Blasting a roof removes what you can see and leaves what matters. Lichen roots into the surface and grows back through anything applied over it. On Nollamara roofs we treat first, wait for it to die, then clean properly.
Roof Cleaning in Nollamara: the short version
Aged concrete tile is porous once its surface has gone, which is what lets growth take hold. Cleaning addresses the symptom and sealing addresses the cause. More on our cleaning page.
Why Nollamara roofs behave the way they do
Nollamara is the oldest of the “Mirrabooka Project” suburbs, the State Housing Commission developed it in the early 1950s and the name (the red-and-green kangaroo paw, WA's floral emblem) was approved in 1954. That makes the original stock around seventy years old and it changes the inspection in one important way: 1950s construction is squarely in the asbestos era. On the original houses, asbestos-containing materials, fibro sheeting, eaves linings, fencing, are genuinely likely and that is a health-and-cost consideration for any renovation or demolition, not a footnote. Old house one side, brand-new infill the other Nollamara is only about 8 km from the city, close enough now to be called “almost inner city” and that has driven subdivision and R-code infill. The result is a suburb where a 1950s State Housing house sits next to a brand-new duplex or triplex. Those are two completely different inspections: one about seventy-year-old fabric and asbestos, the other about the defects of brand-new construction. Establishing which you are buying is the whole starting point. It rarely is. Being inland and close-in, coastal salt and delignification are a low priority here. The Nollamara story is age, genuinely old stock, asbestos on the original houses and a suburb visibly rebuilding itself one subdivided block at a time.What that means for roof cleaning in Nollamara
Sea air keeps surfaces damp overnight even where rainfall is modest, which supports algae on elevations that would stay clean further inland.
Whole streets of this age develop the same pattern at the same time, so if neighbouring roofs are darkening yours is likely on the same schedule.
We assess metalwork while cleaning here, because deposit and corrosion tend to appear on the same roofs.
Coastal roofs collect more airborne deposit in sheltered areas that rain never reaches, under eaves, behind solar panels and wherever geometry creates a pocket. Those are the areas a quick wash misses.
Nollamara roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Roof clean but gutters full of grit | Surface breaking down | Assess whether coating is due |
| Dark vertical streaks | Algae, spreading with each rainfall | Treat and wash |
| Green cushions in the ridge joints | Moss holding water against mortar | Treat, clean, then re-point |
| Flat grey or sage crusty patches | Lichen bonded into the tile | Treat and wait, never blast |
Guide only. Every roof differs, which is why we look before quoting.

Roof Restoration in Nollamara
Learn moreA roof restoration renews a tired but sound Nollamara 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 Nollamara 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 Repairs in Nollamara
Learn moreMost Nollamara 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 Westminster. 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.

Roof Replacement in Nollamara
Learn moreWhen a Nollamara 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.

04Roof Inspection in Nollamara

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

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

Storm Damage Repair in Nollamara
Learn moreWhen a storm hits a Nollamara 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 Mirrabooka. 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.

Local conditions in Nollamara
The OLDEST of the Mirrabooka Project suburbs, early-1950s State Housing Commission stock. ~70 years old: original 1950s fabric, possible early asbestos-era materials, well past first service life.
Close-in location (~8km) driving subdivision/R-code infill, old SHC house on one block, brand-new duplex/triplex next door. Two inspections side by side.
1950s construction, asbestos-containing materials (fibro, eaves, fencing) genuinely likely on original stock.
Inland but close-in, salt/delignification low priority.
We cover the whole of the City of Stirling. Around Nollamara that takes in Balga and Mirrabooka. Short drives keep roof cleaning affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
Ask what product is being applied and how long it is left before washing. A contractor who cleans and leaves the same day has not treated anything. The waiting period is the work and it does not look like work, which is exactly why it gets skipped.
A little about Nollamara
1950s SHC origins through later infill; brick-and-tile; being redeveloped/subdivided in parts (R-coding infill) The Earliest of the 'Mirrabooka Project' suburbs, developed by the State Housing Commission in the early 1950s; name approved 1954 (Aboriginal for red-and-green kangaroo paw, WA floral emblem) None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Nollamara.
Recent work


What the work involves
- Identify what is actually growing. Algae streaks with the slope and is largely cosmetic. Moss holds water and roots in mortar joints. Lichen bonds chemically to the tile and resists physical removal entirely. They need different handling
- Treat, then wait. A biocide kills the organism including whatever is bonded into the surface. That takes days, not minutes and it is the stage that separates a lasting clean from a cosmetic one
- Clean at a pressure matched to the tile. Aged concrete that has been damp for decades has a softened surface. Excessive pressure removes material rather than dirt and drives water up under the laps into the roof space
Common questions about roof cleaning in Nollamara
Is it safe for my garden?
With proper protection and a thorough rinse down, yes. It is a fair question to ask any contractor before they start and isolating a rainwater tank is sensible.
Can I do it myself?
The chemistry is available. The height is the problem and mossy tile in the wet is genuinely treacherous. Ladder falls at home are common and serious.
Does cleaning fix leaks?
No. Cleaning is a surface operation. Leaks come from mortar, valleys and flashings and they should be traced separately.
Should I clean or coat?
If the surface is sound and only dirty, clean. If the tiles are porous and darkening after rain, cleaning alone returns you to bare aged tile that starts weathering again immediately.
What about the neighbour's roof?
Spores travel, so a heavily colonised roof next door contributes to yours continuously. You cannot control that, which is why your own conditions matter more.
Do you work throughout Nollamara?
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.
How to tell a real assessment from a sales visit
Ask what happens if the scope changes. On older Nollamara 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.
