Installation is done on full wooden decking only (thickness >24 mm).
For pitches < 35% is recommended to install a previous protection layer.
Prepare base course cutting lengthways tile tabs. The eaves course is then bonded to the adhesive tabs of the base course.
Use five 20 mm large headed 3 galvanised nails per shingle. Nail through strip centre band and into the top edge of the lower course.
If needed shorten the first left (or right) strip by half a tab. On completion check the tile bonding, use adhesive to reinforce laps as required.
