The corrugated grey sheets on the garage roof, the flat panels over the lean-to, the profiled cladding on the farm building — a significant proportion of the UK's non-domestic and ancillary building stock still carries asbestos cement roofing installed before 1999, when all asbestos products were banned in Britain. For most of the twentieth century, asbestos cement was the standard solution for agricultural, industrial, and outbuilding roofing. It was cheap, durable, and widely available. Now, after decades of weathering, a great deal of it is reaching the end of its useful life — and the people who own it need to know exactly what they are dealing with.
The most important thing to understand is that asbestos cement roofing is not the same as the highly dangerous sprayed asbestos insulation or pipe lagging that dominates public perception of asbestos hazard. Asbestos cement is a lower-risk, non-licensed material where the fibres are bound within a cement matrix and only become hazardous when the material is broken or handled in ways that release them. This does not mean it can be handled carelessly — asbestos fibres cause mesothelioma and lung cancer with no safe exposure threshold — but it does mean that the removal is regulated differently, costs considerably less than licensed asbestos work, and can be undertaken by a competent contractor who is not necessarily HSE-licensed.
This guide covers everything you need to know as an owner or as a roofing contractor who encounters asbestos cement on site: what the regulations require, who can legally do the work, what safe methods look like, how disposal works, what it costs, and what replacement options are available once the asbestos is gone.
Identifying asbestos cement roofing
Not all old grey roofing sheets are asbestos cement. Fibre cement products — which look nearly identical — have been manufactured without asbestos since the early 1990s and are not hazardous. Age and visual inspection alone cannot definitively confirm the presence of asbestos; laboratory analysis of a small sample is the only conclusive method.
Age as a primary indicator
Roofing materials installed before 2000 on agricultural, industrial, or domestic outbuildings should be treated as potentially containing asbestos until confirmed otherwise. Buildings constructed or roofed in the 1940s–1980s represent the highest probability period for asbestos cement use. Post-2000 profiled sheeting is almost certainly asbestos-free fibre cement.
Visual indicators (not conclusive)
Asbestos cement typically has a grey-brown or buff colour when weathered, a slightly crystalline or striated surface texture visible on broken edges, and a dull matte finish. Modern fibre cement is usually cleaner and more uniform in colour. Products from the 1970s–1980s often have visible surface weathering and a slight bluish-grey tint on the underside. Visual assessment is not reliable — test if in doubt.
Sampling and laboratory analysis
A small sample (approximately 1cm²) taken from an inconspicuous edge with minimal dust generation can be sent to a UKAS-accredited laboratory for polarised light microscopy (PLM) analysis, confirming whether asbestos fibres are present and their type. Analysis typically costs £25–£60 per sample with a 2–5 day turnaround. Many asbestos surveying companies offer sample collection and analysis as a combined service for £80–£150 per location.
Asbestos surveys for commercial premises
For non-domestic buildings, the duty to manage asbestos under Regulation 4 of CAR 2012 requires the duty holder (owner or occupier responsible for maintenance) to identify asbestos-containing materials in a management survey, assess their condition, and put a management plan in place. A management survey by a qualified asbestos surveyor typically costs £150–£400 for a small commercial building and is the starting point for any planned removal programme.
Licensed, notifiable non-licensed, and non-licensed: which category applies?
The Control of Asbestos Regulations 2012 divide asbestos work into three categories based on risk level. The category determines who can do the work, what notifications are required, and what controls must be in place. Understanding which category applies to asbestos cement roofing is essential for contractors and building owners alike.
Highest risk — HSE licence required
Required for: sprayed asbestos coatings, asbestos insulation lagging on pipes and boilers, asbestos insulating board (AIB) in some conditions. These materials release fibres readily when disturbed. Not applicable to most roofing scenarios. Requires HSE asbestos licence, health surveillance, air monitoring, and notification 14 days before work starts.
