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 Hillarys.
Commercial roofing in Hillarys: 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 Kallaroo; more on our commercial roofing service page.
Why Hillarys roofs behave the way they do
Hillarys is essentially a 1970s-to-1990s suburb and that single fact sets the inspection. It barely existed before then, the namesake, Bertram Hillary, built a lone boatshed on the beach in 1930 and for years his family were the only residents and it was only gazetted in 1971. The building of Hillarys Boat Harbour in 1987 (for the America's Cup defence) drove the rest and the suburb was substantially complete by the mid-1990s. So the dominant stock is brick-and-tile from the 1970s, 80s and 90s and that housing is now thirty to fifty years old. Is exactly the age at which a first major maintenance cycle falls due. Roofs, ceilings, wiring, hot-water systems and the original wet-area waterproofing are all reaching the end of their first life at once. It is a very different set of findings from either a century-old Cottesloe house or a brand-new estate build: not decay from great age. It rarely is. Not the teething faults of new construction, but the predictable mid-life failures of a well-built suburb hitting middle age together. The ground here has its own signature. Unlike the flatter beach suburbs to the south, Hillarys keeps large sand dunes and remnant vegetation, the beach is famously hard to reach because of them. Elevated dune sites bring sand movement, retaining walls and down-slope drainage into the inspection. And it is a coastal, reef-fronted suburb (Marmion Marine Park lies offshore), so the sea air works on everything metal. In the older tiled roofs delignification is worth a look in the roof space, though much of Hillarys is young enough that it is a check rather than an expectation.What that means for commercial roofing in Hillarys
Coastal commercial roofs around Hillarys — strata blocks, retail and offices near the water — take the full salt load across large metal areas, so corrosion of sheeting, fixings and flashings is the main enemy. Specifying the right grade from the start is what makes the difference between a 10-year and a 25-year roof.
We re-sheet and re-flash in coastal grades, and set up maintenance so small corrosion issues are caught before they become a leak over stock or common property.
It’s the same commercial work we carry out through Craigie and Padbury, and a planned approach beats an emergency call-out over damaged stock.
Hillarys 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 Hillarys
Learn moreWhen a Hillarys roof has finally been beaten by the salt, we re-roof it for the conditions rather than the quote — coastal-grade Colorbond, corrosion-resistant fixings, and flashings detailed to shed wind-driven rain instead of funnel it in. We sort the sarking and framing while it's open, and mind how it's held down, because the wind off the water has a clear run at these roofs. The aim is a roof built to take the coast, which is exactly what it'll get.

Roof Repairs in Hillarys
Learn moreHillarys sits right on the northern coast by the boat harbour, and the salt air gets to the metalwork long before the tiles look tired — a valley rusted thin, a flashing lifted by the sea breeze, corroded fixings letting a ridge chatter loose. Most repairs here start there. We trace where the water's really getting in, replace the failed metal with coastal-grade material rather than the same thing that just rotted, and fasten it down against the wind coming off the water.

Roof Restoration in Hillarys
Learn moreA restoration this close to the coast has to fight salt from the first coat. We treat the growth the sea damp feeds, clean back to a sound surface, deal with the corrosion that's started on the metal, re-point what the wind's loosened, and finish in a coating rated for real coastal exposure. There's no point pretending a bargain job survives a Hillarys summer of onshore wind — spec it for where it sits and the finish lasts instead of chalking off in two seasons.

Roof Inspection in Hillarys
Learn moreA Hillarys roof can look fine from the street and be quietly corroding underneath from the salt, which is exactly why a pre-purchase inspection is worth it here. We get on top and into the roof space and look hard at the metal — valleys, flashings, fixings, the things the coast eats first — as well as the tiles and the timber, then give you a plain written report with photos, so you know whether you're buying a sound roof or a re-roof in disguise.

Roof Carpentry in Hillarys
Learn moreOn the Hillarys coast it's corrosion that opens the door — a salt-thinned valley weeps unnoticed and, over time, the rafter beneath it turns to sponge. These are the leaks nobody sees until the damage is done. We strip back to solid timber, splice or replace to match, and renew the corroded metal that caused it, because fixing the wood without fixing the valley just resets the clock on the same failure.

Structural Defect Repairs in Hillarys
Learn moreThe enemy on a Hillarys roof structure is corrosion as much as load — years of salt working into connections and framing where a coastal leak got a foothold. When an inspection turns up a genuine defect, we look past the obvious and check what the sea air has done to the fixings and the timber, then rectify and certify it as registered builders, so the structural side of the sale is genuinely resolved, not just cosmetically covered.

Signs a Hillarys 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 Hillarys premises — or a building you manage in nearby Connolly — 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 Hillarys
Overwhelmingly a 1970s-1990s suburb, that era's brick-and-tile and now its roofs/wiring/wet-areas at 30-50 years, coming due for their first major maintenance cycle.
Large sand dunes and remnant vegetation, elevated dune sites, sand movement, retaining and drainage.
Boat Harbour precinct, some higher-density/mixed use, marina-adjacent stock.
We cover the whole of the City of Joondalup. That takes in Cottesloe and the streets around Hillarys. 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 Hillarys
After Bertram John Hillary (1895-1957), who built a boatshed on the beach in 1930 during the Depression while fishing; for years the only residents; Army mapped it 'Hillary's Beach' in Wwii Predominantly 1970s-1990s housing; some newer infill Beach relatively hard to access due to large sand dunes and remnant vegetation (unlike suburbs further south) None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Hillarys.
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 Hillarys
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.
Our coastal building keeps rusting — what’s the fix?
Near Hillarys the salt load is high, so it comes down to grade — we re-sheet and re-flash in coastal grades and maintain it, rather than replacing cheap sheeting every few years.
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 Hillarys and nearby?
Yes — across Hillarys and neighbouring areas including Kallaroo and Craigie. Ring 0421 768 842 and tell us about the building. We’ll inspect and scope it properly before quoting.
