Before ordering a replacement roof, settle who will check the consent position. “It is only a re-roof” is not a complete answer. The scope and the condition of the existing building matter, and a general article cannot decide the status of a particular property.

Describe what is actually changing
List the existing cladding, the proposed replacement and any work beyond the surface material. Include changes to the roof shape, supporting structure, penetrations or other parts of the building. Give your adviser photographs and any available plans, but do not expect photographs to answer every structural question.
If the current roof has failed, explain what is known about the failure rather than describing it simply as old. Keep inspection findings separate from assumptions.
Ask which exemption, if any, applies
MBIE's general repair, maintenance and replacement guidance includes examples of roof cladding replacement. It also sets conditions and exclusions. An example is not blanket permission for every roof described as like-for-like.
Ask your council or appropriate building professional to consider your actual scope. Exempt work still needs to comply with the Building Code. Keep a record of the advice and the scope on which it was based; changing that scope may change the answer.
Put responsibility and timing in the programme
Agree who obtains further advice, prepares any required documents and allows for approvals before work starts. Ask what remains unresolved before paying for an order that assumes the approval question is settled.
