How Long do Asbestos Roofs Last?
Asbestos roofs’ lifespan depends on the thickness of the material. If you opt for a thin sheet, you can expect the roof to last for around 30 years. The lifespan can go over 50 years more with a thicker sheet. However, concerns over its impact on human health have led to many countries banning it from being used in buildings and other structures.
What is an Asbestos Roof?
An asbestos roof is made up of sheets of asbestos that are bonded together and then covered by tar paper or felt. It was used extensively in construction as one of the most popular roofing materials until it was banned in the UK in the 1980s. In most cases, people who work on these roofs will be wearing protective clothing such as gloves and boots. However, if they are not, there is still a risk of developing mesothelioma and other types of cancer.
Types of Asbestos
There are two main types of asbestos: chrysotile and amphibole. They both have different properties. Chrysotile is considered to be less harmful than amphibole. Both types of asbestos were commonly used in building materials before their use was restricted. Other types include blue asbestos and brown asbestos and white asbestos.
The Use of Asbestos in Construction
Before the 1980s, asbestos was widely used in construction. Its popularity grew because it provided insulation that could withstand extreme temperatures. It also helped keep water out of the structure of the building. However, after studies showed that it caused cancer, it became illegal to use in the United Kingdom. This has since been adopted across Europe and North America.
How Safe is Asbestos Roofing?
The main problem with this type of roof is that it contains asbestos that poses health risks. This means that it causes serious health hazards when exposed to the dust created during its installation and removal. Asbestos can also pose a threat when it gets into the air through cracks and holes in the roof. Therefore, it is important to check your roof regularly to ensure that it is safe. You should also make sure that any workers working on your roof wear protective clothing and use masks while doing so.
When are Householders Likely to be Exposed to Asbestos?
You are likely to come across asbestos-containing materials at home. These include floor tiles, insulation, ceiling tiles, pipes, water tanks, fireplaces, wall panels, window frames, doors and siding. There are many ways that you could be exposed to asbestos dust. For example, if you live near a building site where asbestos products were being installed, you might breathe in the dust. Alternatively, if you have ever worked in a factory that produced asbestos products, you could inhale the dust or asbestos fibers from their production process.
Precautions to Take with Asbestos Roofing
If you suspect that your house has asbestos roofing, you need to contact a specialist company that deals with hazardous waste. They will be able to advise you on what to do next. One option would be to remove the roof completely and dispose of it safely. Another option would be to seal off the area where the roof is located. This way, it won’t create a hazard for anyone living nearby. Factory workers should use sufficient protective equipment to reduce their risk of exposure to asbestos fibres.
Can I Sell My Home With An Asbestos Roof?
If you want to sell your house, you need to know whether it has an asbestos roof. If it does, you will need to remove it before putting it on the market. Otherwise, you could face legal action if someone later develops an illness due to exposure to asbestos.
What is the life expectancy of asbestos shingles?
Asbestos shingles typically last between 30 and 50 years.
Can an asbestos roof be repaired?
Yes, but only if you hire a licensed professional contractor to carry out the job. The best way to deal with asbestos roofing is to get rid of it entirely.
Can I remove asbestos roofing myself?
No, as it is illegal for you to do so without the correct safety equipment and training. It’s also dangerous because there is a chance that you could become seriously ill.
Do I need to hire a professional roofing contractor?
It depends on how much work needs to be done. If you’re going to replace just one section of the roof, then it may not be necessary to call a professional.
