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 Kenwick.
Commercial roofing in Kenwick: 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 East Cannington; more on our commercial roofing service page.
Why Kenwick roofs behave the way they do
Kenwick is three things at once: residential, light industrial and semi-rural, all within the one suburb. A large portion of it remains agricultural smallholdings of several acres, survivals from its time as one of the early farming communities of the Swan River Colony. That mix means what a property actually is varies enormously here, a conventional suburban house, a several-acre holding, or a dwelling backing onto industrial premises. So establishing the zoning and what surrounds the lot comes before anything else, because the inspection, the servicing and the neighbours all follow from it. It shows. On the acreage properties the whole property is the job: septic or aerobic systems, bore or tank water, dams, long driveways and farm outbuildings that are frequently old, unengineered and sometimes never approved. Kenwick also contains the Brixton Street Wetlands, which are of significant conservation value. Land adjoining protected wetlands carries real constraints on clearing and development and the ground nearby is typically low, with a seasonally high water table and poor drainage, conditions that a summer inspection will understate. The suburb is bounded by the Canning River to the south-west, bringing low ground. A flood context on the river flats and by the Roe and Albany Highways elsewhere, which carry substantial traffic and heavy vehicles past the western and northern edges.What that means for commercial roofing in Kenwick
Wherever a Kenwick 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 Queens Park and Wilson, and a planned approach beats an emergency call-out over damaged stock.
Kenwick 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 Kenwick
Learn moreWhen a Kenwick 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 East Cannington, 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.

Roof Repairs in Kenwick
Learn moreMost Kenwick 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 Queens Park. 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.

03Roof Restoration in Kenwick

Roof Restoration in Kenwick
Learn moreA roof restoration renews a tired but sound Kenwick 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 Wilson. 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 Kenwick 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.

04Roof Inspection in Kenwick

Roof Inspection in Kenwick
Learn moreA roof inspection is the cheapest way to know exactly what your Kenwick roof needs before you commit to anything — or before you buy. We get onto the roof and into the roof space, physically checking the tiles, pointing, valleys, flashings, gutters and the structural timber, then hand back a clear written report with photographs.
On older homes we test the timber for rot, termite damage and delignification; on newer ones we look for the builder-grade detailing faults that leak early. It’s the same thorough check we run through nearby Cannington, and it’s what tells you whether a roof needs a minor repair, a restoration or something structural. If you’re buying a home, an inspection of the one part most people skip — the roof space — is money very well spent, and the written report gives you something concrete to put in front of an agent, a buyer or your insurer rather than a verbal all-clear.

05Roof Carpentry in Kenwick

Roof Carpentry in Kenwick
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Kenwick 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 Wattle Grove 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.

06Structural Defect Repairs in Kenwick

Structural Defect Repairs in Kenwick
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 Kenwick 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 East Cannington. 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.

Signs a Kenwick 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 Kenwick premises — or a building you manage in nearby Cannington — 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 Kenwick
Kenwick holds RESIDENTIAL, LIGHT INDUSTRIAL and SEMI-RURAL land in the one suburb, so what a property actually is varies enormously, a suburban house, a several-acre smallholding, or a dwelling adjoining industrial premises. Establish the zoning and what surrounds a lot before anything else, because the inspection, the servicing and the neighbours all differ accordingly.
Much of the suburb is REMNANT AGRICULTURAL SMALLHOLDINGS of several acres. On those the property is the inspection: septic or aerobic systems, bore or tank water, dams, long driveways and farm outbuildings, often old, unengineered and sometimes unapproved.
The BRIXTON STREET WETLANDS are of significant conservation value. Land adjoining protected wetlands carries constraints on clearing and development and nearby ground is typically LOW with a seasonally high water table and poor drainage.
Canning River to the south-west (low ground, flood context on river flats) and Roe and Albany Highways on the other edges (traffic noise, heavy vehicles).
We cover the whole of the City of Gosnells. 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 Kenwick
Contains relatively Pristine Native Wetlands including the Brixton Street Wetlands, Which ARE OF Significant Conservation Value Bounded on the south-west by the Canning River and on the north-west by the ROE Highway; Albany Highway, the main south-east arterial, runs through the western part Contains several sites of historical significance relating to its status as ONE OF THE Early Farming Communities of the Swan River Colony, the Kenwick Pioneer Cemetery and Liddelow Homestead among them A Mixed Residential, Light Industrial AND Semi-Rural suburb; A Large Portion IS Remnant Agricultural Land Organised AS Smallholdings OF Several Acres; ~9.8km², ~5,684 pop None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Kenwick.
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 Kenwick
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 Kenwick and nearby?
Yes — across Kenwick and neighbouring areas including East Cannington and Queens Park. Ring 0421 768 842 and tell us about the building. We’ll inspect and scope it properly before quoting.
