In the 19th century, the famous mason and inventor Karl Rabitz surprised visitors to the Paris agricultural exhibition. He presented the “living roof” device to the sophisticated public. Instead of the usual red tiles of that time, it was a cozy garden, the dream of any romantic lady. So people remembered green roofs, which are still primitive people could create with their own hands, escaping from the cold and rain. Periodically, one or another architect recalled this direction and introduced elements natural design roofs to your facilities. But today there is a powerful wave of people wanting to turn their roof into a green corner of nature. What does a lawn on the roof provide and how to implement the idea with your own hands, we will try to answer in this article.

A lawn on the roof of a house significantly saves space.

Green roof - the moment of truth

The structure of the roof in use, except for getting into fashion trend, provides its owners with the following advantages:

Lawn laying scheme.

  1. Space saving. Just imagine that having a house with small area land, you can carve out a place for cozy corner nature. Sitting at a table and drinking tea, you can admire the emerald greenery smooth lawn or, without fear of glass, walk on it barefoot and do your favorite yoga right on it.
  2. Environmental friendliness. You don’t have to be a member of Greenpeace to understand how much benefit it brings. Sometimes in a metropolis it can be the only source of clean air; only plants can produce oxygen. In addition, contact with living nature has a beneficial effect on human well-being. This eco-friendly roof can be equipped with solar panels to provide owners with cheap electricity.
  3. Moisture absorption. Atmospheric precipitation after the device grass roof not harmful to the roof structure. More than 60% is returned by evaporation to environment, the remaining 40% is absorbed by plant roots.
  4. Thermal insulation, sound insulation. Plus green roofs. Reliable thermal protection, you feel good in summer and not cold in winter. The grass layer is a living wall that protects roofing materials from ultraviolet rays. Such a roof is fireproof and soundproof, and is a natural air conditioner.

Stages of building your own oasis of nature on the roof

Flat roof – perfect option for creating a green corner with your own hands.

Cultivation of natural objects on it can be either extensive (placing flowers in outdoor pots on summer period), and intensive (creating natural garden plot). But the hardworking Germans learned to arrange green spaces on tented, lean-to, gable roofs According to the latest technologies, the only condition: the slope of the slope should be no more than 45°.

So, let's get started, the first condition: the roof structure must withstand from 100 kg/m² to 700 kg/m², depending on the type of planting. For a lawn, the first value is sufficient; it will be discussed further. What do we have to do?

Green roofing additionally creates heat and waterproofing of the roof of the house.

  1. Create a waterproof layer: clean the roof, lay waterproofing, create a hole for water drainage.
  2. Protecting the roof from root growth: laying fleece + hole for water.
  3. Drainage device: filling with gravel, expanded clay, etc. (layer from 10 cm) or installing a special polymer drainage pad + hole for water.
  4. Cover with soil: distribute the layer evenly (for a simple lawn the layer height is 5 cm, for a full-scale garden 1 m).
  5. Add fertilizer.
  6. Sowing: mix the seeds with sand and scatter them evenly over the area, holding the container with the seeds in your hands, like the ancient plowmen. We moisten the emerging shoots daily for 3 weeks. The rooftop lawn is ready!

If you decide to decorate your roof with a professional roll lawn yourself, then you take more risks, but spend less money.

A small reminder for the owner of a rolled lawn:

  1. Possible timings: April-November.
  2. The assembly and laying of the field must be completed within three days, otherwise there may be rotten areas with yellow grass. The rolls are laid in a checkerboard pattern with careful joining of the seams.
  3. Soil for roll lawn must be loosened and fertilized.
  4. Mowing: 7 days after laying.
  5. Feed once every three to four weeks.
  6. Recommended autumn processing from fungus. Fundozol solution ( Matchbox per bucket per 1 sq.m.) thoroughly spray the lawn area.

Characteristic features of the owner’s nature country house or dachas can be called the desire to improve one’s possessions and an insatiable craving for creativity, ultimate goal which is all the same improvement - a plot, a house, utility and utility rooms.

