Roof Inspection
Most roof problems are cheap to fix early and expensive to ignore. Our detailed inspection checks tiles, pointing, valleys, flashings, gutters and the timber below — with photos of everything, not a vague verbal all-clear. Ideal before buying a home, after a storm, or when a stain appears and you need to know how bad it really is.

An inspection that skips the roof space is not an inspection. Powerdrive walks the roof, checks the ridge, valleys, flashings and penetrations, then gets underneath where a manhole allows and tests the timber. You get photographs and a written assessment for your Perth property, free of charge.
Roof Inspection across Perth
A quote is not an assessment. One tells you a price, the other tells you what your roof is doing.
The expensive problems live in the roof space, which is exactly the part nobody looks at.
What the work involves
- 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
- The roof space, where access allows. Battens and rafters tested physically rather than looked at. Sarking, if any was ever installed. Staining on timber that shows where water has travelled and insulation that has been wet
- 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
When a your roof is worth having inspected
- You are buying and the building report mentioned the roof
- You are selling and want to know what an inspector will find
- 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
Match the symptom to the 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 |
| No manhole in the house | Roof space never examined by anyone | Access created, then assessed |
| Storm damage to document | Claim needs evidence | Photographic assessment for the insurer |
| Roof looks tired from the street | Usually surface, not structure | Establish which before spending |
Guide only. Every roof is different, which is why we look before quoting.
How roof inspection differs across Perth
What a roof inspection needs to look for — salt corrosion, damp, movement, hidden timber or storm damage — changes with where the home sits. Here is how it plays out across Perth, and why what matters is what you can’t see from the ground.
On the coast
On the coast a roof inspection has to look closely at the metalwork, because salt corrosion hides in the flashings, valleys and fixings — the parts that fail first — rather than showing on the tiles. Along the coastal strip through Scarborough, Hillarys and Sorrento a roof can look fine from the street while the valleys are rusting through at the crease.
We get onto the roof and into the roof space and physically check the valleys, flashings and fixings for the corrosion salt causes, rather than assessing from the ground. On the coast that close look is the whole value — the failures are hidden at the joints and creases, so a proper inspection means testing the metalwork and the timber it protects, photographing what we find, and giving you a clear picture of what’s sound and what’s quietly corroding before it becomes a leak.
The corrosion a coastal inspection catches is exactly what a street-level look misses, on homes around Cottesloe. Our guide to signs your roof needs attention before winter covers what to watch for.
In the river suburbs
In the shaded river suburbs, moss and damp hide problems a ground-level look never catches — growth conceals cracked tiles, and the damp planes hide the early rot a slow leak has started. Through Melville, Applecross and Bicton those hidden issues under the growth are what an inspection is really for.
We clear enough to see properly, check the shaded planes and valleys where growth clusters, and get into the roof space to check the timber a leak may already be softening. On these roofs the inspection has to go beneath the surface — a cracked tile hidden under moss or a damp rafter above the ceiling won’t show from the ground — so we look where the problems actually hide and document them with photos, giving you findings you can act on rather than a reassuring glance.
The issues on a river-suburb roof hide under the growth and above the ceiling, on homes around Bassendean. Our guide to signs your roof needs attention covers the early warnings.
Up in the hills
Up in the hills the usual finds are blocked valleys and dislodged caps under the canopy, plus the loading and access issues that come with older, split-level roofs. Around Kalamunda, Lesmurdie and Roleystone that’s the pattern a hills inspection turns up.
We check the valleys for debris damming, the ridge and hip caps for movement, and the roof space for any water the blocked drainage has let in, across every plane of a complex roofline. On a hills roof there’s simply more to inspect — more valleys, more junctions, more exposure — so we work methodically across the whole roof and photograph the findings, because on a split-level home under heavy trees the problems are spread out and easy to miss with a quick look.
A yearly check genuinely pays off under a hills canopy, on homes around Mundaring. Our guide to a simple yearly maintenance checklist helps you stay ahead of it.
On low, damp ground
On low, damp ground the damp roof spaces hide soft timber that only a proper check finds — the persistent humidity softens framing quietly, and it won’t show from below until it’s well advanced. In the lower-lying pockets around Bayswater, Bassendean and Ascot that hidden softening is the key thing to catch.
We get into the roof space and physically test the timber rather than eyeballing it, because degraded and delignified timber frequently looks perfectly normal until it’s pushed. On damp ground that physical testing is the crucial part of the inspection — a rafter can look sound and crumble at a screwdriver — so we check the framing properly, distinguish decay from delignification, and give you a clear, photographed picture of the structure hiding above the ceiling.
