Sequence of layers

  • Sub-layer: vapor-permeable foil up to behind the lead flashing connection.
  • Counter battens and tile battens reapplied right up to the dormer.
  • Lead flashing or comparable metal connection profile, extending sufficiently over the roof tiles.
  • Side cheek cladding connects watertight to the lead flashing.