Green roofs- a topic loved by many. What makes this process even more interesting is the expansion of its scope. Over the past few years, it has been gaining popularity in “suburban” Russia. new trend- landscaping... roofs! However, everything new, as we know, is just well-forgotten old. Such floristic delights could be found several centuries ago in northern Russian villages, and in the Baltic states, and in Finland: roofs were covered with moss and turf not at all in pursuit of beauty - this is how they insulated and strengthened the roof, but thatched roof saved from fire (due to overheating in the sun) and rotting (exposure to dampness).

What motivates green roof enthusiasts today? The answer is obvious: this is an extension usable area site through the use of other surfaces, and the creation additional places for landscaping, and the opportunity to give the house (barn, pergola, etc.) a non-standard appearance, and even the creation of new recreation areas.

Extensive roof greening method

This method has 3 features:

  • inability to walk through green spaces;
  • the maximum permissible surface slope is 28 degrees.

Irrigation of the surface plays a huge role - if an artificial irrigation system is not provided, take care of the convenience of delivering water to the roof (hose, watering can, makeshift shower).

The main “residents” of the roof are: lawn grass, sedums, saxifrages. You can also plant bulbous ones. Main principle- planting plants that require minimal care and blooming in different time. With a successful selection, you can get a garden of continuous flowering.

Extensive roof greening can be done on your own. Evaluate the surface being treated. What is its condition: how reliable is the foundation, what load can it withstand, what is the quality of the roof? Think about the location of the future oasis. It is necessary to take into account the direction of the light, illumination, intensity " sunbathing", openness to winds and precipitation. Choose plants to plant with this in mind.

In addition to drought, there is another enemy of the roof garden - stagnant moisture. IN in this case it not only harms plant roots, but also significantly increases the load on the load-bearing surface. So for roofs with a slope of less than 4 degrees you will have to equip drainage system. Or forcefully form the desired slope.

Preparing the roof surface for landscaping

The base is treated if necessary special compounds: primers, fungicides, water repellents. Then a root protection film is placed on it. Remember how a seed blown by the wind onto the roof of a building grows into a decent-sized tree, mercilessly crushing even granite with its roots. The film will allow the roof to avoid this fate. The geo-fabric or can help reduce the load on the roof and avoid soil sliding.

The basis for planting is usually fertile layer or substrate (layer thickness 5-20 cm). The mixing of soil and drainage layer that occurs over time will be avoided by separating them with a thin geotextile. The roof slope must be well reinforced. At a large angle of inclination, it is possible to prevent the vegetative layer from sliding by using geogrids.

Intensive roof greening method

It is usually carried out by professionals. This comes with a serious responsibility: the load per 1 sq. m of surface with intensive landscaping ranges from 150 to 750 kg. Accordingly, the basis is presented increased requirements. On landscaped area It will be possible to lay out not only an ordinary lawn, but also an entire park - with trees, a pond, streams. You can put up a gazebo and lanterns, lay out paths. Lushly blooming and exquisite mixborders will delight the eye all season. A automatic system watering will solve irrigation issues.

Experts recommend landscaping immediately after completion. construction work. It is better if the creation of a roof garden is included in the design project - this will avoid disharmony with the main landscape and architectural appearance of the main buildings.

The concept of a “living roof” appeared recently, in late XIX century in Paris. People liked the vegetation on the roof so much that now everyone can arrange a similar miracle for themselves. Designers use a special term “ green roof", which is increasingly gaining popularity and distribution throughout Europe, and our country is no exception. Therefore, if you want to equip a green corner, then you should read this article, which discusses information on how to make a lawn on the roof with your own hands. According to experts, you need to be patient, have a small budget, and also have a lot of desire, and then the result will please you.

