    Ridge tile - mortar bed along full length each side?

    Marley modern conc. slates (large flat interlocking 420x290). Are the ridge tiles supposed to be bedded on mortar full length each side as well as ends? I had to take a load off to replace slates and they were bedded/pointed at the ends but apart from that no mortar along most of each side?
