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 Martin.
Roof Cleaning in Martin: the short version
Cleaning a roof properly is mostly waiting. The treatment has to kill the growth before anything is washed, or it regrows from what remains. Detail sits on our roof cleaning page.
Why Martin roofs behave the way they do
Martin is rural and semi-rural country in the foothills of the Darling Scarp rather than a suburb of streets. That changes the whole shape of an inspection: here the property is the job, not just the house. Expect septic or aerobic treatment systems, bore or tank water, dams, long private driveways and substantial outbuildings, sheds, stables, machinery storage, that are frequently owner-built, unengineered and sometimes never approved. Those structures need assessing explicitly or excluding explicitly, because a buyer who assumes a large shed comes with the land in sound condition can inherit a significant cost. The ground is the second defining factor. Worth knowing. At the foot of the scarp, the material underfoot shifts over short distances between coastal-plain soils and foothill granite and laterite. That makes differential founding, part of a structure bearing on solid rock, part on soil or fill, a realistic cause of cracking that has nothing to do with the quality of the building. It means excavation costs for any future work vary enormously from one property to the next. Tributaries of the Canning system cross the district, so low ground near watercourses carries a seasonally high water table, winter wet. Overland flow, while land on the rising side brings slope, retaining and cut-and-fill instead. With bushland and state forest on the scarp side, bushfire exposure is genuine and termite pressure high. The practical realities of distance apply too, with slower emergency response and real difficulty getting trades to attend for small jobs.What that means for roof cleaning in Martin
Sea air keeps surfaces damp overnight even where rainfall is modest, which supports algae on elevations that would stay clean further inland.
This is the part of Perth where lichen genuinely establishes rather than sits. River air keeps roofs damp into the morning and shaded planes barely dry at all through winter, which is exactly what it needs.
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.
Martin roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Dark vertical streaks | Algae, spreading with each rainfall | Treat and wash |
| Green cushions in the ridge joints | Moss holding water against mortar | Treat, clean, then re-point |
| Flat grey or sage crusty patches | Lichen bonded into the tile | Treat and wait, never blast |
| Dark patches back within two years | Growth was removed but never killed | Treat properly this time |

Roof Restoration in Martin
Learn moreA roof restoration renews a tired but sound Martin 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 Huntingdale. 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 Martin 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 Martin
Learn moreMost Martin 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 Southern River. 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 Martin
Learn moreWhen a Martin 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 Gosnells, 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 Martin

Roof Inspection in Martin
Learn moreA roof inspection is the cheapest way to know exactly what your Martin 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 Orange 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 Martin

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

06Storm Damage Repair in Martin

Storm Damage Repair in Martin
Learn moreWhen a storm hits a Martin 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 Huntingdale. 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 Martin
Martin is rural and semi-rural rather than suburban, so the PROPERTY IS THE INSPECTION, not just the house. Expect SEPTIC OR AEROBIC TREATMENT SYSTEMS, BORE OR TANK WATER, dams, long private driveways and substantial outbuildings, sheds, stables, machinery storage, that are frequently owner-built, unengineered and sometimes unapproved. These need assessing explicitly or excluding explicitly.
At the foot of the Darling Scarp, ground shifts over short distances between coastal-plain soils and foothill GRANITE AND LATERITE. That makes DIFFERENTIAL FOUNDING, part of a structure bearing on rock, part on soil or fill, a realistic cause of cracking that has nothing to do with build quality. It means excavation costs vary enormously across the locality.
Tributaries of the Canning system cross the district, low ground near watercourses carries a seasonally high water table, winter wet and overland flow, while land on the rising side brings slope, retaining and cut-and-fill.
Bushland and state forest on the scarp side, genuine bushfire (BAL) exposure, high termite pressure and the practical realities of distance: slower emergency response and difficulty getting trades out for small jobs.
We cover the whole of the City of Gosnells. Around Martin that takes in Gosnells, Kenwick and Orange Grove. 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 Martin
Near Bickley Brook and the Canning River catchment; adjoins state forest and reserve land on the scarp side; served by roads rather than public transport of any density None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Martin.
Recent work


What the work involves
- 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
- 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
Common questions about roof cleaning in Martin
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.
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.
Do you work throughout Martin?
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.
Checking the quote before you sign
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 Martin roof that difference regularly amounts to thousands.
