Some surfaces should never see a pressure washer at all and asbestos cement is top of that list. On Ardross properties we identify what we are cleaning before the trigger gets pulled and we will decline work that would cause damage.
Why Ardross roofs behave the way they do
Ardross sits with Applecross and Mount Pleasant on the peninsula that juts into the Swan River. That riverside position brings salt back into an inspection after the inland Melville suburbs: delignification is a genuine check on the older tiled roofs here. The peninsula is also elevated, prized for its river vistas, so many blocks are sloping view sites, with retaining walls, cut-and-fill and down-slope drainage to assess. River-peninsula land value drives knock-down-rebuild, so Ardross's interwar and mid-century homes now sit beside large modern prestige builds, two different inspections. On the new ones it is worth checking the build quality matches the price. The suburb's landmark is Wireless Hill, a 40-hectare bushland reserve on the site of WA's first radio station; blocks near it back onto genuine bushland, so a little termite pressure comes with the amenity. The Riseley Centre restaurant-and-retail strip is a busy activity node, so nearby blocks can see some higher-density housing (with strata inspections) and the usual traffic and noise. Not always. Between the river salt, the elevated sites, the old-versus-new split and the Wireless Hill bush edge, an Ardross report depends on which part of this varied peninsula suburb a property sits in.Pressure Cleaning in Ardross: the short version
The machine is the easy part. Judging pressure for a given surface, choosing the right nozzle and working at the correct distance is what separates a clean from damage. Detail sits on our pressure cleaning page.
What that means for pressure cleaning in Ardross
Paving near the beach greens up on the shaded side faster than inland equivalents because it stays damp longer and treating it beats repeatedly blasting it.
Aged tile in this part of Perth has been damp for decades, which softens the surface layer. High pressure strips it and leaves the roof more porous than before, which is a genuinely perverse outcome.
Old buildings need the lightest approach available. Soft limestone, lime mortar and original render are all softer than the water pressure most machines deliver and damage to them is permanent.
Sand is abrasive and gets everywhere on exposed blocks, so surfaces here carry a gritty deposit that responds well to volume rather than force.
Ardross roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Old render, powdery to touch | Substrate already failing | Do not pressure clean, assess first |
| Fibre cement sheeting, weathered | Possible asbestos content | Stop, identify before touching |
| Timber decking, greyed | Soft grain, raises easily | Low pressure with the grain |
| Limestone, historic | Soft and permeable | Specialist approach, not high pressure |

Roof Cleaning in Ardross
Learn moreRoof cleaning strips the moss, lichen and black weathering off a Ardross roof and gets it back to a clean, even surface — either as a standalone tidy-up or as the first stage of a restoration. We treat the growth first so it dies at the root, then clean at a pressure matched to the tile so we lift the grime without stripping the surface or driving water under the laps.
Left alone, that growth holds moisture against the tiles and works into the pointing, which is why we treat rather than just blast it — the same method we use through nearby Applecross. We check the roof over while we’re up there and flag anything that needs attention, so a clean doesn’t paper over a repair that’s quietly getting worse. On steeper or two-storey Ardross roofs we work off proper anchorage and stay off the tiles where we can, so the clean lifts the grime without cracking the very surface it’s meant to protect, and we’ll let you know if the roof would be better served by a full restoration.

02Roof Restoration in Ardross

Roof Restoration in Ardross
Learn moreA roof restoration renews a tired but sound Ardross roof for a fraction of replacement: we treat the moss and lichen, high-pressure clean, replace broken tiles, re-bed and re-point the ridge caps in a flexible compound, then seal and coat with a Dulux AcraTex membrane as accredited applicators.
It’s the right call when the tiles have decades left but the surface and pointing are gone — the same judgement we bring to nearby Mount Pleasant. We’ll tell you honestly whether a restoration suits your roof or whether repairs or a re-roof make more sense, and the finished job carries both a manufacturer coating warranty and our 10-year workmanship warranty. Most Ardross homes take two to three days depending on the repairs needed before coating. As accredited applicators we prepare to the manufacturer’s specification, so the membrane actually holds — a coating only lasts if the surface beneath it was treated, cleaned and repaired properly first, which is exactly where a cheap spray-over fails within a couple of summers.

Roof Repairs in Ardross
Learn moreMost Ardross roof problems come down to a handful of failures: cracked or slipped tiles, perished ridge pointing, rusted valley irons and tired flashings. We trace the leak to its actual source — which is rarely under the ceiling stain — and fix the cause, whether that’s replacing matching tiles, re-bedding and re-pointing the ridge in a flexible compound, or renewing a corroded valley.
We’ll always tell you honestly when a roof is genuinely repairable versus when the repairs are mounting up and a restoration would serve you better, as it often does through nearby Brentwood. Prompt repair matters: a single cracked tile left through a wet winter becomes soaked insulation, stained ceilings and, eventually, damaged roof timber. Every repair is backed by our workmanship warranty, and because we photograph what we find and talk you through it, you’ll understand exactly what was wrong and what we did about it rather than being handed a bill and a shrug.

