|Description:||In the past few years the use of asbestos was used in the building as a material to add more strength and durability to it. But with the passage of time the use of asbestos decreased. It is said that 75% houses in the UK are made with asbestos. The total lifespan of an asbestos roof is hardly 40-50 years, after that the need of changing the roof is necessary. The lifespan of asbestos roof depends on many factors, its geographical location, maintenance and many other things involved.
According to a survey buildings made in the 1930s has asbestos and are still in good condition as they were at the time of installation. As a matter of fact, in most of the industrial properties the maintenance of the roofs is neglected. Homeowners only give attention when a leakage appears; they cover it up temporary with patching. But for asbestos they need a permanent solution as it can be harmful and dangerous.
Health risk from asbestos:
There is a campaign running with the name of ‘Be aware asbestos’, which is to inform people about the life threatening risks of asbestos. Statistics show that around 5000 workers die each year because of it and 20 tradesmen die every week. These shocking figures show that asbestos is still injurious to health.
Amazing part is that not only these tradesmen are affected by it, but also the people living around that building. The risk occurs when the property is damaged or disturbed, the asbestos fiber loses. When we inhale these tiny fibers, it doesn’t decompose and it stays in the lungs, which will eventually cause fatal diseases. The body safeguards fail to fight against them ending up causing following diseases.
• Lung cancer
Asbestos is still used in some roofs today and it works fine in start. With time it starts aging and that is the time it needs attention. One solution is to remove asbestos cement sheets with non-notifiable work. That means it can be removed only under the supervision of local authorities. The reason is asbestos contains dangerous elements like chrysotile. When asbestos sheets are exposed to UV rays, rain, sunlight, it can cause a greater risk to human health.
It is important to get it the asbestos cement sheet or roof changed before it’s too late.
Asbestos repairing options:
A new roof is always costly. Asbestos roof if damaged have no shortcuts for repairs, the only thing possible is a complete roof change. Changing asbestos can be very expensive, especially when it double skinned. The more the quantity of exposed asbestos the more it will cost.
It’s better to get a new insulated roof that will compliment all the priorities.
Over-cladding means to add a metal skin to the existing roof. This way it won’t cost much and the age of the roof can be increased. Since metal has a weight, additional consultancy from the engineer will be needed as it will affect the complete structure of the building.
Usually, homeowners coat their asbestos roof with special paint to increase its life. Special paints are used to coat these roofs, because the normal paint may fail to protect the roof. Coating can be cost friendly and can be a temporary solution to protect the roof and will help it to age for 20 more years.
If some part of roof is damaged from specific part it can be patched with the help of fabric, paint, tapes. But this is only a quick fix, in the long term any kind of damage will need proper attention and solution.|
