Making a roof over a balcony. Roof to balcony or loggia. How to make a roof on the balcony of the last floor with your own hands

But rooftop gardener Geitlinger knows: Fifth-floor gardening is different from "normal" gardening in many ways. For example, in irrigation. Geitlinger is often absent, she works as a nurse and loves to travel; An irrigation system is needed. The first plant turned out to be unusable: it sprinkled water half a meter above the ground - the wind blew it away.

Cutouts throw them in the street

It's also a little tedious that every bag of soil and every seedling has to climb a ladder. For the greenery, she had to develop a recycling system with the landlord: First, she tosses the clippings onto her deck below, from there onto the impact-resistant roof of the bike rack before the city's shredder can pick up the branches. A rooftop garden is nothing without a homeowner. According to the Code of Commitments, his written consent is a prerequisite. And it needs to be regulated exactly what happens after the end of the lease with structural changes - regardless of whether the owner takes the garden and compensates the former tenant for the investment, since the garden is an added value.

Otherwise, it may require restoration of the original state. Even homeowners cannot create a rooftop garden on their own. As a rule, they have the right to use only terraces and roofs. If appearance change - as in the case of a roof garden - the household must give its consent, the Civil Code says. In addition, the cantonal and municipal building law must always be taken into account: if the maximum building height has already been reached, for example, it is hardly possible to install a hedge or install a railing.

"Mathematically it doesn't work"

Fischer befriends her, he let the garden create and act like a builder, she rents an apartment and a garden. Because the garden is only accessible through Gatelinger's apartment, it cannot be used by other tenants in the house. Though Maya Geitlinger's green oasis is at dizzying heights, it's nothing but isolation. Again and again the seeds of wild plants find their way into the garden. For example, the ivy that weaves around the elevator shaft just grew, and because it was just fine, she let it.

Thanks to the warmth of the house, the roof garden is quite frost-resistant. It is also so warm in summer that fruit can ripen very well - 23 kg of plums picked by gardener Geitlinger last year. It's also like being in a "real garden" - it's impossible to talk about a garden fence; far and wide there is no other roof garden.

What materials are suitable for building a balcony roof

However, green roofs. Since the nineties, their number has increased dramatically. Basel pioneered subsidies: Today, one in three flat roofs in the city is green - covered with a layer of depleted substrate and colonized with heat-tolerant and drought-like plants such as sedum species, thyme and house. “This saves energy,” says Stefan Brenneissen, head of the Green Roof research group at the University of Applied Sciences Zurich. “The building does not heat up as quickly in summer due to the extra layer of insulation, but at the same time, less heat is lost in winter.”

In addition, the waterproofing of a green roof is longer. “And the plants have positively impacted the urban climate and are nice to look at.” All the reasons many municipalities are now dictating green new flat roofs. This may be the first step towards expanding rooftop gardens. According to Stefan Brenneusen, the waterproofing of sheet flat roofs is also sufficient for a real garden - provided the design allows it. Thus, there is potential for more oases on the fifth floor.

There are various systems for sealing and landing roofs. He showed that he could be loaded with 500 kilograms per square meter, in the regional area even from a ton. It is not exhausted by today's garden - but it also always requires some reserve, because snow is also important in winter. Print: a vapor barrier appeared on the concrete roof, and then thermal insulation. With wooden beams for rainwater, different depths were created. Where the pools are deep and a lot of water is collected, there are now wetter areas of the garden. On the beam frame came a five-centimeter-thick concrete cover that serves as a mechanical protection so that the seal is not broken when gardening with a shovel. Now it's down to the actual garden floor: first, a layer 5 to 15 centimeters thick with expanded clay beads, filled with fleece covers so that the earth doesn't mix with it. Rainwater can collect in this layer. There was also a special garden substrate on the roof that acts as a layer of humus. Depending on the location, it is 10 to 30 centimeters deep. An additional stable mesh fence was built around the roof garden.

• The civil engineer calculated the bearing capacity of the roof of the house.
• It was covered with bitumen and laid roofing.

They then release it, creating the so-called island heat effect, which is usually the reason why living in a particular city is hotter than living in a cool garden. Just thinking about it in the past, this is what they were created, which in a nutshell is explained by the roofs covered with vegetation.

What is a green roof for? The main one is to provide green or vegetal vegetation in cities, which provides various benefits. For example, absorb greenhouse gases such as carbon dioxide. Plants also clean the air of other urban pollutants.

They also absorb sound, so they reduce the noise pollution typical of urban environments. As we said, they avoid the heat island effect by functioning as thermal insulation, so they end up saving energy because they keep you cool in the summer. And this is not cool, they can significantly reduce the temperature of the building.

But what is a green roof? There are many styles and forms, semi-intensive, intensive and extensive, depending on the depth of the planted soil, the environment where they will be planted, or whether there will be soil for the plants. Typical rooftop gardens require a reasonable depth of soil to grow large plants or herbs and are considered intensive because they require a lot of maintenance, irrigation, etc.
