Hi all

How is it possible to replace individual interlocking tiles, without
stripping the whole roof?
The tiles are cast (concrete derivative?) and have a single securing nail to
the top edge.
One side of the tile locks under and the other side locks over the adjacent
tiles.
I can't see how these can be removed individually, but equally, can't
believe that tiles are made such that you have to strip the entire roof to
replace one!

IME, they aren't nailed, except possibly the odd one at the edge.
You can normally slide the ones above and to the sides up, and
then manhandle a tile out. There may be some interlocking patterns
for which this isn't possible though.
