The decking to this flat roof has completely deteriorated. Back in the 70s it was the custom to lay flat roofs on chipboard or straw board. As you can see in the video, when water gets through to the roof decking it is completely destroyed and cannot even support the weight of the roof laid upon it. The entire roof collapses and there is no alternative but to completely strip the roof back to the bare joists and start again.
