Depending on the condition of the roof, you can anticipate spending an additional £200 to £500 for professional roof cleaning services. This expenditure ensures that the new roof can be installed on a clean and stable foundation, enhancing its longevity and performance.

On average, you can expect to invest between £40 to £150 per square metre for the installation of a new garage roof. Factors such as material quality, durability, and aesthetic preferences influence the overall cost of this component.

5 Crucial Factors That Influence The Cost

1.    Size Of The Roof

The size of the garage roof directly impacts the overall replacement cost. Larger roofs require more materials, labour, and disposal efforts, resulting in higher expenses.

Additionally, larger roofs may necessitate specialised equipment or additional manpower, further contributing to the overall cost.

2.    Extent Of Asbestos

The concentration and distribution of asbestos within the garage roof significantly influence the cost of replacement. Higher concentrations or widespread asbestos contamination may require more extensive removal procedures and safety precautions, driving up the overall expense.

Assessing the extent of asbestos contamination is essential for accurately estimating the cost of replacement and ensuring compliance with safety regulations.

3.    Accessibility

The accessibility of the garage roof can affect the ease and efficiency of the replacement process, thereby influencing costs. Roofs that are difficult to access or located in tight spaces may require specialised equipment or alternative access methods, which eventually leads to additional expenses.

Factors such as the height of the roof, surrounding obstacles, and available workspace can impact the complexity of the replacement project and subsequent costs.

4.    Roof Complexity

Intricate roof designs, such as multiple angles, slopes, or architectural features, may require more time and expertise to dismantle and replace effectively. Additionally, complex roof structures may necessitate custom solutions or specialised materials, adding to the total expense of replacement.

5.    Additional Precautions

Special precautions may be required to ensure the safe handling and disposal of asbestos-containing materials. Factors such as the need for containment measures, protective gear, or environmental assessments can contribute to additional expenses.


Replacing an asbestos garage roof in London demands careful consideration of costs and safety measures.
