Asbestos roofing was once a popular choice for homes and commercial buildings in South Africa due to its affordability, durability, and fire resistance. However, as research revealed the severe health risks associated with asbestos, its use became heavily regulated. In this blog, we’ll explore what asbestos roofing is, why it’s dangerous, the regulations surrounding it in South Africa, and what you can do if your property has an asbestos roof.
What is Asbestos Roofing?
Asbestos is a naturally occurring mineral that was commonly used in construction materials, including roofing, due to its heat resistance, strength, and insulating properties. Asbestos roofing typically consists of cement sheets reinforced with asbestos fibers, making it durable and weather-resistant. However, the health risks associated with asbestos have led to its phased-out use worldwide.
Why is Asbestos Roofing Dangerous?
Asbestos fibers are hazardous when inhaled, as they can become lodged in the lungs, leading to serious diseases such as asbestosis, lung cancer, and mesothelioma. The danger arises when asbestos roofing deteriorates over time, releasing harmful fibers into the air. Disturbing asbestos during renovations, cleaning, or removal can also release these dangerous fibers.
Asbestos Roofing Regulations in South Africa
In South Africa, the use of asbestos was banned in 2008 under the Asbestos Regulations of the Occupational Health and Safety Act. This legislation prohibits the manufacture, import, sale, and use of asbestos products. Property owners with existing asbestos roofing are required to manage it safely, ensuring it does not deteriorate or pose a risk to occupants. If removal is necessary, it must be carried out by licensed asbestos removal specialists.
What to Do About Asbestos Roofing
If you have an asbestos roof, regular inspections are essential to monitor its condition. If the roof is in good condition, it may not pose an immediate risk, but any signs of damage or wear should be addressed promptly. Replacing an asbestos roof is highly recommended to eliminate the health risks. Kloof Roofing’s roof replacement services can help you safely upgrade your roof with modern, safe materials.
