What's under my roof?

[WabbitPoo]

In my loft on our 1950s build home in Wales, the slate roof has stuck to it paper bags of what looks like shredded paper or perhaps plastic. About half of these bags have fallen off the slates and lie where they fell in the other, more recent loft insulation up there.

Can you tell me what the intended purpose of these bags were? is it to help stop the wind whistling under the slates? Would it be worth the work to replace them all, or newer verions thereof?

They may be insulation bags, they seem to be used these days primarily with suspended ceilings, but I have seen them used to insulate a loft, usually with a mesh across the rafters to stop them falling down, but obviously not in your case. Maybe some previous occupants wanted to keep the loft warmer for some reason.
