Getting three quotes for a roof replacement is standard advice, but it only works if the three quotes are actually comparing the same thing. In the roofing industry, two quotes for the same property can look very different depending on what each contractor has included, the quality of materials specified, and how they have interpreted the scope of work. Comparing a quote that includes removal, disposal, gutters, and full flashing against one that only covers new sheeting is not a fair comparison, and the cheaper quote can end up being far more expensive once extras are added.
This checklist is designed to help Brisbane homeowners compare roof replacement quotes properly so they can make an informed decision. Fortified Roofing Group has built its reputation on transparent, itemised quoting and can walk you through any questions that arise during the process.
What Should Every Roof Replacement Quote Include?
Before you start comparing prices, check that every quote covers each of the following items. If any are missing, ask the contractor to clarify whether they are included or excluded.
Is the Removal and Disposal of Your Old Roof Included?
Removing the existing roof and disposing of the old materials is a significant part of any replacement job. Some quotes include this cost, others do not. Disposal costs can vary considerably depending on the volume of material and whether there is any asbestos involved. Always confirm that removal and disposal are explicitly included in the price, and if asbestos is present, verify that the contractor holds a valid asbestos removal licence.
What Roofing Material Is Being Quoted?
The type, profile, thickness, and finish of the roofing material all affect the quote. For metal roofing, make sure the quote specifies whether the material is:
- Colorbond: Specify the colour, profile, and BMT (base metal thickness)
- Zincalume: Confirm the profile and gauge
Cheaper quotes may use thinner gauge materials or unbranded alternatives that do not carry the same warranty. Always ask for the product specification by name so you can verify it independently.
Are Flashings, Ridge Capping, and Barge Capping Included?
Flashings seal the joints around chimneys, skylights, walls, and roof penetrations. Ridge and barge capping cover the peaks and edges of the roof. These items are essential parts of a weatherproof roof and should be listed in every quote. If they are not mentioned, ask directly whether they are included or will be invoiced separately.
Does the Quote Cover All Timber Repairs?
When the old roof is removed, the contractor will inspect the battens, rafters, and roof decking underneath. If damaged or rotted timber is found, it will need to be replaced before the new roof can be installed. Quotes often include an allowance for minor timber work but may not cover extensive structural repairs. Ask each contractor how they handle unexpected timber damage when it is discovered on site.
What Are the Payment Terms and Staging?
Reputable contractors typically request a deposit upon acceptance, with the balance due on completion. Be wary of contractors who ask for large upfront payments before any work begins. Confirm the payment stages and what triggers each payment in writing before signing.
What Contractor Credentials Should You Verify Before Accepting a Quote?
Price is only one factor. The contractor behind the quote matters just as much. Here is what to check:
- QBCC licence: All roofing contractors working in Queensland are required to hold a valid Queensland Building and Construction Commission licence. You can verify this on the QBCC public register using the contractor’s licence number. Fortified’s QBCC licence number is 15316575.
- Public liability insurance: Confirm the contractor holds public liability insurance of at least $10 million for residential work.
- Home warranty insurance: For jobs over $3,300, Queensland law requires contractors to provide home warranty insurance. Ask for evidence before work begins.
- References and project photos: Ask for references from recent similar jobs and check their portfolio of completed work.
What Additional Items Should You Ask About When Comparing Quotes?
Beyond the basics, here are additional scope items that may or may not be included in each quote:
- Roof insulation: Is sarking or blanket insulation included? What is the R-value?
- Roof ventilators: Is ventilation part of the scope, and if so, how many units and what type?
- Gutter replacement: Are gutters and downpipes part of the job?
- Downpipe replacement: Are these included or a separate cost?
- Scaffolding and safety equipment: How is this managed and is it included in the price?
- Site clean-up: Is the site left clean and clear of debris on completion?
How Do You Spot a Quote That Is Too Good to Be True?
A quote that is significantly cheaper than all others should raise questions rather than excitement. Ask yourself:
- Is the scope of work the same? Check line by line.
- Is the material specification the same quality and thickness?
- Does the contractor hold all required licences and insurance?
- Are there hidden provisional costs that could blow out the final price?
- Have you been able to verify their references and see recent completed work?
Cheap quotes can reflect genuine efficiency, but they can also reflect shortcuts in materials, under-insured workers, or an incomplete scope that will cost you more to complete later. The lowest price is rarely the best value.
