How is it possible to replace individual interlocking tiles, without
stripping the whole roof?

In areas of moderate windspeed like round here (London) you often only
have to nail the tiles at the perimeter of the roof.

All concrete tiles should be nailed or cliped every other course and at
eaves two courses below ridge and two vertical rows at gables.
The reason for the double row fixing at ridge and gables is to stop the
vortex from sucking tiles off.
