Batten Centres

Ridge and Mono Ridge

The undertile membrane should overlap the apex of a roof by at least 150mm. The ridge battens can then be permanently fixed.

Verges

The battens should not be cut until the tile setting out procedure has been completed.
Sufficient undertile membrane must be provided for water-proofing the verge detail.

Abutments

Sufficient undertile membrane must be provided as detailed in standard flashing requirements.

Gutters

Gutters should be installed before tiling commences.

General

Before tiling work commences, fascia boards, beam filing, valley flashings, plastering and painting work, should be completed to avoid unnecessary traffic on the roof.

 

THE FOUR STEPS TO WORKING OUT BATTEN CENTRES ARE AS FOLLOWS:

When tiling a roof it is important to position the battens equidistantly from each other to prevent uneven courses. Coverland Roofing has produced a simple formula using the tables provided to assist you in this task.

Follow these four easy steps to locate the batten centres of rafters ranging from 1 metre to 9.35 metres.

  1. Measure the complete rafter length from the apex of the roof to the end of the eave.
  2. Position the first batten as per illustration.
  3. Proceed to batten at centres obtained from the tables for the applicable pitch.
  4. Always ensure that the top batten is 25mm from point of apex.
