Asbestos Decramastic Roof Removal for Homeowners: What You Need to Know

If your home has a decramastic roof installed before the 1980s, you may be dealing with asbestos. Decramastic roofs, popular in New Zealand for their durability and weather resistance, were often manufactured with asbestos, making them hazardous if disturbed. Knowing how to approach asbestos roof removal safely and legally is essential to protect your health, your family, and the surrounding environment. Here’s a complete guide for homeowners.

Why Asbestos Decramastic Roofs Are a Health Concern

Asbestos decramastic roofs contain asbestos fibers bonded within the roofing material. While intact asbestos materials are generally stable, any disturbance—whether from weather damage, renovations, or aging—can release harmful asbestos fibers into the air. Once airborne, these fibers pose severe health risks, including lung cancer, asbestosis, and mesothelioma.

Removing an asbestos decramastic roof involves strict safety procedures to prevent exposure, so it’s crucial to know the right steps and legal requirements before you start.

Step-by-Step Guide to Safe Asbestos Decramastic Roof Removal

If you suspect or know that your decramastic roof contains asbestos, follow these steps to ensure safe removal and disposal.

Step 1: Avoid DIY Removal—Only Licensed Professionals Should Handle Asbestos

Why You Shouldn’t Attempt DIY Asbestos Removal Removing asbestos roofing yourself is illegal for friable and most non-friable asbestos in New Zealand due to the significant health risks. Only licensed asbestos removalists have the necessary training, protective gear, and equipment to manage asbestos safely.

What DIY Removal Risks Involve:

  • Improper handling can release asbestos fibers into the air.
  • Exposure to airborne fibers can lead to long-term health conditions.
  • Non-compliant removal may incur fines under WorkSafe NZ regulations.

Step 2: Arrange for a Professional Asbestos Survey

Confirm the Presence of Asbestos Before planning removal, hire a licensed asbestos surveyor to inspect your roof and confirm whether it contains asbestos. This survey is crucial for determining the type and condition of asbestos, which impacts the removal process.

Cost of Asbestos Survey in NZ: In New Zealand, a professional asbestos survey generally costs between $400 and $800, depending on the property size and complexity of the job.

Finding a Qualified Surveyor: Use WorkSafe NZ’s directory or seek recommendations to find reputable, licensed surveyors with experience in residential roofing.

Step 3: Obtain Quotes and Hire Licensed Asbestos Removalists

Choosing the Right Asbestos Removal Company Once asbestos has been confirmed, get multiple quotes from licensed asbestos removalists who specialize in roofing. Be sure to select a company that follows WorkSafe NZ guidelines for safe asbestos handling and disposal.

Cost of Asbestos Roof Removal: Expect to pay between $2,000 and $10,000 for professional asbestos decramastic roof removal, depending on the size, condition, and access to the roof.

What to Look for in a Removalist:

  • Verify their license and insurance for asbestos work.
  • Ask for references or reviews to ensure quality and compliance.
  • Confirm they will handle waste disposal according to local laws.

Step 4: Understand the Safe Removal Process

How Professionals Remove Asbestos Decramastic Roofs Licensed removalists follow a strict process to ensure asbestos is contained and removed without contaminating the surrounding area. Here’s what typically happens:

  1. Containment Setup: The area around the roof is secured, and protective barriers are set up to prevent fiber escape.
  2. Wet Removal Technique: To reduce dust, the roof is wetted before removal. Wetting the roof keeps fibers from becoming airborne.
  3. Careful Dismantling of Roof Panels: Each roof panel is carefully removed to avoid breaking, which could release asbestos fibers.
  4. Double-Bagging and Labeling: Asbestos waste is securely double-bagged in heavy-duty plastic, sealed, and labeled as hazardous material.
  5. Transportation to a Licensed Disposal Site: The bagged asbestos is transported to a certified landfill that accepts asbestos, where it’s disposed of according to environmental regulations.

This step-by-step approach minimizes risks and ensures the asbestos roof is handled with the utmost care.

Step 5: Conduct a Final Inspection and Air Quality Test

Why a Clearance Inspection Matters After removal, a licensed assessor should conduct a clearance inspection to verify that the site is free of residual asbestos fibers. This may include air quality testing to ensure no fibers remain in the air.

Cost of Clearance Inspection: In New Zealand, a clearance inspection typically costs between $200 and $500, depending on the extent of the testing required.

Final Documentation: Once the site passes inspection, the removalist will provide you with a certificate of clearance, confirming that your home is now asbestos-free. Keep this documentation for future reference, especially if you plan to sell the property.

Why Proper Asbestos Roof Removal Is Worth the Investment

Attempting to cut costs with DIY asbestos removal or unlicensed contractors may seem tempting, but the risks far outweigh the savings. Non-compliant removal can lead to serious health risks, legal consequences, and financial penalties. Professional asbestos removal not only ensures compliance with WorkSafe NZ and Health and Safety at Work (Asbestos) Regulations 2016 but also protects the health and safety of your family and community.

Conclusion

If your home has an asbestos decramastic roof, the only safe way to handle removal is through licensed professionals. By following these steps—arranging for an asbestos survey, hiring experienced removalists, and conducting a final clearance inspection—you’ll ensure that your home is protected from asbestos hazards. Safe asbestos removal protects your health, meets legal obligations, and preserves the long-term value of your property.
