Quick answer

Concrete driveways, paving and masonry take high pressure well. Aged roof tiles, old render and soft timber do not. Knowing which is which is the whole job and on a Shelley home it is the difference between a clean surface and a damaged one.

Why Shelley roofs behave the way they do

Shelley has a ground history that every inspection here has to start with: much of the suburb is land reclaimed from the Canning River. It is avoidable. In a 1960 reclamation scheme, the Shire filled about a mile and a half of foreshore swamp to create eighty river-frontage lots and the Shelley Foreshore Reserve. That means large parts of Shelley, especially the sought-after riverside blocks, sit on made ground over former swamp. Made ground carries real risks: settlement, a high and sometimes variable water table and footing or slab movement as fill consolidates over decades. On the reclaimed foreshore lots, this is the single most important thing to understand. The Canning River frontage compounds it: the low riverside blocks carry a high water table, a flood context and subfloor damp, over reactive clay and organic ground beneath the fill. So drainage and how a home has coped with wet, settling ground, are central to a Shelley report. As a desirable riverside suburb, Shelley also sees knock-down-rebuild, so original 1960s homes sit beside new two-storey builds, two different inspections. On the new ones it is worth checking how the foundations were engineered for the reclaimed ground. Being a river suburb rather than a coastal one, salt-driven delignification is a low priority; in Shelley it is reclaimed land and the river that shape everything.

Pressure Cleaning in Shelley: the short version

High pressure suits hard, sound, non porous surfaces. It is wrong for aged tile, brittle terracotta, soft render and anything containing asbestos. More on our pressure cleaning page.

What that means for pressure cleaning in Shelley

Damp conditions in these streets mean paths, paving and retaining walls grow algae rather than simply collecting dirt. Treating the growth first means far less pressure is needed to remove it.

Large volumes of water against a house on reactive clay is worth avoiding, since concentrated wetting near the footings contributes to the seasonal movement that cracks buildings.

Runoff has nowhere to drain on saturated ground, so managing where several hundred litres ends up is a real consideration rather than an afterthought.

Roof cleaning strips the moss, lichen and black weathering off a Shelley 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 Ferndale. 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 Shelley 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.

Roof Restoration in Shelley

A roof restoration renews a tired but sound Shelley 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 Riverton. 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 Shelley 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 Shelley 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 Rossmoyne. 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 Shelley

When a Shelley 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 Langford, 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 Shelley

A roof inspection is the cheapest way to know exactly what your Shelley 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 Lynwood, 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 Shelley, Perth

Roof Carpentry in Shelley

Learn more

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

  • Retaining walls and steps with moss on the shaded side
  • A patio or alfresco that has stopped looking maintained

Local conditions in Shelley

Much of Shelley is RECLAIMED/FILLED former river swamp (1960). Made ground over old swamp = settlement risk, a high (and possibly variable) water table and slab/footing movement. On the reclaimed foreshore lots this is THE inspection issue.

Canning River frontage, high water table, flood context, subfloor damp; reactive clay/organic ground beneath fill.

Desirable riverside land value drives knock-down-rebuild, original 60s homes beside new two-storey builds; establish which + rebuild quality.

We cover the whole of the City of Canning. Around Shelley that takes in Riverton and Rossmoyne. Short drives keep pressure cleaning affordable on smaller jobs and most of ours are smaller jobs.

Materials and specification

Where cleaning is preparation for a roof coating, the sequence matters more than the equipment. Treat growth, wait for it to die, clean at a pressure suited to the tile, then seal and apply the Dulux AcraTex system under accreditation. Cleaning alone returns a roof to bare aged tile that starts weathering again immediately.

A little about Shelley

Much OF Shelley IS Land Reclaimed From THE Canning River, 1960 Shire of Canning reclamation scheme: filled 1.5 miles of foreshore swamp between Corbel St & Beatrice Ave, resumed 36 acres, created 80 river-frontage lots (Zenith St-Fifth Ave) + Shelley Foreshore Reserve 1960s-onward + modern rebuilds; river-frontage prestige homes Named for shells found on the Canning River shore; part of Riverton until mid-1960s None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Shelley.

What the work involves

  • Work down, never uphill under laps. On any roof or overlapping surface, driving water uphill forces it behind and underneath. That damage is invisible on the day and appears as a stained ceiling weeks later
  • Protect surrounds and manage the runoff. Plants covered, windows and fittings protected and the considerable volume of dirty water directed somewhere sensible rather than into a soakwell it will block
  • Identify the surface before anything else. Concrete, brick, limestone, render, timber, coated steel and aged roof tile all behave differently under pressure. Asbestos cement is identified and left alone, because cleaning it releases fibres

Common questions about pressure cleaning in Shelley

Where does all the water go?

Into your drainage, carrying whatever came off the surface. On a large job that is a genuine volume and it can silt a soakwell. Managing the runoff is part of doing it properly.

Is soft washing better?

On fragile surfaces, considerably. It applies treatment chemistry at low pressure and lets it work over time, then rinses gently. It takes longer and it does not damage what it is cleaning.

Can you clean before painting?

Yes and preparation is exactly where pressure cleaning earns its place. Coatings adhere to the substrate, not to what is sitting on it.

Can I hire a machine and do it myself?

For a concrete driveway, yes, with a fan tip and sensible distance. For anything on a roof, at height, or on a surface you cannot identify with confidence, the risk of permanent damage outweighs the saving.

Do you work throughout Shelley?

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.

Before you commit to anybody

Ask who will actually be on the roof. Whether the crew are employees or subcontractors matters most when a warranty claim arises, since a workmanship warranty from a business that subcontracts everything and supervises nothing is a document rather than a protection.
