There exist exceptions but climbing plants (climbers) aren't usually used on roof greenings. With a roof greening, however, garlands and other alternative plants are used for transparent "green roofs" and can be created! Of course this is a question of the sub-construction: individual, free tight cables are sufficient for garlands, many bars or cables and at best a stable clamping frame are best used for green roofs. From our examples, learn what is to be observed about 'green roofs' and also see which plants are suitable. You also might take a look at our pergola page.
Particularly grape vines are suitable for green garlands, roofings, pergolen, galleries etc., However, This type of roof greening should always remain airy (due to the risk of mildew). For thicker green roofs Dutchman's Pipe, Akebie and Wild vines are suitable. The greening of roofs takes years. Strong growing Annuals are suitable for green garland, because there are hardly any static problems due to the manageable foliage development and the annual death. With vigorously winding plants such as Wisteria, Bittersweet, Knotweed, and Kiwi it is essential to ensure that cables are not permanently entwined. Details for a parallel root / shoot training can be found on the 'Wisteria' page.
In Baroque garden art, the people had been experimenting with hanging vine garlands, or so-called 'festoons'. Later, after the electrification of rural electric lines across a courtyard, strong tension cables were often led and used at the same time as a tether for a Garland of vines. For such practical usage, farmers have always been enthusiastic! Whether cable and anchoring for such additional loads are suitable, this must be clarified in each individual case. Ropes were often also only tightened up for growing plants, however. FassadenGrün has derived the system 0040 from these arrangements. You can also find information about unusual static features etc., there. With multiple, parallel executed garlands of this cable system, small green roofs between two walls can be created. If necessary, wire rope can be combined with growth fields on a wall.
Green wire lines over and across roads are often found in the southern states of Germany, for example, Freiburg/Breisgau. Unlike a courtyard greening here permits may be necessary because road space is required and claimed. The liability for possible damage (for example: broken hanging tension cables) should be clarified with the authorities, then nothing stands in the way of a road greening. Naturally, the greenings will usually be limited to a narrow streets, alleys and pedestrian zones.
Fan-like and interlaced strands are particularly suitable for pulled up overhead cable modifications of system 7060 with crossing wire design. Green leaf covers should be as high up as possible and pulled and adjusted for that certain dip in the rope. Also leaves and shoots, which will hang downward, can unfold better and disturb less, because the sufficient passage height is secured. Points of distribution for the cables are often set in separate timber columns, as with wire frameworks are set to posts in the ground to be supportive in accordance with cable system 0050 as bracing. And if necessary can be anchored in a nearby wall with short tensioning wires or stainless steel threaded rods (see photo). An attachment within the upper range of the wall is permissible only if the upper stones are held by a peripheral tie beam or are resting upon a heavy concrete roof slab, otherwise one must be more deeply fastened. At property boundries if necessary a separate approval is to be obtained during excess of local fence heights. If many ropes of a point go off, rings with screw links are to be inserted. Then it should be used, in any case, only 3 mms of rope, so that the ropes remain the ' weakest limb ' in the system and load points do not affect the posts too strongly.
