Hi
One question I missed is on tiles like Ludlow Major interlocking or Redland 49's the soaker is laid on top of the tiles abutting a wall. Is there any reason why instead of forming the soaker from one long length of lead covering many tiles can it be done per tile ie to the tile length plus the top 'hook over' or using lead clips to secure and an over apron to cover upstands.?
many thanks greengrass (not again!!!!)
