Fixing roof tiles to battens.
Here s our quick four step process to help you get started.
Shingles and tiles are affixed using the battens as spacing.
Check size and spacing of battens.
Start by establishing the position for the lowest batten for the slates tiles on the roof allow for the overhang of.
The gauge is in fact the same as the margin which is the length of the tile exposed.
For example 25 x 50mm battens are required for single lap modern roof tiles laid on rafters with a 600mm span.
The updated bs 5334 code of practice for slating and tiling specifies a number of batten sizes based upon the span of the rafters and the product being used.

The spacing of the battens depend on the type of roofing material and are applied horizontally.
Just short of the centre of the gutter.
Ensure that full support is provided to fix the ends of the battens at hips and valleys.
The supplier of the tiles should recommend the spacing up the roof between the battens known as the gauge this usually varies according to the size of the tiles the pitch of the roof and the degree of exposure.
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.
Generally battens should be parallel to the eaves and ridge lines.
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.
