Battening and Holing Gauges for Slate Roofing
The table below gives a range of sizes for 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 m2 of roof.
For headlaps not shown please see our Roofing brochure for a more comprehensive list or contact us.
