Shed Roof & Window (Carlisle CA1)

We have an old shed we are replacing.
The base / floor & bottom of walls are rotten but the roof & window are both OK. Roof was replaced a few ears ago & moss should brush off easily .
We are in Carlisle & not sure when we’ll be dismantling it yet. The new shed is due next week.

Any parts taken will need to be collected & is subject to us being able to dismantle without damaging
