If somebody has quoted you a new roof for a leak, get a second opinion. Most Westminster roofs we attend need one component addressed and the tiles above it have decades left.
Roof Repairs in Westminster: the short version
A repair is targeted work on a specific fault. That is a different job to a restoration and it should be priced differently. Full detail sits on our roof repairs page.
Why Westminster roofs behave the way they do
Westminster is another of the State Housing Commission “Mirrabooka Project” suburbs, developed, with Balga and Nollamara, from the late 1950s and 1960s. That places it among the older post-war public-housing suburbs, so the original stock is single-storey brick-and-tile built to the Homeswest patterns of the day, now around sixty years old, with services well into their second life. On the earliest houses, asbestos-era materials are a genuine possibility to check before any renovation. As an affordable suburb with a significant rental and social-housing share, Westminster shows the usual signs of the type: deferred maintenance on tenanted houses. Decades of informal additions and renovations that a report needs to trace and assess. Predictably so. Its close-in position (about 9 km from the city) is also driving subdivision and infill. A sixty-year- old State Housing house may sit next to a brand-new duplex, two different inspections on adjoining blocks. Being inland, the coastal salt problems, delignification among them, are a low priority in Westminster. The inspection here is about 1950s-60s construction, the state of ageing services, asbestos on the oldest stock and the history of what has been altered.What that means for roof repairs in Westminster
Salt does not attack tile. It attacks everything holding the tile down. That is why a coastal roof can look immaculate from the driveway while its fixings and valleys are finished and why the inspection matters more here than the quote.
Roofs bedded in the same cement across a whole street in the same year tend to fail together, so if yours has gone your neighbours probably have too.
Near heavy industry we assess metalwork generally rather than only at the point of failure. Corrosion in this environment rarely confines itself to one component.
Where one length of valley has perforated, the rest of that run is the same metal at the same age in the same salt. We will say when a patch is honest and when it is buying a season.
The useful thing about this stock is predictability. We know what we will find before the ladder goes up, which makes diagnosis quick and keeps repair costs contained.
Westminster roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Same tile slips repeatedly | Batten below no longer holds a fixing | Replace batten, then refix |
| Leak near a vent or solar mount | Penetration never detailed properly | Re-detail the penetration |
| Previous repair failed within a season | Sealant over an unresolved defect | Remove and repair properly |
| Leak only in wind-driven rain | Water entering at the ridge line | Re-bed and flexible re-point |
Guide only. Every roof differs, which is why we look before quoting.

Roof Restoration in Westminster
Learn moreA roof restoration renews a tired but sound Westminster 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 Mirrabooka. 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 Westminster 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.

Roof Replacement in Westminster
Learn moreWhen a Westminster 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 Balga, 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.

03Roof Inspection in Westminster

Roof Inspection in Westminster
Learn moreA roof inspection is the cheapest way to know exactly what your Westminster 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 Nollamara, 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.

04Roof Carpentry in Westminster

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

05Storm Damage Repair in Westminster

Storm Damage Repair in Westminster
Learn moreWhen a storm hits a Westminster roof — lifting ridge caps, cracking tiles or dropping a limb through it — our first job is always to make the roof safe: tarp the opening, stop the water, and take the immediate danger out of it. Only then do we scope the permanent repair and deal with your insurer.
We document the damage thoroughly, separating genuine storm damage from pre-existing wear so the claim is properly supported, and we check the framing around any impact because a limb strike shock-loads more than the visible hole. It’s the same rapid response we bring to nearby Koondoola. Getting there quickly limits the internal damage — an hour of water ingress can mean ceilings and insulation you’ll otherwise be replacing later. We liaise with your insurer directly and hand back a documented, photographed scope, so the claim is straightforward and the repair holds up in the next blow rather than becoming the next emergency.

06Roof Cleaning in Westminster

Roof Cleaning in Westminster
Learn moreRoof cleaning strips the moss, lichen and black weathering off a Westminster roof and gets it back to a clean, even surface — either as a standalone tidy-up or as the first stage of a restoration. We treat the growth first so it dies at the root, then clean at a pressure matched to the tile so we lift the grime without stripping the surface or driving water under the laps.
Left alone, that growth holds moisture against the tiles and works into the pointing, which is why we treat rather than just blast it — the same method we use through nearby Mirrabooka. We check the roof over while we’re up there and flag anything that needs attention, so a clean doesn’t paper over a repair that’s quietly getting worse. On steeper or two-storey Westminster roofs we work off proper anchorage and stay off the tiles where we can, so the clean lifts the grime without cracking the very surface it’s meant to protect, and we’ll let you know if the roof would be better served by a full restoration.

Local conditions in Westminster
State Housing Commission stock, late-1950s-60s, old post-war public-housing fabric, ~60 years, ex-Homeswest patterns, asbestos-era materials possible on the earliest.
High rental/social-housing share, deferred maintenance, informal additions.
Close-in + affordable = subdivision/infill pressure; old SHC house beside new duplex.
Inland, salt/delignification low priority.
We cover the whole of the City of Stirling. Around Westminster that takes in Balga and Nollamara. Short drives keep roof repairs affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
Repairs are only as good as what goes into them. Pointing uses a flexible compound rather than sand and cement, because rigid mortar is what failed originally. Replacement tiles are matched through Bristile Roofing or salvage stock at Roof Top Industries, so a patch does not announce itself from the footpath.
A little about Westminster
One of the 'Mirrabooka Project' State Housing Commission suburbs (with Balga & Nollamara); developed from the late 1950s-1960s SHC-era single-detached brick-and-tile; some grouped dwellings/flats; affordable; ~9km N of CBD None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Westminster.
Recent work


What the work involves
- Tell you what else we saw. Including the parts that are fine. You get photographs and a written price for the work that is genuinely required rather than a package
- Find the actual fault. The roof gets walked, the ridge and valleys checked and the roof space inspected where a manhole allows. Water travels along battens before it drops, so the stain is rarely under the problem
Common questions about roof repairs in Westminster
Do you use roof cement?
Not as a repair. It cracks, traps water against neighbouring tiles and makes the eventual proper fix harder. Where we find it, it comes out.
Is it worth repairing an older roof?
Frequently yes. Tiles outlast the mortar and metalwork around them, so an old roof is often sound underneath a tired surface.
Do you guarantee the work?
Ten year workmanship warranty in writing. Where a coating is involved the manufacturer warranty is separate and comes through accreditation, so you finish holding two documents covering different failures.
Can you attend at short notice?
For active leaks, yes. Booked repairs run on a schedule and we will give you a realistic date rather than an optimistic one.
What if the leak returns?
Ring us. A repair that fails inside the warranty is our problem to sort out and we would rather hear about it than have you assume that is normal.
Do you work on commercial buildings?
Yes, including strata. Those need a documented scope with photographs rather than a verbal figure, because a committee has to act on it.
Do you work throughout Westminster?
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.
What we look at first in Westminster
Every Westminster roof gets the same opening assessment regardless of what you rang about. Ridge and hip capping for cracked bedding and perished pointing. Valleys, cleared enough to see the crease where rust starts. Flashings at every abutment, chimney and skylight. Penetrations, including anything a solar installer added later. Gutter Replacement Perth, laps and the fascia carrying them. Then the roof space if the manhole allows it, looking at battens, sarking and any staining on the timber that shows where water has been travelling. It takes about an hour and it is what separates a quote from a guess.
How to tell a real assessment from a sales visit
Ask what happens if the scope changes. On older Westminster 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.
