What changes the price
- What is inside the quote. Battens, sarking blanket, tie-downs, flashings and waste disposal are the usual gaps between a cheap quote and a dear one. Ask for each as a line.
- Material change. Swapping tiles for Colorbond can need tie-downs, a permit or engineering. Ask who arranges it and who pays.
- Roof size and shape. Price follows roof area. A highset or a roof with many valleys costs more per square metre than a simple gable.
- Insulation, gutters and downpipes. Some quotes bundle them and some do not. One Brisbane homeowner's $18,000 plus GST quote for a 90 m² highset covered the roof, insulation, gutters and four downpipes (r/AusRenovation, October 2024).
- Compliance certificate. Insurers can refuse a claim on a roof that was not installed properly. Ask for the certificate at handover.
- Access door and extras. Ask for an access door to the rest of the roof, and for waste disposal in the contract.
- Warranty. Years, cover and who backs it, in writing.
Ask every roofer to price the same list, in writing, so you are comparing like with like.
Questions to ask before accepting a quote
How much does a roof replacement cost in Australia?
Published cost guides disagree on a roof replacement: $14,000 to $40,000 per job in one, $18,000 to $45,000 per job in another (published cost guides, checked 17 Oct 2026). Small roofs sit at the low end; highset and complex roofs sit at the high end.
Why do roof replacement quotes differ by tens of thousands?
Because the inclusions differ. One homeowner reported five quotes for the same 205 m² Colorbond roof from $29,800 to $47,200 (r/AusRenovation, April 2025). Ask each roofer to price battens, blanket, tie-downs, flashings and disposal as separate lines.
Do I need approval to swap tiles for Colorbond?
You may. Ask your council and insurer first, and ask the roofer for the compliance certificate afterwards. Do not rely on the roofer's word alone.
How much deposit is normal for a new roof?
Get the amount and the payment stages in writing before you sign.
Do I need a licensed roofer in your state?
Ask for the number and look it up on your state register. The guide to hiring a roofer links to each one.
What should the contract include?
