  • Long-term corrosion resistance
    The resistance of the used metals has been tested under conditions according to VDA 621 and ensures long-term ventilation function.
  • High ventilation cross-section
    The high ventilation cross-section of approx. 220cm²/m ensures the ventilation of the area below the roof covering in accordance with professional roofer rules.
  • Two colours, one role
    Coated on both sides in black and brown.


DELTA®-ALU ROLL can be easily aligned and attached thanks to the product name printed on it. It can be ideally adapted to the covering material thanks to the high material expansion in the edge strips.

The ridge and hip roll can be applied in just a few steps:

  • Selection of the roll width depending on the profile of the covering material.
  • The surface must be dry and dust-free. (For old roof tiles/concrete roof tiles, prime with DELTA®-HF PRIMER if necessary)
  • Roll out DELTA®-ALU ROLL and attach to the arris/ridge battens.
  • Peel off the separating strip and press the adhesive strip on.

Cover the arris/ridge tiles. Done!