Roof Replacement in Ardross
Learn moreWhen a Ardross roof reaches the end of its life — porous tiles, rusted-through valleys, or a roof that’s been patched one too many times — a full re-roof is often the honest answer. We strip the old covering, check and repair the timber and battens underneath, and install a new tile or Colorbond roof with fresh sarking, valleys and flashings throughout.
A tile-to-Colorbond conversion is popular here for its lighter weight, clean lines and colour range, and because the lighter roof changes the wind uplift we reassess the tie-down as part of every conversion. We’ll also be straight about whether you’ve genuinely reached replacement or whether a restoration, as we do through nearby Booragoon, would renew the roof for a fraction of the cost. Every re-roof is engineered and tied down to Australian Standards and backed by our 10-year workmanship warranty, and we handle the guttering, flashings and tie-down as one job so nothing is left for you to chase afterwards.

Roof Inspection in Ardross
Learn moreA roof inspection is the cheapest way to know exactly what your Ardross roof needs before you commit to anything — or before you buy. We get onto the roof and into the roof space, physically checking the tiles, pointing, valleys, flashings, gutters and the structural timber, then hand back a clear written report with photographs.
On older homes we test the timber for rot, termite damage and delignification; on newer ones we look for the builder-grade detailing faults that leak early. It’s the same thorough check we run through nearby Myaree, and it’s what tells you whether a roof needs a minor repair, a restoration or something structural. If you’re buying a home, an inspection of the one part most people skip — the roof space — is money very well spent, and the written report gives you something concrete to put in front of an agent, a buyer or your insurer rather than a verbal all-clear.

06Roof Carpentry in Ardross

Roof Carpentry in Ardross
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Ardross homes we repair and rebuild that framing to standard: sistering weakened members, replacing rotted or termite-damaged timber, and reinstating trusses that have been cut for a skylight, duct or downlight.
We also test for delignification, the chemical breakdown that leaves roof timber looking sound but unable to hold a fixing — the same treatment we carry out through nearby Applecross where the timber is worth saving rather than replacing. As registered builders we can certify structural carpentry, which a general handyman can’t, and we assess the whole load path while we’re in the roof space so a repair addresses the cause, not just the symptom. Where a member is load-bearing we prop it safely with acrow props and work to a structural engineer’s design before anything is cut — it’s the natural companion to our tie-down and structural-defect work.

Materials and specification
Runoff carries whatever came off the surface into your stormwater. On larger jobs that silts soakwells and on treated surfaces it carries chemistry as well. Directing it sensibly and rinsing surrounds afterwards is part of the work rather than a courtesy.
A little about Ardross

It does tell us what to expect before we get the ladder out in Ardross.
Recent work


What the work involves
- Work down, never uphill under laps. On any roof or overlapping surface, driving water uphill forces it behind and underneath. That damage is invisible on the day and appears as a stained ceiling weeks later
- Protect surrounds and manage the runoff. Plants covered, windows and fittings protected and the considerable volume of dirty water directed somewhere sensible rather than into a soakwell it will block
- Identify the surface before anything else. Concrete, brick, limestone, render, timber, coated steel and aged roof tile all behave differently under pressure. Asbestos cement is identified and left alone, because cleaning it releases fibres
Common questions about pressure cleaning in Ardross
Where does all the water go?
Into your drainage, carrying whatever came off the surface. On a large job that is a genuine volume and it can silt a soakwell. Managing the runoff is part of doing it properly.
Is soft washing better?
On fragile surfaces, considerably. It applies treatment chemistry at low pressure and lets it work over time, then rinses gently. It takes longer and it does not damage what it is cleaning.
Can you clean before painting?
Yes and preparation is exactly where pressure cleaning earns its place. Coatings adhere to the substrate, not to what is sitting on it.
Can I hire a machine and do it myself?
For a concrete driveway, yes, with a fan tip and sensible distance. For anything on a roof, at height, or on a surface you cannot identify with confidence, the risk of permanent damage outweighs the saving.
What is the difference between pressure and volume?
Pressure is force at the nozzle. Volume is how much water passes. Volume moves debris away, which is why commercial machines outperform domestic units even at similar pressure ratings.
Do you work throughout Ardross?
Yes and the surrounding suburbs. Ring 0421 768 842 and tell us your street. If we are not the right people for the job we will say so rather than quoting anyway.
