Buying, selling, or simply have not looked in a decade. Those are the three reasons to have a Medina roof properly assessed and the third is the one that saves the most money.
Why Medina roofs behave the way they do
Medina was Kwinana's first suburb, designed in the early 1950s by Margaret Feilman, Perth's first female town planner, as the first of four “neighbourhood units” built to house workers for the new Kwinana Industrial Area. For an inspection, its single most important feature is the signature Medina house, whose original State Housing construction was highly specific: jarrah weatherboard to window height, asbestos sheeting above, on jarrah frames, floors and stumps. That fabric inspects nothing like the brick-and-tile found across most of Perth. Two things follow directly. First, a proper subfloor inspection is essential, those jarrah stumps and timber floors need checking for levelling, ventilation, moisture, borer and termite. Second, the asbestos sheeting is a defining part of the house, so careful asbestos assessment is central here, not incidental. It adds up. These are the two things a Medina report must get right. The suburb keeps its heritage Feilman “neighbourhood unit” layout, curved streets, mature street trees, some heritage-listed community buildings. Sits close to the Kwinana Industrial Area, so air quality, emissions and heavy-vehicle traffic are genuine local factors. Being near the coast and industry, salt is only a minor consideration (delignification low-to-moderate). The Medina report is really about its distinctive jarrah-and-asbestos fabric: the subfloor and the asbestos above it.Roof Inspection in Medina: the short version
The expensive problems live in the roof space, which is exactly the part nobody looks at. More on our inspection page.
What that means for roof inspection in Medina
Where a coastal roof has lost tiles in a front, the ones either side are usually loosened too, so an inspection after a storm covers the run rather than the gap.
The most useful finding on a character roof is frequently that the tiles are worth keeping and the structure beneath them is not, which is a very different job to a replacement.
The most valuable finding on these roofs is usually that the tiles are sound. A tired surface reads as a replacement candidate from the footpath and rarely is one.
Coastal properties warrant shorter inspection intervals than inland equivalents, particularly on the metalwork, which fails on its own schedule rather than the roof's.
Medina roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Roof looks tired from the street | Usually surface, not structure | Establish which before spending |
| 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 |
Guide only. Every roof differs, which is why we look before quoting.

Roof Repairs in Medina
Learn moreMost Medina 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 Orelia. 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 Medina
Learn moreA roof restoration renews a tired but sound Medina 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 Casuarina. 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 Medina 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 Replacement in Medina
Learn moreWhen a Medina 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 Kwinana Town Centre, 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 Medina

Roof Carpentry in Medina
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Medina 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 Kwinana Beach 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 Medina
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 Medina 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 Anketell. 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 Medina
Learn moreWhen a storm hits a Medina 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 Orelia. 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.

- 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
Local conditions in Medina
The signature Medina house: JARRAH WEATHERBOARD to window height + ASBESTOS SHEETING above, on JARRAH STUMPS with timber floors. This exact fabric demands: SUBFLOOR inspection (jarrah stumps/joists, levelling, borer, termite, ventilation, moisture) and careful ASBESTOS assessment (the sheeting is a defining feature). Inspects nothing like brick-and-tile.
Heritage 1950s Feilman 'neighbourhood unit' plan, curved streets, mature street trees; some heritage-listed community buildings; original layout intact.
Close to the Kwinana Industrial Area, air quality/emissions, heavy-vehicle traffic and industrial context a real local factor.
Near the coast/industry, salt a minor consideration; delignification low-moderate.
We cover the whole of the City of Kwinana. Around Medina that takes in Kwinana and Perth. Short drives keep roof inspection affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
An inspection is only as good as what it produces. You should receive photographs of each finding, a clear statement of what is urgent and what can wait and a price only for work that is genuinely required. A verbal account of a roof you cannot see is worth very little.
A little about Medina
Kwinana's First suburb; designed early-1950s by Margaret Feilman (Perth's first female town planner) as the first of four 'neighbourhood units' for workers in the new Kwinana Industrial Area; ~32km S of Perth; named after the ship Medina (1830); streets named for passengers/crew 1950s SHC neighbourhood-unit stock (jarrah/asbestos) + later infill; heritage town-planning layout; lower-income, established Built for the 1950s Kwinana industrial boom (BP oil refinery, BHP steel, Alcoa alumina, Csbp acid/superphosphate, Cockburn Cement), heavy-industry town None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Medina.

- 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
Common questions about roof inspection in Medina
How long does it take?
Around an hour on a typical single storey home. Longer on complex rooflines, older properties with a history of repairs, or where access is difficult.
Will you tell me if nothing is wrong?
Yes and it happens regularly. Roughly one in eight roofs we assess gets a recommendation other than the one the owner was expecting.
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.
Do you work throughout Medina?
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.
What to ask whoever quotes you
Ask what happens if the scope changes. On older Medina 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.
