What are suitable roofing materials for rainwater collection?
Some types of roofing materials or roof paints may contaminate the rainwater you are harvesting. The most suitable types of roofing materials are: • Colorbond steel • Zincalume steel • Glazed tiles (well fired) • Concrete tiles • Clay tiles • Fibro (treated, newer type) Urban Tanks will advise you if you have any other type of roofing material. Newly painted roofs must use a special paint suitable for the collection of rainwater. This paint does not contain anti-mould agents. Older paints may be acceptable, but if in doubt, please seek advice from Urban Tanks.