Advantages and features of a green roof

Advantages and features of a green roof

In addition to the fact that this element is all the rage these days, and every person dreams of equipping it at home, there are a number of other advantages of a green roof:

  • Saving space. A living roof is an ideal option for those who do not have land plot or it's too small. If the roof is securely reinforced, then you can safely walk on the lawn, do yoga or relax.
  • Ecology. All materials that are used for the construction and installation of the roof emit when heated harmful substances, but if it is covered with a green carpet, then this problem will be canceled.
  • Electricity generation. If finances allow, then in addition to a lawn on the roof, you can install solar panels, which will supply the house with electricity, which will lead to significant savings in resources.
  • Moisture absorption. Almost all the moisture that falls on the roof during rain will be absorbed into the soil, and with good waterproofing you don’t have to worry about roof leaks.
  • Durability. At making the right choice plants for greening the roof can extend the service life of the roof several times, since a sufficiently large layer will reliably protect it from the influence of ultraviolet radiation and precipitation.
  • Additional heat and sound insulation. Thanks to the greening of the entire roof area, you can immediately notice a reduction in noise coming from the street, as well as comfortable temperature in the rooms.

Since the sun's rays will warm up the lawn, the soil, and only then the roof, the rooms in the house will not heat up, and in the summer heat a comfortable microclimate will be created.

Main types of green roofs

Main types of green roofs

Before developing a green roof, you need to familiarize yourself with the types of vegetable roofs.

Types of roof landscaping Extensive is a lightweight option that uses a small layer of soil up to 15 cm high. When choosing plants, preference is given to those that are unpretentious and do not require special care. Landscape designers They recommend evergreens, carpeted. This option is suitable for light structures, roofs summer house, gazebos, garage.

Intensive - a complicated option, during which it is necessary to strongly strengthen rafter system to create a roof garden with a lawn, paths and even a gazebo. Shrubs, small, ornamental or exotic trees, lighting is being done. The thickness of the soil must be at least 1.5 m in order to root system developed well.

Flat or pitched roofs. The ideal site for creating a lawn is flat roof, on which you can arrange an intensive version of landscaping. On pitched roof A simple lawn will also look beautiful.

In many modern multi-storey buildings and business centers, the roof is covered with intensive landscaping with a swimming pool. To develop such a project, you need the help of a specialist.

Preparatory work

Preparatory work

At the first stage, it is necessary to strengthen the entire roof of the house so that it can withstand heavy loads. After this you need to treat the surface various compositions by type of primers or water repellents. To protect the material from exposure to soil and high humidity lay a root-protective film, in addition, it will protect against the soil sliding down.

When choosing soil, you should give preference to a fertile substrate in which plants will germinate quickly. It is also worth using a geo-textile that will separate the drainage and the soil so that they do not mix.

Green roofing compositions

If the roof has a large slope, geogrids should be used to prevent the vegetative layer from sliding down. You can purchase them in specialized stores.

Step-by-step instructions for creating a plant roof

Step-by-step instructions for creating a plant roof

Since the lawn on the roof is not new technology, then we can say with confidence that today exclusively durable and safe materials, and the installation process is quite simple.

  • To create a lawn on the roof, you must have a solid foundation in the form of sheathing or concrete floor, so if your roof is covered with tiles, then it needs to be disassembled. A flat and even slab is also not suitable, it is necessary minimum slope at 5-10° so that excess moisture goes to the drain.
  • After this, you can proceed to the main layers. First, protective waterproofing is installed to prevent moisture from rain and watering from entering the house. Polyethylene film or liquid rubber laid on the roof surface and secured with screws.
  • The next step will be laying the thermal insulation layer, which consists of cork slabs. They are laid end to end using special glue.
  • Protection against root formations, which are quite actively developing in good soil, which means they can damage the roof. In specialized stores you can find waterproofing materials with root protection.
  • In order for water to be retained and constantly nourish the plants, a drainage layer is necessary. For these purposes, expanded clay is used, which can be found in any hardware store and it's inexpensive. Geotextile filtration is also installed to prevent the drainage from becoming clogged.
  • To securely fix the soil, use a sheathing that will retain all the soil. In most cases, a plastic geogrid with low weight is used.
  • When choosing soil, you need to carefully study all the plants that will grow on the roof. A regular lawn requires a small layer of 10 cm. Do not forget that a suitable base should be porous and light.
  • The waterproofing layer should be as durable as possible; it is better to lay it in two layers. If a defect appears somewhere, then it will have to be re-laid over the entire area. When choosing moss for roof landscaping, you can skip the insulation layer, since this plant performs all the functions of thermal insulation.

