Battern Centres
RIDGE AND MONO RIDGE
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.
Steps for working out batten centres
When tiling a roof it is important to position the battens equidistantly from each other to prevent uneven courses. MONIER 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.
The four steps to working out batten centres are as follows:
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.
