If you are unsure how much to removal asbestos roof, the short answer is that it varies, often depending on your roof’s size, the materials used, and local safety regulations.
On average, asbestos removal in New Zealand can cost anywhere from $70 to $150 per square metre, but that range can shift based on factors like complexity and disposal fees. The reassuring news is that once you know what influences the price, you can make smart decisions to protect your home and budget.
In this ultimate guide, you will learn why asbestos roofing is risky, how removal costs add up, and the simple steps to replace it with a safer option.
Understand asbestos roofing
Asbestos is a naturally occurring mineral fibre once prized for its heat resistance and durability. Decades ago, many New Zealand homes used asbestos in roofing panels, often marketed as a long-lasting solution that could endure harsh weather.
Yet health experts discovered that asbestos fibres, when disturbed or aged, can become airborne. Breathing these fibres can be harmful to your lungs. If you own an older home, there is a good chance your roof may have asbestos components. The standard advice is to tread carefully if you suspect asbestos so you do not accidentally release fibres into the air.
Discovering asbestos in your roof can feel overwhelming. However, knowing that specialised help is widely available can give you peace of mind. Contractors with training in asbestos removal know how to assess your roof’s condition, safely remove the sheets, and ensure proper disposal. Armed with this knowledge, you will be ready to make an informed choice about your next steps.
Assess the dangers
While dormant asbestos poses a lower risk, any roofing in poor shape can become a hazard. Weathering, cracks, or leaks can stir up asbestos fibres, raising health concerns for you and your family. A 2019 health review indicated that homes with ageing asbestos roofs had a higher chance of fibre release if the roof was disturbed for roof repairs or new installations (like solar panels).
If you see brittle, chipped materials near the roofing edges or notice debris collecting in gutters, the best move is to contact a professional asbestos tester. You will often get these signs when a roof has outlived its expected lifespan, typically 30 or more years. Identifying the problem early can help limit long-term risks, keep costs down, and give you options for timely replacement.
Estimate your removal cost
One of the first questions that pops up when you learn you have asbestos roofing is: “How much will it cost to remove?” Although every home is different, it can be helpful to think of costs on a per-square-metre basis. In New Zealand, you might pay:
- $70–$90 per m² for straightforward removal on a single-storey property, with easy roof access
- $90–$120 per m² for multi-storey homes or slightly more challenging access
- $120–$150 per m² for steep roofs, multiple architectural details, or any property where you need special safety measures
These numbers typically cover the labour, protective equipment, and disposal fees. Some contractors may also include testing and site clean-up in the total. Others provide these services as separate line items in your quote. Either way, ask for a breakdown to avoid confusion and to budget accordingly.
Why the cost can vary
If you are quoted more or less than the average range, do not panic. Differences often stem from the difficulty of removing asbestos from specific sections, the gear needed, and local landfill or disposal restrictions.
A rural property that is far from an approved disposal site may see slightly higher transport charges. On the flip side, an easy-access, flat roof in an urban area might reduce labour hours.
Potential add-ons
Some homeowners opt to re-roof immediately after removal, which means there could be an additional charge for installing new materials. If you choose a premium roofing product, your final bill will rise.
This is why it is smart to request specific quotes for both removal and replacement, so you can compare your options in full. Learning how these elements stack up will help you avoid hidden surprises when the bills arrive.
Factors that affect cost
Asbestos roof removal pricing can look confusing at first. Below are some of the main aspects that typically shape your final bill:
1. Roof condition
If you have heavy damage, crumbling sections, or widespread wear, it often requires extra safety measures. This can mean more time on-site, higher labour costs, and specialised disposal handling.
2. Access difficulty
If your roof has a steep pitch or multiple gables, the removal team might need scaffolding or extra harnesses. Hard-to-reach spots typically lengthen the project timeline.
3. Local disposal fees
Asbestos must go to a licensed facility. Some regions charge higher disposal fees, which the contractor may pass on to you. Where permitted, large loads of asbestos waste can also require multiple trips.
4. Testing and inspection
Before and after removal, conducting air-quality checks or materials testing may add up. However, these steps help confirm that fibres are not present in dangerous amounts.
5. Project timeline
If your home improvement schedule is tight, some companies may charge extra for rushed projects or weekend work. Alternatively, a flexible timeframe can reduce your costs if crews fit you into a broader schedule.
6. Size of the roof area
The simplest factor is still one of the biggest influences: how many square metres of asbestos roofing do you have to remove? More area means more labour and protective equipment, often translating into a higher overall invoice.
By recognising these variables, you will have a clearer sense of what to expect. You can also prioritise what matters most to you, whether that is speedy removal, budget-friendly solutions, or a straightforward schedule.
Know the removal process
Understanding the typical steps in removing an asbestos roof helps you prepare mentally and practically. It also shows why professional crews command the fees they do, as the process requires care, compliance with regulations, and special equipment.
