Some surfaces should never see a pressure washer at all and asbestos cement is top of that list. On Subiaco properties we identify what we are cleaning before the trigger gets pulled and we will decline work that would cause damage.
Why Subiaco roofs behave the way they do
Subiaco is one of the most heavily heritage-listed local government areas in the state: 928 places are listed, thirty of them on the State Register. Whole precincts have been listed collectively, the Park Street Heritage Area alone added 109 properties. Check the heritage status of the address before anything else With listing at that density, the chance a Subiaco property carries some form of heritage status is substantial. It may be listed as part of a precinct rather than individually, which owners frequently do not realise. Listing constrains what can be altered and requires repairs in materials compatible with the original construction. Establishing the status of the specific address and what it actually permits, should come before any renovation planning. The character stock is late-Victorian and Federation: solid brick without cavity or damp-proof course, timber floors on stumps, original iron or tile roofs. Every time. So rising damp, subfloor condition and the genuine cost of heritage-compatible repair are the recurring findings. One part of Subiaco is entirely different. Subi Centro was built on reclaimed industrial land around a sunken railway station, so there the housing is modern apartment strata on made ground. Engineered fill, a completely different inspection and one where site history is a reasonable question. Major hospital and school precincts sit within and beside the suburb, bringing traffic, parking pressure and a substantial rental share to nearby streets. (A historical note that says something about the place: when Leederville, North Perth and Victoria Park were absorbed into the City of Perth, Subiaco held a referendum in 1935 and voted 73 per cent against.)Pressure Cleaning in Subiaco: 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.
What that means for pressure cleaning in Subiaco
Original terracotta is brittle and chips under concentrated pressure. Where a heritage roof needs cleaning, chemistry and low pressure is the only sensible route.
Runoff in a shared property affects neighbours, so containment and timing need agreeing rather than assuming.
Metalwork here is frequently already compromised by corrosion, so pressure that would be safe elsewhere can drive water behind failing edges.
Subiaco roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| 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 |
| Old render, powdery to touch | Substrate already failing | Do not pressure clean, assess first |
Guide only. Every roof differs, which is why we look before quoting.

Roof Cleaning in Subiaco
Learn moreSubiaco's leafy, shaded streets are lovely to live on and perfect for growing moss on a roof, especially the southern pitches of the older homes. We treat the growth so it dies at the root instead of greening back after the next rain, then clean carefully — a lot of these are older, porous terracotta roofs that won't take a heavy blast — and clear the leaf litter the street trees drop. Often a careful clean is all a tidy older roof genuinely needs.

Roof Restoration in Subiaco
Learn moreA restoration on a Subiaco character home is really a careful renewal — the roofs are often original, the streets are leafy, and the houses deserve a considered hand. We treat the moss the shade encourages, clean back to sound tile, re-bed and re-point ridge caps loosened over the decades, replace the terracotta that's spalled, and finish in a colour that suits the house and the street. Done well it protects a lovely old roof for years; done carelessly it looks wrong on a home like this, and people notice.

Roof Repairs in Subiaco
Learn moreSubiaco is full of Federation and character homes, and their roofs fail in character ways — a cracked terracotta tile off a steep gable, perished pointing along an old ridge, tired flashing round a chimney that's finally let go. We work carefully on these older roofs, match the profiles where we can, and trace the leak back to where the water actually enters rather than sealing the stain inside. On a heritage street the repair has to look right as much as hold, and that's how we approach it.

Roof Replacement in Subiaco
Learn moreWhen a Subiaco roof is genuinely past saving, a re-roof has to respect what the house is. We'll talk through keeping a terracotta look or moving to Colorbond for the weight, sort the old framing and flashings properly underneath, and mind any heritage considerations before we start. The result is a roof that fits one of Perth's most characterful suburbs and takes the house comfortably into its next chapter, rather than a modern lid slapped on an old cottage.

Roof Inspection in Subiaco
Learn moreBuying a Subiaco character home means buying an older roof, and it pays to know exactly what that involves before you sign. We inspect on top and inside the roof space and look hard at the things these places hide — tired flashings, cracked terracotta, perished pointing, and the state of old jarrah framing — then give you a plain written report with photos. On a heritage home the roof is often the biggest unknown, and knowing beforehand puts you in a far better spot.

Roof Carpentry in Subiaco
Learn moreUnder a lot of Subiaco's older roofs is beautiful old jarrah framing that's quietly weathered a century and the odd slow leak. When a rafter's softened under a failed valley or a batten's given way, it needs someone who'll repair it properly rather than prop it and move on. We cut back to sound timber, splice or replace to match, and fix whatever let the water in above it, keeping the structure honest under a roof that's worth preserving.

Local conditions in Subiaco
With 928 heritage-listed places in the local government area and whole precincts listed collectively, the odds that a Subiaco property carries some heritage status are substantial. Listing constrains what may be altered and requires materials compatible with the original construction. The FIRST STEP HERE IS CHECKING THE HERITAGE STATUS OF THE SPECIFIC ADDRESS, including whether it falls within a listed precinct rather than being individually listed.
The character stock is late-Victorian and Federation, solid brick without cavity or damp-proof course, timber floors on stumps, original iron or tile roofs. Rising damp, subfloor condition and the cost of heritage-compatible repair are the recurring themes.
Subi Centro was built on RECLAIMED INDUSTRIAL LAND around a sunken railway station, so on that side of the suburb expect made ground, engineered fill and modern apartment Commercial Roofing Perth rather than character housing. Site history is a fair question there.
We cover the whole of the City of Subiaco. Around Subiaco that takes in Wembley, Shenton Park, Perth, Leederville, North Perth and Victoria Park. Short drives keep pressure cleaning affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
On metal roofing and cladding, cleaning is about removing deposit rather than killing biology. Lysaght publishes maintenance guidance and near the coast washing the sheltered areas rain never reaches is part of preserving a product warranty rather than an optional extra.

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 Subiaco
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.
Do you work throughout Subiaco?
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
Ask what was actually inspected. A quote produced from the footpath, a photograph or satellite imagery is a guess, because mortar condition, valley corrosion and batten integrity determine most of the work and none can be assessed remotely. On a Subiaco roof that difference regularly amounts to thousands.
