Most people call a roofer when something leaks. An inspection is what tells you what is coming before it does and on Treeby homes it routinely finds problems a year or two before they reach a ceiling.
Roof Inspection in Treeby: the short version
Photographs matter more than opinions. You cannot see your own roof, so evidence is the only way to judge what you are told. Background on our service page.
Why Treeby roofs behave the way they do
Treeby only became a suburb in 2016, carved from the part of Banjup north of Armadale Road, so essentially everything here is recent construction. But its most important characteristic is what lies underneath it. Much of Treeby is built on former sand-mining land Land in the suburb that had been mined for sand was subsequently developed into residential estate. Extraction and reinstatement leave a distinctive legacy: variable fill depth, reconstructed ground profiles and founding conditions that can differ across a single lot. On any recent slab here, the first things to establish are the site classification. The depth and compaction of fill beneath it and asking the vendor or developer for the geotechnical and fill records for that parcel is an entirely reasonable request, not an awkward one. The scale of building is worth knowing too: more than 1,100 house-and-land packages have been sold in Treeby, with a large display village operating in the suburb. Volume building at that scale is not poor building, but it does mean consistent specification at a price point. The elements typically built to minimum standard repay attention: wet-area waterproofing, roof plumbing and flashings and the junctions between them. It is avoidable. Because the housing is so young, the useful inspections are the new-build ones: at practical completion before the final payment and again before the builder's defect-liability period expires. Where a home adjoins ongoing construction, a dilapidation record taken beforehand gives a dated baseline. On the northern boundary, the Jandakot Industrial Area brings heavy-vehicle traffic and industrial operating hours to that edge of the suburb.What that means for roof inspection in Treeby
Free draining ground removes the movement question, so an assessment here concentrates on the roof itself rather than untangling what the soil has been doing to it.
Old terracotta is brittle and steep pitches are common, so these inspections are worked from above rather than walked casually. It takes longer and it protects tiles that cannot easily be replaced.
Metalwork deteriorates faster in this environment than a generic maintenance interval assumes, so inspections here concentrate on fixings, flashings and valleys rather than the covering.
Treeby roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Building report flagged the roof | Identified but rarely scoped | Specialist assessment and quote |
| Quoted a replacement, unsure | Age often mistaken for failure | Independent second opinion |
| Intermittent leak, no pattern | Entry point not yet traced | Roof space inspection with a torch |
| Selling within a year | Inspectors flag pointing and valleys | Pre-sale assessment |
Guide only. Every roof differs, which is why we look before quoting.

Roof Repairs in Treeby
Learn moreMost Treeby 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 Aubin Grove. 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 Restoration in Treeby
Learn moreA roof restoration renews a tired but sound Treeby 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 South Lake. 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 Treeby 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.

03Roof Replacement in Treeby

Roof Replacement in Treeby
Learn moreWhen a Treeby 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 Jandakot, 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 Carpentry in Treeby

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

Structural Defect Repairs in Treeby
Learn moreWhen a building or pest inspection flags a roof-framing defect — a sagging rafter, a cut truss, inadequate bracing, rot or termite damage — the REIWA contract needs it rectified before settlement, and in Western Australia that rectification must be certified by a registered builder. Powerdrive holds Builders Registration BC105819, so we can both rectify the fault and certify it for your Treeby sale.
We assess the defect, bring in a structural engineer where a load-bearing member is involved, and put it right — propping, sistering, reinstating cut members and adding the connections the frame needs. It’s the same certified rectification we handle through nearby Hammond Park. An unregistered handyman can patch the timber but can’t certify it, which is exactly what stalls a settlement. An engineering assessment typically runs $800 to $2,000 and gives everyone a defined scope, and we hand back a documented record you can pass straight to the buyer — so it’s done once, properly.

Storm Damage Repair in Treeby
Learn moreWhen a storm hits a Treeby 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 Aubin 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.

When a Treeby roof is worth having inspected
- Nobody has been on the roof in ten years or more
- A leak that comes and goes without an obvious cause
- Storm damage that needs documenting for an insurer
- A quote you would like a second opinion on
- Tiles visibly slipped or mortar debris in the gutters
Local conditions in Treeby
A substantial part of Treeby's housing stands on land that was PREVIOUSLY MINED FOR SAND. Extraction and reinstatement leave a distinctive legacy: variable fill depth, RECONSTRUCTED GROUND PROFILES and founding conditions that can differ across a single lot. On any recent slab here, SITE CLASSIFICATION and the DEPTH AND COMPACTION OF FILL are the first things to establish and asking for the geotechnical and fill records for the parcel is entirely reasonable.
Over 1,100 house-and-land packages have been sold here and a large display village operates in the suburb, so this is volume building at scale. That is not poor building, but it means consistent specification at a price point, check WET-AREA WATERPROOFING, ROOF PLUMBING AND FLASHINGS and junctions and inspect at handover and again before the defect-liability period ends.
The suburb was only created in 2016, so essentially all housing is recent, new-build inspections apply and where a home adjoins ongoing construction, a dilapidation record beforehand is worthwhile.
We cover the whole of the City of Cockburn. Around Treeby that takes in Cockburn Central and Banjup. Short drives keep roof inspection affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
Where the assessment leads to a coating, we apply the Dulux AcraTex system under accreditation, which is what makes the manufacturer warranty available on your roof. The warranty terms are published in full and worth reading before committing to anybody.
A little about Treeby
Bounded in the north by the eastern border of the Jandakot Industrial Area, Dollier Street and Fraser Road Land in the suburb that had been Mined FOR Sand was developed into a new residential estate called Calleya; Stockland has sold Over 1,100 House. Land Packages in Treeby and operates a large display village there; there is also a newer estate called Kara in the western part Established IN 2016, made a separate suburb from the portion of Banjup that extended north of Armadale Road; primarily a rural area originally; ~8.2km², ~4,214 pop; on the east side of the Kwinana Freeway close to Cockburn Central None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Treeby.
Recent work


What the work involves
- A written report you can act on. Photographs of each finding, what is urgent and what can wait and a price only for work that is genuinely needed. Including the finding that nothing is
- The roof surface, methodically. Ridge and hip capping for cracked bedding and perished pointing. Valleys, cleared enough to see the crease where rust starts. Flashings at every abutment, chimney, parapet and skylight. Every penetration, including anything added later for solar or air conditioning
- The drainage. Gutter falls, laps, internal corners and the fascia carrying them. Downpipes checked for flow and for where they actually discharge, because water dumped beside a footing is a problem of its own
Common questions about roof inspection in Treeby
Can you give a second opinion on another quote?
Yes and bring the quote. We will tell you where we agree with it, which is more often than people expect.
What if there is no manhole?
That is itself a finding, because it means nobody has ever assessed the roof space, including every previous owner and tradesman. Creating access is straightforward and worth doing.
Do you provide reports for insurers?
Yes. Photographs, identified damage and a written assessment that separates event damage from pre-existing wear, which is what gets a legitimate claim approved rather than argued.
How often should a roof be inspected?
Every few years for a roof in ordinary condition and after any severe storm. More often on older stock, coastal properties or anything with a history of leaks.
Do you work throughout Treeby?
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
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 Treeby roof that difference regularly amounts to thousands.
Getting a quote in Treeby
Call 0421 768 842 for an inspection. We photograph what is actually there, price the work that is genuinely required and tell you plainly when a Treeby roof needs less than you were expecting. That happens more often than people assume.
