Replacing an asbestos garage roof involves more than just switching out materials; it requires careful planning, safe removal, and the expertise of experienced professionals.
If you’re considering replacing your asbestos garage roof, this guide will help you understand the costs and steps involved.
Why Replace an Asbestos Garage Roof?
Asbestos garage roofs were common in previous generations due to their durability and cost-effectiveness. However, we now know that asbestos can pose serious health risks when its fibres become airborne, which can happen with wear over time, damage, or during removal.
A larger asbestos roof replacement like this one can cost more than a single garage. Read on to learn why.
A leaking or deteriorating asbestos garage roof is not only a structural concern but also a potential hazard to everyone. Replacing it ensures the safety of you and those around you while adding value to your property for years to come.
What Influences the Cost of Replacing Asbestos Roofing?
The cost of replacing an asbestos garage roof depends on a few factors…
Roof Size
The size of your garage roof is a key cost driver. Asbestos must be removed before replacement, with higher costs for larger garages.
| Type | Size | Avg. Removal Cost |
| Single Garage | 3m x 6m | £800 + VAT |
| Double Garage | 5.5m x 6m | £1,200 + VAT |
| Three Car Garage | 9m x 6m | £1,800 + VAT |
*Estimated costs for low-intensity jobs.
Larger roofs naturally require more materials for replacement and additional labour for installation, which increases the overall expense. Accurate measurements are essential to ensure proper budgeting and avoid surprises.
Costs of Replacement Material
The type of material you select for your new roof also impacts the cost. While corrugated steel is by far the most popular option, there are a variety of choices; fibreglass, EPDM rubber and other composite materials all vary in price and durability. Appearance, weather resilience, and maintenance requirements should all be considered.
| Material | Avg. Material Cost (per m²) | Avg. Labour Cost (per m²) | Avg. Total Cost (per m²) | Lifespan | Estimated Cost per Year | Maintenance costs |
| Steel Roofing Sheets | £25 – £50 | £15 – £30 | £40 – £80 | 40+ years | £10 – £20 | Average |
| EPDM Rubber Roof | £45 – £70 | £20 – £35 | £65 – £105 | 50 years | £12 – £25 | Low |
| GRP Fibreglass Roof | £70 – £100 | £25 – £40 | £95 – £140 | 25–30 years | £35 – £60 | Low |
| Onduline Bitumen | £10 – £20 | £10 – £20 | £20 – £40 | 10–15 years | £10 – £30 | Average |
| Concrete Fibre Sheets | £30 – £60 | £15 – £30 | £45 – £90 | 30+ years | £15 – £30 | Average |
*Prices listed above are estimates and may vary based on factors such as location, contractor rates, roof size, material availability, and the complexity of the project.
This table breaks down material, labour, and installation costs, with a lifespan-based analysis to help you make an inform decisions based on budget and garage needs when replacing your asbestos garage roof.
Structural Condition of the Garage
If the underlying garage structure has been compromised due to age, wear, or asbestos-related damage, additional repairs or reinforcements may be necessary.
This includes fixing joists, beams, or other support elements to ensure the new roof can be installed safely and securely. Structural repairs can notably increase costs but are crucial for long-term durability.
Accessibility
Asbestos garage roofs in tight spaces or crowded areas can be challenging to access, requiring additional time and effort to complete the work safely. Factors like limited entry points, uneven ground, or steep roof angles can further complicate asbestos removal and roof installation.
As a result, labour costs may increase, raising the overall replacement price. Planning for accessibility issues in advance can help minimise delays and unexpected expenses.
Asbestos Transport and Disposal
Removing asbestos safely and disposing of it in compliance with UK laws and regulations is non-negotiable.
This process requires licensed professionals equipped to handle asbestos materials, before disposal with an authorised landfill.
The complexity and condition of the asbestos can also influence roof replacement costs, as damaged or frail asbestos materials may be more resource intensive to transport safely.
How Much Does an Asbestos Roof Replacement Cost?
The cost of replacing an asbestos garage roof can range widely depending on the factors listed above. Below is an estimated breakdown to give you an idea:
| Garage Size | Total Material Cost | Total Labour Cost | Additional Costs | Total Estimated Cost |
| Small | £660 – £2,500 | £825 – £2,500 | £500 – £1,000 | £1,900 – £5,900 |
| Large | £1,300 – £4,900 | £1,650 – £4,900 | £750 – £1,500 | £3,720 – £11,500 |
*Estimated average costs, assuming a steel sheet replacement roof and low intensity job.
Replacing an asbestos garage roof typically costs between £1,900 and £11,500, depending on the size and complexity of the job. This includes removal and disposal by licensed professionals, as well as installation of a new roof with materials like steel, rubber, or fibreglass. Accurate measurements and material choice are key to managing costs effectively.

Top Garage Roof Replacement Materials and Costs
Selecting the right materials for your roof replacement is crucial for durability, looks, and cost-effectiveness. Here are the key options to consider:
Steel Roofing Sheets
Steel roofing sheets are low cost. They’re usually the most popular choice, offering unmatched durability and strength at a great price. Resistant to weather damage and low-maintenance, they are a practical option for garages needing a robust and long-lasting roof. Available in various finishes and colours, steel sheets also enhance the visual appeal of your garage.
EPDM Rubber Roofs
EPDM rubber roofs have a higher cost. They are a versatile and long-lasting choice.

