–$28,000 |
| 180–300 m² | $28,000–$42,000 |
| 300–450 m² | $42,000–$60,000 |
| Extra-large / complex | $60,000–$100,000+ |

What should be clear in a tile-to-metal quote?
A useful quote describes the work, not just a total. Ask the contractor to identify the roof covering and profile, the tile strip and disposal approach, underlay or insulation proposal, battens and timber inspection, flashings, gutters, access equipment, and how concealed damage will be handled. Get each relevant item stated as included, excluded, or provisional.
- Strip and disposal
- Confirm tile removal, loading, cartage and disposal are covered, and ask how unexpected hazardous material is handled.
- New roof system
- Name the steel/product, profile, finish, fixings and any manufacturer requirements. Confirm the design suits the measured roof pitch.
- Underlay and insulation
- Identify the proposed sarking or blanket by product/type and where it will be installed; don't rely on a vague 'insulation included' line.
- Flashings and drainage
- List valleys, ridges, wall and penetration flashings, gutters and downpipes separately so old components are not assumed to be replaced.
- Access and safety
- State scaffold or edge-protection arrangements and whether they are included in the quoted amount.
- Timber and unknowns
- Explain what is inspected after stripping, unit rates or provisional allowances, approval process and evidence before extra work proceeds.
Why the final figure may move
- Asbestos or other suspect material: stop and arrange appropriate identification and licensed handling where required. Do not assume ordinary tile disposal covers it.
- Scaffolding and access: height, roof shape, boundaries and site access affect the equipment and time required.
- Solar panels: removal and reinstatement may require a specialist and coordination. Ask who is responsible and whether electrical work is separately allowed for.
- Box gutters: condition, access, falls, outlets and associated building details can make replacement or repair a separate substantial scope item.
- Hidden deterioration: battens, rafters, fixings and substrate may only be fully assessed when the old roof is removed.
- Roof geometry and details: steep pitches, multiple junctions, skylights, chimneys and custom flashings increase material and installation effort.
Real roof conversions (project details, no price claims)
These completed case studies show why a single price band cannot describe every tile conversion. We have not attached prices: a suburb or a photograph is not evidence of a comparable quote, and the project scope differs from house to house.
Croydon Park · Inner West
Decramastic tile to Colorbond, including asbestos-positive coating
Testing identified asbestos in the tile coating. A licensed specialist handled removal, followed by full re-battening, new Colorbond, custom flashings and new gutters.

Kliplok roof replacement below a retained balcony
A storm-damaged, under-pitched roof with a difficult balcony junction was replaced using a tailored support and flashing approach. This is a metal-roof case study, not a tile conversion; it illustrates why access and junction details affect scope.

Under-pitched Kliplok replacement with wall flashings
An under-pitched custom roof and poorly sealed wall junction were addressed with a new Kliplok roof and pressure-flashed junctions. This is a separate metal-roof example, not a tile conversion.
View the projectGet an exact price for your roof
An accurate quote starts with an on-site inspection and roof measurement. Ask for the written scope, product selections, allowances and payment terms before work is agreed. The guide ranges above are a budgeting starting point only.
Can you give me a reliable price per square metre?
A single per-square-metre rate can mislead because it may omit tile disposal, scaffold, flashings, gutters, access or repairs. Use the published ranges only as a broad starting point and get a measured, itemised site quote.
Are the figures specific to tile-to-Colorbond work?
Yes. The ranges in this article are the tile-to-Colorbond bands published in Roofing Goats' Sydney cost guide. They are not a quote for your property.
Do project links include their contract prices?
No. These are case studies of the work completed. No project-specific price is claimed here; exact pricing depends on the inspected scope.
