Asbestos Roof Removal and Colorbond Replacement in Geelong

Asbestos cement roofing, often called super six or fibro sheeting, sits on a lot of Geelong sheds, garages, carports and older homes. It is also the removal we treat with the most care, because roof sheeting is weathered, brittle, and worked on from above.

Why roofs are the higher-risk job

Most asbestos in a house is relatively stable. It is fixed, painted, and left alone. Roof sheeting is the opposite: it has spent decades in full sun, wind and rain, and the surface has degraded. Weathered asbestos cement releases fibres far more readily than the same material indoors.

Add the working environment. It is at height, on a surface that is not designed to be walked on, and asbestos cement sheeting becomes progressively more brittle with age. People fall through these roofs. That combination of fibre risk and fall risk is why this work is licensed and why it is not a job to take on yourself.

The licensing, in plain terms

Asbestos removal in Victoria is split by material type. Non-friable asbestos, which includes intact asbestos cement sheeting, requires a Class B licence at minimum. Friable asbestos, which is material that can be crumbled by hand pressure when dry, requires a Class A licence.

The point that catches people out is that a roof does not always stay non-friable. Severely weathered, delaminating or fire-damaged sheeting can be assessed as friable, which changes the licence class required, the controls, and the cost. That assessment needs to happen before the job is priced, not on the morning.

Removal work must be notified to the regulator in advance, and there are minimum notice periods. That is one reason these jobs cannot be booked for tomorrow.

How the removal actually runs

Good asbestos roof removal is slow and deliberate, and that is the point.

The site is set up first: exclusion zones below the work area, signage, and protection of the ground and any adjacent surfaces so that debris and dust can be collected rather than washed into the soil or stormwater. Neighbouring properties are considered here too, particularly on the tighter blocks through Norlane and Corio.

The sheeting is then removed whole wherever possible. This is the single most important control. Sheets are unscrewed or the fixings are cut, and each sheet is lowered rather than dropped. No cutting, no grinding, no breaking sheets for easier handling, and no high-pressure water blasting. Anything that abrades the surface generates airborne fibre.

Sheets are wrapped and sealed as they come off, usually in heavy plastic, labelled, and stacked for transport. Loose debris, screws, and the accumulated dust in the roof space and gutters are collected and treated as contaminated waste, because that dust is often the most fibre-rich part of the job.

Air monitoring is used where the risk assessment calls for it, and on friable work it is required.

Disposal and the paperwork

Asbestos waste can only go to a facility licensed to accept it, and the transport and disposal are documented. Around Geelong that means a specific set of receiving sites, and the disposal cost is a real and unavoidable component of the quote.

What you should receive at the end is a record: disposal documentation showing where the waste went, and, where the scope requires it, a clearance certificate from an independent assessor confirming the area is safe to reoccupy. Clearance certificates matter more than people realise. They are what you produce for a builder, an insurer, or a future purchaser, and they are difficult to obtain retrospectively.

Be wary of any quote that is unusually cheap and vague about disposal. Illegal dumping of asbestos waste is exactly what that discount is buying, and the liability follows the property owner.

The gap between old roof off and new roof on

This is the practical question everyone asks: what happens to the building in between.

On most jobs the removal and the replacement are sequenced tightly, often with the new roof going on the same day or the next, section by section on larger buildings. The structure underneath is exposed once the sheeting is off, so weather is a genuine planning constraint, and these jobs are best scheduled with a clear forecast rather than in the middle of a Geelong winter front.

The battens and structure below get inspected at that point. Old asbestos roofs often sit on timber that has had a long life, and it is far cheaper to replace a failing batten while the roof is open than to discover it later.

Colorbond and modern steel sheeting is lighter than asbestos cement, which is generally helpful structurally, but it is also profiled differently, so batten spacing, fixings, flashings, and often insulation and sarking are addressed as part of the replacement rather than reusing what was there.

What it is worth doing at the same time

If you have asbestos roofing, you frequently have asbestos elsewhere: eaves, gable infills, sheds, and fencing. Doing them together is meaningfully cheaper than mobilising twice, and it means one clearance process rather than several.

It is also the right moment to have the rest of the property assessed properly if it has never been done, particularly on post-war homes through Corio, Norlane and the older parts of Newtown and Belmont.
