Asbestos Garage Roof Removal: Why You Shouldn’t Attempt It Yourself

Asbestos Garage Roof Removal

Asbestos has long been recognised as a hazardous material, especially in construction. Many older buildings, including garages, have roofs containing asbestos. If you own a property with an asbestos garage roof, you might be tempted to tackle the removal job yourself. However, asbestos garage roof removal is a task that should never be taken lightly. This article delves into the dangers of DIY asbestos garage roof removal and underscores the importance of hiring professionals for this critical job.

Understanding Asbestos

What is Asbestos?

Asbestos is a group of naturally occurring minerals known for their fibrous composition and resistance to heat, fire, and chemicals. These properties made asbestos a popular material in construction, especially for insulation and roofing, throughout the 20th century.

Types of Asbestos

There are six types of asbestos minerals, categorized into two groups:

  • Serpentine: Includes chrysotile, the most commonly used form.
  • Amphibole: Includes amosite, crocidolite, tremolite, anthophyllite, and actinolite.

Each type varies in its physical properties and potential health risks, but all are hazardous when fibers become airborne.

History of Asbestos Use

Asbestos use peaked between the 1950s and 1980s. It was widely used in various building materials, including garage roofs, due to its durability and fire-resistant properties. However, as the health risks became more apparent, its use declined, and many countries implemented strict regulations or outright bans on its use.

Dangers of Asbestos

Health Risks

Exposure to asbestos fibers can lead to severe health issues. When disturbed, asbestos releases tiny fibers into the air, which can be inhaled or ingested. These fibers can cause inflammation and scarring in the lungs, leading to serious diseases.

Asbestos-Related Diseases

Long-term exposure to asbestos can result in various illnesses, including:

  • Asbestosis: A chronic lung disease causing scarring of lung tissue.
  • Mesothelioma: A rare cancer affecting the lining of the lungs, chest cavity, or abdomen.
  • Lung Cancer: Increased risk for those exposed to asbestos, especially smokers.

Identifying Asbestos in Your Garage

Signs of Asbestos

Identifying asbestos in your garage roof isn’t always straightforward. Some indicators include:

  • Age of the roof: Buildings constructed before the 1980s are more likely to contain asbestos.
  • Material type: Corrugated cement sheeting, often used in garage roofs, is a common asbestos-containing material.

Professional Inspection

To accurately identify asbestos, a professional inspection is necessary. Certified inspectors can safely take samples and test them in a lab to confirm the presence of asbestos.

Why DIY Asbestos Removal is Dangerous

Risk of Exposure

DIY asbestos removal exposes you to harmful fibers. Without proper training and equipment, you can easily release asbestos into the air, increasing the risk of inhalation and contamination.

Lack of Proper Equipment

Professional asbestos removers use specialized equipment, including protective suits, respirators, and HEPA-filtered vacuums. Without these, DIY removal can be hazardous and ineffective.

Legal Implications

Many regions have strict regulations regarding asbestos removal. DIY removal may not only pose health risks but also legal consequences, including fines for non-compliance with safety standards.

Professional Asbestos Removal

Certification and Training

Certified asbestos removal professionals undergo extensive training to handle asbestos safely. They are knowledgeable about proper procedures and legal requirements.

Safety Protocols

Professionals follow stringent safety protocols to minimize exposure risk. This includes sealing off the area, using wet methods to reduce dust, and proper ventilation.

Equipment Used

The right tools are essential for safe asbestos removal. Professionals use:

  • Protective gear: Suits, gloves, and masks.
  • Containment materials: Plastic sheeting and duct tape.
  • Specialized vacuums: HEPA-filtered systems to capture airborne fibers.

Cost of Asbestos Removal

Factors Affecting Cost

The cost of asbestos removal can vary based on several factors, including:

  • Size of the roof: Larger areas require more time and resources.
  • Condition of the material: Damaged asbestos may require more careful handling.
  • Accessibility: Hard-to-reach areas can increase labor costs.

Cost vs. Safety

While professional removal can be costly, the investment in safety and peace of mind is invaluable. Cutting corners with DIY removal can lead to severe health risks and higher long-term costs.

Legal Requirements

Regulations on Asbestos Removal

Most countries have strict regulations governing asbestos removal. These laws ensure that the process is handled safely to protect both the workers and the public.

Permits and Documentation

Professional asbestos removal companies are well-versed in obtaining the necessary permits and maintaining documentation required by law. This compliance is crucial for legal and safety reasons.

Steps in Professional Asbestos Removal

Initial Assessment

A thorough assessment is the first step. Professionals inspect the site, take samples, and develop a detailed plan for safe removal.

Containment Procedures

The work area is sealed off to prevent fibers from spreading. Negative air pressure units and other containment measures are used to keep the site secure.

Safe Disposal

After removal, asbestos materials are carefully sealed and transported to licensed disposal facilities, ensuring they do not pose a risk to the environment or public health.

Choosing the Right Asbestos Removal Company

Checking Credentials

Ensure the company you choose is certified and licensed for asbestos removal. Verify their credentials and check for any history of violations or complaints.

Reading Reviews

Customer reviews and testimonials can provide insights into the company’s reliability and quality of service. Look for consistent positive feedback and any red flags mentioned by previous clients.

Post-Removal Procedures

Air Quality Testing

After removal, air quality testing ensures that the area is free of asbestos fibers. This step is critical for confirming the safety of your garage.

Future Precautions

To prevent future asbestos exposure, consider replacing your old roof with modern, asbestos-free materials. Regular inspections can also help detect any issues early.


Removing an asbestos garage roof is a task that demands professional expertise. The health risks and legal implications make DIY removal a dangerous option. Hiring certified professionals ensures that the job is done safely, protecting you, your family, and the environment. Always prioritize safety over cost when dealing with asbestos, and take the necessary steps to maintain a healthy, asbestos-free home.
