One of the ancient types of roofs is consideredgreen Previously, the buildings were covered with a floor of hewn semi-logs or poles, the top was covered with bark in several layers, and the turf was placed on it. In order to prevent it from sliding down, a log or a board was installed on the ramp. From above laid out turf with moss or grass.
Today, the green roof regains its popularity.It has an attractive appearance and keeps the heat inside the building, preventing it from overheating in the summer. Soil balances temperature fluctuations and protects materials from the effects of negative factors, increasing their useful life. If you install such a roof, then you can get rid of external noise. Modern technologies allow to equip such a system independently, increasing the area of the site and successfully fitting this exterior element into any landscape.
Why choose green roofing
The green roof has many advantages over the traditional one:
- durable;
- retains rain drains;
- has the qualities of thermal insulation;
- improves the environment.
Vegetable roof will last much longercommon as plants and soil protect materials from the weather. If you properly care for such a system, the life of the roof can exceed 20 years. If your house is built in a region whose climate is characterized by frequent and heavy rainfall, then a green roof can be an excellent solution, as it can cope with large amounts of water.

Main roof layers
Before starting work on landscapingroofing, it is worth considering what siding to fit the green roof. It may be worth choosing vinyl, the appearance of which can imitate natural wood. A green roof has many advantages, but for an incompetent user it can be a real problem. Therefore, before starting the arrangement of such a system, it is necessary to become more closely acquainted with the main layers. The topmost ones are ornamental plants, under which there will be a substrate, then comes the filtering and drainage layers, followed by a protective layer and waterproofing. The roof should be composed of traditional materials such as vapor barrier and base, these layers will be the lowest.
Features of arrangement of the green roof
If you will realize a green roof, thenInitially, a foundation should be created which consists of supporting structures. If we are talking about a flat roof, then concrete slabs will become the base, whereas for the pitched roof the main element will be a continuous crate. If the arrangement of the green roof is on the old surface, for example, on the tile, then it must be removed. Flat roofs should be given a small slope, which should be directed towards the drain. The optimal slope setting is the limit from 1.5 to 5 °. To create a slope it is best to use a cement-sand mortar.
Waterproofing
A house with a green roof must havewaterproofing layer. This is due to the fact that the plants will be watered, and water at the same time can leak to materials that do not like moisture. To do this, you can apply a polyethylene film or polymer membrane. To do this, quite often used and liquid rubber. Waterproofing is located on the roofing.
Фасад дома с зеленой крышей тоже должен to conform to the plan, that is why it is better to use natural materials for cladding the walls of such a house. Creating a layer of waterproofing, you can use a coating of marine plywood. When using boards it is necessary to exclude gaps and cracks between them. To increase the effectiveness of waterproofing it is best to lay the polymer membrane in two layers. The bottom layer should be fixed mechanically, and the top should be melted. The resulting seams are soldered together.
Warming
Green roof, a photo of which you can considerin the article, must necessarily be insulated. Insulating layer is most often created from cork slabs; polyurethane is also successfully used, which is applied in foam form. You can also apply extruded polystyrene foam. Plates should be laid as closely as possible to each other, if the top layer creates a slight pressure, then you should use special glue. Some experts do not strengthen the slabs to the base, as the pitched roof does not require additional thermal insulation, because this layer is already in the attic space between the rafters. But when green moss is used, it is not at all talking about weatherization, since this plant is used to insulate roofs of houses.
Creating a barrier for plants
Дом под зеленой крышей будет смотреться очень It is beautiful, but it is required to observe the technology of work on its arrangement. It is important to have a root-protective layer, which will exclude the germination of plants deep into the roof. The barrier is most often the polymer film or ordinary foil. An excellent solution would be a film with a metal coating, which is placed on a waterproofing layer.
Drainage layer
Drainage material will delay certainthe volume of fluid that is necessary for normal plant life. And the water should move along the roof towards the drain. If your house has a flat roof, then you must create conditions that will prevent water stagnation. For the lower drainage should be laid expanded clay, which has a medium or coarse fraction. Excellent results can be achieved using chipped pumice, polyamide, perlite coconut. Special artificial mats, which have the appearance of nets and are very flexible, are being implemented today. If you do not have these materials, you can use loosened clay or gravel. In order to ensure effective water flow, it is possible to install additional perforated tubes.
Filtering layer
Green color of the roof can be created not only withusing plants, but also modern covering materials such as metal tiles. As practice shows, this option is less time consuming, because after laying the roof will not have to take care. Among other things, the green roof has many layers, among which should be highlighted filtration. It is necessary for the retention of unnecessary precipitation. An excellent filter is geotextile, which has a high density. With this cloth, it is possible to eliminate the mixing of drainage with the soil, which can occur over time. Geotextiles are overlapped.
Lathing when planting a sloping roof
Необходимо применить георешетку, так как при the sloping slope of the slopes of the soil can simply slide down. The geogrid is lightweight and has the appearance of plastic cells. If there is a green roof with a small slope, it will be enough to prepare wooden partitions that will serve as a batten. Wooden slats must be laid in such a way as to create an interesting geometric pattern. Along the perimeter for fixation should be installed bumpers.
Fertile layer
If you decide to green the roof, then asFinishing material for walls can be used siding. Green roof on your house may not be in this case, because such decoration for walls can be used in tandem with Ondulin. After laying all the layers you need to create a fertile soil, the thickness of which can be equal to 10 cm. The soil should be stable and compacted, but the usual mixture for the garden is not suitable.
Conclusion
After laying the ground you can do landingplants. It is important to take into account that the conditions above will be close to the desert. If you want to give preference to trees, then you should choose dwarf species that have a small root system.
