looking for some advice please. I recent bought a property which has a detached garage with a corrugated asbestos cement roof. It seems to be in reasonable condition but there appears to be a few small areas which are flaking. To what extent is this a risk/issue. I believe this type of roof is better left 'undisturbed' when in good condition, but the flaking issue concerns me a little. Is it likely to be a hazard or should I just leave it be?
