Concrete driveways, paving and masonry take high pressure well. Aged roof tiles, old render and soft timber do not. Knowing which is which is the whole job and on a Bentley home it is the difference between a clean surface and a damaged one.
Pressure Cleaning in Bentley: the short version
Where a surface is too fragile for pressure, soft washing does the work chemically instead and takes longer. It looks less impressive on the day and it is better for the building. Full detail on our pressure cleaning page.
Why Bentley roofs behave the way they do
Bentley is shaped by two forces that set it apart. The first is Curtin University, whose main campus and Technology Park sit in the suburb and drive a large student rental market. For an inspection that means a lot of investor and tenanted stock, with the patterns that come with it: deferred maintenance. Houses that have been informally converted or sub-divided for shared student living, worth checking that any such changes were done properly and approved. The second is its history as a public-housing suburb. The State Housing Commission developed Bentley from the 1940s, including war service homes for returning WWII veterans, some of which remain. So a good deal of the stock is modest post-war fabric, seventy to eighty years old, where asbestos-era materials are likely and services are well past their first life. The landmark Brownlie Towers public-housing flats were removed in 2019 and that precinct and others are being redeveloped into new medium-density infill, so newer strata now sits beside the old homes. Nothing dramatic. Being inland, coastal salt and delignification are a low priority in Bentley. The report here turns on which Bentley you are buying, an ageing war-service or Homeswest house, a student-rental conversion, or new infill and on the age and honesty of any alterations.What that means for pressure cleaning in Bentley
Where a roof is being cleaned before coating near the water, washing salt off properly is the step that determines whether the coating holds. Coating over salt residue puts a release layer under the membrane.
Concrete tile from this era has usually lost its factory surface, which means the material underneath is porous and soft. That is exactly the surface high pressure damages.
On strata properties the common areas, paths, car parks and shared paving are scheduled work rather than one off and doing the whole complex at once is cheaper per dwelling.
Bentley roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Limestone, historic | Soft and permeable | Specialist approach, not high pressure |
| Concrete driveway, general grime | Sound surface, hard wearing | High pressure, fan tip |
| Slippery paving on the shaded side | Algae holding moisture | Treat, then clean at moderate pressure |
| Aged roof tile, chalky | Softened surface layer | Low pressure or soft wash only |
Guide only. Every roof differs, which is why we look before quoting.

Roof Cleaning in Bentley
Learn moreBentley roofs carry the usual weathering plus, on long-held rentals, years of neglected moss that's rooted well into the tile. We treat it so it dies at the root rather than greening back, then wash the roof to an even colour at a safe pressure. On a rental it's a cheap way to lift the property between tenancies; on an owner's home it's the sensible first step before any coating.

Roof Restoration in Bentley
Learn moreA lot of Bentley's older homes and long-held rentals are well overdue for a restoration — years of deferred upkeep showing as dead colour and failing pointing over sound tiles. We kill the growth so it stays gone, set the ridges and cracked tiles right, then seal and coat the roof. For a fraction of a re-roof it lifts a tired home or rental noticeably, and protects the tiles from further neglect.

Roof Repairs in Bentley
Learn moreBentley is a real mix — older homes, a lot of rental and investment stock near the university, and pockets being redeveloped — and rentals in particular tend to carry deferred roof problems, because small leaks get put off. So repairs here are often a backlog: perished pointing, cracked tiles, a flashing that's been weeping a while. We sort the real source, match the tile, and re-point properly, rather than the quick patch a rental has usually already had.

Roof Replacement in Bentley
Learn moreWhen a Bentley roof is genuinely spent — often one that's been patched rather than maintained for years — we replace it and put right what the deferred upkeep let slide: fresh sarking, sound framing, and properly detailed flashings and valleys, with a straight steer on tile versus lighter Colorbond. Whether it's an owner-occupier or an investment property, the aim is a roof that's done once and stops the recurring call-outs.

Roof Inspection in Bentley
Learn moreBuying in Bentley often means an older home or a former rental, and rentals in particular hide deferred roof problems behind a quick tidy-up, so an inspection before you sign matters. We check the tiles, pointing, valleys and flashings and get into the cavity for the sarking and framing, then hand you a photographed report — so a property that's been patched to sell doesn't become your problem after settlement.

Roof Carpentry in Bentley
Learn moreOn a Bentley rental or older home, a leak that's been left rather than fixed will often have reached the timber — a rafter or batten softened by water that dripped for a season or three. We cut back to sound wood, splice or replace to match, and shut off the leak at its source, turning years of deferred neglect into a proper, lasting repair rather than another patch.

Surfaces around a Bentley home that come up well
- A patio or alfresco that has stopped looking maintained
- Surfaces being prepared before sealing or painting
- Driveways and paths stained grey or green
- Black streaking down rendered or painted walls
- Paving that has become slippery underfoot
Local conditions in Bentley
1940s-50s State Housing Commission + WAR SERVICE HOMES, modest, older post-war fabric (~70-80 years); asbestos-era materials likely; ex-Homeswest construction patterns.
Curtin drives heavy student RENTAL/investor stock, deferred maintenance, converted/sub-divided houses, HMO-style wear; check for informal conversions.
Ex-Brownlie Towers precinct + public-housing renewal = new medium-density infill beside old stock; new strata.
We cover the whole of the City of Canning. Short drives keep pressure cleaning affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
Insurance is worth checking specifically. Public liability alone may not cover damage to the surface being worked on and pressure damage to render, tile or timber is difficult to argue about after the fact. Photographs before starting protect both parties.
A little about Bentley
1940s-50s SHC + war-service homes + post-war + student rentals + new infill (ex-Brownlie Towers site redeveloping); lower-income, diverse Convict road-camp origins ('Bentley Hill' from 1860s, after warder John Bentley); 1880s dairy/piggery; WA's first drive-in theatre None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Bentley.
Recent work
What the work involves
- 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
- Match nozzle and standoff to the surface. A pencil jet concentrates enormous force into a tiny area and will carve concrete. A fan tip spreads the same energy across a band. Doubling the distance from the surface dramatically reduces impact force
Common questions about pressure cleaning in Bentley
Why does the nozzle matter so much?
It determines how the same energy is delivered. A narrow jet concentrates it and will gouge. A wider fan spreads it across a band and cleans without cutting. Turbo tips belong on driveways and never on roofs.
Will it damage my mortar?
It can. Aged mortar in brickwork or paving joints is softer than the material around it and washes out under a concentrated jet. That is repointing work created by the cleaning.
What about asbestos?
Never pressure clean it. Cleaning fibre cement sheeting releases fibres and it is both dangerous and unlawful. We identify suspected material and decline the work rather than proceed.
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.

How to tell a real assessment from a sales visit
Be wary of urgency. Nobody legitimate needs a decision on the day and a discount valid only this afternoon tells you something about the rest of the transaction. Written quotes on Bentley properties should stay open long enough for you to get a second opinion.
