Important Install Notes

  • Do not turn up the sheets. For roofs with a pitch of under 5 degrees, please contact the manufacturer for specific installation instructions.
  • When laying the roof sheets, please ensure the sheets are laid straight, with no staggered sheeting.
    When installing the louvres, always remember to embed the foam into the roof sheet at least 3mm to create a watertight seal.
  • Silicone all joins, in particular ensuring that there is no gap between the foam.
  • Always follow the manufacturer screw pattern guidelines. These vary between normal areas and cyclonic regions.
  • The throat gap between the Vent-A-Roof louvres is recommended to be 50mm-75mm at a minimum.
  • For retro-fit installations, previous screw holes are to be sealed for waterproofing.
