CAN A PREFA ROOF BE INSTALLED ON TOP OF CORRUGATED ROOF PANELS?
can a PREFA roof be installed on top of existing asbestos corrugated roof panels? This is technically possible, however, as a manufacturer of ecological aluminium roofs, we do not recommend it. As most corrugated roof panels contain asbestos fibres which are harmful to health, care should be taken to prevent these fibres from being released into the environment. These could happen by drilling or cutting, or by the continuing ageing of the material without further environmental influences. If the corrugated roof panel material is covered by an aluminium roof, the drying-out and ageing process would take its natural course. Therefore, from the point of view of health and ecology, we recommend avoiding such risks by removing any corrugated roof panels containing asbestos.
