Asbestoseal Roof Coating System by Liquasil

Not all roof coating system are equal, which is why we use Liquasil Asbestoseal, the first BBA approved asbestos roof coating system on the market. The BBA (British Board of Agrément) is one of the UK’s leading notified bodies offering approval, certification, and test services to manufacturers of products and systems supplying the construction industry. Asbestososeal is the only product that has been manufactured specifically for protecting asbestos cement roofs and is a product with a stated and tested life of at least 25 years.

Alternatives and Drawbacks

Most corrugated asbestos roofs are now past their expected life expectancy of 25-40 years, with many now starting to suffer from deterioration resulting in cracks to the sheets and corrosion to the metal fixings, causing water damage to internal structures, stock and equipment. Removal of the asbestos sheets and replacement with a new roof will be costly and unless the building is unoccupied, could also be very inconvenient. Another option is to over-sheet the roof with a modern roof but this can present it’s own issues as it may compromise the roof structure due to excess additional weight, increase the risk of disturbing the asbestos through fixing and may cause condensation issues. 

Benefits of Applying A Roof Coating System

• Cost-effective compared to replacement 

• Insurance guarantee options in addition to up to 20 years manufacturer's product warranty

• Extends the life span of the roof 

• Minimal business disruption compared to full roof replacement   

• Rejuvenates the look of your roof and can be provided in any RAL colour you wish   

• Moss and lichen are less likely to adhere to the surface   

• No building regulations to satisfy

Typical Asbestos Roof Repairs

A typical solution for fixing leaking asbestos roof and gutters is to carry out temporary, local patch repair to the roof sheets and fixings or a costly full replacement of the entire roof. ID Asbestos can provide a cost-effective, long-lasting solution. 

Asbestos Cement Roof Life Span

Asbestos cement roof sheets and gutters were expected to have a life span of between 25 and 40 years. According to the Land Registry, 55% of all industrial premises in Britain have an asbestos roof and 75% of all asbestos roofs ever installed are still in place today. It’s not surprising that a majority of asbestos roofs are now past their life expectancy and are starting to fail, with leaks causing water damage to internal structures, stock and equipment.

Asbestoseal Roof Coating System by Liquasil

Asbestoseal is the only BBA approved asbestos coating system on the market. The British Board of Agrément is one of the UK’s leading notified bodies offering approval, certification, and test services to manufacturers of products and systems supplying the construction industry. Asbestoseal is tried and tested and has proved to be one of the best products for this type of application.

Latent Defects Insurance Guarantee

Once the coating system has been applied to the roof, it’s inspected and audited by Liquasil to enable a full latent defects insurance guarantee for 10 years. This ensures the product has been applied correctly and to the thickness of the manufacturers specification and will perform exactly as expected, giving a long and extended life of the existing roof, which is expected to extend over 100 years.

Asbestos Roof Coating System Installation 

Every job is not the same and our surveyors will determine the most suitable and safest method of installation.

Health and Safety

Our first consideration is always the health and safety of our clients, their staff and visitors, the public and our own team of employees. One of ID Asbestos project managers will manage each job from start to finish. ID Asbestos will employ only the highest health and safety standards throughout the duration of the project, ensuring compliance to health and safety and asbestos regulations are adhered to at all times. All access and fall protection systems are included within the price we provide.

Asbestos Roof Cleaning

Cleaning of the roof before the application of Asbestoseal is paramount for good adhesion of the product. We use two different methods of cleaning. The HSE’s preferred method is to use a closed box system that uses high pressure water to clean the roof within the confines of a box, that reduces the high-pressure spray producing airborne asbestos fibre release. The Second method is the use of low pressure, super-heated steam, which can reach temperatures of 150˚c. The benefit of using low pressure steam is that it reduces the risk of water ingress into the property if occupied and the roof is in poor condition.

The wastewater produced will be contaminated with asbestos fibres. The water is diverted at the downpipes and into a filtration system that filters the water to 5 microns. At this point, the water is safe to re-enter the storm drain system. 

Repair, Treat and Seal fixings and Damaged Roof Sheets and Gutters

Once the roof has been cleaned, it enables our trained staff to inspect the roof for cracks and damage and either repair or replace the sheets if not repairable. All metal fixings are coated with a corrosion primer to prevent rust breaking through the new top coating and a non-sag sealer applied to the fixings and local repairs. 

Final Finish Coat

Once all preparation work has been carried out, the final Asbestoseal is then applied as the final coat to the asbestos roof sheets. Asbestoseal can be provided in any RAL colour. Once applied, the product will resist moss or lichen and retain its colour indefinitely. 

Air Monitoring

Before, during and after the project, ID Asbestos will employ an independent analyst to carry out air monitoring. This will include personal air monitoring of our employees carrying out the work, and air monitoring to the internal and external areas of the property. Undertaking air monitoring ensures that the working practices and procedures we are using, do not produce asbestos fibre release over the control limit that’s deemed acceptable by the Health and Safety Executive.
