Asbestos Siding Shingles: What Every UK Homeowner Needs to Know
If your home was built before the 1980s, there is a real chance it contains asbestos — and one of the most overlooked locations is the exterior cladding. Asbestos siding shingles were widely used across the UK as a durable, fire-resistant cladding material, and millions of properties still have them in place today. The problem is that most homeowners have no idea they are living with them.
This post covers everything you need to know: what asbestos siding shingles look like, where else asbestos hides in older homes, the health risks involved, and what you should do before touching a single tile during a renovation.
What Are Asbestos Siding Shingles?
Asbestos siding shingles are flat or corrugated panels used to clad the exterior walls of homes. They were manufactured by mixing chrysotile (white asbestos) with cement, creating a material known as asbestos cement — sometimes called AC sheet or Eternit board.
The appeal was obvious at the time. Asbestos cement was cheap, lightweight, weatherproof, and fire-resistant. Builders and architects favoured it throughout the mid-twentieth century for everything from roof tiles to wall panels. Its use was so widespread that identifying which properties contain it has become a significant challenge for surveyors and homeowners alike.
How to Identify Asbestos Siding Shingles
Visually identifying asbestos siding shingles is not straightforward — you cannot confirm the presence of asbestos by sight alone. However, there are tell-tale signs that should put you on alert:
- Flat or corrugated cement-like panels on external walls
- A slightly rough, chalky surface texture
- Panels that are grey, white, or occasionally green-tinged
- Shingles that overlap in a fish-scale or rectangular pattern
- Visible weathering, cracking, or surface erosion on older panels
- A brittle appearance, particularly on panels more than 40 years old
If your home was built or re-clad between the 1930s and the late 1990s, and you can see cement-based shingles or panels on the exterior, treat them as suspect until proven otherwise. The only way to confirm the presence of asbestos is through professional asbestos testing.
Why Asbestos Siding Shingles Are Still a Problem Today
Many homeowners assume that because asbestos cement is a bonded material — meaning the fibres are locked within the cement matrix — it is safe to leave alone. In good condition, that is broadly true. The fibres are not freely airborne when the material is intact.
The danger begins the moment the material is disturbed, damaged, or starts to degrade. Weathering, impact damage, drilling, cutting, or sanding can all release asbestos fibres into the air. Once airborne, those fibres can be inhaled, and it is inhalation that causes the serious diseases associated with asbestos exposure.
The Condition of the Material Matters
Surveyors assess asbestos-containing materials using a condition rating system. Materials in good condition with no visible damage are considered lower risk. Materials that are crumbling, cracked, or heavily weathered are rated as higher priority for action.
For asbestos siding shingles, this means a property that has had no maintenance work for decades may have panels that are far more hazardous than they appear from the ground. A professional survey will assess the condition of every panel and give you a clear risk rating.
The Health Risks You Cannot Ignore
Asbestos is the single largest cause of work-related deaths in the UK. The diseases it causes — mesothelioma, asbestosis, and asbestos-related lung cancer — typically take decades to develop, which is why so many people underestimate the risk.
There is no safe level of asbestos exposure. Mesothelioma, a cancer of the lining of the lungs, is almost exclusively caused by asbestos exposure. The UK has one of the highest rates of mesothelioma in the world, a direct legacy of the widespread use of asbestos in construction throughout the twentieth century.
Disturbing asbestos siding shingles without proper precautions — even during what seems like a minor repair — puts you, your family, and any tradespeople on site at serious risk. This is not a situation where common sense alone is sufficient protection.
Other Common Locations of Asbestos in Older Homes
Asbestos siding shingles are just one of many places asbestos can lurk in a pre-1980s property. Before any renovation work, it pays to understand the full picture of where asbestos-containing materials (ACMs) are commonly found.
Roof Tiles and Roofing Materials
Asbestos cement was used extensively in roofing. Corrugated roof sheets on garages, outbuildings, and lean-tos are among the most common ACMs found in residential properties. Flat roof tiles and ridge capping may also contain asbestos.
