What we look for in Coogee, and why it differs from the suburb next door. 20.3 km from the CBD, on the coast, postcode 6166.
Coogee sits on Cockburn Sound with views out to Garden, Carnac and Rottnest Islands. It was limestone ridge with small rural lots and market gardens, and the older Coogee Beach locality holds nineteenth century buildings including the 1898 hotel. Most of the current residential is 1980s onward. Some is far older.
Genuine oceanfront exposure leads the inspection. Everything else follows. Delignification is a serious check on any tiled roof past a decade, because salt laden air works on battens and rafters continuously. Corrosion attacks fixings, flashings and external metalwork. The position is exposed, so wind and weather test roofs, eaves and flashings harder than they would inland.
Underneath is limestone ridge with slope running down toward the coast. Limestone near the surface affects how footings were formed, and on the oldest stock the footings may be limestone themselves. Coastal facing slope means drainage has to be managed down the block.
The suburb spans a wide range. Nineteenth century to last year. A few nineteenth century buildings around Coogee Beach, the bulk of the housing from the 1980s onward, and newer estate and marina density near Port Coogee where inspections become strata. Establish which you are dealing with first.
Woodman Point adjoins, with its WWII munitions jetty and stores history on the reserve.
Coastal limestone and sand keep general pressure lower here than inland, so the useful work is finding the specific exposures rather than treating the whole property as high risk.
Timber in ground contact is the main route, and on a coastal slope there is usually a lot of it. Retaining walls stepping down the block, decking, pergolas and fencing all degrade faster in salt air and get replaced in stages, so recent untreated timber is generally in the ground somewhere.
Limestone footings on the older stock weather into voids and cracks that give concealed paths to the timber above, so a footing that looks solid can be full of routes nobody can see. Reticulation on a sandy slope creates damp pockets that would not otherwise exist, usually where the ground flattens.
On a sloping coastal block the retaining matters to both inspections. One assessment is asking whether it is holding, the other what is living in and behind it, and that is the same wall. Reported under AS 4349.1 and AS 4349.3.
On a coastal slope, walk the lowest part of the block before buying. Water collects there, retaining fails there first, and neither is visible from the front of the house.
Near Port Coogee we do strata work on the marina density, where coastal concrete condition is the recurring question. On the older beach stock we assess additions for approval and prepare condition records where rebuilding happens on a neighbouring block.
On any older house here, get into the roof before you negotiate. On this stretch of coast the condition of the battens is the largest single unknown, and no amount of looking at the outside of the building will answer it for you.
Coogee sits on the Quindalup dune system — young calcareous sand, still mobile in places, and thin over the water table near the front. Sand this young has low bearing capacity but very little reactivity, so footing movement is uncommon and drainage problems are not. What the ground gives you here it takes back in the air.
What that means in practice, on a house in Coogee:
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.
Coogee Hotel is the fixed point most people in Coogee 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.
North Coogee, Spearwood, Lake Coogee, Hamilton Hill and Beeliar sit on the same ground as Coogee, 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.
Yangebup is 4.0 km away but sits on the Spearwood dune system. 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.

Right on the coast in Cockburn — the band where coastal salt drives the defects. The fee concentrates on delignified battens, corroded ties and fixings, and the salt staining that starts inside the masonry, with the roof space taking the longest on a tiled roof past its first decade.

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.
Coogee is on the coast, inside the band where delignification should be expected in tile battens. On a tiled roof more than about ten years old it is one of the first things we look at.
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:
