The legendary gardens of Semiramis on the roof of their own house is no longer a fantasy. Green roofing is a useful and aesthetic trend that has been liked in many countries. The article contains information on how and why roofs are being greened, presents the main types of high-rise gardening, and describes how to care for amazing oases.
The roof garden can be set up on both a small house in a private mansion and a small village. The fantasy of landscape designers has literally become cramped on the ground.
Benefits of the green roof:
The compositions delight the eye with juicy greens. Straight from the bedroom or living room you can get into a small cozy garden, sit in the gazebo, listen to the noise of the leaves and the murmur of a small waterfall.
This is especially true of stone houses with an asphalt yard. Herbal roofs compensate for the lack of greenery, not to mention the cleanliness of the air, which becomes much cleaner. If the house is located near the road, then the amount of dust and harmful impurities decreases.
The noise level decreases if the road passes near the house.
In the summer, you can enjoy the pleasant cool in the building, and more heat will linger here in the winter.
The roof on which the garden or lawn is located, will last longer, because it is protected from the aggressive influence of temperature drops, precipitation, wind.
A large recreational area appears.
Disadvantage near the house >, in fact, one, but it must be taken into account.
To enjoy the fresh breeze and the smell of flowers on the roof of a building, you need to be prepared for spending. To make high-quality waterproofing, you need a complex and rather expensive construction of the roof. But all owners of green roofs unequivocally argue that the cost of equipping such a roof is more than paying for the advantages it provides.
In order to stroll along the roof, admiring the green leaves, extensive and intensive gardens are divided.
The first ones are simple and universal. Suitable for any roof, including the pitched. Popular with owners of private houses, villas, garages. For them, you do not need to further strengthen the roof. The thickness of the soil does not exceed 15 cm. Often use rolled lawns. If the idea of a lawn seems boring, landscape designers are advised to plant drought-resistant perennials. Popular ascetic options: turf and moss.
On flat roofs you can create original compositions from plants in pots. For the winter, containers are brought into the room.
The advantages of landscaping roofs are obvious when a real garden is spread over your head, and when a modest roll lawn is located on the roof.
Not suitable for all buildings, as gardens create large load on the roof. They build gazebos, install benches, make pools, fountains, waterfalls. The thickness of the soil (over 1 m) allows you to plant and shrubs and trees.
Any green roofs look like layer cake.
The base is floor slabs , on which they create a slope. On pitched roofs make crate.
From the polymer membranes, liquid rubber or ordinary polyethylene form a waterproofing layer . It protects the roof from the water, which will water the plants.
Polyurethane foam, polystyrene foam, cork slabs are needed for heat insulation layer .
To avoid damage to the roof due to growing roots, a barrier is made. For him, suitable foil, polymer film or film with a metallic coating.
To trap the moisture needed for grass and trees, drainage is done.
The quality of rainwater and water for irrigation varies. To avoid unnecessary substances entering the multi-layer structure, a layer of geotextile is laid. Such a filter will prevent mixing of the fertile and drainage layers.
A light plastic geogrid is placed directly under the ground.
The final touch is fertile layer . From its quality will depend on the life of green space. We need special mixtures, light, porous, well absorbing moisture. Their components: peat, clay, perlite, expanded clay, slate, sand.
The structure of the “cake” and the material of the layers may differ.They are selected taking into account the particular building.
Ignorance of technology gives rise to various myths about herbal roofs. The most common ones are the following:
The design will certainly fail .
The construction must leak .
If you perform work without a project, payments, and by the forces of non-professionals hired “according to the announcement”, both of these things happen. Experts guarantee:
Do not fail. Before designing the structure, exactly estimate the load that the roof can carry.
Does not leak. Protects against leakage waterproofing and water drainage system.
Any roof can float away with flowers and greens. Only it will have to do in different ways.
Only an extensive version is suitable for pitched structures. Green lawn and low flowers will get acclimatized even at the height. Trees on such roofs, of course, do not grow.
are suitable for pitched structures. On flat structures, both extensive and intensive methods are applicable. The choice depends on the strength of the roof of taste and financial capabilities of the owners.
The strength of the roof will be assessed by specialists creating high-rise gardens.
170 kg / m2 must be supported by the structure on which the extensive garden appeared.
The load on a roof with an intensive garden is twice as much (350 kg / m2).
On our website you can familiarize yourself with the most popular projects of "small forms" for a private house - from construction companies represented at the exhibition "Low-Rise Country".
Planting specialists select plants that have adapted to high-altitude conditions.
The main requirements for the inhabitants of high-altitude beds and lawns:
the root system does not penetrate deep into the ground;
resistance to a long drought, the scorching rays of the sun, and frost;
they will not be destroyed by a strong wind ;
compatibility with each other.
The green roof often becomes home to grasses, stonecrop, sedum, and stone saberjewl. Even a simple turf on the roof turns a house into a work of art.
In extensive gardens, the tallest plants barely reach 30 see
Succulents feel great on the roofs (stonecrop, young, delosperm, aeonium). They are valued for their unpretentiousness: a small layer of soil and a little moisture is enough for them to be pleasing to the eye all summer. The main thing - do not overdo it with watering, the plants will die from an excess of moisture.
In addition to the succulents, the medicinal yarrow grows on the altitude, the wild flower Astra Alpine, the aromatic herbs thyme and oregano.
Bright daisies, a healing calendula, and tender cornflowers bloom on the roofs of private houses and country houses.
In the intensive gardens, dwarf shrubs and trees take root well. Heather, horizontal juniper, black chokeberry, viburnum, goat willow - many species were adapted to life at a height.
Professionals will prompt bright and unusual ideas for designing a high-rise garden or will help to realize your own fantasy.

Those who climb to the height of plants need the same care as those that grow on ordinary flower beds:
High-rise flower beds need to be watered if their inhabitants lack rain moisture. Automatic drip irrigation is preferred. Due to a thin layer of soil and winds, the water will evaporate quickly.
The turf laid on the roof periodically needs to be trimmed . Therefore, the lawnmower will have to work at height.
Grass and flowers growing in difficult conditions require dressing .
Weeds have no place on flower beds and lawns. They will have to fight in the usual "earthly ways".
Dead plants during the winter should be removed and planted new .
In winter the garden also needs the attention of the owners. It is necessary to remove the snow, because the supporting structures are under considerable load.
Eco-roof designers provide technical areas . You can move along them without fear of crushing the plants under the snow.
For the sake of your own safety, greening roofs and caring for high-rise gardens is better to entrust to professionals . They have the knowledge, experience and necessary equipment.
By choosing the concept of landscaping, using 3D visualization technology, you will see how the roof of a house or building will change.
After that, the professionals will prepare the drawings for the chosen landscaping option and calculate the cost of the work. The price of a grass roof depends on the complexity of the idea.
Companies that create roof oases do more than make a "layered" roof. By ordering roof landscaping, the client can include in the work plan:
system automatic watering ;
installing sculptures, bowls, arbors;
making fences ;
arrangement tracks ;
planting flowers, tree seedlings;
subsequent care behind the eco-roof.
Experts ensure that a soft roof will last for decades.