Attics and Pipe Insulation
Loose-fill insulation in attics — particularly vermiculite insulation — may contain asbestos fibres. Pipe lagging around older central heating systems and hot water pipes was also routinely made from asbestos-based materials. Disturbing this insulation during loft conversions or boiler replacements is a significant exposure risk.
Vinyl Floor Tiles and Adhesives
Vinyl floor tiles manufactured before the 1980s frequently contained asbestos fibres, as did the black bitumen adhesives used to fix them. If your property has original vinyl flooring that has never been replaced, there is a reasonable chance it contains asbestos. Sanding, scraping, or lifting these tiles without testing first is dangerous.
Textured Coatings and Artex Ceilings
Artex and similar textured coatings applied to ceilings and walls before the mid-1980s often contained chrysotile asbestos. Scraping or sanding these surfaces — a common task during decorating — can release fibres. If you have a heavily textured ceiling in an older property, get it tested before you touch it.
Partition Walls, Boards, and Ceiling Tiles
Asbestos insulating board (AIB) was used in partition walls, ceiling tiles, fire doors, and around boilers and fireplaces. AIB is considered a higher-risk material than asbestos cement because the fibres are less tightly bound and more readily released when disturbed.
Sheds, Garages, and Outbuildings
Older sheds and garages are frequently clad or roofed with asbestos cement sheets. These are often in poor condition, with cracked or weathered panels that pose a greater risk than intact materials. If you are demolishing or renovating an outbuilding, always arrange a professional survey first.
Drainpipes, Guttering, and Cooker Canopies
Some older rainwater goods — guttering, downpipes, and soil pipes — were manufactured using asbestos cement. Certain cooker hoods and canopies also contained asbestos as a heat-resistant component. These are easy to overlook but should be assessed as part of any thorough survey.
What to Do If You Suspect Asbestos Siding Shingles or Other ACMs
The golden rule with any suspected asbestos-containing material is simple: do not disturb it until you know what you are dealing with. Here is a practical step-by-step approach:
- Stop work immediately — if you have already started and suspect you may have disturbed asbestos, stop, leave the area, and keep others out.
- Do not attempt to clean up — ordinary vacuum cleaners and household cleaning equipment will spread fibres rather than contain them.
- Arrange professional asbestos testing — a UKAS-accredited laboratory can analyse samples to confirm whether asbestos is present. Our asbestos testing service covers the full range of materials found in residential and commercial properties.
- Commission the right survey — an management survey identifies ACMs in their current condition; a refurbishment survey is required before any intrusive work begins.
- Follow professional advice on management or removal — not all asbestos needs to be removed. In many cases, encapsulation or management in situ is the appropriate course of action.
Legal Requirements and the Control of Asbestos Regulations
The Control of Asbestos Regulations set out clear duties for those who manage buildings and for anyone carrying out work that may disturb asbestos. These regulations apply to non-domestic premises and to the common parts of residential buildings, but the principles of safe management are equally relevant to homeowners undertaking renovation work.
Under these regulations, anyone who may come into contact with asbestos during their work — including tradespeople such as electricians, plumbers, and builders — must have received appropriate asbestos awareness training. Employers and contractors have a duty not to expose workers to asbestos fibres.
Licensed vs Non-Licensed Work
Not all asbestos removal requires a licensed contractor, but higher-risk materials — including asbestos insulating board and any work likely to disturb significant quantities of fibres — must be carried out by a contractor licensed by the Health and Safety Executive (HSE). Asbestos cement work, including the removal of asbestos siding shingles, may fall under notifiable non-licensed work (NNLW) depending on the scope and conditions. Always seek professional advice before proceeding.
The HSE’s guidance document HSG264 provides detailed information on surveying and sampling, and the HSE website is the definitive source for current regulatory requirements.
Disposal of Asbestos Waste
Asbestos waste is classified as hazardous waste under UK law. It must be double-bagged in clearly labelled asbestos waste sacks, transported by a licensed waste carrier, and disposed of at a licensed facility. It cannot be placed in general household waste or a skip.
Failure to comply with waste regulations can result in significant fines. This is another reason why engaging a professional asbestos removal contractor is essential — they handle all aspects of safe disposal as part of the job.
