Customers tend to itemise a restoration only after it is over - pressure cleaned, gutters cleaned, repointed, tiles replaced, painted and sealed - which is why a quote is hard to judge beforehand. The business publishes its own order of operations: inspect, clean, repair, coat or seal, final check. Read as a household rather than as a roof, that list separates the stages which barely register from the one that takes over the yard.
The cleaning stage is the one an occupied house notices. It turns a whole roof surface into spray and run-off above windows, a clothesline and whatever is on the ground below. It is also the stage a Queensland rule constrains: high-pressure water blasting of asbestos or asbestos-containing material is illegal, including outside workplaces, and Queensland Government guidance states that a house built before 1990 has a good chance of containing some asbestos and that you cannot tell by looking. That is not a statement about any house in this suburb. It says that on an older roof the material has to be identified before anything is blasted, which is why that question belongs at the inspection and not on the morning the cleaning starts.
The rest is logistics. Windows shut and washing off the line on the cleaning day; cars off the driveway; pets inside; outdoor furniture moved; an outside tap and a power point the crew can reach; and the neighbour over the fence, whose line sits under the same spray. Customer accounts of this business's past jobs single out those details - one describes a crew checking with neighbours about washing on their line before cleaning a shed roof, another a courtesy call fifteen minutes ahead of arrival. Timing, arrival and neighbour impact come up unprompted in that review corpus. Ask whoever quotes how each of those is handled, and have the answers written into the scope.
Two of those answers are not published anywhere. A start date and a number of days on site are evidenced only by one customer's account of one job, which mentioned a date being booked and the work running over two days - one job, not a stated practice. So they have to be asked for and written down: the start date, the number of days, and which day the cleaning falls on. The rest the business does publish: no charge for the visit, obligation-free, a written and emailed quote with an itemised price and a transparent breakdown of costs, fixed for the agreed scope.
