Quick answer

Some surfaces should never see a pressure washer at all and asbestos cement is top of that list. On Serpentine properties we identify what we are cleaning before the trigger gets pulled and we will decline work that would cause damage.

Pressure Cleaning in Serpentine: the short version

Standoff distance moderates force more than the machine setting does, which is how an experienced operator varies intensity continuously without touching a dial. Background on our service page.

Why Serpentine roofs behave the way they do

Serpentine gives the shire its name but was never its biggest town, it is a rural district on the river of the same name, settled from 1893 and built on dairying. Its landmark is the cheese factory opened in 1932 by the Premier of the day, which was then the only operating cheese factory in Western Australia and ran until 1951. That agricultural history is what an inspection actually meets. It happens quietly. Properties here often come with old farm buildings as well as a house, dairies, milking and hay sheds, stables, sometimes a workers' cottage, typically built of early timber, corrugated iron and soft brick. These are frequently unmaintained, sometimes unapproved and they need to be assessed properly or explicitly excluded from the report, because a buyer who assumes a shed is sound can inherit an expensive problem. The Serpentine River brings a flood context to the low river flats, along with alluvial soils. Seasonally high groundwater near the water, though the district is dry enough that the river famously stopped flowing altogether in the summer of 1940-41. Rural holdings here are generally unsewered, so confirming the effluent system, water supply and private services (and the age of each) matters as much as the house. With bushland and the Darling Scarp to the east, both bushfire exposure and termite pressure are genuine, while the coast is far enough away that salt plays no part at all.

What that means for pressure cleaning in Serpentine

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.

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.

Runoff has nowhere to drain on saturated ground, so managing where several hundred litres ends up is a real consideration rather than an afterthought.

Roof cleaning strips the moss, lichen and black weathering off a Serpentine 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 Mardella. 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 Serpentine 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 Serpentine

A roof restoration renews a tired but sound Serpentine 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 Hopeland. 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 Serpentine 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 Serpentine

Learn more

Most Serpentine 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 Baldivis. 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 Serpentine

Learn more

When a Serpentine 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 Karnup, 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 Serpentine

A roof inspection is the cheapest way to know exactly what your Serpentine 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 Keysbrook, 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.

Roof Carpentry in Serpentine

Learn more

Roof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Serpentine 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 Mardella 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.

Surfaces around a Serpentine home that come up well

  • 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
  • Brickwork carrying years of accumulated grime

Local conditions in Serpentine

A rural dairying district since the 19thC, expect old FARM buildings alongside houses: dairies, milking sheds, hay sheds, stables and workers' cottages, often of early timber, iron and soft brick. These outbuildings are frequently unmaintained and sometimes unapproved; they need assessing (or excluding) explicitly.

On the Serpentine River, riverine flood context on low-lying river flats; check flood levels and expect alluvial soils with seasonally high groundwater near the river.

Rural holdings, septic/leach systems, bore and tank water, long private drives, private power runs; confirm what is connected and the age of each system.

We cover the whole of the Shire of Serpentine-Jarrahdale. Around Serpentine that takes in Perth, Mundijong and Byford. Short drives keep pressure cleaning affordable on smaller jobs and most of ours are smaller jobs.

Materials and specification

Where cleaning is preparation for a roof coating, the sequence matters more than the equipment. Treat growth, wait for it to die, clean at a pressure suited to the tile, then seal and apply the Dulux AcraTex system under accreditation. Cleaning alone returns a roof to bare aged tile that starts weathering again immediately.

A little about Serpentine

The Serpentine Cheese Factory, originally the idea of Arthur Middleton and neighbours, officially opened by Premier James Mitchell on 8 August 1932; at the time the Only operating cheese factory in WA; operated until 1951; now Shire heritage-listed On the Serpentine River (Serpentine Dam and Falls in the ranges to the east); in the summer of 1940/41 the Serpentine river Stopped Flowing for the first time since 1914 Rural/agricultural district, dairying heritage; scattered farms and rural-residential holdings; South Western Highway corridor None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Serpentine.

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 Serpentine

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.

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.

Do you work throughout Serpentine?

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.

Before you commit to anybody

Three questions separate a genuine assessment from a sales visit and they apply to us as much as to anyone else. Which specific component has failed, rather than a general statement about age. Whether somebody entered the roof space, because batten condition cannot be judged from outside. And whether photographs exist. Clear answers to all three usually mean somebody looked properly.
