We are in the process of buying a late 1960's built house and the survey has found the hot water tank in the roof-space and the garage roof are constructed oif concrete-asbestos. Survery recommended replacing the water tank with a plastic one, but just leaving the old tank in the roof space as it would be too costly to remove.
Is there any risk of contamination in the rest of the house in having the old water tank sitting in the roof space?
