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 fire-resistant properties. 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 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

*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 choice; fibreglass, EPDM rubber and other composite materials all vary in price and durability. Appearance, weather resilience, and maintenance requirements should all be considered.

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

Garage roofs that are difficult to access, such as those in tight spaces or with crowded surroundings, may require extra time and effort to safely complete the work. Challenges like limited entry points, uneven ground, or steep roof angles can make the removal and installation process more complex.

As a result, additional labour costs may be incurred, which could increase the overall price of replacing an asbestos roof. Planning for accessibility issues in advance can help you better manage these potential 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 pricing, as damaged or frail asbestos materials may be more resource intensive to transport safely.

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 the most popular choice and offer 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 colors, steel sheets also enhance the visual appeal of your garage.

EPDM Rubber Roofs

EPDM rubber roofs are a versatile and long-lasting choice. Known for their excellent waterproofing and resistance to UV rays, they are ideal for flat or slightly pitched garage roofs. Easy to install and low-maintenance, EPDM is a great investment with a modern, sleek appearance.

GRP Fibreglass Roofs

GRP (Glass Reinforced Plastic) fibreglass roofs provide a seamless and highly durable solution. They are lightweight, fully waterproof, and resistant to rot or corrosion, making them a premium choice for modern garages. GRP roofs also allow for customisable finishes, adding to their aesthetic appeal.

Onduline/Bitumen Roof Sheets

Onduline or bitumen roof sheets are affordable, lightweight, and easy to install. These materials are well-suited for garages requiring a budget-friendly solution while still ensuring durability and resistance to weather conditions. They work well for pitched roofs and can provide a rustic, functional look.

Concrete Fibre Roof Sheets

Concrete fibre roof sheets are an excellent choice for garages requiring a strong, fire-resistant, and weatherproof roof. They combine durability with good thermal insulation and are particularly suitable for pitched roof designs. Their special properties and heavy weight makes them slightly more expensive than other options.

What’s the Process of Replacing an Asbestos Roof?

Replacing an asbestos garage roof involves several critical steps:

  1. 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.
  2. Asbestos Removal: Licensed contractors will safely remove and dispose of the asbestos materials, ensuring compliance with all UK regulations.
  3. 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.
  4. Installation of New Roof: The chosen roofing material is installed, providing a durable and modern finish.
  5. Final Inspection: A thorough inspection ensures the work has been completed to a high standard. You’ll also be given a hazardous waste consignment note which details that the disposal of your asbestos is being disposed of properly and legally.

Is DIY Asbestos Garage Roof Removal an Option?

DIY asbestos removal is typically illegal. Handling 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.
