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).
