Yes, you can and should replace an asbestos garage roof with a non-asbestos material. Replacing an asbestos-containing roof with a safer alternative is a responsible decision for both health and safety reasons. Asbestos was widely used in garage roofs due to its durability and resistance to heat, fire, and chemicals, but it poses significant health risks when its fibres become airborne and are inhaled. By replacing the roof with a non-asbestos material, you eliminate these risks and improve the safety of your property.
Why Replace an Asbestos Garage Roof?
There are several compelling reasons to replace an asbestos garage roof:
- Health Risks: Asbestos fibres, when disturbed, can become airborne and pose serious health risks if inhaled. These fibres can cause lung cancer, mesothelioma, and asbestosis. Replacing the roof removes the source of potential exposure.
- Deterioration Over Time: Asbestos cement roofing sheets can deteriorate over time due to weather exposure, physical damage, or age. This increases the risk of asbestos fibre release, especially if the material becomes cracked, broken, or friable (easily crumbled).
- Regulatory Compliance: Current regulations require that asbestos materials be managed safely and, when necessary, removed by licensed professionals. Replacing the asbestos roof with a non-asbestos material ensures compliance with safety standards and regulations.
- Property Value: Removing asbestos materials from your property can enhance its value and appeal. Many buyers are cautious about properties with asbestos, so replacing the roof can make your property more attractive on the market.
The Replacement Process
Replacing an asbestos garage roof with a non-asbestos material involves several key steps:
1. Asbestos Survey and Risk Assessment: Before any work begins, a professional asbestos survey is conducted to identify and assess the condition of asbestos-containing materials (ACMs) in the roof. This helps determine the safest method for removal.
2. Safe Removal of Asbestos Roof: The asbestos-containing roof must be removed by a licensed asbestos removal contractor. The removal process includes establishing a controlled area, using wet removal methods to minimize fibre release, and safely disposing of asbestos waste at a licensed facility.
3. Selecting a Non-Asbestos Roofing Material: After the asbestos roof is safely removed, you can choose a suitable non-asbestos roofing material. Common options include:
Metal Roofing: Durable and long-lasting, metal roofs are resistant to weather, fire, and pests.
Polycarbonate or Fiberglass Panels: These materials are lightweight, durable, and resistant to corrosion and UV damage.
Bitumen Roofing Sheets: Flexible and durable, bitumen sheets are easy to install and provide good weather resistance.
Corrugated Roofing Sheets: Made from materials such as steel or plastic, corrugated sheets offer strength, durability, and a modern aesthetic.
4. Professional Installation of New Roof: A qualified roofing contractor should install the new roof to ensure it is properly fitted and sealed, providing long-term protection for your garage and property.
Benefits of Replacing with Non-Asbestos Material
Replacing your asbestos garage roof with a non-asbestos material provides numerous benefits:
- Improved Safety: Eliminates the health risks associated with asbestos exposure, ensuring a safer environment for you and your family.
- Enhanced Durability and Aesthetics: Modern roofing materials often offer greater durability, improved energy efficiency, and a more aesthetically pleasing appearance compared to older asbestos cement sheets.
- Increased Property Value: Removing asbestos materials and replacing them with safer alternatives can enhance the value and appeal of your property.
- Peace of Mind: Knowing that your garage roof is free from asbestos provides peace of mind and reduces the worry of potential health risks and legal liabilities.
Costs and Considerations
When planning to replace your asbestos garage roof, consider the following:
- Cost of Removal: The cost of asbestos removal can vary based on factors such as the size of the roof, its condition, and the complexity of the removal. It’s important to get quotes from licensed asbestos removal contractors.
- Cost of New Roofing Material and Installation: The cost of the new roofing material and installation will depend on the type of material chosen and the size of the garage. Some materials, like metal or polycarbonate, may have higher upfront costs but offer greater longevity and lower maintenance.
- Professional Contractors: Always hire licensed professionals for asbestos removal and experienced roofing contractors for the installation of the new roof. This ensures compliance with safety regulations and quality workmanship.
Conclusion
Replacing an asbestos garage roof with a non-asbestos material is a wise decision that improves safety, enhances property value, and provides peace of mind.
