Wind classification Tile installation Ancillary installation
Edge of roof Field of roof Ridge, hip and barge tiles
less than N2 Mechanically fasten each full tile in second course and then every second tile in every course, or every tile in each alternative course. Mechanically fasten each tile
N2—N3 Mechanically fasten each full tile in second course Mechanically fasten each second full tile in every course

Notes:

  1. Mechanical fastening can be achieved with either nails, screws, clips or flexible pointing materials complying with AS 2050.
  2. For the purposes of this Figure, "edge of roof" is a 1.2 m wide band bounded by the eaves, ridge, hips and barge measured towards the "field of roof".
