In-line Slate Ventilator

  • Ideal for roofs where the normal ventilation airpath is blocked by valleys, abutments, hips, dormer windows and firebreaks or party walls
  • Ideal for roofs where it is not possible to incorporate standard eaves or ridge ventilation


Marley in-line slate vents are designed to match the thin leading edge of slate profiles, providing completely unobtrusive, almost invisible roof slope ventilation. They are ideal for roof designs where the normal airpath may be blocked or where it is not possible to provide normal eaves or ridge ventilation.
