There is no one-size-fits-all approval answer
Some maintenance or replacement work may qualify as exempt development when every relevant standard and condition is met. A change from tiles to metal can alter appearance, materials and details, so do not assume it is exempt simply because the roof footprint stays the same.
The planning pathway depends on the precise work, the property's planning controls and constraints, and whether all applicable exempt or complying development standards can be met. If those tests are not satisfied, another approval pathway may be needed. This is general information, not legal or planning advice.
Check heritage and local controls early
A heritage item, conservation area or other local planning control may affect whether a change in roof material, colour, profile or appearance is acceptable. Paddington is a real example: parts of the suburb fall within heritage conservation areas covered by Woollahra or City of Sydney controls. Inner West Council also maps its heritage conservation areas, but warns that older HCA numbers are being updated under its current planning controls; we cannot verify the brief's '102 areas' figure as a current official count. Check the specific property and current Local Environmental Plan, Development Control Plan and heritage guidance.
Search the NSW Planning Portal Spatial Viewer by address, then confirm the mapping and rules with the relevant council or a qualified planning professional. A map result is a starting point, not a decision that development consent is or is not required.
- Check whether the property is a listed heritage item or lies in a heritage conservation area.
- Review the current council planning controls and any relevant roof/streetscape guidance.
- If controls are unclear, ask council in writing or get planning advice before choosing a material or colour.
Bushfire-prone land changes the technical checks
If a property is mapped as bushfire-prone, the applicable bushfire planning and construction requirements may affect the roof assembly and associated details. A metal covering by itself does not establish that the complete building complies. Confirm the mapped status, applicable BAL assessment and relevant construction requirements with the appropriate council, certifier or building professional.
How to check the property
- 1
Search the NSW Planning Portal
Use the Spatial Viewer to search the exact address and inspect the displayed planning layers, including heritage and bushfire mapping where available.
- 2
Read the pathway rules
Review the current NSW Planning Portal pages for exempt and complying development. Check every relevant condition; a roof replacement may not meet all of them.
- 3
Ask the consent authority
Contact the local council or a qualified planner/certifier with the exact scope, roof material/profile, colour and any structural or drainage changes.
- 4
Keep a record
Save the mapping result, advice and any approval or certificate documents with the building contract.

What Roofing Goats can help with
We can explain the proposed roofing work, identify the material/profile options and provide a written scope for you to use when checking the approval pathway. The property owner remains responsible for confirming approvals, and we do not promise that a specific roof conversion is exempt. If a consent or certificate is needed, agree who will obtain it before work is scheduled.
Is every like-for-like re-roof exempt in NSW?
No blanket answer applies to every property and scope. Exempt development has conditions, and property controls may affect the pathway. Check the current official rules and address-specific constraints before proceeding.
Does the Planning Portal map decide whether I need approval?
It helps identify planning information and constraints. It does not replace checking all applicable standards or getting advice from the consent authority, certifier or planning professional.
Can the roofing contractor confirm my conversion is exempt?
A roofer can describe the work and provide scope details, but an approval pathway should be confirmed against current controls by the appropriate authority or qualified planning professional.
