Asbestos removal Kenya explained: NEMA requirements, licensed asbestos contractors, safe removal procedures and how asbestos disposal is documented.
Asbestos removal in Kenya requires more than taking old roofing sheets off a building. Suspected asbestos roofing should be assessed, handled, transported and disposed of through an appropriate controlled process, with environmental and occupational safety requirements considered before work begins.
Older buildings may contain asbestos cement roofing because asbestos was historically used as reinforcement in cement products. When these sheets remain intact, the risk profile is different from situations where they are being cut, broken, demolished or removed.
The important point for property owners is that asbestos removal should not be treated like ordinary mabati replacement.

If you are planning to remove an old roof that may contain asbestos, establish what the material is, obtain the appropriate professional advice and confirm the current requirements that apply to the project before disturbing it.
What Is Asbestos Roof Removal?
Asbestos roof removal is the controlled dismantling and management of roofing materials that contain or are suspected of containing asbestos, with measures taken to prevent unnecessary fibre release and environmental contamination.
The process can involve:
- Identifying suspected asbestos-containing material
- Assessing its condition
- Planning the work
- Establishing a controlled work area
- Using appropriate protective measures
- Carefully removing the material
- Packaging and securing asbestos waste
- Transporting the waste appropriately
- Disposing of it at an authorised facility
- Maintaining documentation
The exact requirements depend on the circumstances, applicable Kenyan regulations and the authorities responsible for environmental and occupational safety.
Why Asbestos Removal Is Different From Normal Roofing
Asbestos-containing roofing must not be handled like ordinary iron sheets because cutting, breaking or disturbing the material can release fibres that may become airborne.
Ordinary roof replacement may involve:
- Removing screws
- Cutting sheets
- Breaking damaged materials
- Dropping sheets
- Stacking old roofing
- Loading waste onto a vehicle
These practices can be inappropriate where asbestos is involved.
The removal plan therefore needs to control how the material is accessed, dismantled, packaged and transported.
Who Should Remove Asbestos Roofing?
Property owners should use appropriately qualified and authorised professionals for asbestos-related removal rather than attempting to dismantle suspected asbestos roofing themselves.
When selecting a contractor, ask for evidence of:
- Relevant licences or approvals
- Training and competence
- Previous asbestos-related work
- Safety procedures
- Waste-management arrangements
- Transport arrangements
- Disposal arrangements
- Insurance where applicable
Do not rely only on a contractor's claim that they "know how to remove asbestos."
Ask for documentation.
What Role Does NEMA Play?
The National Environment Management Authority (NEMA) is Kenya's environmental regulator, and asbestos waste management can involve environmental requirements relating to handling, transportation and disposal.
NEMA requirements should be confirmed for the specific project because regulatory procedures can change and may depend on the type, quantity and location of the waste.
A responsible project should establish:
- Which environmental approvals or notifications apply
- How asbestos waste must be handled
- Where it may be transported
- Which disposal facility is authorised
- What records must be retained
Do not assume that ordinary construction waste procedures are sufficient for asbestos-containing material.
NEMA Asbestos Disposal Requirements
NEMA asbestos disposal requirements are intended to ensure that asbestos-containing waste does not become an uncontrolled environmental or public-health hazard.
The disposal process should be planned before the roof is removed.
This means determining:
- Where the waste will go
- How it will be contained
- How it will be transported
- Who will receive it
- What documentation will confirm disposal
The disposal destination should be appropriately authorised for the type of waste involved.
Property owners should request documentation confirming the final destination and disposal of the material.
Why Disposal Documentation Matters
Disposal records provide evidence that asbestos waste was transferred through the planned waste-management process rather than being abandoned, buried or mixed with ordinary construction debris.
Useful records may include:
- Waste transfer documentation
- Transport records
- Disposal receipts
- Facility details
- Contractor information
- Project photographs
- Work completion documentation
Keep these records with the property's renovation or construction documents.
They can be particularly useful for commercial buildings, institutional projects and property transactions.
Can Asbestos Sheets Go Into a Normal Skip?
Suspected asbestos roofing should not simply be placed into an ordinary construction-waste skip because mixing asbestos waste with general waste can create additional exposure and disposal problems.
