Decorative flashings

Where a top course tile is used the minimum coverage of the flashing is 100mm. If no top tile is used coverage should be extended to 150mm. The decorative section of flashing should be added onto the coverage such that it does not compromise the lap relative to the vertical joint and the nail holes.
