Asbestos was a popular construction material in the eighties due to its fire proof and insulation properties. It is also a durable material that was used in roofing products because of its resistance to weathering and its ability to handle very high temperatures. However, when it was discovered that asbestos can cause respiratory diseases, it was no longer used for construction.
The problem is that structures that were built before the nineties are likely to have asbestos. It is therefore important to get a professional to carry out the removal of an asbestos roof in order to ensure that you are living in a healthy environment.
Dangers Of Asbestos Roofing
A roof that contains asbestos products can become a health hazard to the occupants of the building and the people who live in the vicinity. Asbestos that is in good condition does not pose a health risk but once it gets damaged, it releases fibers which can be inhaled.
These fibers, when inhaled, remain in the lungs for a long time before they begin to scar the lung tissues. Respiratory diseases can then develop including asbestosis, mesothelioma or even lung cancer which all cause difficulty in breathing. The symptoms of these diseases show up after very many years of exposure to asbestos fibers.
Importance Of Removing An Asbestos Roof
If you suspect that your roof contains asbestos, you can only know for sure by having the material tested. There are laboratories that can test materials to check for the presence of asbestos. If you do not want to go through the process of having the roof tested, then it is a good idea to assume that the roof contains asbestos if it was built in the eighties or before.
When the removal of the asbestos roof has been done, you will be sure that you are operating from a building that is healthy. In addition, when you have the asbestos roof removed, you will have the chance of increasing the value of your home. This is because you can use a new roof that is attractive and of good quality.
Safety During The Removal Process
When an asbestos removal contractor comes to your home to get rid of the asbestos roof, there are certain safety measures that will need to be taken. Before any work commences on the roof, it should be wetted so that the dust particles are contained. If wetting the roof will pose a risk to the workers, then the roof can be sprayed with a polyvinyl acetate (PVA) glue to contain the dust particles.
As the roofing sheets are removed, they should be lowered to the ground and should not be thrown down since this can cause the asbestos fibers to become airborne. The roofing sheets should then be immediately placed in plastic sheets, sealed and placed in a covered truck to be transported to the site of disposal. The roof and ceiling should then be vacuumed to remove any remains of dust. The yard should also be vacuumed to get rid of all dust particles.
An air monitoring exercise has to be done in the area where asbestos removal of the roof has taken place. The concentration of asbestos fibers in the air is measured to ensure that the air is safe for breathing.
