A full replacement strips the covering and starts again, usually with new battens and sarking. It suits roofs where the tiles are breaking down or the framing has gone. For most Bentley properties something smaller does the job and we would rather quote that.
Roof Replacement in Bentley: the short version
Replacement is the largest job a roof can have and the one most often recommended when it is not needed. The honest question is which component has actually failed. Full detail sits on our roof replacement page.
Why Bentley roofs behave the way they do
Bentley is shaped by two forces that set it apart. The first is Curtin University, whose main campus and Technology Park sit in the suburb and drive a large student rental market. For an inspection that means a lot of investor and tenanted stock, with the patterns that come with it: deferred maintenance. Houses that have been informally converted or sub-divided for shared student living, worth checking that any such changes were done properly and approved. The second is its history as a public-housing suburb. The State Housing Commission developed Bentley from the 1940s, including war service homes for returning WWII veterans, some of which remain. So a good deal of the stock is modest post-war fabric, seventy to eighty years old, where asbestos-era materials are likely and services are well past their first life. The landmark Brownlie Towers public-housing flats were removed in 2019 and that precinct and others are being redeveloped into new medium-density infill, so newer strata now sits beside the old homes. Nothing dramatic. Being inland, coastal salt and delignification are a low priority in Bentley. The report here turns on which Bentley you are buying, an ageing war-service or Homeswest house, a student-rental conversion, or new infill and on the age and honesty of any alterations.What that means for roof replacement in Bentley
On the coast the decision is usually made by the battens rather than the tiles. Salt laden moisture works on timber over decades and once fixings will not hold across the roof, individual repairs stop working.
Roofs of this era were laid straight onto battens with no sarking at all. If the covering is coming off anyway, that is the moment to add it and to improve ventilation.
Committees need a documented scope with photographs. A verbal figure cannot be put to a vote, which is why the assessment matters as much as the price.
Bentley roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Asbestos sheeting, weathered | Regulated material | Licensed removal, then replace |
| Tiles slipping right across the roof | Battens failing generally | Re-batten and relay existing tiles |
| Faded chalky tiles, sound structure | Surface wear, not structural failure | Restoration, not replacement |
| Tile edges crumbling in the hand | Material genuinely at end of life | Replacement of the covering |
Guide only. Every roof differs, which is why we look before quoting.

Roof Restoration in Bentley
Learn moreA lot of Bentley's older homes and long-held rentals are well overdue for a restoration — years of deferred upkeep showing as dead colour and failing pointing over sound tiles. We kill the growth so it stays gone, set the ridges and cracked tiles right, then seal and coat the roof. For a fraction of a re-roof it lifts a tired home or rental noticeably, and protects the tiles from further neglect.

Roof Repairs in Bentley
Learn moreBentley is a real mix — older homes, a lot of rental and investment stock near the university, and pockets being redeveloped — and rentals in particular tend to carry deferred roof problems, because small leaks get put off. So repairs here are often a backlog: perished pointing, cracked tiles, a flashing that's been weeping a while. We sort the real source, match the tile, and re-point properly, rather than the quick patch a rental has usually already had.

Roof Carpentry in Bentley
Learn moreOn a Bentley rental or older home, a leak that's been left rather than fixed will often have reached the timber — a rafter or batten softened by water that dripped for a season or three. We cut back to sound wood, splice or replace to match, and shut off the leak at its source, turning years of deferred neglect into a proper, lasting repair rather than another patch.

Roof Inspection in Bentley
Learn moreBuying in Bentley often means an older home or a former rental, and rentals in particular hide deferred roof problems behind a quick tidy-up, so an inspection before you sign matters. We check the tiles, pointing, valleys and flashings and get into the cavity for the sarking and framing, then hand you a photographed report — so a property that's been patched to sell doesn't become your problem after settlement.

Storm Damage Repair in Bentley
Learn moreWhen a storm crosses the south-east, Bentley's tired and deferred-maintenance roofs are the ones that let go — the pointing that was already failing, the flashing nobody replaced. We get it watertight first so the ceilings stop taking water, then find where the wind actually got in and check the framing under any impact. Full documentation goes to the insurer if it's a claim, which on a rental matters.

Roof Tie-Downs in Bentley
Learn moreMuch of Bentley's older housing predates the tie-down rules, and years as rentals mean upgrades rarely happened. When we re-roof one we treat the hold-down as part of the job — following the connections from sheet to wall and bringing them up to current code — so a lighter new roof isn't relying on decades-old nails that no one's touched since the house was built.

Signs a Bentley roof may genuinely need replacing
- Fixings pulling out across the whole roof rather than in one spot
- Tiles breaking down at the edges rather than simply faded
- A roof line that has visibly sagged or wandered
- Sheeting perforated rather than chalky
- Repeated repairs that no longer hold
Local conditions in Bentley
1940s-50s State Housing Commission + WAR SERVICE HOMES, modest, older post-war fabric (~70-80 years); asbestos-era materials likely; ex-Homeswest construction patterns.
Curtin drives heavy student RENTAL/investor stock, deferred maintenance, converted/sub-divided houses, HMO-style wear; check for informal conversions.
Ex-Brownlie Towers precinct + public-housing renewal = new medium-density infill beside old stock; new strata.
We cover the whole of the City of Canning. Short drives keep roof replacement affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
If the covering is being replaced, exposure decides specification. BlueScope guidance for marine and industrial environments is explicit about grade, COLORBOND Ultra covers the heavier coated option and Lysaght supplies the profiles. Standard product in a harsh position is a warranty problem rather than a saving.
A little about Bentley
1940s-50s SHC + war-service homes + post-war + student rentals + new infill (ex-Brownlie Towers site redeveloping); lower-income, diverse Convict road-camp origins ('Bentley Hill' from 1860s, after warder John Bentley); 1880s dairy/piggery; WA's first drive-in theatre None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Bentley.
Recent work
What the work involves
- Flashings, penetrations and the edge. Every abutment, chimney, skylight, vent and solar mount is re-detailed and guttering is usually renewed while access exists because doing it later costs the setup twice
- Establish whether it is warranted. Roof space first, testing battens physically rather than looking at them. A tired surface on sound structure is a restoration, not a replacement and the difference is several multiples of cost
- Strip, assess and re-batten. The covering comes off, the framing beneath is inspected properly for the first time in decades and battens are replaced at the correct gauge for whatever is going back on
Common questions about roof replacement in Bentley
What about solar panels?
They come off and go back on, which needs coordinating with an electrical contractor. Raise it at quoting rather than discovering it mid job.
Can I change from tile to metal?
Yes and it reduces load on the structure. It also changes battens, detailing and rain noise and it costs more than relaying tile, so it is a choice rather than an economy.
How do I know a replacement quote is honest?
Ask three things. Which component has failed. Whether anyone entered the roof space. Whether photographs exist. Clear answers to all three usually mean the assessment was real.
Can I keep my existing tiles?
Usually yes. On most Perth roofs the tiles have decades left and it is the battens, fixings and missing sarking that have reached the end. Relaying is substantially cheaper than buying a roof's worth of tile.
Do you work throughout Bentley?
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.
Checking the quote before you sign
Ask what happens if the scope changes. On older Bentley 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.
