I've just demolished a 1930s garage that had an asbestos cement sheet roof. I won't bore you with all the stupidity but you'd think I was trying to dispose of nuclear waste, the way the jobsworths at the tip reacted when they heard the A word. They aren't clever enough to be entrusted with judging between dangerous asbestos and asbestos that's almost completely encapsulated within a cement sheet so everything defaults to a major hazard. A nightmare, altogether.
