ITALIAN SLATE
French covering
The
“French” covering is the cheapest one because it Is the lightest
but there is the disadvantage of a difficult intechangeability of
tiles.
It is different from the “French with hooks” for the fixing: the tiles are fixed by zinc-coated iron nails.
This roof covering, very used in France, is characterized by a vision of diagonal and parallel lines running from the ridge tiles to the eaves and crossing with each other.
