Corrugated roofing sheets were a popular roofing material in Hungary for many decades, particularly during the second half of the 20th century. Under the practices of the time, many corrugated sheets contained asbestos, which improved the material’s durability, fire resistance and strength. However, because of the health risks associated with asbestos, it is now prohibited in the construction industry.
Where can asbestos-containing corrugated roofing still be found in Hungary today?
Asbestos-containing corrugated sheets can still often be found on the roofs of homes, farm buildings, workshops, halls and warehouses built in Hungary before the 2000s. They are particularly common in rural areas, at agricultural co-operatives and on agricultural facilities. Asbestos-containing components may also be found in the roof structures of prefabricated apartment blocks.
Why is asbestos dangerous?
The danger of asbestos-containing corrugated sheets comes from the fact that microscopic asbestos fibres can become airborne and, when inhaled, lodge in the lungs. Over time, these fibres can cause serious respiratory diseases, including asbestosis (scarring of the lung tissue), lung cancer and mesothelioma, a rare but aggressive cancer of the pleura. The greatest risk is posed by damaged or ageing corrugated sheets, when the material’s structure has weakened and asbestos fibres can be released into the air. Asbestos-containing corrugated sheets are still present in many places in Hungary, and strict regulations govern the handling and removal of such materials because of the health risks. To reduce exposure, it is important for owners of affected buildings to understand the dangers of asbestos and, where necessary, contact specialists to ensure it is handled correctly.
How can you tell whether corrugated roofing contains asbestos?
A visual inspection does not provide a reliable answer. An expert examination is needed to determine this with certainty. Several companies in Hungary carry out asbestos testing: they take a sample of the corrugated sheet in question and have it analysed in a laboratory.
Asbestos may also be present in other building materials
It is important to know that asbestos may be present in other building materials besides corrugated sheets, including insulation materials, floor tiles and pipe insulation. These materials may still be present in older buildings in Hungary, so they require particular care during demolition or renovation. Testing building materials for asbestos is essential to comply with health and safety requirements and to ensure that asbestos removal is carried out professionally.
Demolition and transport of asbestos-containing corrugated sheets
Only a licensed, qualified company may remove asbestos-containing corrugated sheets. Strict safety requirements must be followed during removal to prevent asbestos fibres from becoming airborne. The specialists carrying out the work use protective clothing and specialist respirators. During removal, the corrugated sheets are wetted to minimise the release of dust and asbestos fibres. Transport is also subject to strict regulations: the sheets must be carried in sealed, labelled containers that prevent the hazardous material from escaping into the environment. In Hungary, only landfills with the necessary permits may accept asbestos-containing waste. It is therefore important to entrust this type of removal and transport work to a reliable, certified company.
Asbestos removal is not merely a legal requirement; it is also essential for protecting human health. Thorough inspection, professional removal and disposal in accordance with the regulations all help reduce the health risks caused by asbestos in Hungary in the future. If you suspect that corrugated sheets or other building materials contain asbestos, it is advisable to contact certified specialists who can offer the safest solution.