Soft timber only a proper check finds is exactly the risk here, on homes around Maylands. Our guide to why to check the timbers first explains why the roof space is the part people skip.
On reactive clay
On reactive clay the seasonal movement cracks pointing and tiles, and an inspection maps out that cracking and distinguishes it from a genuine structural fault — which matters, because recurring cracks worry owners more than they sometimes should. Through the clay belt around Gosnells, Forrestfield and Thornlie that’s a common reason for a check.
We map the cracked pointing and tiles, check whether the movement has stressed the frame, and set out clearly what’s cosmetic seasonal cracking and what needs proper rectification. On reactive ground the value is the judgement — not all cracking is a crisis, but some of it is — so we assess it properly and photograph it, giving you an honest read on whether you’re looking at routine re-pointing or something that needs a structural response, rather than either panic or false reassurance.
Telling seasonal cracking from a defect is the useful part here, on homes around Maddington. Our guide to signs your roof needs attention covers what’s worth acting on.
On the sand plain
Across the free-draining sand plain the newer roofs often hide builder-grade detailing faults worth catching early — a flashing that never sealed or a valley under-detailed from new — rather than age-related wear. Through Wanneroo, Baldivis and Butler those original-workmanship issues are the common find.
We check the flashings, valleys and tile-laying for the detailing faults that show up on newer roofs, and flag anything that may sit under the builder’s warranty. On newer stock the inspection is often about catching an original fault before it leaks — and before the warranty runs out — so we look hard at the detailing rather than the wear, document what we find, and tell you whether it’s a fault to claim or simply something to keep an eye on.
Catching a fault early, while it may still be the builder’s cost, is the value here, on estates around Ellenbrook. Our guide to how to choose a roofer and avoid the dodgy ones is worth a read.
On character and heritage homes
On character and heritage homes, old timber and delignification are exactly what a heritage-home inspection checks — the framing is old enough for the lignin breakdown that leaves it sound to the eye but weak in fact, alongside old cuts and additions. Through Fremantle, Guildford and Mount Lawley that timber condition is the priority.
We get into the roof space and physically test the timber, distinguishing delignification from rot and termite damage, because on an old frame they look identical from below but each means a different fix. That diagnosis is the heart of a heritage inspection — whether the timber can be treated in place or needs replacing changes the whole scope and cost — so we test rather than assume and give you a clear, photographed picture of what the roof is actually carrying.
Getting the timber diagnosis right is essential on old framing, on homes around Subiaco. Our guide to why to check the timbers first explains why it matters before you buy.
On post-war housing
On post-war housing the original timber and any old fibre-cement are worth a close look, and this era’s framing is a prime delignification candidate — so an inspection here is as much about the roof space as the covering. Across the post-war suburbs of Morley, Dianella and Bentley that’s the standard focus.
We test the timber condition, check the pointing and valleys, and identify any material that needs careful handling before anyone cuts or drills. On this stock the inspection often decides between a manageable treatment and a bigger job — delignified battens caught in time are treatable, caught late they’re a re-roof — so we check properly and photograph it, giving you a clear read on whether the roof is a tidy maintenance case or something that needs more, rather than a guess from the ground.
The timber assessment is the key on post-war stock, on homes around Nollamara. Our guide to why to check the timbers first covers what a proper check involves.
On newer estates
On newer estates a fault found early may still sit under the builder’s warranty, so an inspection is often about catching original detailing issues before both the leak and the warranty run out. Through Joondalup, Aveley and Harrisdale that timing is the value.
We check the flashings, valleys and tile-laying for original faults, and any truss members that may have been cut for later fixtures, then set out clearly what’s warranty and what isn’t. On a young roof the inspection is preventative and financial as much as anything — finding a detailing fault now, while it’s still the builder’s responsibility, saves you the repair — so we document it precisely and tell you exactly where you stand before anything gets worse or any deadline passes.
Knowing what’s warranty before it lapses is the point here, on estates around Byford. Our guide to how to choose a roofer helps you pick who does the work.
On strata and multi-residential
On strata and multi-residential, a documented inspection with photos is what the owners corporation needs — a committee has to minute decisions and justify spending, so a verbal all-clear is no use to them. Around Victoria Park, Rivervale and Burswood that documentation is the whole requirement.
We inspect the full shared roof — tiles, pointing, valleys, flashings, gutters and the timber — and hand back a clear, fully photographed report the committee can act on. On a multi-unit building the report is the deliverable as much as the inspection — it has to be clear enough to minute, detailed enough to prioritise, and photographed enough to justify — so we document everything methodically and write it in plain language rather than jargon, giving the committee something they can genuinely use.
