Fibro and Asbestos Roofs in Warilla and Oak Flats

If you own — or are about to buy — an older fibro home in Warilla, Oak Flats, Mount Warrigal or Barrack Heights, there's a fair chance the roof or wall sheeting contains asbestos. That isn't a reason to panic, but it is a reason to know the facts before anyone touches it.

This guide explains, in plain language, how to recognise a likely asbestos roof, why an undamaged one is usually low-risk, what NSW law actually requires for removal, and how Shellharbour City Council's free disposal service works. One thing up front, so it's clear: we do not carry out unlicensed asbestos removal, and nothing here is DIY removal guidance. Removal is specialist, licensed work — our role is the roofing side and pointing you to the right people for the rest.

What is fibro, and which Shellharbour suburbs have the most pre-1988 homes?

"Fibro" is fibre-cement sheeting — a cheap, durable building material that dominated mid-century Australian housing. The problem is that until 1987, fibro products commonly contained asbestos for strength. Manufacturing of asbestos-containing products was phased out by 1987 and the material was fully banned in 2003.

That timeline maps directly onto Shellharbour's older suburbs. Warilla was granted township status in 1951 and built out heavily through the 1950s and 1960s. Region Illawarra's local reporting traces NSW Housing Commission fibro homes in the Lake South / Warilla area from the early 1940s, with the Warilla extension populated from the early 1960s — and residents who grew up in those fibro Commission houses before families moved on to Oak Flats. Mount Warrigal and Barrack Heights followed the same pattern, largely built between the 1950s and 1970s.

The practical rule: if your home was built or re-roofed before 1987, treat it as potentially containing asbestos until a laboratory confirms otherwise.

How to tell if your roof contains asbestos cement (visual identification guide)

Visual identification can raise a flag, but it can never confirm asbestos on its own — old asbestos cement and modern asbestos-free fibre-cement can look almost identical. Use these cues to decide whether testing is warranted, not to make a final call:

• Age first. A pre-1987 build or re-roof is the single biggest indicator.
• Corrugated grey sheeting with a flatter, lower-profile corrugation than modern Colorbond.
• A fibrous, slightly chalky surface when weathered, sometimes with surface lichen or moss.
• Brittleness — asbestos cement cracks rather than dents.

Do not break, cut, scrape or sand a piece to "check." Disturbing it is exactly what releases fibres. If the cues above apply, the next step is a sample taken and tested by a NATA-accredited laboratory — the only definitive confirmation. SafeWork NSW also runs an asbestos finder tool and recommends professional testing before any disturbance.

Why undisturbed bonded asbestos is low-risk — but disturbance is not

This is the part that calms a lot of new owners down. Asbestos cement is bonded (non-friable) asbestos: the fibres are locked into the cement matrix. While the sheeting is intact and in good condition, those fibres aren't going anywhere, and the airborne risk is low.

The risk is created by disturbance — drilling for a satellite dish, cutting a vent, pressure washing, walking on and cracking sheets, or letting weathered, damaged sheeting break down over time. That's when fibres can become airborne.

So if your asbestos roof is intact, sealed and in good order, the safest course is often to leave it undisturbed and monitor it rather than rush to remove it. Removal becomes the right move when the roof is damaged, deteriorating, or you're re-roofing anyway.

NSW law: when you must use a licensed asbestos removalist

NSW Work Health and Safety Regulations 2017 set clear thresholds:

• Class B licence — required to remove more than 10 square metres of bonded (non-friable) asbestos.
• Class A licence — required for any amount of friable asbestos.

A whole fibro roof is far more than 10 square metres, which puts roof removal squarely in licensed-removalist territory. On top of that, SafeWork NSW recommends using a licensed removalist for any asbestos work, regardless of quantity. For the full rules and a way to find licensed removalists, go to safework.nsw.gov.au and asbestos.nsw.gov.au.

The 10 square metre rule explained simply

The 10 square metre figure is the legal line for bonded asbestos. In plain terms:

• You may remove up to 10 square metres of bonded asbestos without a licence.
• Anything beyond 10 square metres legally requires a Class B (or Class A) licensed removalist.
• Friable asbestos always requires a Class A licensed removalist — no threshold, no exception.

Because a roof is almost always well over 10 square metres, it falls outside any self-removal allowance. Treat the 10 square metre allowance as something for a tiny patch, not a roof — and even then, SafeWork NSW's advice is to use a licensed removalist anyway. We do not recommend DIY removal.