What’s the Process of Replacing an Asbestos Roof?
Replacing an asbestos garage roof involves several critical steps:
- Reach out to a professional: Discuss the condition and size of the garage. They’ll be able to explain your options and the types of replacement roofs that are suitable. Finally, they’ll be able to offer you a quote outlining costs for the work required. Modern tools like Google Maps allows for the size of the asbestos roof to be measured without an in-person visit, meaning you can get a quote for the replacement in just a few minutes.
- Asbestos Removal: Licensed contractors will arrive, conduct an assessment, then safely remove and dispose of the asbestos materials, ensuring compliance with all UK regulations.
- Checking the structure: Before fitting a new roof, the garage will be checked. If there’s damage to the structure, repairs will be carried out before installing the new roof. This ensures that the garage roof replacement will be sturdy and last for years to come.
- Installation of New Roof: The chosen roofing material is installed, providing a durable and modern finish. If you’ve asked your roofer to fit new trimmings or guttering to the garage roof, they’ll install it after the new roof is fitted.
- Final Inspection: A thorough inspection ensures the work has been completed to a high standard. You’ll also be given a hazardous waste consignment notice, which details that the disposal of your asbestos has been handled properly and legally.

Financing and Grants for Asbestos Roof Replacement Costs
Replacing an asbestos garage roof can be a major investment, and many property owners want to know if there’s financial assistance available.
Yes and no. While there are no nationwide government grants specifically for asbestos garage roof replacement, some local councils may offer financial assistance.
The UK government previously ran asbestos removal grants, such as the Northern Ireland scheme, but these have ended as of 2023. However, you may still be able to reduce costs through local council support, tax relief, or financing depending on your circumstances.
Tax Relief & Financial Support Options
1. Land Remediation Relief (Corporation Tax Relief)
For businesses, landlords, and property developers, the UK government offers Land Remediation Relief (LRR), allowing significant tax deductions on asbestos removal costs.
Who Can Apply?
✅ Businesses that own garages, barns, or industrial buildings with asbestos roofs
✅ Commercial landlords replacing an asbestos roof on rental properties
✅ Developers purchasing land or buildings contaminated with asbestos
How It Works
- 100% tax deduction for the cost of removing an asbestos garage roof or other contaminated structures.
- An additional 50% tax relief on expenses related to asbestos disposal and site remediation.
Example: Asbestos Garage Roof Replacement Cost & Tax Savings
“A business owner replacing a block of asbestos garage roofs faces a total cost of £10,000, with £2,500 for asbestos removal and £7,500 for a new steel roof.
Fortunately, under Land Remediation Relief, they can deduct the full asbestos removal cost from taxable profits, plus an additional 50% relief on that expense, reducing their tax liability.
With a 25% corporation tax rate, this results in a total tax saving of £2,812, making the actual cost significantly lower while ensuring a safer, compliant property.”
Note: This applies to commercial properties, not private homes. Consult a tax expert to determine eligibility.
2. Stamp Duty Land Tax (SDLT) Relief for Uninhabitable Properties
If you’re purchasing land or a property with outbuildings that are deemed uninhabitable due to asbestos, you may qualify for Stamp Duty Land Tax (SDLT) relief.
How It Works
- If a property is deemed uninhabitable, it may qualify for lower SDLT rates.
- No Stamp Duty on the first £150,000 of the purchase price.
- Reduced rates on amounts exceeding £150,000.
What Makes a Property “Uninhabitable”?
- Widespread asbestos contamination in garages, barns, or outbuildings.
- Structural instability due to an asbestos roof in poor condition.
- Significant water damage, rot, or mould.
- Severe plumbing, electrical, or heating issues.
Note: This applies to properties with severe asbestos contamination. Always confirm eligibility with a legal expert.
3. Local Authority & Council Assistance
Some UK councils provide small grants or loans for property improvements, including asbestos garage roof removal.
Tips
- Check your local authority’s policies—some offer Housing Repair Assistance Schemes that may partially cover asbestos removal costs.
- The UK government provides a postcode-based tool to find asbestos-related support in your area:
Check your local council’s asbestos policies.
Who Can Apply?
Property owners replacing an asbestos garage roof and those in areas where councils provide home improvement grants.
4. Private Financing & Low-Interest Loans
For those without tax relief eligibility, financing options can help spread the cost of an asbestos garage roof replacement.
Options Include:
✅ Personal loans for property renovations
✅ Home equity loans for outbuilding upgrades
✅ Staged payment plans (offered by select asbestos removal firms)
Who Can Apply?
Homeowners or landlords replacing an asbestos garage roof but needing flexible payment options.
How to Reduce the Cost of Asbestos Garage Roof Replacement
Even without direct grants, there are ways to reduce asbestos removal costs:
✅ Property Buyers: Look into SDLT relief for asbestos-contaminated properties.

Is DIY Asbestos Garage Roof Removal an Option?
DIY asbestos removal is typically illegal. Handling damaged or frail asbestos without a license or failing to follow strict disposal regulations can result in substantial fines, legal action, and criminal liability, which outweigh any cost you imagine you might save.
UK authorities strictly enforce these laws to protect public health and the environment. Moreover, attempting to remove an asbestos garage roof yourself is extremely hazardous and strongly discouraged. Asbestos fibres are highly dangerous when disturbed, becoming airborne and posing a severe risk to your health and the health of others.
Always hire licensed professionals who are trained to remove and dispose of asbestos safely. Attempting to save costs by going DIY may ultimately cost you much more in both health and legal costs.
