You just slide the tiles above up, put a new tile on and slide them down

There isn't normally any nails.

What roof have you got?

A standard tiled roof will always have nails, normally aluminium,
sometimes copper. Every few rows according to pitch.

People like you continually providing duff information give Usenet a bad
