Don’t worry. Asbestos cement is not really dangerous, as long as the concrete is intact and you don’t touch it, there’s nothing to be afraid of.
It’s when it crumbles or you work on it, that you have to take care. The problem is Asbestos dust entering your lungs, where it’s very carcinogenic.
But intact walls and roof are okay.
Well put. My answer would have just been, that it’s possible, but that it can be very, very expensive.
