A Guide to Overcladding Asbestos in Buildings

If you own or manage a building with an asbestos roof, you may be considering your options for dealing with this potentially hazardous material. 

One solution is overcladding, which involves installing a new roof or wall cladding system over the existing asbestos. 

In this article, we’ll explore what overcladding is, its benefits and how AT Bone & Sons can help with your asbestos overcladding needs in Buckinghamshire, Hertfordshire and Bedfordshire.

What is Overcladding?

Overcladding is the process of installing a new roof or wall cladding system over an existing structure, such as an asbestos roof. This method captures the asbestos, preventing the release of harmful fibres into the environment. 

Overcladding is an effective way to manage asbestos without the need for complete removal and rebuilding.

The Benefits of Overcladding Rather Than Remove and Rebuild

There are several advantages to choosing overcladding over removing and rebuilding an asbestos roof:

1. Cost-effective: Overcladding is generally less expensive than a complete removal and rebuild, as it requires less labour and materials.
2. Thermal efficiency: Modern cladding systems can improve the thermal efficiency of your building, reducing energy costs and enhancing comfort for occupants.
3. Strength: Overcladding can add structural strength to your building, helping to protect against weather damage and extend the life of your roof.

When is Overcladding Needed and How Can It Help?

Overcladding is an ideal solution when an asbestos roof is in poor condition or poses a health risk due to the release of asbestos fibres. By encapsulating the asbestos, overcladding helps to:

1. Prevent asbestos exposure to building occupants and the surrounding environment
2. Extend the life of the roof by protecting it from weather damage
3. Improve the appearance of the building with a modern, attractive finish

What is Asbestos?

Asbestos is a naturally occurring mineral that was widely used in construction materials between the 1950s and 1980s due to its strength, durability and heat-resistant properties. However, it was later discovered that asbestos fibres can cause serious health problems when inhaled, including lung cancer and mesothelioma.

The Risks and Dangers of Asbestos

When asbestos-containing materials are damaged or disturbed, tiny fibres can be released into the air and inhaled. Over time, this can lead to severe health issues, such as:

• Asbestosis: A chronic lung disease caused by scarring of the lung tissue
• Lung cancer: A malignant tumour that develops in the lungs
• Mesothelioma: A rare and aggressive cancer that affects the lining of the lungs, chest or abdomen

How is Overcladding Carried Out?

Overcladding an asbestos roof typically involves the following steps:

1. Inspection: A thorough survey of the existing roof is conducted to assess its condition and determine the best cladding system for the job.
2. Preparation: The roof surface is cleaned and prepared for the installation of the new cladding system.
3. Installation: The new cladding system, which may include insulation and weatherproofing layers, is installed over the existing asbestos roof.
4. Finishing: Any necessary flashings, trims or sealants are applied to ensure a weathertight and attractive finish.