    The video shows the phased construction of a green roof:

    Green roofing of buildings is becoming increasingly popular around the world. This trend is especially common in Europe and is popular among owners of business centers and hotels. In Russia, this type of building decoration is still poorly developed, however, more and more owners, paying attention to the West, are trying to give their buildings unusual look through rooftop lawn plantings and a variety of plants. How to make a lawn on the roof so that it is pleasing to the eye and does not cause problems in the future? The answer to this question will be the article you are reading.

    Types of landscaping

    Turning to the issue of arranging a lawn with your own hands, you should immediately note that before starting work, you need to take into account several important points.

    1. The roof structure must be reliable enough to withstand the weight of such a design; if in doubt about this, it is better to contact professionals who will assess the strength of the building's roof.
    2. Need to calculate correctly own strength and finance. If you plan to take all the work into your own hands, then it is better to first try to lay out the lawn on small surfaces, for example, on the roof of a booth, shed or garage.

    These two points determine which roof greening path you choose: extensive or intensive. If you plan to do all the work yourself, spending a minimum financial investments, the extensive method will suit you, but it is important to consider that the roof of the building must be horizontal, although this moment German technology created plant mats that replace the soil layer and are capable of growing at a slope of up to 45 degrees. The extensive method implies a relatively small load on the roof of about 20 kg per 1 m².

    The procedure for creating extensive landscaping

    1. The technology for creating extensive landscaping is that it is necessary to remove everything from the roof. roofing materials– tiles, slate, leaving only the concrete surface, which must first be prepared: provide a slight slope towards the drain, for example, using a sand-cement screed.
    2. Don't forget also about a permeable barrier around the perimeter of the roof, which will not allow the soil to slide, but will still allow water to drain.
    3. One of the most important stages roof arrangement - waterproofing. It is extremely important to use high-quality waterproofing materials here, otherwise in the future it will be necessary to raise the remaining layers of the green roof to eliminate leaks.
    4. After waterproofing, the roof surface is thermally insulated using materials such as polyurethane or balsa wood, and then the roof is laid protective film(membrane), for example, non-woven polypropylene, which prevents roots from growing into the roof.
    5. After this, geotextiles are applied, and then a drainage layer of 5–7 cm is applied. For drainage, you can use, for example, pumice or expanded clay gravel.
    6. The next layer is the soil itself, 5–20 cm thick, depending on the needs of the plants. To plant plants on the roof, a special lightweight soil is used, which usually includes sand, peat, shale, and tree bark (ordinary soil from a personal plot will not work).

    The process of creating a living roof can be simplified if you place containers, flowerpots or pots with already planted plants on a surface that is waterproofed and protected from root growth. This will greatly facilitate not only the process of greening the roof, but will also help in the future when caring for plants, as well as if it is necessary to repair the roof or change the landscape.

    German companies have simplified the creation of a green roof by releasing a special ready-made roof lawn, which already contains all the necessary layers.

    With the extensive method, plants with a small root system can be planted in the ground. Will fit different kinds lawn vegetation such as:

    • ground cover plants;
    • plants with fibrous root systems;
    • meadow and bulbous grasses and flowers.

    For example, they will feel good:

    • saxifrage;
    • alyssum;
    • oregano;
    • carnation;
    • lavender;
    • bell;
    • sedum

    You can plant shrubs and trees, but these must be dwarf, ornamental species. When choosing plants, also keep in mind that growing on a roof is similar to conditions on a hill or in the mountains - plants are exposed to direct sun rays and winds. At correct selection plants in accordance with their growth, flowering, as well as with optimal watering, fertilizing and regular cutting, your living roof will delight you for a long time, and the flowering of some plants will be harmoniously replaced by the flowering of others.

    Intensive technology

    Intensive roof greening technology is more expensive from a financial point of view, but the result is much more impressive. The embodiment of this technology can be seen on the roof of a house, hotel or restaurant, where not only lawns are grown, but also shrubs and even small trees, there are recreation areas, paths, playgrounds, and swimming pools. Landscape design specialists know how to create such splendor professional builders, in this case it is better to resort to their help.

