Blasting a roof removes what you can see and leaves what matters. Lichen roots into the surface and grows back through anything applied over it. On Shenton Park roofs we treat first, wait for it to die, then clean properly.
Why Shenton Park roofs behave the way they do
Shenton Park is effectively a suburb of two halves and telling them apart is the whole starting point. On one side there is established character housing, older stock with the solid walls. Suspended timber floors typical of its era, which means a subfloor inspection and attention to rising damp at the base of walls. On the other there is a substantial amount of brownfield redevelopment: a former hospital campus. A former bus depot have both been released for housing, bringing recent apartments and townhouses where institutional and operational buildings once stood. New housing on old working land Ex-institutional and ex-operational sites can carry made ground, demolition fill and buried services beneath the new construction, along with a land-use history worth understanding. None of that makes such housing a poor buy, these sites are generally remediated. Engineered properly, but it does mean the site preparation and slab deserve as much attention as the building above and that asking for the fill and remediation records is reasonable. The two halves also demand different inspections outright: a character house is a freestanding building with a subfloor, while a new apartment is a strata proposition of common property, waterproofing membranes and shared structure. It happens quietly. Around the edges, the rail line brings noise and vibration to nearby blocks, while Karrakatta cemetery provides a permanent open buffer on one boundary. Set back from the coast, salt is a moderate rather than leading concern here, though an older tiled roof still merits a look.Roof Cleaning in Shenton Park: 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 Shenton Park
On a coastal roof we check fixings and valleys while we are up there. Cleaning frequently reveals corrosion that growth had been hiding and it is better found now than through a ceiling.
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.
Glazed terracotta cleans up remarkably well after decades of neglect because the surface was never porous. Unglazed holds staining far more stubbornly and may benefit from a penetrating sealer rather than a coating.
Shenton Park 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 Shenton Park
Learn moreA roof restoration renews a tired but sound Shenton Park 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 Subiaco. 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 Shenton Park 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 Shenton Park
Learn moreMost Shenton Park 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 Daglish. 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 Shenton Park
Learn moreWhen a Shenton Park 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 Floreat, 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 Shenton Park
Learn moreA roof inspection is the cheapest way to know exactly what your Shenton Park 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 Wembley, 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 Shenton Park

Roof Carpentry in Shenton Park
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Shenton Park 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 Jolimont 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 Shenton Park
Learn moreWhen a storm hits a Shenton Park 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 Subiaco. 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.

Local conditions in Shenton Park
Shenton Park contains substantial BROWNFIELD redevelopment, a former hospital campus and a former bus depot released for housing. Ex-institutional and ex-operational land can carry MADE GROUND, demolition fill, buried services and a land-use history worth checking and the new medium-density housing on it inspects completely differently from the surrounding character stock.
The result is a suburb of two halves: established character houses (older solid-walled and timber-floored stock, with subfloor and rising-damp considerations) alongside recent apartments and townhouses (strata, membranes, common property). Establish which before anything else.
Rail line and Karrakatta cemetery form boundaries, near-rail blocks carry noise and vibration; the cemetery provides a permanent open buffer.
We cover the whole of the City of Subiaco. Around Shenton Park that takes in Mount Claremont, Subiaco and Karrakatta. Short drives keep roof cleaning affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
On metal roofs the approach differs entirely. Coated steel does not host growth the way porous tile does and cleaning is about removing deposit rather than killing biology. Lysaght publishes maintenance guidance and near the coast washing sheltered areas that rain does not reach is part of preserving the warranty.
A little about Shenton Park
~3.3km², postcode 6008; bounded by Mount Claremont and Karrakatta (the cemetery) among others; between Subiaco and the western suburbs Major former institutional and operational sites within the suburb have been released for housing, the former Shenton Park hospital campus. A Transperth BUS Depot (replaced by a new Brockway Road facility in Mount Claremont in July 2019) The Register of Aboriginal Sites records a Camp Site in Lemnos Street, Shenton Park; Underwood Avenue nearby was a meeting area and a place of historical and spiritual significance Established character housing with a lake and parkland; near Karrakatta cemetery and the rail line None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Shenton Park.
Recent work


What the work involves
- 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
- Identify what is actually growing. Algae streaks with the slope and is largely cosmetic. Moss holds water and roots in mortar joints. Lichen bonds chemically to the tile and resists physical removal entirely. They need different handling
- 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
Common questions about roof cleaning in Shenton Park
Should I clean or coat?
If the surface is sound and only dirty, clean. If the tiles are porous and darkening after rain, cleaning alone returns you to bare aged tile that starts weathering again immediately.
What about the neighbour's roof?
Spores travel, so a heavily colonised roof next door contributes to yours continuously. You cannot control that, which is why your own conditions matter more.
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.
Do you work throughout Shenton Park?
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 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 Shenton Park roof that difference regularly amounts to thousands.
