Like-for-like re-roofing, routine repair and maintenance, and like-for-like spouting replacement are generally exempt from building consent under Schedule 1 of the Building Act. Consent is generally required for a change of roofing material class, structural roof alterations and any work on a heritage-listed building. Confirm with Auckland Council or a building certifier before you start.
| Roof work | Consent? |
|---|---|
| Like-for-like re-roofing (same material and profile) | Generally not required |
| Routine repair and maintenance (tiles, flashings, ridge capping, painting) | Generally exempt |
| Like-for-like spouting and gutter replacement | Exempt |
| Change of roofing material type, such as tile to metal | Generally required, though it can sometimes be resolved by a minor variation or specific exemption |
| Structural roof alterations (pitch, dormers, roof structure) | Required |
| Heritage-listed buildings | Specific consent is required for any roof work |
One of the most common questions Auckland homeowners ask when planning roofing work is: do I need a building consent? The answer depends on the type of work, whether it constitutes restricted building work, and whether material or structural changes are involved. Getting this wrong — proceeding without required consent — can create significant problems when selling your property.
When Is Building Consent NOT Required in Auckland?
Under the NZ Building Act's Schedule 1 exemptions, the following roofing work generally does not require a building consent:
- Like-for-like re-roofing: Replacing existing roofing with the same material and profile (e.g., replacing concrete tile with concrete tile, Colorsteel long-run with Colorsteel long-run).
- Routine repair and maintenance: Replacing individual tiles, repairing flashings, resealing ridge capping, painting — all maintenance work is generally exempt.
- Spouting and gutter replacement: Like-for-like spouting replacement is exempt from consent.
- Roof-mounted solar panels: Since October 2025 the Building (Exempt Roof-mounted Solar Panel Arrays and Building Work) Order 2025 exempts many roof-mounted arrays from building consent — up to 40 m² in wind zones up to High, and larger arrays or higher wind zones when a Chartered Professional Engineer designs or reviews the installation. The Order has conditions, so check MBIE's current guidance; the electrical connection is separate work. See our solar roof compatibility guide.
Note: Even where consent is not required, work that constitutes restricted building work (RBW) must still be carried out by or under the supervision of a Licensed Building Practitioner (LBP). My Homes Roofing Expert completes all roofing work categories in full compliance with New Zealand building regulations.
When Is Building Consent Required in Auckland?
Consent is generally required for:
- Change of roofing material type: Switching from one material class to another (e.g., concrete tile to metal) — although this requirement can sometimes be resolved via a minor variation or specific exemption. Our team advises on this case-by-case.
- Structural roof alterations: Changing roof pitch, adding dormers, altering roof structure — all require consent.
- Adding skylights: A new skylight creates a new roof penetration and can affect framing and weathertightness, so whether consent is needed depends on how it is installed — confirm with Auckland Council before ordering, and see our skylight installation guide.
- Heritage properties: Any roof work on a heritage-listed building in Auckland requires specific consent regardless of the nature of the work.

What Questions Do Auckland Homeowners Ask?
Do I need building consent to change from tile to metal roofing in Auckland?
Changing from concrete tile to Colorsteel metal may or may not require consent depending on specific circumstances. Auckland Council's building consent team can confirm this for your specific property — our team can also advise based on experience with similar projects.
What happens if I re-roof without required consent in Auckland?
Unpermitted work can create significant issues when selling your property — buyers' solicitors and bank valuers will identify it during due diligence. Retrospective consent (Certificate of Acceptance) applications are complex and costly. It's always better to determine consent requirements upfront. Safe roof access is also a legal requirement — read our guide on roof anchor points Auckland installation and compliance obligations.

What else should you know?
Do I need building consent to replace my roof in Auckland?
Like-for-like replacement with the same material and profile generally does not need consent, because it is exempt under Schedule 1 of the Building Act. Changing the roofing material class, altering the roof structure, or working on a heritage-listed building generally does. Confirm with Auckland Council or a building certifier before you start.
What is restricted building work on a roof?
Even where building consent is not required, work that counts as restricted building work must still be carried out by, or under the supervision of, a Licensed Building Practitioner. Ask any roofer how they will meet this requirement for your job before work begins, and check the practitioner on the public register.
Does routine roof maintenance need building consent?
No. Replacing individual tiles, repairing flashings, resealing ridge capping and painting are all routine maintenance and generally exempt, as is like-for-like spouting and gutter replacement. Work can typically proceed promptly after an on-site assessment, so there is no consent delay for these jobs, but heritage and structural work should still be checked first.
