Roof is one of the areas where asbestos was utilised to the highest extent. Because it was fireproof and at the same time relatively inexpensive, its implementation was massive and worldwide. Despite the fact that it was banned around 1980s (however countries largely differ as for the time that ban was enacted), there are still hundreds of thousands of buildings which contain that material.
What is even more disturbing, roofs with asbestos can now become the biggest threat ever as the condition of the tiles and insulation may soon deteriorate to the extent that can actually pose a legitimate health risk. All that because of the fact that asbestos has a life expectancy of up to 50 years and that in itself should alarm millions of homeowners across the UK.
The history of asbestos implementation in the UK starts around 1920s. It was then when the first reports about this substance started to see the light of day – after that it was soon popularized as a practical way of cutting the construction bills. The material became a household name for its affordability, durability and the lack of heat transfer. Little, if anything, was then known about the toxicity of the fibres which are released into the air as the condition of the material worsens. Similarly, the lack of research into the potential consequences of asbestos exposure quickly made this material one of the most omnipresent ones in the world of construction.
These days, however, more and more dwellings erected decades ago are undergoing various renovations which often involve roof replacements. If that procedure is handled without proper care and necessary caution, asbestos can quickly disintegrate and become released into the air. That, in turn, is not only a problem for the contractor but also the immediate surroundings such as neighbours or members of the family.
This is why all major authorities such as Health and Safety executive advice to remove asbestos roof with the help of a trained and skilled professional. What needs to be stressed is the fact that only in such circumstances proper removal environment could be ensured. Though it is not advisable to raise the alarm, either, once you see something even remotely similar to what you might think is asbestos, you shall consult a licensed contractor to have your dwelling assessed in terms of need of asbestos removal. First of all, barring some obvious examples, this material can sometimes be really difficult to spot without significant expertise and, more often than not, conducting a thorough analysis.
