Flashing used to be done with lead foil sealed/glued with pitch, now it
is done with adhesive metal [usually aluminium] tape, hence "flashing

I wonder on what sort of construction?

In the UK where buildings pretty well all have stone walls, the lead
flashing is bent into a 'chase' created in the masonry, usually the mortar
between coarses, secured with lead wedges and mortar applied afterwards to
seal. A lime based mortar is best to accommodate some movement. Down the
edge of a roof where it meets the brickwork it will be cut into a step
shape to follow the line of the horizontal bricks. And it's still very
much in use today - despite the cost.
