The battens should be laid out over the setting out nails and cut to size. All joints should be square and cut to the centre of the rafter or truss. Joins should be staggered throughout the roof with no two joins occurring on the same rafter or truss in adjacent courses.
All tile battens should be nailed to each rafter or truss with at least one nail of sufficient length
to penetrate the rafter or truss by the thickness of the tile batten being used, eg 50 mm x 25 mm batten require 25 mm penetration.
If a cut course has occurred in the setting out, the tile batten should be angled to support the tile on the same plane as the rest of the roof.