Before removal, establish the correct waste-management route.
Do not:
- Throw sheets into an open skip
- Mix them with rubble
- Break them to save space
- Leave them beside a road
- Burn them
- Bury them casually
- Transport them without appropriate controls
The waste should remain controlled from removal through final disposal.
How Should an Asbestos Roof Be Prepared for Removal?
Preparation is one of the most important stages because controlling access and disturbance can reduce the possibility of fibre release during the removal operation.
The responsible contractor should assess:
- Roof condition
- Sheet type
- Building height
- Access routes
- Weather
- Occupants
- Nearby buildings
- Waste quantity
- Transport route
- Disposal destination
The work area should be controlled so that unauthorised people do not enter during removal.
Why the Condition of the Roof Matters
The condition of asbestos cement roofing affects the removal strategy because cracked or deteriorated sheets may be more vulnerable to breakage during handling.
Before work starts, assess whether the sheets are:
- Intact
- Cracked
- Broken
- Weathered
- Friable
- Contaminated
- Partially collapsed
A severely deteriorated roof requires particularly careful planning.
Do not walk across fragile suspected asbestos sheets simply to inspect them.
What Happens During Removal?
A properly planned asbestos removal operation aims to remove sheets carefully while minimising breakage, dust generation and unnecessary disturbance.
The exact procedure should be determined by the competent contractor and applicable requirements.
Depending on the project, this can include:
- Controlled access
- Appropriate protective equipment
- Suitable respiratory protection
- Careful dismantling
- Controlled lowering of sheets
- Secure packaging
- Controlled waste collection
The objective is to keep the material intact wherever reasonably possible and prevent uncontrolled contamination.
Why You Should Not Cut Asbestos Roofing
Cutting asbestos cement roofing can generate dust and should not be used as a routine method of dismantling suspected asbestos sheets.
Avoid:
- Angle grinders
- Circular saws
- Abrasive cutting wheels
- Drilling
- Sanding
- Mechanical breaking
These activities can significantly disturb the material.
Where fixings need to be removed, the contractor should use an appropriate method that minimises damage and follows the applicable asbestos work procedure.
What Protective Equipment Is Needed?
Asbestos removal requires appropriate personal protective equipment and respiratory protection selected according to the risk assessment and applicable requirements.
Depending on the work, controls can include:
- Protective clothing
- Gloves
- Appropriate footwear
- Respiratory protective equipment
- Eye protection where required
However, personal protective equipment is not a substitute for proper work controls.
The primary objective should be to prevent fibre release and limit exposure.
What Happens to the Removed Sheets?
Removed asbestos-containing sheets should be controlled and securely packaged so that fibres and fragments are not released during handling or transportation.
The contractor should establish an appropriate packaging and containment method before dismantling begins.
The material should not be:
- Dragged across the ground
- Broken deliberately
- Thrown from the roof
- Left uncovered
- Mixed with general waste
Careful handling protects workers, occupants and members of the public.
Transporting Asbestos Waste
Asbestos waste requires controlled transportation to prevent damage, accidental release and illegal dumping.
Before transport, establish:
- The quantity of waste
- Packaging method
- Vehicle requirements
- Transport documentation
- Disposal destination
- Emergency procedures
The route should be planned so that the waste reaches the authorised destination without unnecessary handling.
What Happens at Disposal?
The final stage is controlled disposal at an appropriate facility in accordance with applicable environmental requirements.
The contractor should be able to explain:
- Where the material will be taken.
- How it will be transported.
- Which facility will receive it.
- What documentation will be provided.
- How completion of disposal will be demonstrated.
Do not accept vague statements such as "we will dispose of it properly."
Ask for evidence.
What Should a Property Owner Ask an Asbestos Contractor?
Before hiring a contractor, ask specific questions about licensing, safety, waste transportation and disposal rather than focusing only on the removal price.
Ask:
- Are you authorised to undertake this type of work?
- How will the material be assessed?
- What safety controls will be used?
- How will the sheets be removed?
- How will the waste be packaged?
- Who will transport it?
- Where will it be disposed of?
- Is the disposal facility appropriately authorised?
- What documentation will I receive?
- How will the work area be cleared after removal?
A professional contractor should be able to provide clear answers.
How Much Does Asbestos Roof Removal Cost in Kenya?
The cost of asbestos roof removal in Kenya varies according to the size and height of the roof, material condition, access, location, labour, safety controls, transport and disposal requirements.
A quotation may need to account for:
- Site assessment
- Safety preparation
- Labour
- Access equipment
- Protective equipment
- Packaging
- Transport
- Disposal fees
- Documentation
- Replacement roofing
This is why asbestos removal should not be compared directly with ordinary mabati removal.
A very cheap quotation may not include all the controls required for responsible asbestos management.
Do Not Choose a Contractor Based Only on Price
The lowest asbestos removal quotation may not represent the safest or most compliant service because proper containment, transportation and disposal involve additional planning and costs.
When comparing quotations, check whether each one includes:
| ItemIncluded? | |
| Site assessment | Check |
| Controlled removal | Check |
| Protective equipment | Check |
| Waste packaging | Check |
| Transport | Check |
| Disposal | Check |
| Disposal documentation | Check |
| Site clean-up | Check |
| Replacement roofing | Check |
A detailed quotation makes comparisons much easier.
What If You Are Replacing the Roof With New Mabati?
Once the asbestos roof has been safely removed and the site is ready for new construction, the replacement roof can be specified according to the building's location, design and budget.
Potential replacement options can include:
- Corrugated roofing sheets
- Box profile sheets
- IT5 sheets
- Long-span sheets
- Stone-coated tiles
The appropriate choice depends on:
- Roof pitch
- Building structure
- Span
- Climate
- Appearance
- Budget
- Expected service life
Do not install new roofing materials until the old asbestos-containing material has been appropriately managed.
Choosing Replacement Roofing Sheets
Replacing an asbestos roof is an opportunity to upgrade the building's roofing specification rather than simply replacing old sheets with the cheapest available material.
Consider:
Steel Thickness
Select an appropriate thickness for the roof design and structural requirements.
Coating
Consider the building's environment, particularly in coastal areas.
Profile
Choose a profile appropriate for the roof structure and appearance.
Fasteners
Use compatible roofing screws and accessories.
Insulation
Consider insulation where thermal comfort is important.
Warranty
Understand the manufacturer's warranty conditions before purchasing.
Asbestos and Solar Panel Installation
Installing solar panels on a suspected asbestos roof should not begin until the roofing material has been appropriately assessed because drilling or fixing directly into asbestos-containing sheets can disturb the material.
Solar installers should know what roofing material they are working on before installation.
If the roof requires replacement, it may be safer to address the roofing system before installing new solar equipment.
Planning both projects together can prevent unnecessary rework.
Asbestos Roof Removal for Commercial Buildings
Commercial asbestos removal requires particularly careful planning because employees, customers, contractors and neighbouring properties may be exposed if the work is poorly controlled.
For:
- Offices
- Warehouses
- Factories
- Schools
- Hospitals
- Churches
- Shopping facilities
consider how the removal will affect normal operations.
The project may require:
- Restricted access
- Temporary relocation
- Work scheduling
- Controlled transport
- Site communication
- Documentation
What Property Owners Should Never Do
Do not attempt to save money by breaking, cutting or burning suspected asbestos roofing yourself.
Never:
- Burn asbestos sheets
- Break sheets into small pieces
- Throw them into ordinary waste
- Dump them in open areas
- Leave them beside roads
- Use an angle grinder
- Pressure-wash them
- Sell suspected asbestos sheets for reuse
If you suspect asbestos, stop and obtain appropriate professional advice.

Final Thoughts
Asbestos roof removal in Kenya should be treated as a controlled environmental and occupational safety project, not ordinary roofing work.
Before removing an older roof:
- Establish whether asbestos is suspected.
- Do not disturb the material unnecessarily.
- Use appropriately qualified and authorised professionals.
- Confirm the applicable NEMA and other regulatory requirements.
- Plan waste containment and transportation.
- Use an appropriate disposal facility.
- Obtain disposal documentation.
- Only proceed with replacement roofing once the old material has been safely managed.
Most importantly, do not allow an old asbestos roof to be broken up and mixed with ordinary construction waste simply because it is cheaper or faster.
The safest approach is to plan the entire process before work begins.
