In Taigum the roof is the second question.
The first is procedural, and the dwelling mix sets it: 51.3% of dwellings here are semi-detached, row or terrace houses or townhouses, against 45.9% separate houses, with flats and apartments at only 2.1%. Low-rise and attached, in other words — roofs a restoration crew can realistically stand on, over homes whose owners may not be the ones entitled to commission the work.
The law behind that is short. A body corporate must keep common property in good and structurally sound condition and a lot owner must keep their lot in good condition, and which of the two holds the roof depends on the plan the scheme is registered under rather than on what the building looks like. Building format plan: the body corporate maintains the roof of the building, so the request goes to the committee. Standard format plan: the roof inside your lot boundary is yours to organise and yours to pay for. Two Taigum townhouses that look identical from the street can land on opposite sides of that line.
What the distinction means here is mostly about who is in the room. Taigum's median age is 40 and its 7,801 people occupy 3,262 private dwellings, of which 32.9% are rented and 29.9% are owned with a mortgage. So the person deciding is often an investor, a property manager or a committee — somebody who will never stand on the roof and reads a scope rather than seeing one, so the document has to survive being forwarded. A written quote therefore does more work in Taigum than it would in a street of freestanding houses: it is the thing a committee votes on and an absent owner reads.
Age sets the timing. The suburb name was formally recognised in August 1975 and its housing largely postdates the mid-1970s, so an original covering here has been in service for decades, and on tile that tends to show along the mortar long before it shows in the tiles. A reason to look, not a verdict.
None of this tells us how any particular Taigum scheme is organised. Nothing published sets out which plans its complexes use, how their roofs are laid out or who signs off, and we will not guess at it — the answer is in your registered survey plan and community management statement, which a body corporate manager or committee secretary can usually produce. On the 45.9% of Taigum dwellings that are separate houses, none of it applies and the inspection is simply the first step.