Shellharbour City Council's free asbestos disposal service — how it works

This is the concrete local detail most national guides leave out. Shellharbour City Council runs a residential asbestos disposal service for Shellharbour and Kiama LGA residents (not contractors). Here's how it works:

1. Check eligibility. It's for residents only, and accepts a maximum of 100 kg or 10 square metres of bonded (non-friable) asbestos. Friable asbestos is not accepted.
2. Apply to Council first. You must lodge an application before starting any work.
3. Council inspection. A Council Supervisor arranges an inspection as part of the process.
4. Dispose at Dunmore. Approved disposal is at the Dunmore Recycling and Waste Disposal Depot.
5. Over the limit? Quantities above 100 kg or 10 square metres must go through a licensed Class A or Class B contractor — they handle removal and disposal.
6. Transport rule. If you transport more than 100 kg or 10 square metres of asbestos waste yourself, you must notify the NSW EPA within 24 hours of delivery using the "disposing of household asbestos" form.

Contact Council on 1300 121 344, Monday to Friday 8:30am–5:00pm, to start an application or check the current requirements.

Because a full roof exceeds the Council service's limit, in practice a roof removal goes through a licensed contractor — but the service is genuinely useful for small bonded offcuts left over from other work.

What happens during a professional fibro roof inspection?

A fibro-era roof inspection is different from a standard one. We're looking at:

• Likely material — whether the roof appears to be asbestos cement, flagged for NATA-accredited testing rather than guessed at.
• Condition and disturbance risk — is it intact and low-risk, or damaged and deteriorating?
• Structure, flashings and fasteners beneath and around the sheeting.
• Replacement scope — what a safe removal-and-replace pathway looks like and a realistic budget picture.

We give you an honest written assessment. For the definitive asbestos confirmation you still need a laboratory test, and for the removal you need a licensed removalist — we'll tell you plainly which step is which. See roof inspections and reports in Shellharbour for what's included.

Asbestos roof removal and replacement: what does it cost in the Illawarra? (honest ranges)

We won't quote a fixed price, because an honest one doesn't exist without seeing the roof. Cost is driven by:

• Roof size and pitch — more area, more cost on both removal and replacement.
• Height and access — a tight or two-storey site costs more to work safely.
• Removal complexity — condition of the sheeting and disposal logistics.
• Your replacement choice — typically a switch to coastal-rated metal and Colorbond roofing, which is lighter and far better suited to Shellharbour's salt exposure than the old sheeting.

The clean way to budget: have the licensed asbestos removal quoted by a SafeWork NSW-licensed removalist as one line item, and have the replacement roof quoted separately. We scope and price the replacement side honestly; the removal is the removalist's specialist quote. If you later find leaks or damage on an existing roof before replacement, that's a roof repair in Shellharbour conversation.

Your next step: book a pre-purchase or fibro-era roof inspection

If you're buying a pre-1988 fibro home in Oak Flats, Warilla or Barrack Heights, get a fibro-era assessment before you exchange — not a generic inspection. It tells you whether the roof is likely asbestos, its condition and disturbance risk, and a realistic replacement scope, so the roof is priced into your decision rather than a nasty surprise after settlement.

If you already own one and the roof is intact, you often don't need to do anything urgent — monitor it and avoid disturbing it. If it's damaged or you're planning works, that's the time to bring in a licensed removalist for the asbestos and us for the new roof.

FAQ

Does my fibro house in Warilla or Oak Flats have asbestos? Possibly — asbestos was common in fibro until 1987, and these suburbs were largely built in the 1950s–1970s. Treat any pre-1987 roof as suspect until a NATA-accredited laboratory test confirms otherwise.

Is it safe to leave an asbestos roof in place if it isn't damaged? Usually yes. Undisturbed bonded asbestos cement in good condition is low-risk; the danger comes from disturbance. Monitoring an intact roof is often safer than removing it.

When must I use a licensed asbestos removalist? For more than 10 square metres of bonded asbestos (Class B licence) or any friable asbestos (Class A licence). A roof exceeds 10 square metres, so it's licensed work. SafeWork NSW recommends a licensed removalist for any asbestos.

Can I remove asbestos fibro myself? For a roof, no — it's well over the 10 square metre self-removal limit, and we recommend against DIY asbestos removal entirely. Use a SafeWork NSW-licensed removalist and refer to asbestos.nsw.gov.au.

How does Shellharbour Council's disposal service work? Residents can dispose of up to 100 kg / 10 square metres of bonded asbestos via Council — apply first, a Supervisor inspects, then dispose at the Dunmore depot. Over the limit needs a licensed contractor. Council: 1300 121 344.

Who do I call for removal? A SafeWork NSW-licensed removalist for the asbestos itself — we do not do unlicensed removal. For the fibro-era inspection and the new roof, call us.
