![]() If you know how to identify asbestos roof tiles and suspect you have cement asbestos shingles, it is advisable that you monitor your roof to check for its health. Having or buying a home with asbestos tiles does not mean you need to remove the tiles especially if they are still in good health. This is why knowing how to identify asbestos roof tiles and removing asbestos roof tiles is highly recommended if they're damaged or old. Similarly any operation that causes abrasion of the tiles is potentially hazardous for the same reason. However, roof tiles can potentially become dangerous when the tiles begin to deteriorate thereby exposing the asbestos fibres. The dangerous fibres of the substance are kept firmly in place by the cement. In most cases asbestos roof tiles pose no health hazard in and of themselves. The simple answer to this question is no. The least hazardous type, chrysolite was the most commonly used type of asbestos in the manufacture of cement asbestos tiles. Its use was stopped in the UK in the 1960’s and was commonly used in pipe insulation and pipe panels. Each of these pose different levels of danger with crocidolite deemed the most dangerous. In the UK three types of asbestos were used in the manufacture of roofing products, namely crocidolite (blue asbestos), amosite (brown asbestos) and chrysolite (white asbestos). Once inhaled, they can lodge in the outer tissue lining of the lungs and abdomen, which over time leads to inflammation, scarring and the eventual formation of fatal diseases such as lung cancer. When they are exposed they can become airborne and inhaled. The problem with asbestos arose out of the full-scale mining, extraction and use of the substance in industry and thus therefore the amount of asbestos in the air. In the environment it poses virtually no threat to humans. Asbestos and its hazardsĪsbestos is a naturally occurring substance. New homes built prior to 1970’s with asbestos roofs, were lauded for the longevity of their roof systems, as the roofs had a life expectancy of 30-50 years. In addition to its heat and fire resistant properties, asbestos has excellent strength and durability features. Depending on the manufacturer, the cement tiles comprised typically of between 10-15% asbestos. Asbestos roofing tiles are actually largely made from cement, with the now banned product added into the cement mixture. Due to its heat and fire resistant properties asbestos was added to many roofing products including roofing tiles.Īsbestos tiles did not comprise solely of asbestos. One of the widest uses of asbestos in the building industry was in roofing. From the 1970’s onward, its use in industry began to be restricted and over the ensuing decades, asbestos became a banned substance throughout the industrialised world. Workers who handled asbestos or who used materials made from the material presented with lung and pulmonary diseases some of which, such as lung cancer and mesothelioma, were fatal. In the early 20th century however, there was growing concern over its use as cases and research began to appear implicating it in the death of asbestos miners and of factory workers. Its use in the building industry spans back thousands of years but full-scale mining of the substance and its use in industry began in the 19th century. ![]() Historically asbestos has been widely used in an array of building applications. Asbestos is a naturally occurring substance with many desirable properties making it a cheap and versatile material for use in industry.