When Asbestos Siding Shingles Need to Be Removed
Not every property with asbestos siding shingles requires immediate removal. If the material is in good condition — no cracking, no surface erosion, no physical damage — a managed approach is often the safest and most practical option. This means regular monitoring, keeping records, and ensuring no work is carried out on the material without proper precautions.
Removal becomes necessary when the material is significantly deteriorated, when renovation or demolition work will disturb it, or when the property is being sold and a buyer requires it. In all cases, professional removal by a qualified contractor is the only safe route.
If a full demolition is planned, a demolition survey must be completed before any work begins. This is a legal requirement, not a recommendation.
Asbestos Surveys: Getting the Right Assessment for Your Property
The only reliable way to establish whether your home contains asbestos siding shingles or any other ACMs is a professional asbestos survey carried out by a qualified surveyor. At Supernova Asbestos Surveys, our surveyors are trained to RSPH/BOHS P402 standard and work in accordance with HSG264 guidance. We cover the whole of the UK.
If you are based in the capital, our asbestos survey London service provides rapid response for both residential and commercial clients. In the North West, our asbestos survey Manchester team covers the city and surrounding areas. And for properties in the Midlands, our asbestos survey Birmingham service delivers the same high standard of assessment.
What a Survey Involves
A surveyor will carry out a thorough inspection of the property, taking bulk samples from any materials suspected of containing asbestos. Those samples are sent to a UKAS-accredited laboratory for analysis.
You will receive a written report detailing every ACM identified, its condition, its risk rating, and recommended action. This report is essential before any renovation, sale, or refurbishment work begins. It protects you legally, protects any contractors on site, and gives you a clear plan for managing or removing any hazardous materials found.
Protecting Your Home, Your Family, and Anyone Who Works on Your Property
Asbestos siding shingles are not a relic of the past that only affects derelict industrial buildings. They are present on ordinary homes across the UK right now, on streets in every town and city. Many of those homes are being renovated, extended, or re-clad without any testing having taken place.
The consequences of getting this wrong are serious. Asbestos-related diseases are irreversible. There is no treatment that undoes the damage caused by inhaled asbestos fibres. The only protection is prevention — knowing what you are dealing with before work begins, and ensuring that any disturbance is managed by qualified professionals.
If your property was built before the year 2000 and you are planning any work that could affect the exterior cladding, roof, internal walls, floors, or ceiling — commission a survey first. It is the single most important step you can take to protect everyone involved.
Frequently Asked Questions
How do I know if my home has asbestos siding shingles?
If your home was built or re-clad between the 1930s and the late 1990s and has cement-based panels on the exterior walls, there is a possibility they contain asbestos. Visual inspection alone cannot confirm this. The only reliable method is professional asbestos testing, where a sample is taken and analysed by a UKAS-accredited laboratory.
Are asbestos siding shingles dangerous if left undisturbed?
Asbestos cement in good condition — with no cracking, surface erosion, or physical damage — poses a lower risk because the fibres are bound within the cement matrix. The danger arises when the material is disturbed, damaged, or deteriorates to the point where fibres can become airborne. Regular monitoring and a managed approach are appropriate for intact materials.
Do I need a licensed contractor to remove asbestos siding shingles?
Asbestos cement, including asbestos siding shingles, does not always require a licensed contractor for removal, but the work may fall under notifiable non-licensed work (NNLW) depending on the scale and conditions involved. Higher-risk materials such as asbestos insulating board do require a licensed contractor. Always seek professional advice before starting any removal work.
Can I dispose of asbestos siding shingles in a skip or household bin?
No. Asbestos waste is classified as hazardous waste under UK law and must be double-bagged in labelled asbestos waste sacks, transported by a licensed waste carrier, and disposed of at a licensed facility. Placing asbestos waste in a general skip or household bin is illegal and can result in significant fines.
What type of asbestos survey do I need before renovating my home?
If you are planning any intrusive renovation work — including re-cladding, loft conversion, structural alterations, or demolition — you will need a refurbishment or demolition survey rather than a standard management survey. A management survey is appropriate for monitoring ACMs in their current state, but it is not sufficient before work that will disturb the fabric of the building begins.
