Tiles should be laid in accordance with AS 2050-1995. All courses of tiles should be aligned horizontally, vertically and diagonally in order to ensure that the roof presents a regular and even appearance. The tiles can be laid in either straight or broken bond. Where possible, the tiles should be fitted close together, (but not hard together) and should be parallel to one another. However, all tiles may be 'slack jointed' to compensate for the roof being out of square and to ensure gable ends finish with either full or cut half tiles.

The maximum slack joint gap should be 15 mm.

Tiles are always laid from right to left, commencing at the eaves course.

Setting-out

It is important to -

  1. Obtain straight lines at sidelaps
  2. Avoid narrow cut tiles at verges
  3. Ensure that tiles at verges are parallel to the verge

Mark ridge and eaves at equal intervals of three tiles plus where necessary an allowance for adjusting each tile joint to compensate for a difference between 'A' and 'B' and to finish with a half or full tile at each verge. Join marks with chalk line as shown.
