Fully licensed & accredited — Builders Registration BC105819 · Painters Registration PC102072 · Patent ID AU-A-2020100623
Commercial roofing covers the larger, higher-stakes roofs — factories, warehouses, strata, retail and offices — where a leak means downtime, stock damage or a strata levy, not just a stained ceiling. We re-roof metal deck, install and repair membrane, and run scheduled maintenance, all planned around an operating business, and backed by a proper roof inspection and report. As WA-registered builders we can also handle structural work and certify it. Free inspection, written quote, 10-year workmanship warranty. Serving Bentley.
Commercial roofing in Bentley: the short version
A commercial roof is a business asset, and a failure on one is measured in downtime and damaged stock as much as repair cost. The work is the same disciplines as residential — done at scale, to spec, and scheduled so it doesn’t stop the business underneath it. We do the same through nearby Joondalup; more on our commercial roofing service 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 commercial roofing in Bentley
Wherever a Bentley commercial building sits, the roof is a business asset, and the failures that matter are the ones that stop trade — box gutters, membrane, flashings and large metal areas. The work is scaled up and scheduled around the business.
We re-roof, waterproof and maintain, with proper access and safety, so the roof does its job without becoming an operational problem.
It’s the same commercial work we carry out through Fremantle and Rockingham, and a planned approach beats an emergency call-out over damaged stock.
Bentley commercial roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Water over stock or a tenancy | Box gutter or membrane failure | Assess and renew the detail |
| Rust across large sheeted areas | Sheeting/fixings corroded | Re-sheet in correct grade |
| Ponding on a flat section | Fall or membrane failing | Re-waterproof, correct fall |
| Leaks around skylights/penetrations | Flashing or surround failed | Re-flash or replace |

Roof Replacement in Bentley
Learn moreWhen a Bentley roof is genuinely spent — often one that's been patched rather than maintained for years — we replace it and put right what the deferred upkeep let slide: fresh sarking, sound framing, and properly detailed flashings and valleys, with a straight steer on tile versus lighter Colorbond. Whether it's an owner-occupier or an investment property, the aim is a roof that's done once and stops the recurring call-outs.

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 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 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.

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.

Structural Defect Repairs in Bentley
Learn moreBentley's older and long-rented homes turn up structural history that deferred upkeep has let worsen — a crept rafter, a dropped ridge, timber weakened where a leak ran unchecked for years. When an inspection names a genuine fault, we diagnose what's really going on, involve an engineer where warranted, and certify the rectification as registered builders, so a sale clears rather than stalling on the report.

Signs a Bentley commercial roof needs work
- Water appearing over stock, machinery or a tenancy after rain
- Widespread rust, ponding or debris in box gutters visible from access
- Recurring leaks around skylights, penetrations or parapet flashings
If that’s your Bentley premises — or a building you manage in nearby Midland — a planned assessment beats downtime. It’s worth knowing the realistic life of a roof and reading the signs a roof needs attention.
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.
Specification, access and compliance
On a commercial roof the grade of sheeting, the box-gutter sizing and the membrane system are what determine whether it lasts, so we specify to the exposure and the use, using Lysaght and manufacturer systems, with proper height access and safe-work method on site.
As WA-registered builders (BC105819) we can also certify structural work on the roof, which a sheeting-only contractor can’t — and comparing scopes not just prices matters even more on a large asset where a cheap job fails expensively.
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.
What the work involves
- Assess the asset. A proper inspection of sheeting, box gutters, membrane, flashings and penetrations, with a written report and scope — no guesswork on a large roof.
- Metal deck & membrane. Re-sheeting in the correct grade, membrane and waterproofing on flat sections, box-gutter upgrades and skylight replacement.
- Structural where needed. As registered builders we can address and certify structural issues — purlins, bracing and framing — that a sheeting contractor can’t.
- Planned around the business. Staged works, out-of-hours where needed, proper height access and safety, and scheduled maintenance so the roof is managed, not just repaired when it fails.
Common questions about commercial roofing in Bentley
Can you work around our operating business?
Yes — that’s standard on commercial jobs. We stage the work, do noisy or disruptive stages out of hours where needed, and keep the site safe and access controlled so trade continues underneath.
Do you handle box gutters and membrane, not just sheeting?
Yes — box gutters, membrane and waterproofing on flat sections, skylights, penetrations and flashings are the details that actually cause most commercial leaks, and we repair or renew all of them.
Can you certify structural work on a commercial roof?
Yes — as WA-registered builders we can address and certify structural issues like purlins, bracing and framing, which a sheeting-only contractor can’t sign off.
Do you offer scheduled maintenance?
Yes — on a large roof, scheduled maintenance catches small issues before they become leaks over stock. It’s far cheaper than an emergency call-out and the damage that comes with it.
Do you do commercial roofing throughout Bentley and nearby?
Yes — across Bentley and neighbouring areas including Joondalup and Fremantle. Ring 0421 768 842 and tell us about the building. We’ll inspect and scope it properly before quoting.
