Set out the first second and all the rest of slates on a pitched roof.
Setting out slate roof battens.
Setting out up the roof gauge set the first batten at eaves to allow the tails of the eaves course tiles to overhang the fascia by 40 to 45mm ie.
It also allows you to determine the holing gauge distance from hole to tail of slate and the number of linear metres of batten per m 2 of roof.
Holing gauge mm battening gauge mm m batten per m2.
The slate or tile manufacturer or supplier will specify the spacing of the battens up the roof for the particular type of covering this spacing is referred to as the gauge the gauge may depend upon the pitch of the roof and the amount of.
Spacing the battens.
Set the last batten at the ridge so that the ridge tiles will overlap the top course of tiles by at least 75mm.
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.
Holing gauge mm battening gauge mm m batten per m2.
The next thing to do is to work out the spacing for the battens up the roof.
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.
Lay the roof slates.
This table allows you to confirm the correct batten gauge distance between battens for your chosen slate length and lap.
Roofing battens are nailed into the rafters or roof joists or trusses and provide support for the roof tiles or slates.
Battens also play a part in ensuring the rigidity durability and weather tightness of the finished roof.
Slate length mm battening gauge mm m batten per m2.
Roof battens and gauge the gauge is the space between the roof battens this will set the overlap of your chosen slate in most cases.
Set out the first second and all the rest of slates on a pitched roof.
The batten gauge can also be calculated using the formula.
Now the roof has been set out correctly with the battens at the right distance apart its time to lay the slates.
