Set the first batten at eaves so that the first course of tiles overhangs the gutter by 45 to 55mm or into the centre of the gutter whichever is the lesser distance.
Then determine the position of the highest batten at the top typically the top of the uppermost row of slates tiles.
Set the last batten at the ridge so that the ridge tiles will overlap the top course of tiles by at least 75mm.
Ensure that full support is provided to fix the ends of the battens at hips and valleys.
Check size and spacing of battens.
What roof pitch do i need for what slate size generally speaking 20 degrees is the lowest advisable pitch for a slate roof depending on the size of the slates and how much that the roof is exposed to.
