Green roofs provide ecological, aesthetic, psychological and economic benefits

Bituminous roofs with green roofs

Green roof - a green roof of a building, fully or partially covered with a layer of soil with vegetation. From this layer, the roof is waterproofed (waterproofing coating.

The fear that when winter comes you will have to hang out on the roof and clean the snow is also unfounded. If the house is sealed, does not waste heat, and the roof is well-insulated, the snow will not melt, it will act like a hat, which will provide additional thermal insulation.

An example of green roofs was the spectacular Gardens of Babylon. People soon noticed the benefits of green roofs - in the winter they kept the heat in the house, and in the summer they did not allow the heat to overheat the rooms, so they were pleasantly cool.

Although not the cheapest investment, green roofs are gaining popularity. A wide list of advantages is a great counterbalance to the higher cost of installing a roof.

Extensive roof landscaping

For low-maintenance plants that require a small layer of substrate, for example, weeding once a year is sufficient. As a rule, shillocks and other undemanding, low flowers, mosses, medicinal plants or simply lawn grass are chosen for this landscaping.

When extensively planting roofs, the plants selected must be long-lasting, resistant to cold, solar radiation, and drought. In the case of extensive greening of roofs, no irrigation system is installed, so plants that constantly need moisture are not suitable here.

Intensive greening of the roof

On the roof, a so-called garden is planted with a greater variety of plants, taller plants that require constant care (watering, fertilization, etc.). Perennial plants are used for greening, green lawn areas are also created, bushes and trees are planted. It probably goes without saying that such roof landscaping will require more investment.

The advantage of intensive planting is that you can create a unique corner of nature with paths, decorative bushes, even dwarf fruit trees. A green roof provides an opportunity for a new living space. The intensively greened roof with formed walkways, rest areas looks and can be used as a roof garden.

Intensive greening is applied to the roofs of business centers, cottages, and elite houses. Thanks to this landscaping, a unique corner of nature is created with paths, decorative bushes or dwarf fruit trees. The roof can be greened all or only a part of it, rest areas, children's playgrounds, etc. can be installed. Various plants are suitable for intensive greening of roofs: grasses, flowers, creepers, roses, low (2-3 m) trees and bushes. Dwarf fruit trees and vegetables are also grown. Plants should not be deeply rooted. Plants can be planted in troughs, tubs and directly in the substrate. When planting plants in containers, it will be necessary to take care of their wintering. Evergreens and conifers, as well as hardy native species, are suitable for hanging gardens.

 

Greening of roofs is an ecological necessity related to air cleanliness and the visual perception of the surrounding environment, which directly affects human mental health. Large roof surfaces are used to equip recreation areas, cafes, solariums, and sports complexes.

Green roofs have a calming effect, creating a psychologically comfortable environment. Roof greenery not only looks more beautiful, but also protects the roof covering from overheating and UV rays without additional investment, and extends its service life.

Green roofs have been around the world for a long time and are not considered strange or exotic, rather a necessity because they are harmless and have many advantages compared to conventional roofs.

The experience of greening the roofs of Scandinavia, Germany and other countries shows that additional investments in the installation of such roofs not only pay off, but also bring economic benefits. With the expansion of construction in cities, there is a shortage of green areas, and greening of urban roofs helps to solve most of the functional, economic, social and aesthetic problems.

Maintenance of a planted green roof

If watering is necessary, it is best to use a watering system (it is great if such technology has moisture sensors). Watered according to weather conditions. Fall and spring fertilizing and manual weeding are also important.

Maintenance of a green roof depends on the type of greening: whether the roof is greened extensively or intensively. If you don't want to invest your time in the maintenance of a green roof, extensive greening is definitely relevant for you. These roofs are completely maintenance-free. Plants are planted that do not have many needs.

What is different if the roof is greened in an intensive way. In this case, all shrubs, trees, decorative plants, flowers, and lawns will require care - according to the needs of each plant.

Green roof - what is it?

Regardless of which plants and other features of the green roof design you choose, your green roof will be breathable, ecological, aesthetic and, of course, beautiful.

Spring

The roof seems to come alive, becoming greener every day, full of life. It can also be impeccably neat and well-groomed or radiate natural disorder, embodying a single color or a wide color palette.

Summer

Fascinating with tiny dew drops in the early morning, lush greenery and/or a variegated blanket of flower blossoms. In autumn, golden autumn strokes give a fabulous view.

Winter

The green roof is usually not quite green - elegantly descended white snowflakes cover it with a thin white veil, giving it grace and a fabulous image.

Advantages and disadvantages of a green roof

Green roofs really look very aesthetic, exclusive. But it's not just visual aspects that dominate their list of benefits – green roofs have a solid list of economic, ecological and other benefits.

Traditionally used roof coverings absorb the sun's rays and release them back into the atmosphere as heat, resulting in urban temperatures typically at least 4°C higher than surrounding less urbanized areas; it has been estimated that if all the roofs of a large city were green, the temperature in the city would be about 7C cooler on a hot day.

Additional space is created for building users

Green roofs give residents the opportunity to establish recreation areas and a park in a very convenient location. You won't have to look for a place in the park because you can create one in your own home. Children's playgrounds, recreation areas, terrace areas or simply watching movies in the open sky can be established in such spaces. You can grow fruits, vegetables, flowers. Restaurant in industrial facilities.

Reduces the energy consumption of the building's indoor temperature and maintenance

In the cold season, this allows you to significantly reduce heating costs, while in the summer you can save by incurring lower costs for conditioning the building. Green roofs "get along" perfectly with solar panels and complement each other's advantages. Green roofs do not heat up even on hot summer days, which leads to the maximum efficiency of solar panels, since the latter is extremely closely related to the ambient temperature.

Holds a large amount of rainwater

Rainwater, as we know, is not a friend to roof coverings. However, this is high humidity, and the latter negatively affects the properties of roof coverings. However, green roofs prevent this, as the vegetation layer retains up to 90 percent of the water. rain water! A large part of it is consumed by plants, and the rest simply evaporates. For this reason, not only will the roof structure be protected, but you will also be able to install a simpler and cheaper rainwater collection system.

Protects the roof and extends the service life

It's no secret that ordinary roofing is affected by external influences, which have a negative impact. The plant cover effectively protects the roof structure from environmental factors such as sunlight, strong wind, temperature changes, etc. The entire plant layer reduces the negative influence of temperature changes many times over and has a positive effect on the waterproofing of the roof

Creates a cleaner environment

Vegetation filters pollutants and CO2 from the surrounding air; pollutants and heavy metals from rainwater. Green roofs can capture up to 75% of rainwater, which is then returned to the atmosphere through transpiration, while pollutants in the rainwater remain in the soil.

Improves sound insulation

After installing a roof with a conventional coating, many people complain about the sound of raindrops hitting it (especially relevant in the case of tin roofs). Those who live in busy areas of the city, near airports and railway stations really have a hard time putting up with the noise coming from outside. That's it - green roofs perfectly absorb sound and greatly improve sound insulation. Green roof - cleaner air. We all know that plants help filter the air, trap dust, and clean the environment around the house.

Disadvantages:

  • Stronger and more expensive structures are required, as the roof must support a significantly greater mass.
  • The more intensive the form of landscaping, the more maintenance of the roof and additional ergonomic equipment is required;
  • Not all plants growing in the region are suitable for planting.
