Getting a roof replacement quote is a crucial step before starting a replacement project. But a quote isn’t just a single price, a valid quote should include a number of critical pieces of information so you can properly assess a roofing contractor’s services. This guide shows you what to look out for and how to spot problem quotes. (If you want to estimate the price itself first, use our roof cost calculator.
What every roof replacement quote should include
There are several key areas that every quote should cover. Before any quote is given, a reputable roofer should conduct a site inspection to measure the roof size, assess the pitch and identify any existing damage, so the figures are based on accurate measurements rather than guesswork. Here’s what valid quotes typically include.

Legal and compliance
A professional roofing contractor should list their QBCC licence number on the quote. This shows they’ve met the necessary standards, like appropriate experience and the minimum financial requirements. They’ll also need to take out home warranty insurance if the job exceeds $3,300 in value.
In Queensland, replacing more than 20% of your existing roof area generally requires building approval from a licensed building certifier, so check the quote shows who is responsible for obtaining it. Compliance with current Australian Standards for wind uplift is also essential when upgrading a roof, especially on older homes, as tie-downs and fixings may need to be brought up to current standards.

Scope of the project
The quote should list exactly what is being included in the price. This could include information such as:
Whether the roofing material will be changed.
If an asbestos roof needs to be removed.
Work that will be done on features like roof ventilation.
Whether the project will include gutter replacement.
If the roof insulation will be replaced.
Whether there’ll be waste removal for old roofing materials included.
If structural roof repairs are needed on the existing roof first.
If your existing roof needs to be removed before the process, there will be additional costs for the removal and disposal of the old materials, which can vary based on the complexity and the amount of waste. Asbestos roofing is a special case: it requires specialised licensed removal, which will significantly increase disposal fees and labour costs, so confirm the quote accounts for it. Adding or upgrading insulation during the process can also increase the overall cost, but proper insulation supports energy efficiency and a comfortable indoor environment, with long-term benefits in energy savings.
The roofing material to be used
Your quote should clearly state which roofing material will be used, since the material is one of the biggest factors in the overall price and is generally accurate cost estimate per square metre. Options range from concrete roof tiles and terracotta tiles to metal roofing, slate roofing and asphalt.

Contract terms
The professional roofing contractor ensures to give you a schedule for providing the new roof. This means clarifying when the project begins and when it may be finished. It may also explain the process if the work done contains defects. Look to see what payment schedule the contractor accepts and how much they require upfront.
Warranties for both materials and workmanship should also be considered when comparing roofing options and contractors, so check what each quote covers and for how long.
How the costs should be presented
The costs should be broken down in an itemised list, separating labour from materials, with any adjustments clearly noted, for example, for complex roof shapes or a steep roof pitch that adds access and safety requirements. What you’re checking here is that the quote is transparent, not just a single bottom-line number.
Contact multiple roofing contractors for a quote. Comparing itemised quotes side by side helps you identify outliers and confirm that all costs have been accounted for.
Red flags and questions to ask before signing
One of the biggest red flags is being pressured to agree to a quote on the same day. This can be a sign that they’re not confident in providing quality workmanship. When you’re getting an expensive roof removal, you shouldn’t rush.
The Queensland Building and Construction Commission (QBCC) restricts how much a roofer may ask for as a deposit. The maximum deposit you should expect to pay is the following:
Jobs valued at $3,301 to $19,999 (Level 1): no more than 10%.
Jobs valued at more than $20,000 (Level 2): no more than 5%.
Level 1 or 2 jobs whose off-site work is more than 50% of the price: no more than 20%.
If you’re asked to pay more up front, query it with the contractor. You can refuse to pay a deposit that’s higher than the QBCC’s thresholds. For more on choosing a trustworthy contractor, see how to choose a reliable roofer in Brisbane.
