Three different organisms grow on Perth roofs and only one washes off. Moss sits on the surface, algae streaks down it and lichen bonds chemically into aged tile. Powerdrive treats growth so it dies, then cleans at a pressure matched to the tile. Free inspection across Wilson.
Why Wilson roofs behave the way they do
Wilson has an unusually concentrated building history: after being farmland until the war, it was largely built in one burst, 600 houses between 1959. 1964, a great many of them State Housing Commission homes. That means much of Wilson is near-identical late-1950s and early-60s stock: modest, single-storey, built to the Homeswest patterns of the day, with original services now around sixty years old and asbestos-era materials likely throughout. When a suburb goes up in one short window like this, the same age-related items tend to come due across whole streets at once, roofs, wiring, hot water, which is worth bearing in mind. Wilson sits on the Canning River and it has a distinctive piece of river infrastructure: the Kent Street Weir, in place since 1927 to hold back summer salt-water intrusion up the river. It shows. It was only partly successful, but it shaped the suburb's relationship to the water. For an inspection, the low river-flat blocks carry the usual concerns, a water table, a flood context and subfloor damp, regardless of the weir. Wilson is also popular with Curtin University students, so there is a real rental share, with the deferred maintenance. Informal sharehouse conversions that come with it, worth checking any such changes were done properly. Being a river suburb rather than a coastal one, salt-driven delignification is a low priority; Wilson's report is about a concentrated batch of ageing 1959-64 homes on river-flat ground.Roof Cleaning in Wilson: the short version
A clean roof lasts longer and not for cosmetic reasons. Growth holds water against the surface indefinitely. Full detail on our roof cleaning page.
What that means for roof cleaning in Wilson
Mature canopy through these suburbs adds shade and constant leaf drop, which is the combination that keeps a roof surface hospitable year round.
Treatment needs a dry stretch to work and on these blocks that window is narrower than most people expect. We schedule around it rather than forcing it.
On character roofs the aim is the same building, cleaned, rather than a different one. Nobody passing should be able to tell work was done.
Wilson roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Dark patches back within two years | Growth was removed but never killed | Treat properly this time |
| Tiles darken and stay dark after rain | Porous surface absorbing water | Clean, then seal and coat |
| Growth only on one elevation | Shaded plane holding moisture | Treat that side, consider the canopy |
| Roof clean but gutters full of grit | Surface breaking down | Assess whether coating is due |
Guide only. Every roof differs, which is why we look before quoting.

Roof Restoration in Wilson
Learn moreA roof restoration renews a tired but sound Wilson 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 East Cannington. 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 Wilson 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 Wilson
Learn moreMost Wilson 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 Queens Park. 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 Wilson
Learn moreWhen a Wilson 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 Cannington, 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.

04Roof Inspection in Wilson

Roof Inspection in Wilson
Learn moreA roof inspection is the cheapest way to know exactly what your Wilson 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 Wattle Grove, 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.

05Roof Carpentry in Wilson

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

Storm Damage Repair in Wilson
Learn moreWhen a storm hits a Wilson roof — lifting ridge caps, cracking tiles or dropping a limb through it — our first job is always to make the roof safe: tarp the opening, stop the water, and take the immediate danger out of it. Only then do we scope the permanent repair and deal with your insurer.
We document the damage thoroughly, separating genuine storm damage from pre-existing wear so the claim is properly supported, and we check the framing around any impact because a limb strike shock-loads more than the visible hole. It’s the same rapid response we bring to nearby East Cannington. Getting there quickly limits the internal damage — an hour of water ingress can mean ceilings and insulation you’ll otherwise be replacing later. We liaise with your insurer directly and hand back a documented, photographed scope, so the claim is straightforward and the repair holds up in the next blow rather than becoming the next emergency.

- Green or grey patches on the shaded southern side
- Growth visible in the ridge and hip mortar joints
- Tiles staying dark for hours after rain
Local conditions in Wilson
A concentrated 1959-64 building batch, much of it State Housing Commission, so a lot of near-identical late-50s/early-60s modest homes: original services now ~60 years old, ex-Homeswest patterns, asbestos-era materials likely.
Canning River + Kent Street Weir, river-flat blocks: water table, flood context; the weir holds fresher water upstream but the low ground is still wet ground.
Curtin student rental share, deferred maintenance, informal sharehouse conversions to check.
We cover the whole of the City of Canning. That takes in Queens Park and the streets around Wilson. Short drives keep roof cleaning affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
If the roof is being cleaned ahead of coating, colour is worth thinking about at the same time. The AcraTex roofing colour range is published in full and darker tones conceal organic staining better under heavy canopy.
A little about Wilson
Favoured by Curtin University students (close access), rental market; riverside parks (Kent St Weir, Lo Quay) On the Canning River; Kent Street Weir (operating by 1927) built to prevent summer Salt-Water intrusion up the river (only partly successful, popular swimming spot); Castledare (~1907 'Balmoral', later Catholic boys' home, now aged care) 1959-64 SHC + post-war + later infill; riverside; multicultural/student rental None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Wilson.
Recent work


What the work involves
- Treat, then wait. A biocide kills the organism including whatever is bonded into the surface. That takes days, not minutes and it is the stage that separates a lasting clean from a cosmetic one
- Clean at a pressure matched to the tile. Aged concrete that has been damp for decades has a softened surface. Excessive pressure removes material rather than dirt and drives water up under the laps into the roof space
- Clear up afterwards. A clean produces a considerable quantity of debris that goes straight into your gutters and downpipes. Flushing them is part of the job rather than an extra
Common questions about roof cleaning in Wilson
How often should a roof be cleaned?
It depends on aspect, canopy and whether the surface is sealed. An open aspect coated roof may go many years. Aged unsealed tile under heavy trees on a shaded side needs it far sooner.
Will cleaning damage my tiles?
Done at appropriate pressure with proper treatment, no. Done aggressively on aged concrete, yes and the damage is permanent. It strips the surface and leaves the roof more hospitable to growth than before.
Why does growth come back so quickly?
Usually because it was blasted rather than killed. Lichen in particular regrows from what remains bonded to the tile and a roughened surface gives spores more to hold onto.
Is it safe for my garden?
With proper protection and a thorough rinse down, yes. It is a fair question to ask any contractor before they start and isolating a rainwater tank is sensible.
Do you work throughout Wilson?
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.
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 Wilson properties should stay open long enough for you to get a second opinion.
