Abstract
A roof covering for greening an inclined roof comprises a water-impermeable roof skin, a holding structure placed loosely on the roof, holding projections distributed on said holding structure and engaging in a plant-carrying layer, a tension-resistant filter layer beneath the holding projections, and a drainage underneath said filter layer and having distributed spacers in contact with said filter layer.

Roof covering for greening an inclined cold or warm roof having a supporting construction resting on walls and a water-impermeable roof skin, said roof covering comprising:
- a plant carrying layer applied on top of the roof;
- a non-rotting holding structure which is independent of the subjacent roof structure and of the roof skin, said holding structure being placed on the inclined roof loosely and largely free of tension and friction of the roof and being secured only at a roof beam against sliding;
- holding projections distributed over an upper surface of said holding structure and frictionally and thrust-absorbingly engaging in the plant-carrying layer to be applied to the upper side;
- said holding structure conducting thrust and connecting said plant-carrying layer with the roof beam;
- a filter layer beneath said holding projections;
- a drainage underneath said filter layer;
- said drainage being part of said holding structure;
- said drainage having distributed spacers in contact with said filter layer.

- said holding structure conducting thrust and connecting said plant-carrying layer with the roof beam;
- said holding projections in their totality comprising a three-dimensional, structure of linked fibers with interspaces between them for accommodation of at least a lower region of the plant-carrying layer to be applied;
- a tension-resistant filter layer beneath said holding projections;
- a drainage underneath said filter layer;
- said drainage being part of said holding structure;
- said drainage having distributed spacers in contact with said filter layer.
