Installation Guidance - Decra Oberon

Ridge/Barge Cap with Decra Universal Ridge/Hip Vent

  1. Cut the roofing felt back to allow a 5mm continuous air gap on either side of the hip tree.
  2. Nail 50 x 25mm batten to the tiling battens on each side of the hip using galvanised nails.
  3. Cut tiles to raking angle to suit. Turn edge of tiles up to form a 25mm upstand against the batten.
  4. Position Ridge/Barge Cap over the top batten and upstand edge of tile.
  5. Pulling the bottom edge of Ridge/Barge Cap away from the upstand edge of the tiles, slip Universal Vent strips into position on each side of the Ridge/Barge Cap.
  6. Install Universal Vent strips continuously throughout the whole length of the hip on both sides. Ensure there are no gaps between each strip.
  7. Nail Ridge/Barge Cap and Universal Vents through the downturn of the cap into the tile upstand and face of the top batten. Use 1-no Decra Nail each side of the Ridge/Barge Cap near the end lap.

NOTE: The Ridge/Barge caps have a slight taper in their design. Place the wider end of the ridge over the narrower end of the ridge beneath (overlap areas shown shaded grey).
