What we look for in Roleystone, and why it differs from the suburb next door. 29.3 km from the CBD, 30.0 km from the coast, postcode 6111.
Roleystone sits in the Darling Range about thirty kilometres from the city, on large lifestyle blocks among bushland and fruit orchards. Buckingham's sawmill operated here from 1865, and the area was subdivided into farmlets in 1902 for orchards and market gardens. The winding tree lined roads are part of why people come. They are also fuel.
These are properties rather than houses. Large blocks with long private drives, outbuildings, sheds, water supply arrangements and effluent systems, all of which form part of what you are buying and none of which is covered by looking at the dwelling.
The terrain is steep, winding and treed, with laterite and gravel over rock. That produces sloping sites, cut and fill platforms, retaining walls and stormwater that has to be managed all the way down and off the property. Retaining is where the money goes wrong up here, and replacing a failed wall on a steep block with poor access costs several times what the same wall would cost on flat ground.
Former orchard and market garden land brings old irrigation and, on some parcels, legacy chemical residues worth understanding.
Fire is the defining risk. The February 2011 fire that ran through here and Kelmscott destroyed 72 homes. For a Roleystone property that means BAL ratings, ember protection, defendable space, water supply available for firefighting, and whether a fire appliance can physically get up a steep private drive. Those are not formalities on a block like this.
Deep bushland means high termite pressure, permanently. There is no meaningful break between forest and housing on most blocks, and the surrounding habitat holds established colonies continuously.
Orchard history adds to it. Old fruit tree stumps left in the ground. Irrigation lines that leak long after anyone is watching. Fence and trellis posts set into soil across large areas. Sheds sitting directly on the ground rather than on footings.
Firewood stacked against a house is close to universal in the hills and it is a genuinely bad idea. Timber retaining on sloping blocks adds more contact points. On a steep site the subfloor or undercroft may be generous enough to inspect properly or nearly impossible to enter, and we say which we managed.
Getting an inspector this far into the hills takes time, and covering a large lifestyle block properly takes hours once outbuildings and services are included. Doing it twice is not sensible. One attendance also means one person assesses the slope, the drainage, the retaining and the timber against a single understanding of the site. Reported under AS 4349.1 and AS 4349.3.
Buyers here often want the water supply and effluent system looked at specifically, since both are private and both matter more than they would on a serviced suburban block.
Building on these blocks is difficult, so staged inspections while retaining and site works are open earn their keep. Neighbour disputes tend to involve retaining walls, access easements and stormwater running from one property onto another, and we prepare reports on those.
Roleystone sits on the laterite foothills of the Darling Scarp — lateritic gravel and clay over granite, with rock close to the surface and real slope. Slope is the defining feature. Cut and fill, split levels, and retaining walls are normal here rather than exceptional, and retaining is where the money goes wrong. Rock near the surface also means surface water runs rather than soaks.
What that means in practice, on a house in Roleystone:
Landform is assigned from the suburb's position on the Swan Coastal Plain rather than from a site soil test. It tells you what to expect, not what you have. A site classification to AS 2870 is a different exercise and a different report.
Araluen Botanic Park is the fixed point most people in Roleystone navigate by. Buildings like it are useful to an inspector for a duller reason: they date the area. Whatever era put that up is usually the era that put up the houses around it, and the construction methods of that decade are what we expect to find in the roof.
Martin, Pickering Brook, Bedfordale, Carmel and Bickley sit on the same ground as Roleystone, so the footing behaviour and the drainage problems tend to repeat across all of them. If you are comparing houses across those suburbs, you are largely comparing the same site conditions.
Kelmscott is 9.6 km away but sits on the Guildford Formation. That is the useful thing about this part of Perth: the ground can change inside a few kilometres, and with it what an inspection is looking for.
On site classification: any soil zone quoted for a suburb is indicative, inferred from geography rather than surveyed. A real AS 2870 classification comes from geotechnical work on your actual block and can differ from the one next door. We report what we observe; we do not read your soil class off a map.
The inspection is visual and non-invasive, over the readily accessible areas, reported to AS 4349.1. Our inspectors physically enter the roof space, as long as there is sufficient access. Report within 24 hours of the inspection.

Well inland at 30.0 km from the coast, out in Gosnells, Roleystone is far enough from the water that salt takes a back seat. The same fee goes into footings, drainage and the ground movement typical inland, and the tiled roof is checked for delignification only near heavy traffic.

Yes. Our inspectors physically enter and inspect the roof space, as long as there is sufficient access to do so safely. Where access is restricted, the report says so plainly rather than implying we saw more than we did.
At 30.0 km inland, Roleystone carries lower coastal-salt exposure, so delignification is not the first thing we would expect. It remains possible near heavy arterial corridors or industrial emissions.
Within 24 hours of the inspection itself, not 24 hours from booking. On a pre-purchase or pre-settlement job that timing is the whole point, because your leverage disappears once you are committed.
We would rather you checked than took our word for it. These are the bodies that actually hold the records and set the rules:
