Shingle Roofers provides professional asbestos encapsulation services across Auckland, Northland, Tauranga, Waikato, and Christchurch. When full removal isn't immediately necessary or practical, encapsulation the process of sealing asbestos materials with a specialist coating is a recognised, cost-effective management approach under New Zealand's Health and Safety at Work (Asbestos) Regulations 2016.
In Plain English
Encapsulation means sealing asbestos in place rather than removing it. If your asbestos roof is in good condition not cracked, spalling, or disturbed and you don't plan to do work that would disturb it, encapsulation can buy you significant time at a fraction of the cost of removal. We clean it, treat it, and seal it with a specialist coating. It's all documented and fully compliant with NZ law.
Encapsulation vs Removal Which Is Right for You?
The choice between encapsulation and removal depends on the condition of the asbestos material, your future plans for the property, and the risk assessment findings. Shingle Roofers will assess your specific situation and give you honest, straightforward advice:
Encapsulation May Be Appropriate When:
- Asbestos is non-friable (bonded, Class B)
- Material is in good, stable condition
- No planned work will disturb it
- Accessible for periodic inspection
Removal Is Required When:
- Material is damaged, cracked, or spalling
- Asbestos is friable (Class A)
- Future renovation will disturb the material
- Roof has reached end of serviceable life
Our Asbestos Encapsulation Process
Shingle Roofers follows a rigorous process for asbestos encapsulation that meets WorkSafe NZ requirements and the Health and Safety at Work (Asbestos) Regulations 2016:
- Risk assessment and survey: Confirm the asbestos type, condition, and suitability for encapsulation.
- Asbestos Management Plan: Document the findings and proposed encapsulation approach.
- Surface preparation: Thorough cleaning to remove moss, lichen, dirt, and any loose material using wet methods to suppress dust and fibre release.
- Penetrating primer application: A specialist primer is applied to consolidate the asbestos surface and prepare for the encapsulant.
- Encapsulant coating: Application of a specialist encapsulant that penetrates and seals the asbestos fibres, creating a protective barrier.
- Documentation: Updated Asbestos Register entry, photograph record, and maintenance schedule.
NZ Regulatory Requirements for Asbestos Encapsulation
Under the Health and Safety at Work (Asbestos) Regulations 2016, any work on asbestos material including encapsulation must be managed appropriately. WorkSafe NZ recognises encapsulation as a valid management strategy when carried out correctly and documented in an Asbestos Management Plan. Visit WorkSafe NZ ↗ for full guidance.
Importantly, encapsulation is a management approach, not a permanent solution. The Asbestos Management Plan must include a monitoring and inspection schedule, and the asbestos will ultimately need to be removed when the building is demolished, significantly altered, or when the material reaches end of life.
Did You Know?
Asbestos encapsulation, when properly carried out on stable non-friable asbestos, is recognised by WorkSafe NZ as a compliant and cost-effective alternative to full removal in many situations. It can reduce immediate costs by 30–60% while keeping the property fully compliant but it requires professional assessment to determine if it's right for your situation.
Did You Know You May Be Able to Claim This on Insurance?
If your asbestos roof has been damaged by a storm or insurable event and encapsulation is part of the repair strategy, costs may be claimable on your home insurance. Shingle Roofers will help you navigate the NZ insurance process, including EQCover for natural disaster damage.
