Start with the council, because that part is quickly settled. Owners here usually want two things settled before they spend: what the work covers, and whether anyone besides the council has a say about their lot. Under the Sunshine Coast Planning Scheme 2014, a roof restoration on an existing house is accepted development with no requirements applicable, unless the property is a local heritage place.
What that answer settles is the council's question, and only the council's. Part of Peregian Springs sits in Community Title Scheme 39713, and that scheme's body corporate runs an architectural approval process that an owner applies to.
Here is the honest limit of this page: the scheme's by-laws are not on the public record, and nobody writing this has read them. So you will not find a statement anywhere on this page about what that process does or does not cover. What can be said is that the process exists, that it belongs to the scheme rather than to the council, and that an owner in the scheme can obtain the document and ask. That is a real gap, and it is why this page ends in an instruction rather than a rule.
The question is worth a reader's time here because this is not a suburb of detached houses only. In Peregian Springs, 20.4% of occupied private dwellings are semi-detached, row, terrace or townhouse dwellings, against 11.7% across Queensland, while separate houses are 78.1% against 74.8%. The scheme is not the suburb, though. Most occupied dwellings here are separate houses, and no source places any particular one of them in a scheme.
So the order in which you settle things matters. Establish first whether your own lot sits in a community titles scheme, and if it does, what that scheme's approval process asks of an owner. The scheme answers that, not this page and not a roofer. If a second body does have to be asked what work is proposed, the itemised written quote is the document that answers it.