    With this technology, the weight of the finished landscape reaches 700 kg per m², so it is necessary professional assessment capabilities of the building and its roof.

    So you can make your wildest desires come true and place:

    • benches;
    • sculptures;
    • fountains;
    • ponds and streams;
    • lanterns;
    • figured barriers.

    When creating such a roof garden, a system is immediately provided automatic irrigation. Professionals recommend starting greening the roof using intensive technology immediately after finishing the construction of the house, and the best option It is considered to include a green roof in the building design.

    Greening a roof is quite labor-intensive and expensive from a financial point of view, but the result exceeds all expectations. You get a well-insulated, fireproof, protected from leakage and overheating, a beautiful building roof equipped with additional sound insulation and, of course, admiring glances from your neighbors.

    In this video you will get acquainted with the plants that are best suited for creating a lawn on the roof and find out what you need to perform such roof landscaping:

    In this video, the roof of the gazebo is being landscaped, pay attention to how this is done:

    For the last few year s fashionable option landscaping is the installation of lawns on the roofs of objects. This can most often be seen in European countries. In Russian cities, this method of decoration is still poorly developed, but is gradually gaining momentum. How to arrange a lawn on the roof so that it can be pleasing to the eye?

    Different types of landscaping

    When deciding to arrange a lawn on the roof on your own, you should take into account some features.

    The roof structure must be quite strong to withstand the additional load. If in doubt, contact a professional to determine the strength level. Now decide on your strengths and cash. Having decided to do everything on your own, we advise you to conduct an experiment on small area- shed or garage.

    These conditions will determine which landscaping method you choose – extensive or intensive. If you decide to do everything yourself to save money, use the first method. It is important that the roof is horizontal. But today, German technologies have developed special mats that can replace the soil and be located on a slope of forty-five degrees. When performing this method of landscaping, the load forces should be distributed about twenty kilograms per square area.

    We create extensive landscaping

    The technological features of the method are that all covering materials are removed from the roof - slate, tiles and others. All that remains is concrete surface, which is pre-prepared by arranging a slight slope towards the water drainage. This can be done using a cement screed.

    Do not forget that it is necessary to install a permeable fence around the perimeter of the roof to prevent the soil from moving. Another one important detail– waterproofing layer. It is recommended to use the most quality materials to avoid future water leaks. Having created protection from water, a heat-insulating layer of polyurethane or balsa wood, a protective film of non-woven polypropylene is laid, which does not allow the roots to grow into the roof.

    Now geotextiles are applied, then a drainage layer with a thickness of five to seven centimeters is applied. Expanded clay or gravel is suitable for its arrangement. Now it's pouring ground layer, about twenty centimeters thick - it depends on the plants that will grow there. A mixture of sand, peat, slate, and tree bark should be used.

    The process of greening a roof can be simplified if ready-made containers with already planted plants are installed on a surface protected from water penetration and root ingrowth. This will make it easier to care for them and not have to extra work if you need to carry out roof repairs.

    It should be noted that German manufacturers The process was simplified by producing ready-made lawns consisting of the necessary layers.

    This method is suitable for planting ground cover plants, meadow and bulbous grasses and flowers, plants with fibrous roots. It is recommended to use saxifrage, oregano, cloves, lavender, and bellflower. It is allowed to plant shrubs and dwarf trees.

    Please note that on roof slope the plants will grow as if on a hillside. Having correctly identified the varieties and organized everything the necessary conditions, you can create a solid green carpet on the roof.

    Intensive technology

    This method is more expensive, but more effective. Such methods are used on the roofs of hotels, houses or restaurants, where not only lawn plants can be grown, but also shrubs and small trees. As a rule, such roofs provide seating areas, playgrounds and even swimming pools. Creation of such design solutions should be entrusted professional craftsmen, having everything necessary secrets arrangement.

    With this method, the load of the finished landscape on square meter will be about seven hundred kilograms, which is quite significant.

    When creating such a garden on the roof, you should immediately provide a watering system. Craftsmen advise starting landscaping work on the roof immediately after building a house. It is best to initially provide for such solutions in design solutions.
