Starting at the base of the roofline, position the tile trim against the battens, secure it and place the internal rubber joiner on the upper end of the trim.
 
Please note the tile trim should overhang by a minimum of 50mm, to allow for proper fitting of the end cap.

Allowing a 5mm gap for expansion, position the second length of the tile trim into the rubber joiner, and join both lengths using the external joiner piece.
 
it is recommended that the upper end of the tile trim at the roof apex is cut to the required length and angle before nailing to battens.

Finally the top ridge unit is fitted at the apex and secured using the innovative butterfly fixing mechanism (see image above).
 
Neutral curing silicone is recommended to seal all joints.
