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 Maddington.
Roof Cleaning in Maddington: the short version
Aged concrete tile is porous once its surface has gone, which is what lets growth take hold. Cleaning addresses the symptom and sealing addresses the cause. More on our cleaning page.
Why Maddington roofs behave the way they do
Maddington carries the oldest name in the Gosnells area, it was “Maddington Park” back in the 1830s, but for an inspection its defining quality is that it is genuinely mixed-use. The suburb holds residential, retail, industrial and even semi-rural land side by side and that matters: a house here can adjoin the industrial estate. Raises questions of industrial-edge context, noise and ground history on or near former-industrial parcels. That industrial estate has a specific origin worth knowing, it was built from the 1970s on the land of the old Canning Park Racecourse. At the other end of the spectrum, Maddington still retains vineyards, orchards and semi-rural pockets from its agricultural past. Nothing dramatic. On those large-lot properties the inspection shifts to septic systems, bores, sheds and outbuildings and to former horticultural ground, old irrigation and, on some parcels, the residues of past orchard chemicals. So which Maddington you are buying, suburban, industrial-edge, or semi-rural, changes the whole job. Underneath it all is the Pinjarra Plain reactive clay of the Canning catchment, so footing and slab movement is the baseline structural concern, as across the southeast corridor. Transit-oriented development around the station is also adding density. Being inland, salt-driven delignification is a low priority; Maddington's report is about which land-use zone the block sits in, the ground history that comes with it and the reactive clay beneath.What that means for roof cleaning in Maddington
Rinsing sheltered metalwork is worth doing at the same time. Twenty minutes with a hose twice a year does more for a coastal roof than most owners expect.
Where seasonal movement has cracked ridge mortar, growth establishes in the openings and holds water directly against the failing joint. Cleaning helps and re-pointing is what actually fixes it.
Growth in the ridge joints on these roofs is worth noting, since it indicates mortar that has broken down enough to hold moisture and support a plant.
Maddington roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| 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 |
| Dark vertical streaks | Algae, spreading with each rainfall | Treat and wash |
Guide only. Every roof differs, which is why we look before quoting.

Roof Restoration in Maddington
Learn moreA roof restoration renews a tired but sound Maddington 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 Orange Grove. 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 Maddington 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 Maddington
Learn moreMost Maddington 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 Martin. 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 Maddington
Learn moreWhen a Maddington 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 Huntingdale, 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 Maddington

Roof Inspection in Maddington
Learn moreA roof inspection is the cheapest way to know exactly what your Maddington 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 Southern River, 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 Maddington

Roof Carpentry in Maddington
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Maddington 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 Gosnells 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 Maddington
Learn moreWhen a storm hits a Maddington 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 Orange Grove. 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.

We cover the whole of the City of Gosnells. That takes in Gosnells and the streets around Maddington. Short drives keep roof cleaning affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
Where cleaning reveals broken tiles, matching runs through Bristile Roofing or salvage stock at Roof Top Industries. Growth frequently hides damage, so it is common to find more once a roof is clean.
A little about Maddington
Mixed-USE: major residential, retail (Maddington Central) AND industrial sections + semi-rural; retains several Vineyards and Orchards from its agricultural past 1950s-60s subdivision onward; residential + industrial + semi-rural orchard/vineyard pockets; TOD planning at the station Oldest name in the Gosnells area, John Randall Phillips named 'Maddington Park' (after a Wiltshire town) in the 1830s; subdivided ~70 years later after the gold rush None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Maddington.
Recent work


What the work involves
- 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
- 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
Common questions about roof cleaning in Maddington
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.
Can I do it myself?
The chemistry is available. The height is the problem and mossy tile in the wet is genuinely treacherous. Ladder falls at home are common and serious.
Do you work throughout Maddington?
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
Compare scopes rather than totals. A cheaper quote is frequently a different job and the gap is usually treatment time, film build, or repairs excluded and raised later. Ask for the product name, coat count and what happens if more damage is found once work starts.
