What size are slate battens?
For natural double lap slates (sized or random), the minimum width is 50mm and depth 25mm, for a span of up to 600mm. For natural double lap slates (fibre cement or concrete), the minimum width is 38mm and depth 25mm, for a span of up to 450mm; and 50mm width, 25mm depth for a span of up to 600mm.
How do you work out Batten gauge for slates?
Batten gauge = (length of slate-headlap)/2.
What is roof batten gauge?
Roofing Tool Supplies The Roof Batten Gauge is ideal for spacing and setting up roof battens, saving time, effort and money. Roof Batten Gauge. Used for spacing and setting up roof battens.
How do you gauge battens?
1 Measure distance between top of eaves batten and top of ridge batten. 2 Divide distance by maximum gauge of tile being used. 3 Round figure up to give number of courses up slope as a whole number. 4 Divide measured distance by number of courses to give batten gauge.
What size should battens be?
A true batten is 2-inches in width or smaller, but you can use larger widths by installing trim in place of a batten if you want a thicker appearance. They’re installed directly over the vertical panels to get the traditional look.
How thick is a tile batten?
And, as with all batten systems, you need to ensure you’re using the right fasteners for the job. Metal roof battens are usually 40mm high and made from 0.55mm gauge hi-tensile steel.
How far apart should battens be?
Typically, batten are spaced anywhere from 12” to 24” apart. I think it looks best to space them as close to 18” as possible, but that’s just a personal preference. Our wall is 164” wide, so we used 8 batten (for a total of 7 spaces) with a distance of 19.42 inches between each batten.
How much should slates overlap?
On a slate roof this is the critical overlap and is necessary to prevent water penetration and leakage. The roof pitch typically relates to the required head lap as follows: 20 degrees: 115 mm minimum head lap. 25 degrees: 85 mm.
What is the distance between roof battens?
Battens should be fixed to rafters set at centres not more than 600mm apart. They should span at least three rafters and be at least 1.2m long.

What is the standard batten gauge for 265x165mm plain tiles?
100mm
The number of roof tiles needed per square metre varies and can range from less than 10 to more than 60. Standard plain roof tiles typically measure 265x165mm. With a minimum headlap of 65mm and a maximum batten gauge of 100mm, these tiles will give a covering capacity of 60 tiles per metre squared.
What do you need to know about Batten gauge?
This table allows you to confirm the correct Batten Gauge (distance between battens) for your chosen slate length and lap. 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.
How to calculate Batten gauge for slate roof?
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. Batten gauge = (length of slate-headlap)/2. Holing gauge = batten gauge + headlap + 10mm.
