Some surfaces should never see a pressure washer at all and asbestos cement is top of that list. On Parkerville properties we identify what we are cleaning before the trigger gets pulled and we will decline work that would cause damage.
Pressure Cleaning in Parkerville: the short version
High pressure suits hard, sound, non porous surfaces. It is wrong for aged tile, brittle terracotta, soft render and anything containing asbestos. More on our pressure cleaning page.
Why Parkerville roofs behave the way they do
On 12 January 2014, during a heatwave of consecutive days above forty degrees, a bushfire started near the corner of Granite. Johnson Roads in Parkerville, believed to have been ignited by a fallen power pole. It destroyed fifty-seven houses and damaged six more across Parkerville, Stoneville and Mount Helena, burning some 386 hectares. The most useful question in Parkerville: did this house survive, or replace one? That fire split the local housing stock in two. There are homes rebuilt since 2014, built to modern bushfire (BAL) construction standards and homes that survived, many of them considerably older and put up long before those standards existed. The two have quite different fire performance and quite different construction, so establishing which you are looking at should come first. On a rebuild, the BAL elements are the ones to examine: ember screening, sealed eaves and roof junctions, rated glazing or shutters, decking and subfloor enclosure and non-combustible cladding where required. Crucially, these only work if maintained, mesh corrodes, seals perish, gutters fill with leaf litter. Verify they are intact, not merely shown on the plans. Overhead power lines crossing or adjoining a treed property are worth noting here for obvious reasons, along with the vegetation clearance around them. Parkerville's older identity is quite different: it grew from the 1895 land release and the railway that opened in 1896. From 1903 was home to Sister Kate's children's home, later the Parkerville Children's Home, whose chapel dates from 1909. It happens quietly. Jane Brook runs through the suburb toward the Swan River, so creek-side blocks carry drainage and flood considerations and hills servicing applies throughout, septic systems, tank or bore water and long driveways.What that means for pressure cleaning in Parkerville
Runoff management matters more on low lying river blocks, where the ground is already holding water and a large volume has nowhere useful to go.
Timber decking is common up here and it raises grain easily. Low pressure worked with the grain, never across it and never with a narrow jet.
Low lying blocks stay damp, so paving and paths green up faster and more persistently than on free draining ground. Treatment beats repeated cleaning here.
Parkerville roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Aged roof tile, chalky | Softened surface layer | Low pressure or soft wash only |
| 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 |
Guide only. Every roof differs, which is why we look before quoting.

Roof Cleaning in Parkerville
Learn moreRoof cleaning strips the moss, lichen and black weathering off a Parkerville 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 Stoneville. 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 Parkerville 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.

Roof Restoration in Parkerville
Learn moreA roof restoration renews a tired but sound Parkerville 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 Mahogany Creek. 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 Parkerville 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 Parkerville
Learn moreMost Parkerville 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 Glen Forrest. 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 Parkerville
Learn moreWhen a Parkerville 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 Hovea, 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 Parkerville
Learn moreA roof inspection is the cheapest way to know exactly what your Parkerville 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 Sawyers Valley, 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 Parkerville

Roof Carpentry in Parkerville
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Parkerville 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 Stoneville 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.

Local conditions in Parkerville
The January 2014 fire destroyed 57 homes here and in the neighbouring suburbs. That has split the housing stock in two: HOMES REBUILT SINCE 2014, constructed to modern bushfire (BAL) construction standards. Same story. HOMES THAT SURVIVED, many of them much older and built long before those standards existed. Establishing which category a property falls into is the single most useful question in Parkerville, the two have very different fire performance and very different construction.
On a post-fire rebuild, the BAL-rated elements are what matter: ember-proof screening, sealed eaves and roof junctions, shutters or rated glazing, decking and subfloor enclosure and non-combustible cladding where required. These are only effective if built and MAINTAINED correctly, mesh corrodes, seals perish, gutters fill with leaf litter. Verify they are intact, not merely present on the plans.
The 2014 fire is believed to have started from a FALLEN POWER POLE. Overhead lines crossing or adjoining a treed property are worth noting, along with vegetation clearance around them.
We cover the whole of the Shire of Mundaring. Around Parkerville that takes in Stoneville, Mount Helena and Jane Brook. Short drives keep pressure cleaning affordable on smaller jobs and most of ours are smaller jobs.
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 Parkerville
On 12 January 2014 a Bushfire started in the Perth Hills, believed to have been caused by a Fallen Power Pole igniting vegetation, during a heatwave of consecutive days over 40°C; the approximate ignition point was on the corner of Granite. Johnson Roads, Parkerville; 57 Houses Were Completely Destroyed and a further six damaged across Parkerville, Stoneville and Mount Helena; ~386 hectares burnt; damage at least A$13 million; one man died while preparing his home for a separate fire In 1903 Katherine Mary Clutterbuck ('Sister Kate') bought about 20 acres and started the 'League of Charity Home' for children. Became the Parkerville Children'S Home; a chapel was completed in 1909; a historic cemetery lies about 3km east; Sally Morgan wrote about the orphanage in 'My Place' None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Parkerville.
Recent work


What the work involves
- 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
- 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
Common questions about pressure cleaning in Parkerville
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.
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.
Do you work throughout Parkerville?
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.
Three questions worth asking first
Ask who will actually be on the roof. Whether the crew are employees or subcontractors matters most when a warranty claim arises, since a workmanship warranty from a business that subcontracts everything and supervises nothing is a document rather than a protection.
