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 Daglish.
Commercial roofing in Daglish: 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 Subiaco; more on our commercial roofing service page.
Why Daglish roofs behave the way they do
Daglish is unusual: an almost intact interwar garden suburb. The railway station opened in 1924, the Municipality of Subiaco bought the land west of it the following year to sell for housing. The subdivision was laid out on garden suburb principles, large lots, curved streets and generous green space. Most of the original homes are still standing, which gives the suburb significant heritage value as a whole streetscape rather than as a scatter of individual listings. That distinction matters: alteration here is constrained by the collective value of the street, so what is permitted should be checked before any change to the front of a house is planned. The construction is unusually well documented and each characteristic element has a known failure mode worth inspecting specifically: Rock-faced stone foundations, handsome. Every time. Built without a damp-proof course, so they draw moisture upward into the walls above. Hipped roofs clad in terracotta tiles, a century on, tiles become porous and brittle and are easily broken by anyone walking the roof. Wide boxed eaves with flat panels and timber battens, these conceal rot and give rodents and birds a way into the roof space. Daglish was built with a mixture of private and Workers Homes Board housing, so modest government-assisted homes sit beside private builds of the same era and quality varies within the streetscape. And because it was designed as a garden suburb, the mature trees are now large, working near century-old drainage and footings, with real limb loads over roofs.What that means for commercial roofing in Daglish
Wherever a Daglish 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 Shenton Park and Floreat, and a planned approach beats an emergency call-out over damaged stock.
Daglish 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 Daglish
Learn moreWhen a Daglish 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 Subiaco, 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 Daglish
Learn moreMost Daglish 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 Shenton 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 Daglish

Roof Restoration in Daglish
Learn moreA roof restoration renews a tired but sound Daglish 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 Floreat. 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 Daglish 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 Daglish

Roof Inspection in Daglish
Learn moreA roof inspection is the cheapest way to know exactly what your Daglish 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 Wembley, 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 Daglish

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

Structural Defect Repairs in Daglish
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 Daglish 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 Subiaco. 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 Daglish 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 Daglish premises — or a building you manage in nearby Wembley — 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 Daglish
Daglish is a rare thing: an INTACT 1925 GARDEN SUBURB where most original homes still stand, giving it significant heritage value as a whole streetscape rather than as scattered listings. That means alteration is constrained by the streetscape's collective value, not just individual listing, check what is permitted before planning any change to the front of a house.
The characteristic construction is well documented: ROCK-FACED STONE FOUNDATIONS, hipped roofs in TERRACOTTA TILES and WIDE BOXED EAVES with timber battens. Each has a known failure mode, stone foundations without a damp-proof course draw moisture upward, century-old terracotta tiles become porous. That matters. Brittle underfoot and boxed eaves conceal rot and give rodents and birds an entry point. Inspect them specifically rather than generically.
A mixture of private and Workers Homes Board housing, modest, standardised government-assisted homes alongside private builds, so quality and detail vary within the same era.
We cover the whole of the City of Subiaco. That takes in Subiaco and the streets around Daglish. 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 Daglish
Named after Henry Daglish, mayor of Subiaco and Premier of Western Australia 1904-05; Daglish Railway Station Opened IN 1924 in response to population growth in neighbouring Subiaco; THE Following Year the Municipality OF Subiaco Bought THE Land West OF THE Station TO Sell FOR Housing; development occurred over the following 20 years The suburb developed with a Mixture OF Private AND Workers Homes Board Housing during the mid-late inter-war period The initial development next to the railway station used Garden Suburb Principles, Large Lots. Gardens, Curved Streets and Lots OF Green Space; the suburb has Significant Heritage Value DUE TO ITS Uniform Streetscape, With Most Original Homes Still Standing; ~1,419 pop None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Daglish.
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 Daglish
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 Daglish and nearby?
Yes — across Daglish and neighbouring areas including Subiaco and Shenton Park. Ring 0421 768 842 and tell us about the building. We’ll inspect and scope it properly before quoting.