1. Inspection and sampling
A qualified asbestos inspector takes samples of the roofing material. The main goal here is to confirm asbestos content and identify its type. They often follow this step with an air quality test around your property.
2. Safety setup
On removal day, the crew sets up the site with barriers, signage, and protective gear. They close off areas to reduce the risk of airborne particles. Everyone on-site will wear a full protective suit and a respirator.
3. Careful sheet removal
Using slow, deliberate techniques, the crew detaches sections of the asbestos roof. They try to avoid breaking materials, which can release fibres. Workers spray water or a binding solution to keep dust levels low.
4. Secure wrapping
Asbestos sheets are wrapped in heavy-duty plastic, labelled for hazardous waste, and placed in special containers or trucks for safe transport. This minimises the chance of fibre spread.
5. Site clean-up
Thorough vacuuming or wet wiping is common after removal. Teams double-check the area to ensure no loose debris remains. Air tests may follow to confirm that the environment is safe.
6. Disposal
The last step involves taking the packaged asbestos waste to a licensed disposal facility, which meets government regulations. You will likely receive a certificate of proper disposal.
When each of these steps is done right, you minimise the health risk and comply with legal requirements. The process might sound daunting, but experienced contractors follow it daily. You will remain informed throughout, from the initial inspection to the final disposal receipt.
Choose professional help
While do-it-yourself projects can cut costs in many home improvement areas, asbestos is an exception. The health implications and strict regulations make expert help the best option. Professional removal firms have experience finding hidden asbestos, using the correct protective equipment, and disposing of waste legally.
In New Zealand, you are generally required to hire licensed roofing professionals if the asbestos area exceeds a certain size or if the material is friable (easily crumbled). Even if you think you can handle a small section, consulting a certified contractor first is wise. Their guidance often prevents accidental damage that can release fibres.
Many homeowners turn to well-reviewed local experts like Kings Roofing for a safe, consistent experience. By scheduling an inspection, you will have a roadmap for each part of the project, saving you the stress of guesswork or unplanned setbacks.
What to ask a contractor
Before you sign a removal contract, consider asking:
- Are you licensed for asbestos removal in New Zealand?
- Can I see your safety protocols and disposal procedures?
- Do you include air-quality testing, or should I hire a separate tester?
- How long will the removal take, and how many people will work on-site?
- Is roofing replacement handled by your team or a partner company?
These questions will help you compare quotes with clarity. You will also get a sense of each contractor’s experience and approach, which matters as much as the final price tag.
Consider safer roofing options
Once the asbestos is gone, you can select a newer roofing material that meets your budget and suits your home’s style. In New Zealand, popular alternatives include:
- Metal roofing: Known for its durability and relatively low maintenance.
- Concrete or clay tiles: Often heavier and pricier, but can last decades.
- Asphalt shingles: A more affordable choice, though lifespan can be shorter.
- Composite roofing: Made with modern materials that mimic slate or wood, minus the fire risk.
Each option has pros and cons in terms of insulation, aesthetic appeal, and cost. It may be wise to gather multiple quotes for both removal and new installation to see the total expense in one view.
For instance, if you choose metal roofing, labour costs can shift based on the intricacy of your roof’s shape. Confirm the warranty terms as well, so you have peace of mind for the long haul.

Removing an asbestos roof can feel like a big undertaking, but it is a smart move for your household’s health. A typical asbestos roof removal can range from about $70 to $150 per square metre in New Zealand, shaped by roof size, existing damage, and the logistics of safe disposal. Professional help is the safest route, and reputable contractors will guide you through every stage, from testing to final disposal.

Common questions answered
Can I remove asbestos roofing on my own?
You can legally remove small amounts of non-friable asbestos under certain regulations. However, the risks are high if you lack training or safety gear. One slip-up can leave your family exposed to airborne fibres. Hiring licensed professionals is strongly recommended for any roof-sized asbestos project.
Do I need permits for asbestos removal?
Local councils may have specific rules. In some cases, you need to notify WorkSafe New Zealand if the project surpasses certain thresholds. A professional contractor will know the details and can handle any required paperwork or notifications.
What if my roof has asbestos but is in good shape?
If the material is undamaged, it may not pose an immediate threat. Still, plan for eventual replacement, especially if you might renovate or install new fixtures on the roof. Regularly monitoring the roof’s condition is a smart approach. Consult a specialist if you see any change in colour, cracks, or leaks.
Does insurance cover asbestos roof replacement?
Many insurance policies do not include asbestos removal as part of standard coverage. However, some may offer partial coverage if the roof is damaged by an insured event, like a severe storm. Read your policy or consult your insurer to clarify what is covered.
By understanding your options and taking each step with care, you can replace your asbestos roof without breaking your budget or compromising on safety.
