Australia's only patented treatment to restore and protect delignified roof timbers, with a 10-year warranty. Serving Aveley 6069 and the eastern hills suburbs.
Fully licensed & accredited — Builders Registration BC105819 · Painters Registration PC102072 · Patent ID AU-A-2020100623
If a building report on your Aveley property flagged delignification, the timber has lost the lignin holding its fibres together. It can be treated rather than torn out. The process is patented, the only one of its kind in Australia and the warranty transfers if you sell.
Why Aveley roofs behave the way they do
Aveley is a masterplanned community of the 2000s and 2010s, it barely existed before 2006 and grew to some fourteen thousand people in little more than a decade. So it is a young suburb and that reshapes the inspection entirely: the findings here are the defects of recent construction and early life, not of age. On a house only ten or fifteen years old, the things worth checking are slab. Footing settlement, articulation-joint cracking and the workmanship of the roof, plumbing and wet areas, the faults that show up in the first years, often just as a builder's warranty period ends. A practical-completion, defect-liability, or careful early pre-purchase inspection is exactly what pays off here. Worth knowing. The ground is the reason to take that seriously. Aveley sits on the Ellen Brook flats, which are reactive alluvial and clay soils with a water table near the brook. Reactive clay under a slab is the classic setting for slab-heave and edge cracking if the site classification, slab design or drainage were not right. On an Aveley home the slab and the site drainage deserve close attention. Many lots are also narrow-lot, with houses close to boundaries and zero-lot walls, which puts a premium on how water is managed in the tight spaces between homes. Being far inland, coastal salt and delignification are a low priority in Aveley. This is a reactive-clay, new-build suburb, the report is about the slab, the drainage and the quality of fairly recent construction.Chemical Delignification Treatment in Aveley: the short version
Lignin is what makes timber rigid. Lose it and the wood still looks like wood while failing to hold anything. This treatment restores and protects the fibres that remain. Background sits on our service page.
What that means for chemical delignification treatment in Aveley
Salt air is part of the exposure history on most affected roofs we assess near the water. Older stock within reach of the sea breeze is where battens most often fail to hold a fixing and the tiles above them are usually perfectly sound.
On reactive ground we look for the water path first. Timber that has been repeatedly wet through a moving junction is where degradation tends to concentrate rather than spreading evenly.
Where the ground stays wet, the air above it does too. That reaches the roof space through every gap and penetration, which is why ventilation forms part of the conversation here.
A coastal roof rarely announces this from outside. The signal is tiles that will not stay put after being reset, which is the batten talking rather than the tile. That warrants a torch and a look in the roof void.
Aveley roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Timber looks bleached or greyish | Surface degradation of the fibres | Treat before it spreads |
| Crumbling with a musty smell | More likely fungal decay than lignin loss | Establish which it is first |
| Fixings spin without gripping | Lignin loss, timber cannot hold a screw | Roof void assessment |
| Timber pulls apart into fibres | Classic delignification signature | Sand back and treat |

Roof Carpentry in Aveley
Learn moreTimber trouble is genuinely uncommon on Aveley's near-new roofs, but when it turns up it's a single install fault — a flashing or valley that's leaked onto a batten since the house went up a few years back. We chase it to that source, replace the wet timber with sound, and fix the detail above, so one build defect doesn't quietly spread through the framing under a young metal roof.

Roof Inspection in Aveley
Learn moreAn Aveley home is usually only a few years old, so a pre-purchase inspection here is really a build-quality check — a fast estate build can leave flashings unsealed, fixings missed and valleys rushed under a tidy-looking dark Colorbond roof. We get onto the sheeting and into the cavity and check exactly those things, then hand you a photographed report, so a young roof's real condition is clear before you offer.

Roof Restoration in Aveley
Learn moreAveley's roofs are far too young for restoration in the tile sense, but there's one thing worth knowing about the dark Colorbond that's standard here: deep colours like Monument show chalking and fade sooner than pale ones under the Perth sun. Years down the track that metal can be cleaned and recoated rather than replaced — a genuine option, though for now these roofs mostly just need their fixings and flashings kept honest.

Roof Replacement in Aveley
Learn moreFull replacement is rare on Aveley's near-new roofs, but a genuinely poor original build or storm damage occasionally forces it — and when it does, we do it right: check the framing and sarking, re-sheet in a properly-specced Colorbond, and detail the flashings and fixings the way a rushed estate build often didn't. Out on the open north-eastern plain we size the hold-down to the wind the estate actually catches.

Learn moreAveley is about as new as Perth gets — 2010s and 2020s estate homes under dark Colorbond, Monument and Woodland Grey. On a roof this young a genuine leak is almost always an install fault, not wear: a flashing not sealed right, a fixing missed, a valley detail rushed on a fast build. We find it, correct the detail properly, and re-secure the sheeting, rather than the silicone dab a builder's warranty call too often gets.

Roof Cleaning in Aveley
Learn moreDark Colorbond like Aveley's shows dust, streaking and the odd mark more than a pale roof does, and the gutters fill fast from young estate landscaping. We wash the sheeting down at a pressure that won't harm the coating, clear the gutters and valleys, and check the fixings and flashings while we're up there — on a metal roof a clean is often when a lifting flashing or a missed fastener first shows.

Signs a Aveley roof needs delignification treatment

- A building inspection flagged delignification
- Soft, fluffy or powdery roof timbers
- Rafters or battens that crumble to the touch
- Buying or selling and it appeared in a report
Local conditions in Aveley
Almost entirely 2000s-2010s stock, young homes. Defects here are NEW-BUILD/early-life: slab and footing settlement, articulation cracking, roof/plumbing workmanship, not age. PCI/defect-liability and early pre-purchase are the relevant scopes.
On the Ellen Brook flats, reactive clay/alluvial ground and a water table near the brook; slab-on-clay performance and drainage are front-line.
Narrow-lot/higher-density masterplanned, zero-lot walls, close boundaries, drainage between houses.
Far inland, salt/delignification low priority; clay/water is the story.
We cover the whole of the City of Swan. Short drives keep chemical delignification treatment affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
You should finish holding documentation: the assessment with photographs of the actual timber, the scope of what was treated and the transferable warranty. That paperwork is what answers a building inspector or a purchaser later and it is worth more than anybody's verbal assurance.

Recent work
What the work involves
- Roof void assessment first. We get into the roof space and test the timber physically rather than looking at it, because affected battens look normal. That establishes how far it has gone and whether treatment suits your roof
- Sand back the affected timber. The degraded surface is removed to reach sound material underneath. This is the stage that separates a genuine treatment from a coat of something sprayed over the problem
Common questions about chemical delignification treatment in Aveley
Can you treat part of a roof?
Where degradation is localised, yes. Where it is widespread the assessment will tell us and the honest answer may be a re-batten and relay instead.
What causes it?
The mechanism is genuinely debated. Prolonged moisture, heat cycling, fungal activity and chemical exposure have all been proposed and affected roofs suggest different combinations. Anyone offering one confident cause for every case is overstating what is known.
Will I need to move out?
No. The work happens in the roof space and the house stays occupied.
How long does it take?
It depends on roof size and how much timber is affected. The assessment gives you a real figure rather than a guess.
Is treatment cheaper than replacing the timbers?
Considerably, in most cases. Treatment preserves what is already there rather than lifting the roof, replacing battens and relaying tiles. Where degradation is too far advanced we will say so.
Do you work throughout Aveley?
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 happens if the scope changes. On older Aveley roofs things become visible once work starts and that is normal. What is not normal is discovering the variation on the invoice. It should be photographed, priced and discussed before anybody acts on it.
