It sounds if I have the same asbestos roof as you. For future
reference how are planning on getting rid of it.

Get in touch with your local "Tidy Tip", or the council, or
use Google, and find out which tip accepts this stuff (they
will have an "enclosed" skip). Take the stuff there on a
trailer, and dump it. Call the tidy tip first to check
they've got room in the skip for it, it's normally emptied
once a week or so.

To get the sheets off, get some bolt cutters, and snip the
nuts in half, across the flats, so that they fall off the
bolts. 18" cutters are OK.