Medium risk — notification required
Applies to: asbestos cement in poor or damaged condition, or where removal methods unavoidably cause significant breakage. No HSE licence needed but: must notify the relevant enforcing authority (HSE or local authority) before starting; medical examinations required for workers; records kept for 40 years. Asbestos cement removal that cannot be done without significant breakage falls here.
Lowest risk — no licence needed
Applies to: asbestos cement in good condition removed using controlled methods that keep sheets substantially intact. No HSE licence, no pre-notification. Workers must have appropriate training and awareness (Regulation 10 asbestos awareness), suitable RPE and PPE, and a method statement. Waste must still go to a licensed hazardous waste facility.
Almost always non-licensed work
Sound asbestos cement roofing on a domestic garage, agricultural building, or light industrial unit where the sheets can be removed whole or in large pieces using controlled methods is non-licensed work. This is the most common scenario. The category escalates to NNLW if the material is heavily weathered, friable, or must be broken for removal — in which case notify the HSE before starting.
What the regulations require for non-licensed asbestos cement removal
Even though non-licensed asbestos cement removal does not require an HSE licence or pre-job notification to the HSE, it is not unregulated. The Control of Asbestos Regulations 2012 still impose specific duties on the contractor and the person commissioning the work.
Safe removal methods: how asbestos cement roofing is taken down
The principle of asbestos cement removal is to minimise fibre release by avoiding breaking the material. The controlled removal method keeps sheets as whole as possible, using tools and techniques that do not generate dust and disposing of waste immediately in sealed bags or wrapping without any further breaking.
-
1Establish the exclusion zone and decontamination arrangements
The work area below and adjacent to the roof is cordoned off to prevent third-party access. Dust sheets or polythene sheeting is laid on the ground below the roof to catch any fragments. A decontamination station — a clean changing area with a wet wipe decontamination point — is set up at the site boundary. Bystanders, including neighbouring property occupants, are kept clear of the exclusion zone throughout.
-
2Operatives don PPE and RPE before approaching the work
Full disposable Type 5/6 coveralls are put on over work clothing, including hood and elasticated cuffs. P3 half-mask respirators (minimum FFP3 disposable) are fitted and face-fit tested for the operative wearing them. Safety boots with disposable overshoes. Safety helmet if working at height. Once donned, operatives do not remove RPE until back in the clean zone and decontaminated.
⚠️ RPE selection mattersA standard dust mask or FFP2 is not adequate for asbestos work. The minimum respiratory protection for non-licensed asbestos cement work is FFP3 disposable half-mask. An elastomeric half-mask with P3 filter cartridges provides better protection and reusability. Full-face P3 masks are used for NNLW and conditions where eye protection from dust is also needed. Confirm the specific RPE with your risk assessment.
-
3Dampen the sheets immediately before removal (shadow vacuuming)
Lightly dampen the surface of the asbestos cement sheets with a fine water mist or PVA solution immediately before removal. This suppresses any surface dust from weathered material. Do not flood the sheets — excessive water adds weight and can cause sheets to break during handling. The dampening is a dust suppression measure, not a decontamination.
-
4Remove fixings carefully — do not drill or angle-grind
Asbestos cement sheets are typically fixed with hook bolts through pre-drilled holes in the purlin or rafter. Remove fixing nuts by hand or with a spanner. Do not use power tools to cut or drill through the sheets — this generates asbestos dust. Where fixings are corroded and cannot be unscrewed, cut the bolt below the nut using a junior hacksaw or bolt cutters, which generates minimal dust from the bolt rather than from the sheet.
-
5Lower sheets to ground level intact — do not throw or drop
Sheets are passed down or lowered using a rope or mechanical handling system. They must not be thrown from the roof — sheet breakage on impact is the primary source of fibre release during asbestos cement removal. Two operatives — one on the roof passing the sheet, one at ground level receiving it — is the standard approach for corrugated sheet work. Large flat panels may require mechanical assistance.
