Asbestos cement roofing exists on a great many Perth homes and outbuildings built before the mid eighties. It is not automatically dangerous and it is absolutely not something to clean, drill, cut or walk on.
This article is about identifying it and understanding the correct process. It is not instructions for handling it yourself, because that is neither legal nor sensible.
Where it turns up
Corrugated roof sheeting on houses, sheds, carports, garages and patios, most commonly on buildings from the fifties through to the early eighties.
Also in eaves linings, Gutter Replacement Perth on some older buildings and in flat sheeting used for outbuildings.
It was extremely common in Western Australia and older suburbs carry a great deal of it still, particularly on sheds and rear additions rather than main dwellings.
Identifying it, without disturbing it
Corrugated sheeting with a fibrous grey appearance, often weathered to a mottled surface, on a building of that era is a reasonable suspicion.
It cannot be confirmed visually with certainty. Testing by a competent laboratory using a properly collected sample is the only definitive answer.
The safe approach with anything suspected is to leave it alone and get advice. Undisturbed material in sound condition is generally low risk.
What makes it dangerous
Fibres released into the air. That happens when the material is broken, cut, drilled, sanded, pressure cleaned or walked on.
Weathered sheeting that has become friable is more prone to releasing fibres, which is why deteriorated material warrants attention rather than being ignored indefinitely.
Pressure Cleaning Perth an asbestos roof is among the worst things anybody can do and it is still occasionally offered by operators who either do not know or do not care.
The legal position in Western Australia
Removal of asbestos containing material is regulated. There are limits on what a homeowner may do and requirements for licensed removalists above defined quantities.
Disposal is also regulated. It cannot go in general waste and must be taken to a facility licensed to accept it, wrapped and transported appropriately.
This is an area where doing it properly protects you legally as well as physically.
What a proper removal looks like
Assessment and confirmation of the material first.
A removal plan appropriate to the quantity and condition, with the site controlled and occupants managed.
Sheets removed whole wherever possible rather than broken, wetted down to suppress fibre release, wrapped and sealed for transport.
Disposal at a licensed facility with documentation.
Clearance of the site before the replacement roof is installed.
Replacing what was there
Once removed, the structure underneath is exposed and can be assessed properly. Battens and framing on buildings of that age frequently need attention.
The replacement is usually sheet metal, which is lighter than what came off and straightforward to install on prepared framing.
Sarking, insulation and ventilation can all be addressed at the same time and this is the sensible moment to do it.
What not to do
Do not pressure clean it. Do not paint over it without proper advice. Do not drill it to hang anything. Do not walk on it, which is also a fall risk because aged sheeting is brittle.
Do not break it up for easier disposal.
Do not accept a quote from anybody who proposes any of the above.
If it is damaged by a storm
Storm Damage Roof Repairs Perth to asbestos sheeting needs careful handling. Broken material is exactly the condition that releases fibres.
Keep people away from the area, do not attempt to clear debris yourself and get appropriately qualified people to assess it.
Insurance Roof Repairs Perths deal with this regularly and the correct process is well established. It is not a reason to panic, but it is a reason to stop and get advice before touching anything.
Common questions
Do I have to remove it? Not necessarily. Undisturbed material in sound condition is generally left alone. Deteriorating or damaged material is a different matter.
Does it affect selling? It must be disclosed where known and building inspections identify it routinely.
Can it be coated instead of removed? There are encapsulation approaches and whether they suit depends entirely on condition and circumstances. It is a question for somebody assessing the actual material.

Why so much of it exists here
Asbestos cement sheeting was cheap, durable, fire resistant and easy to work with and it was used extensively across Western Australia through the post war building boom.
Sheds, garages, carports, patio roofs and rear additions carry it most commonly, though plenty of main dwellings do too.
Wittenoom's history gives the material a particular resonance in this state and awareness is generally higher here than elsewhere in the country.
Condition matters more than presence
Sound, painted, undisturbed sheeting is generally considered low risk and is frequently left in place.
Weathered, cracked, broken or friable material is a different proposition, because deterioration is what releases fibres.
Age alone does not determine condition. A well maintained sheet roof from the sixties can be in better shape than a neglected one from the eighties.
Getting advice without alarm
Suspecting asbestos is not an Emergency Roof Repairs Perth. It is a reason to stop, avoid disturbing the material and seek qualified advice.
Testing is inexpensive relative to the certainty it provides and sampling should be done by somebody competent rather than by scraping a bit off yourself.
Once identified, you have options and time. Panic leads to bad decisions, including the very worst one of attempting removal personally.
Budgeting for it
Licensed removal costs more than ordinary demolition because the process, the protective measures and the disposal are all regulated.
That cost is not padding. It reflects genuine compliance obligations and appropriate protection for everybody involved.
A quote significantly below others for asbestos work is a warning rather than a bargain, because the corners being cut are the ones that matter.

Where to find reliable information
The Western Australian Department of Health publishes guidance on asbestos in homes, including identification and safe management.
WorkSafe governs the occupational side, covering licensing requirements and permissible quantities for unlicensed removal.
Local governments handle disposal arrangements and can advise which facilities accept the material.
Those three sources answer nearly every question a homeowner has and none of them are trying to sell you anything.
Approach commercial advice with the same scepticism you would apply anywhere. Somebody quoting removal has an interest in the answer being removal.
We assess and coordinate licensed removal across Perth including Rockingham, Safety Bay, Warnbro and Baldivis. Ring 0421 768 842.One additional consideration for landlords and property managers. Disclosure obligations attach to known asbestos containing material and tenants have a legitimate interest in being informed about the buildings they occupy.
Documenting what exists, where and in what condition protects everybody. An asbestos register sounds bureaucratic for a residential property, yet a single page noting the shed roof and its condition saves confusion later.
Insurance Roof Repairs Perths treat asbestos differently and policies vary considerably. Some cover removal following an insurable event, others exclude it or cap contributions. Reading yours before a storm rather than afterwards is worthwhile.
What removal actually costs and why
Licensed removal costs more than ordinary demolition and the reasons are concrete rather than padding. Notification requirements, controlled work areas, protective equipment, wetting down to suppress fibre release, sealed wrapping, dedicated transport and disposal at a facility licensed to accept the material.
Every one of those is an obligation rather than a service upgrade. A quote materially below others for asbestos work is not a bargain, because the difference is nearly always a step being skipped and the steps exist to protect the people in the house.
Ask what licence class the removalist holds, how the waste will be transported and which facility will receive it. Legitimate operators answer immediately because they deal with it daily.
Living in the house during removal
For a shed or a carport roof, usually straightforward. Occupants stay clear of the work area, windows on that side stay shut and washing comes off the line.
For a main dwelling roof it is more involved and depending on scale you may be asked to be elsewhere for the removal day. That is a precaution rather than an alarm.
Pets matter and get forgotten. Cats in particular investigate work areas and a dog barking at a crew in protective equipment makes everybody's day harder.
Gardens directly beneath get covered. Vegetables underneath a roof being removed are worth harvesting beforehand or accepting the loss of.
