Decra Oberon Unventilated Monopitch Ridges

Decra Oberon - Monopitch Ridge using Ridge/Barge Cap - Detail from drawing DPTE040


Installation Guidance -
1. Turn underlay 25-50mm up face of ridge/fascia.  

2. Create fixing position for Ridge/Barge Cap:

  • Fix batten to top of ridge fascia sized to span from back edge of fascia to top edge of top tiling batten.
  • Fix 50 x 25mm batten to back of batten above.
  • Fold Ridge/Barge Cap to form monopitch ridge profile capping.

3. 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).

Each Ridge/Barge cap should be secured with 2 nails on each side of the ridge cap through the pre-drilled holes. 

NOTE: Decra Oberon Ridge/Barge Caps are tapered to allow for laps.

NOTE: Where roof pitches exceed 35° it may be necessary to adjust the return angle of the downturned leg of the Ridge/Barge Cap and use an alternative size of ridge fixing batten.
