Decide from the findings and the scope
Start with a written assessment of the roof covering, supporting structure and the cause of any leak. Compare the work that each proposal would retain, repair or replace. Age, appearance and price alone cannot confirm which approach is suitable.
Assess
Ask what is damaged, why it failed and what can remain.
Compare
Check repairs, preparation, materials and exclusions.
Document
Keep the findings, terms and completion records.
Start with an assessment of the problem
Ask for a written assessment explaining the condition of the roof covering, fixings, flashings and accessible supporting structure, together with the likely cause of any leak. Request photos taken safely by the assessor and note any areas they could not inspect. Structural concerns may need a separate assessment.
YourHome's maintenance guidance recommends expert advice for problems such as leaks and distinguishes maintenance from hazardous-material work. Roof age is useful background for that assessment, rather than a rule that decides the job.
A faded finish, a ceiling stain or a visible defect is a reason to investigate. Ask what evidence supports the proposed work, what remains serviceable and whether a targeted repair is an option. If proposals differ substantially, compare their findings before their totals.
Compare the work each option would involve
These are scopes to discuss with the assessor and contractor. They are not diagnoses or fixed packages.
| Option | Scope to ask about | Evidence needed |
|---|---|---|
| Targeted repair | Address the identified defect, such as a damaged component or a leaking detail. | What caused the problem, how the proposed repair addresses it and what further investigation is excluded. |
| Restoration | Retain suitable existing roofing, complete specified repairs and preparation, and apply a compatible finish where appropriate. | The condition of the retained roof and confirmation that the proposed treatment suits its material, existing coating and exposure. |
| Replacement | Remove and replace the agreed sections or roof covering, with associated work listed separately. | Which components need replacing, why repair or restoration is unsuitable, and whether supporting structure or other building work is also required. |
Replacing the covering does not automatically include new framing, gutters, insulation or every flashing. A restoration label does not establish that all defects will be repaired. Check the actual drawings, inclusions and exclusions.
Ask every contractor to price a clear scope
Use the same assessment and requested scope when seeking proposals. Keep alternatives separate so you can see what each price buys.
| Quote item | What to put in writing |
|---|---|
| Retained and replaced work | Roof areas, materials, repairs, preparation and finishes, with product names and specifications. |
| Related building work | Fixings, flashings, valleys, underlay, gutters, insulation and any structural work, each marked included or excluded. |
| Access and site arrangements | Access equipment, protection, waste handling, hazardous-material assessment and any approvals or inspections. |
| Unexpected findings | What cannot be assessed until work starts, any allowances and how additional work and price changes need to be authorised. |
| Handover | Completion records, care instructions, product and workmanship warranties, and the contact for defects or follow-up. |
For context on published examples and inclusions, use the roof restoration cost guide. Its examples do not price your roof or establish that one approach is always cheaper.
Agree the sequence and conditions for the work
Ask the contractor to explain assessment, approvals where needed, repairs, preparation, installation or coating, inspections and handover. Have them identify weather limits, access arrangements, product requirements and the plan for protecting exposed areas if work is interrupted.
Product instructions matter. The Dulux Acratex Metal Roof Renew page, for example, specifies suitable substrates, preparation and application conditions for that particular professional coating system. Its instructions are not a generic restoration process for every tiled or metal roof.
Get the proposed dates, assumptions and delay arrangements in the contract. A surface-drying or recoating time is not the duration of the whole project. This guide has no evidence establishing a standard restoration or replacement completion time.
Assess the outcome you need from the work
Compare how each proposal addresses the identified defects, what remains in place and what further care or work may be needed. Ask the assessor to explain any claimed remaining service life and the uncertainty behind it.
Appearance, intended use of the home and planned renovations can affect your priorities, but they do not resolve structural or water-entry problems. If selling, seek property-specific advice rather than assuming that replacement will recover its cost or should follow from a planned sale date.
Consider retained materials and planned upgrades
YourHome's renovation guidance recommends retaining and reusing feasible parts of a home and considering energy performance when planning work. Ask what can safely remain, what waste will be produced and how it will be handled.
If the work creates an opportunity to review insulation, ventilation or solar installation, get advice for the actual roof and building. Adding equipment does not by itself establish a need for replacement. Nor does a coating or a new roof establish a particular energy saving or environmental payback.
Check warranties and insurance separately
Get the cover for your actual roof
Ask who provides each warranty, which product or workmanship it covers, its exclusions, care requirements and claim process. Keep the written terms with the quote and completion records. A coating warranty is not a statement of the remaining life of the roof.
Specific exclusions matter: Dulux's Metal Roof Renew product page says that previously painted roofs may be recoated but are excluded from the warranty described there. Have the applicator confirm the terms for the proposed system and your existing surface.
The ACCC explains that voluntary warranties are additional to consumer guarantees. A stated warranty expiry does not remove those rights.
Ask the insurer about the policy
Moneysmart recommends checking policy cover, exclusions and limits, including the product disclosure statement. Ask your insurer about proposed work and any existing damage. Do not budget for a premium reduction or assume a claim will be accepted because the roof is new or restored.
Confirm approvals, credentials and safe assessment
Check approval requirements for the property's location, scope and constraints with the council or relevant building professional. As one state-specific starting point, the NSW Planning Portal explains that exempt minor works must meet all applicable standards and exclusions. This does not establish that a particular roof project is exempt.
Check the contractor's credentials for the proposed work in your jurisdiction. The NSW contractor-check guidance explains checking licence categories, status and conditions. An ABN check by The Wombat does not establish a trade licence, insurance cover or the suitability of a roof proposal.
Safe Work Australia identifies roof-access, fragile-roof, electrical and height hazards. Arrange professional assessment rather than climbing onto the roof or entering a roof space to follow this guide. If materials may contain asbestos, stop work that could disturb them and get appropriate advice. Asbestos NSW warns against sanding, scrubbing, water-blasting, cutting or drilling suspected asbestos.
