Quick answer

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 Kensington roofs we treat first, wait for it to die, then clean properly.

Why Kensington roofs behave the way they do

Kensington has an origin that sets it apart from its neighbours: most of its early houses were weatherboard, not brick. That gave the suburb what contemporaries called a working-class image, strongly enough that a number of residents formally petitioned the Road Board to have Kensington declared “brick only&rdquo. For an inspector that history is directly useful, because timber-framed, timber-clad houses on stumps remain part of the local stock and they need a different examination from masonry. The priorities become subfloor condition, stumps, joists, ventilation, borer, along with the cladding and its junctions. One question worth asking specifically: whether brick veneer or render was later applied over an original timber frame, which changes how the wall behaves and how moisture moves through it. That matters. A second layer arrived in 1951, when a block bounded by George, Douglas, Oxford and Dyson Streets was granted to the State Housing Commission. That produced the Douglas/Moresby group, modest post-war housing of consistent design, now around seventy years old, carrying asbestos-era materials and services well past their working life. Two practical notes. Kensington straddles two councils, the City of South Perth and the Town of Victoria Park, so confirm which one holds the approval records for a given address. And Kensington Bushland forms a reserve edge, bringing termite pressure and habitat considerations to adjoining blocks.

Roof Cleaning in Kensington: the short version

A clean roof lasts longer and not for cosmetic reasons. Growth holds water against the surface indefinitely. Full detail on our roof cleaning page.

What that means for roof cleaning in Kensington

Concrete tile from this era is porous once the factory surface has gone, which is precisely what growth needs. A clean returns it to bare aged tile that begins weathering again immediately.

On strata properties roof cleaning is common property work, so it is scheduled through the owners corporation and done across the whole building rather than one dwelling at a time.

Debris sitting on a roof holds moisture against the surface for days after rain, which is what lets growth establish in the first place.

Roof Restoration in Kensington

A roof restoration renews a tired but sound Kensington 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 South Perth. 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 Kensington 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.

Most Kensington 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 East Perth. 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.

When a Kensington 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 Salter Point, 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 Inspection in Kensington

A roof inspection is the cheapest way to know exactly what your Kensington 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 Como, 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.

Roof Carpentry in Kensington

Roof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Kensington 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 Manning 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 Kensington

When a storm hits a Kensington 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 South Perth. 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 Kensington

Unusually for an inner suburb, most of Kensington's EARLY housing was WEATHERBOARD, not brick, so timber-framed, timber-clad homes on stumps are part of the local stock. Those need a different inspection from masonry: SUBFLOOR condition (stumps, joists, ventilation, borer), cladding and its junctions and the question of whether later brick veneer or render was applied over a timber frame. Residents of the day petitioned to have the suburb declared 'brick only', which tells you how much timber there was.

The Douglas/Moresby State Housing group dates from a 1951 grant to the State Housing Commission, modest post-war stock of consistent design, now around seventy years old, with asbestos-era materials and services well past their life.

The suburb straddles the City of South Perth and the Town of Victoria Park, confirm which council holds the approval records for a given address.

We cover the whole of the City of South Perth. Around Kensington that takes in South Perth and Victoria Park. Short drives keep roof cleaning affordable on smaller jobs and most of ours are smaller jobs.

Materials and specification

Cleaning is preparation as much as it is a service. If the roof is heading for a coating, the same clean feeds straight into sealing and applying the Dulux AcraTex system under accreditation. Doing them together costs less than doing them separately.

What the work involves

  • 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
  • Clear up afterwards. A clean produces a considerable quantity of debris that goes straight into your gutters and downpipes. Flushing them is part of the job rather than an extra

Common questions about roof cleaning in Kensington

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 Kensington?

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 to ask whoever quotes you

Three questions separate a genuine assessment from a sales visit and they apply to us as much as to anyone else. Which specific component has failed, rather than a general statement about age. Whether somebody entered the roof space, because batten condition cannot be judged from outside. And whether photographs exist. Clear answers to all three usually mean somebody looked properly.

Ring 0421 768 842. Somebody who has been on roofs will come and look at yours, photograph the findings and price the job itemised rather than by the square metre. Quotes on Kensington homes stay open for a reasonable period so nobody is rushed.
