Roof Tile Batten Gauge

This gives 32 14cms which is the tile gauge you should use for the remaining battens to ensure correct spacing between them.

Roof tile batten gauge.

Batten gauge length of slate headlap 2. 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. So using the previous example divide your roof height of 450cms by the batten number of 14. The gauge is in fact the same as the margin which is the length of the tile exposed.

Battens should be fixed to rafters set at centres not more than 600 mm apart and should span at least 3 rafters. The result is the number of courses of tile on the roof rounded to a whole number. 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 batten gauge headlap 10mm.

Not more than one in four battens should be joined over one truss for gauges over 200mm. Recalculate your tile gauge based on the number of battens specified in step 7. The batten gauge can also be calculated using the formula. 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.

The holing gauge can be calculated as. Set the last batten at the ridge so that the ridge tiles will overlap the top course of tiles by at least 75mm.
