  • Water Tanks and Different Roof Types
    • ]]>     Rainhaven-Water-Tank-sister_2Although no longer used in new houses, asbestos in a cement matrix may be present in some older type roofs (pre 1970s). Although asbestos fibers are dangerous to health when inhaled in sufficient quantities, it is not believed that asbestos in drinking water poses a risk.

    Asbestos fibres have been detected in drinking water throughout the world with no known health effects.

    Roofing material should be left undisturbed as far as practicable since asbestos fibres, while bound securely in fibro-cement sheeting, can be released into the air by actions such as cutting, grinding or drilling. High pressure roof cleaning methods should also be avoided.

    Where the roof catchment area has deteriorated badly it should be replaced with asbestos-free substitutes.
