Asbestos Shed: Everything You Need to Know
What is an Asbestos Shed?
An Asbestos shed refers to a structure—typically used for storage or utility purposes—built using materials that contain asbestos, a group of naturally occurring fibrous minerals. Asbestos was once hailed as a “miracle material” due to its durability, heat resistance, and insulating properties. During the mid-20th century, it became a popular component in the construction of garages, outbuildings, and garden sheds.
In these structures, asbestos cement sheets were commonly used for roofing and wall panels. These sheds were affordable, fire-resistant, and weatherproof, which made them a popular choice for homeowners and farmers alike.
Historical Use of Asbestos in Sheds
From the 1940s through the 1980s, asbestos was used globally in a wide range of building products. In countries like the UK, Australia, and the United States, prefabricated sheds made from asbestos cement were mass-produced. These sheds were often installed in both residential and industrial settings and were marketed as maintenance-free and long-lasting.
Unfortunately, at the time, the health dangers associated with asbestos exposure were not well understood or publicly acknowledged.
Health Risks of Asbestos Sheds
The primary concern with an asbestos shed is the potential release of asbestos fibers into the air. When asbestos-containing materials are intact and undisturbed, they typically do not pose a health risk. However, when these materials age, degrade, or are damaged (e.g., by drilling, sawing, or breaking), tiny asbestos fibers can become airborne.
Inhalation of these fibers can lead to serious and often fatal illnesses, including:
Asbestosis: A chronic lung disease that causes scarring of lung tissue.
Mesothelioma: A rare and aggressive cancer affecting the lining of the lungs or abdomen.
Lung Cancer: Increased risk in those exposed to asbestos, especially if combined with smoking.
Pleural Disorders: Such as pleural plaques, thickening, or effusion.
Due to these risks, many countries have banned or heavily regulated the use of asbestos in construction.
Identifying an Asbestos Shed
If your shed was built before the 1990s, there’s a chance it may contain asbestos, especially if it has gray, corrugated roofing or cement-like wall panels. Common signs include:
Brittle or chalky cement panels.
Corrugated roofing sheets with a fibrous texture.
Manufacturer markings that indicate asbestos content (in some cases).
Age and style consistent with mid-20th-century construction.
To be certain, it is always recommended to have materials tested by a licensed asbestos professional.
Can You Still Use an Asbestos Shed?
Technically, yes—but with caution. If the asbestos materials are in good condition, encapsulated, and not subject to regular disturbance, the risk is minimal. However, certain precautions should be taken:
Avoid drilling, cutting, or sanding asbestos panels.
Do not use high-pressure hoses to clean asbestos roofing.
Regularly inspect the shed for signs of wear, damage, or degradation.
Keep children and pets away from the structure.
Removing or Replacing an Asbestos Shed
Professional removal is strongly advised. In many jurisdictions, it is illegal for untrained individuals to remove asbestos materials. Licensed contractors follow strict protocols to safely dismantle, remove, and dispose of asbestos-containing components.
The process typically involves:
Sealing off the area.
Wearing personal protective equipment (PPE).
Wetting materials to prevent fiber release.
Careful removal and containment.
Transportation to approved hazardous waste facilities.
After removal, homeowners can replace the shed with modern materials like metal, PVC, or timber that are safe, durable, and environmentally friendly.
Costs Involved
The cost of removing an asbestos shed depends on:
Size of the shed.
Type and condition of asbestos material.
Local regulations and availability of removal contractors.
On average, professional asbestos shed removal might cost between $1,000 and $3,000, including disposal fees.
Legal and Environmental Considerations
Disposing of asbestos illegally or improperly can result in severe fines and poses serious environmental risks. Asbestos waste must be:
Sealed in leak-tight containers or double-bagged.
Clearly labeled.
Disposed of at a certified hazardous waste site.
Many countries have detailed regulations governing asbestos handling—consult your local health or environmental agency for guidance.
Modern Alternatives to Asbestos Sheds
Once removed, consider replacing your shed with safer and more modern materials:
Metal sheds: Strong, fireproof, and resistant to pests.
Plastic/PVC sheds: Lightweight, weather-resistant, and maintenance-free.
Wooden sheds: Aesthetic appeal and customizability (requires periodic maintenance).
Composite materials: Durable, environmentally friendly, and available in various styles.
Each of these options provides functionality without the health risks associated with asbestos.
Final Thoughts
While asbestos sheds were once a common sight due to their durability and cost-effectiveness, today they represent a potential health hazard. Understanding the risks, knowing how to identify asbestos-containing materials, and following safe removal practices are critical for protecting your health and complying with the law.
