Ridges Installation

Laying the top course of tiles when rafter lengths suits a full tile course. The back edge of the tile must be straightened out. This is usually done in the bender. Laying the top course of tiles when rafter length does not suit a full tile course.

Procedure

Measure the distance (A) from the last tile to the ridge board (Fig 12). Add 50mm to the measurement (turn up allowance) and mark the tile to be cut (Fig 13).

Bending and Cutting
Place the full-tile in the full-tile bending attachment which can be bolted to the bender. Line up the marks showing the bend line and bend the tile upwards (Fig. 7). Tiles can be bent in either the bender or, depending on the length, with the full-tile bending attachment. Finally cut along the marked cutting line using the guillotine or hand shears. It is essential to bend the tile before cutting to avoid tile distortion.

Installing the Top Course of Tiles
Install the top course of tiles to the ridge board by nailing each tile through the up stand to the ridge board in 4 places and nailing the bottom edge as previously described. Ensure that the top course of tiles follows the same pitch as the other courses (Fig. 14).