-
6Wrap and bag immediately at ground level
Sheets received at ground level are immediately wrapped in heavy-duty polythene sheeting (minimum 1000 gauge) or placed in rigid asbestos waste bags and sealed. Any broken fragments are brushed (never vacuumed with a standard vacuum — H-class HEPA vacuum only) into double-bagged red asbestos waste sacks and sealed. Labels identifying the contents as asbestos-containing waste are applied before the material leaves the immediate work area.
-
7Decontaminate operatives and clean the work area
On completion, the work area is visually cleared of all asbestos material and fragments. Operatives remove coveralls by peeling inward (to avoid self-contamination), disposing of them in asbestos waste bags. RPE is wiped down before removal. Any polythene sheeting used on the ground to catch fragments is folded inward, sealed, and added to the asbestos waste stream. The site should be visually clear before operatives leave the work area.
-
8Transport and dispose at a licensed hazardous waste facility
Packaged asbestos waste is loaded onto the contractor's vehicle with a hazardous waste consignment note. The waste is taken directly to a licensed hazardous waste facility authorised to accept asbestos. The consignment note is signed at delivery, one copy retained by the contractor and one retained by the disposal site. Copies must be kept for three years. Asbestos waste cannot be mixed with general construction skip waste.
✅ Find a licensed asbestos waste disposal siteUse the Environment Agency's public register (Environment Agency Waste Facilities search) or the relevant devolved authority (SEPA in Scotland, NRW in Wales, NIEA in Northern Ireland) to find licensed asbestos hazardous waste disposal facilities near you. Some local authority household waste recycling centres also accept small quantities of domestic asbestos cement in sealed bags — check your local council website before attempting this route.
Asbestos roof removal costs in the UK: what to expect
Non-licensed asbestos cement removal is priced at roughly £10–£30 per square metre for removal and disposal combined, with a minimum charge of £300–£500 reflecting the mobilisation, PPE, and disposal costs that exist regardless of job size. The per-square-metre cost reduces significantly for larger areas.
What drives the cost up or down
Roof height and access
A low-profile single-storey garage is the simplest and cheapest scenario. A high-eaves agricultural building requiring scaffold towers or a MEWP (mobile elevated work platform) adds significant cost for the access equipment. Anything above 4–5 metres typically requires a MEWP hire at £150–£400/day on top of the removal cost.
Condition of the material
Sound, intact sheets that can be removed whole are the least expensive scenario. Heavily weathered, friable, or already partially broken sheets require more controlled handling, more PPE, potentially upgrading to NNLW, and more waste packaging. Condition assessment before quoting is essential — the condition of the material significantly affects the method and therefore the price.
Distance to licensed disposal facility
Asbestos waste must be taken to a licensed hazardous waste facility. If there is no licensed facility within reasonable transport distance, the disposal element of the cost increases. Some rural areas in Scotland and Wales have limited licensed disposal capacity, which can push up the overall cost of even a small removal job.
Urgency and site constraints
Urgent removal — following storm damage that has broken the sheets — carries a premium for emergency mobilisation and for the upgraded PPE and controls needed when the material is already damaged. Restricted access sites (narrow entrances, overhead power lines, adjacent occupied buildings) also add cost and time to the job.
After the asbestos is removed: replacement roofing options
Once the asbestos cement is gone, the purlins, rafters, or steel frame beneath it are exposed and ready for a new roof covering. The choice of replacement material depends on the building type, structural condition, span, and budget.
Fibre cement profiled sheeting
Fibre cement corrugated or profile sheeting is the direct modern replacement for asbestos cement — it uses the same fixing system, fits the same purlin spacings, and looks nearly identical. It is asbestos-free, significantly lighter than asbestos cement, has a design life of 25–50 years, and requires no special handling or disposal. It is the default choice for agricultural and industrial building re-roofing after asbestos removal.
