Take the first gate. At the 2021 Census, 38.5% of Mooloolaba's occupied private dwellings were separate houses, 11.6% were semi-detached, row, terrace or townhouses, and 47.6% were flats or apartments, against 74.8%, 11.7% and 12.5% across Queensland. The townhouse share is the ordinary part of that picture, level with the state figure. The distortion is entirely in flats, close to four times the Queensland share, and in houses, at roughly half of it. Restoration as described here addresses the smaller share - dwelling structure as the ABS measures it, not a statement about anyone's title.
If your dwelling is a flat or a unit in a complex, the business publishes multi-unit capability for roof cleaning only: its cleaning pages state coordination with body corporates for townhouse complexes, multi-unit complexes, and high-reach safety gear. No equivalent statement appears for restoration, re-pointing or painting on a multi-unit building, so the roof cleaning page for Mooloolaba is the page for that reader. Roof replacement and re-roofing are not work this business performs; a roof past restoring is a matter for a licensed re-roofing contractor and a building certifier.
At the 2021 Census, 80.2% of Mooloolaba's 4,678 private dwellings were occupied on census night, against 90.7% across Queensland. That count is taken by place of enumeration, where the dwelling-structure and tenure figures are place of usual residence, so the two are not the same basis. The ABS records whether a dwelling was occupied that night; it does not record why one was not, and this page does not guess.
The second gate is measurable. The Code sets corrosion protection for metal sheet roofing in metres from breaking surf: within 100 m, metallic coatings are listed as not suitable, and from 100 m to 200 m a minimum of AZ200 or AM150 applies. Those thresholds fall inside one suburb, so it is your own address to measure, from the high-water mark; no authority publishes a band for a suburb. Part 7.2 governs metal sheet roofing; on a tile roof it reaches only fixings and flashings.
Fixings are how any of that reaches a tile roof at all. Lysaght, as manufacturer documentation, says plainly that its own fastener table is rough guidance based on distance from marine influences only. The distance is a reason to ask, not an answer off a table.