A documented, photographed report is exactly what strata management needs, on buildings around East Perth. Our guide to a simple yearly maintenance checklist covers what regular checks catch.
Near heavy industry
Near heavy industry, exposure corrodes the metalwork an inspection needs to assess in full, and combined with damp it can drive decay in the timber too — so the check has to cover both across the whole roof. Around Kwinana, Welshpool and Bibra Lake that combined exposure is the focus.
We assess all the metalwork rather than just the obvious failure, test the timber, and distinguish corrosion, rot and delignification where they turn up together. In an industrial exposure the inspection has to be thorough, because the deterioration is spread and mixed — corroded connectors, damp-driven decay and delignified timber can all be present at once — so we test rather than assume and photograph the findings, giving you an accurate picture rather than a partial one that misses half the problem.
Assessing the whole roof matters where corrosion is widespread, on sites around Naval Base. Our guide to signs your roof needs attention covers the warning signs.
In bushfire areas
In bushfire areas, ember gaps at flashings and litter in the valleys are key inspection points — the check has a fire-safety dimension up here on top of the usual weather one. Through the bushfire hills of Kalamunda, Mundaring and Roleystone that dual focus shapes the inspection.
We check the flashings and penetrations for the gaps embers exploit, the valleys and gutters for the dry litter that’s an ignition risk, and the roof generally for weather-tightness. Up here the inspection does double duty — the same gaps and debris that let water in also raise the fire risk — so we look at the roof through both lenses and photograph what we find, giving you a report that covers both keeping the rain out and reducing the ember risk before summer.
The fire-safety angle makes a pre-summer check genuinely worthwhile here, on homes around Bedfordale. Our guide to a simple yearly maintenance checklist helps you plan it.
Under mature trees
Under mature trees, hidden limb strikes and debris damage sit under the tiles, out of sight, and the constant damp feeds decay — so an inspection here is about finding what the canopy has quietly done above the ceiling. Through the leafy streets of Nedlands, Applecross and Mount Lawley that hidden damage is the focus.
We check the field and valleys for impact damage, get into the roof space for the timber a strike may have cracked or the damp may have softened, and look beyond the one obvious problem. Under heavy canopy the inspection has to go beneath the surface — limb damage rarely stops at the visible break and the damp works quietly — so we assess the surrounding structure and photograph it, giving you the full picture rather than the reassuring bit you can see from the ground.
The damage a tree-shaded roof hides is exactly what a proper check finds, on homes around Dalkeith. Our guide to how to spot damage you can’t see from the ground covers it.
On exposed, elevated blocks
On exposed, elevated blocks, wind damage to flashings and cappings is the usual find — the exposure lifts and works the ridge and the terminations far more than on a sheltered site. Around the high, open blocks near Kalamunda, Gooseberry Hill and higher Hillarys that wind damage is the pattern.
We check the ridge and hip caps for movement, the flashing terminations for wind-driven damage, and the tie-down and fixings that the exposure works hardest. On a high block the inspection focuses on what the wind attacks — the caps, the terminations, the connections — so we assess those closely and photograph them, and where the tie-down looks marginal for the exposure we’ll flag it, because on an exposed roof the fixing matters as much as the covering.
Wind damage to the caps and terminations is the usual find up here, on homes around Darlington. Our guide to how to spot damage you can’t see from the ground covers what to look for after a blow.
On made ground
On made ground, settlement opens junctions that an inspection traces before they leak — the slow, uneven movement stresses the frame and the flashings, and the early signs are subtle. On the made-ground pockets around Rockingham, Baldivis and Wellard that settlement-driven movement is the thing to catch.
We check the wall junctions, ridge and flashings for the early opening that settlement causes, and the frame for any stress the movement has put on it. On settling ground the value is catching the junctions before they leak — the movement is gradual, so an inspection can spot the early separation and let you address it before it becomes a leak and soaks the timber — and we photograph and explain it clearly so you know what’s moving and what to keep an eye on.
Tracing the junctions before they leak is the useful part on made ground, on homes around Byford. Our guide to why the stain is never where the leak is covers tracing a leak once one starts.
Common questions
Do you charge for an inspection?
No. The inspection, the photographs and the written quote cost nothing, including when the outcome is that your roof needs very little.
What makes an inspection thorough?
Entering the roof space and testing timber physically rather than glancing from the manhole. Anyone who has not been underneath has looked at your roof rather than inspected it.
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.
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.
Is it useful before buying?
Very. Defects found before settlement are negotiating positions. Defects found afterwards are your problem entirely.