Typical cost installed: £15–£30 per m² depending on profile and specification, on top of the asbestos removal cost.
Metal roofing — steel or aluminium profiled sheets
Coated steel or aluminium profiled roofing sheets are the premium replacement for large-span roofs. They offer longer design life (30–40+ years), better thermal performance with insulated composite panels, and a cleaner modern appearance. Composite insulated panels are a single-operation installation combining the structural sheet and insulation layer, making them particularly efficient for agricultural and commercial re-roofing.
Typical cost installed: £25–£55 per m² for standard profiled steel; £40–£80 per m² for composite insulated panels.
Felt, EPDM, or GRP flat roof (domestic garages)
Many domestic garages with asbestos cement pitched roofs are converted to modern flat roofs as part of the removal project, where the pitch and rafter structure is simplified to a flat timber deck carrying a modern single-ply or GRP membrane. This is particularly common where the original pitched asbestos cement roof is in poor structural condition and a complete rebuild is more cost-effective than retaining the existing timber frame. A GRP or EPDM flat roof on a domestic garage has a 25–30 year design life and can be installed in a day.
Typical cost installed (flat roof on a single garage): £800–£1,800 depending on system and specification.
Finding a competent contractor: what to look for
Because non-licensed asbestos cement removal does not require an HSE asbestos licence, the market includes both specialist asbestos removal companies and competent roofing contractors who are trained and equipped for the work. Both are legitimate options for non-licensed work — what matters is the contractor's demonstrated competence, not their licence category.
- Written method statement and risk assessment specific to your job before starting
- Evidence of asbestos awareness training (minimum Category A — UKATA or equivalent) for all operatives on site
- Correct RPE (P3 half-mask or better) and disposable coveralls — and evidence they are properly used and fitted
- A clear plan for disposal including the name of the licensed waste facility
- A hazardous waste consignment note provided to you at completion
- Public liability insurance that covers asbestos work
- A fixed price that explicitly includes asbestos disposal, not just removal
- No method statement or risk assessment — "we've done loads of these, it'll be fine"
- No mention of PPE or RPE — or operative wearing only a standard dust mask
- Quote that does not include disposal or mentions "taking it to the tip"
- Offering to dispose of it in their general construction skip
- Cannot provide insurance certificate that covers asbestos work
- Significantly below-market pricing — usually indicates corners being cut on PPE, methods, or disposal
- No consignment note or documentation offered at completion
Additional requirements for non-domestic premises
The duty to manage asbestos under Regulation 4 of CAR 2012 applies to non-domestic premises. This means:
- The building owner or occupier responsible for maintenance (the duty holder) must have a current asbestos management survey identifying the location and condition of all asbestos-containing materials
- Before any planned removal, a refurbishment and demolition (R&D) asbestos survey is required to identify all ACMs in the areas to be disturbed — a management survey alone is not sufficient for planned removal work
- A pre-tender asbestos report must be provided to any contractor who will work in or on the building where asbestos is present
- The completion of asbestos removal must be recorded in the building's asbestos register, confirming the material has been removed from that location
- For notifiable non-licensed work and above, the responsible person must ensure worker health surveillance records are maintained for 40 years
Does asbestos roof removal require planning permission?
The removal of asbestos cement roofing from an existing building does not in itself require planning permission — maintenance and repair work on an existing roof generally falls within the owner's rights without planning consent. However, the replacement roofing may require planning consideration in specific circumstances:
- Listed buildings: Any alteration to a listed building, including roof material change, requires Listed Building Consent regardless of whether the material was previously asbestos cement. Consent must be obtained before works begin.
- Conservation areas: Changing the visible roof material (colour, profile, or texture) on a property in a Conservation Area may require planning permission if it materially affects the appearance of the building. Check with your local planning authority before specifying a replacement material that differs significantly from the existing profile.
