I note the health and safety photo on 9 May. I saw an exact repeat performance on a house in Yateley, North Hampshire two weeks ago.

A group of eight or nine were working off a ladder only. They stripped the roof, throwing the tiles into a heap on the drive, then re-tiled the roof completely. Duration: two days. Plant: one ladder. Safety equipment: nil. Job done. The latest in high-speed maintenance.
