  • Long term corrosion resistance
    The resistance of the metals used, tested under off-shore conditions according to VDA 621, ensures the long-term ventilation function.
  • High ventilation cross section
    The particularly high ventilation cross-section of approx. 650cm²/m ensures ventilation of the level below the roofing in accordance with the roofing rules.


DELTA®-VENT ROLL PRO can be easily aligned and fastened thanks to the printed DELTA on it. Due to the high material stretch in the edge strips, it can also be optimally adapted to the covering material.

The ridge and arris roll is laid in just a few steps:

  • Selection of the roll width depending on the profiling of the cover material.
  • The substrate must be dry and dust-free when laying. (In the case of old roof tiles / concrete roof tiles, prime with DELTA®-HF PRIMER if necessary)
  • Roll out the DELTA®-PRO ROLL and fasten it to the ridge/ridge batten.
  • Pull off the backing strip and press on the adhesive strip in the edge area.
  • Cover arris/ridge tiles. Ready!