- Agricultural buildings: Permitted development rights under Class Q and Class R of the Town and Country Planning (General Permitted Development) Order cover certain agricultural building alterations. Large-scale re-roofing of agricultural buildings usually falls within PD rights, but confirm with the Local Planning Authority if the building size or use is complex.
- Change of roof form: If the asbestos removal is combined with a structural change to the roof (e.g. converting a pitched asbestos roof to a flat replacement), the change of form may require planning permission depending on the building type and location.

Frequently Asked Questions
Do I need a licensed contractor to remove asbestos roofing in the UK?
It depends on the type and condition of the asbestos. Asbestos cement roofing sheets in good condition are non-licensed asbestos material — they do not require an HSE-licensed contractor to remove, but the work must be carried out safely with appropriate PPE, controlled methods to minimise fibre release, and disposal to a licensed asbestos waste site. If the asbestos cement is significantly damaged or friable, it may escalate to notifiable non-licensed work requiring notification to the HSE before starting. Sprayed asbestos and pipe lagging are licensed materials requiring an HSE-licensed contractor.
Is asbestos cement roofing dangerous?
Asbestos cement in good, undamaged condition presents a very low risk to health because the fibres are bound within the cement matrix and cannot be easily inhaled. The danger arises when the material is broken, drilled, cut, or handled in ways that release fibres into the air. Weathered asbestos cement that is friable poses a higher risk. During removal, controlled methods that keep sheets whole, use water suppression, and avoid power tools significantly reduce fibre release. There is no safe level of asbestos fibre exposure — controlled methods are essential even for low-risk materials.
How much does asbestos roof removal cost in the UK?
Asbestos cement roof removal in the UK typically costs £10–£30 per square metre for removal and disposal combined, with a minimum charge of £300–£500 for small jobs. A single-car garage with approximately 25–30m² typically costs £400–£900 all in. A large agricultural building of 500m² may cost £5,000–£15,000 depending on access, material condition, and disposal volumes. Licensed asbestos removal for higher-risk materials costs substantially more — typically £50–£150 per square metre plus containment and air monitoring costs.
Can I remove asbestos roofing myself?
Householders in England, Wales, and Scotland are not legally prohibited from removing small quantities of asbestos cement from their own domestic property provided it is non-licensed work, the material is in reasonable condition, they use appropriate RPE (FFP3 minimum), disposable coveralls, and dispose of the waste correctly at a licensed facility. However, most professionals advise against DIY removal given the health stakes and the relatively modest cost difference between self-removal and a competent contractor. Commercial buildings and landlord-owned property are subject to Control of Asbestos Regulations 2012 requirements that make professional removal effectively mandatory.
How do I dispose of asbestos roofing waste in the UK?
Asbestos waste is classified as hazardous waste and cannot be placed in general skips, household waste, or recycling. It must be double-bagged in heavy-duty red asbestos waste bags, labelled with the correct asbestos hazard label, and taken to a licensed asbestos waste disposal site with a hazardous waste consignment note. Some local authority household waste recycling centres accept small quantities of domestic asbestos cement in sealed bags — check your local council website. Licensed contractor-collected waste is transferred directly to licensed disposal facilities with a full consignment note audit trail.
How do I find a reputable asbestos removal contractor in the UK?
For non-licensed asbestos cement work, look for roofing contractors who can provide: a written method statement and risk assessment for your specific job; evidence of asbestos awareness training for all operatives; appropriate RPE (P3 half-mask or better) and disposable coveralls; a named licensed waste disposal facility; and public liability insurance covering asbestos work. For licensed work, verify the contractor's HSE asbestos licence on the public register at hse.gov.uk. Be cautious of quotes significantly below market rate or contractors who do not mention PPE, method statements, or consignment notes unprompted.
Don't let an asbestos roof become a long-term liability
Weathering asbestos cement eventually reaches a point where it becomes progressively more hazardous and more expensive to remove. Getting it done now — while it is still in manageable condition — is both the safest and the most cost-effective approach.
