Green Roofs In Urban Areas – Why And How?

Ecological commitment

By the end of the 1970s, the notion of green roofs concerned only intense roof gardens. Experience in the cultivation of these areas over the last 15 years has resulted in many discoveries and findings whose application has yielded great results in the design of green roofs of outstanding design.


The expansion of extensive roof gardens is the result of a significant change in attitudes over the past ten years. Ecological aspects of design have a growing impact. The demand for a lower price and the popularity of low-load roofs went in the direction of extensive green roofs of less thickness, specific composition, cheaper installation, and maintenance.

Ecological commitment

Fridrich Stowaser, nicknamed Hundertwasser (1927-2000), is one of the first architects to point out the importance of green roofs: green architecture could be one of the ways of this non-aggressive resistance. He perceived nature as a sublime reality, a source of universal harmony. His great respect for nature appeared in the desire to protect her from her greatest enemy – man.


Hundertwasser distinguished himself in his ecological commitment and felt that the appearance of each building should be conditioned by the aesthetic principles of his tenants. Hundertwasser’s house with a grassy roof in Vienna in 1985 is a physical manifestation of return to nature. Every free area on this house is filled with greenery, above all of the trees that Hundertwasser considered as equal occupants. The green roof is also related to his inventions of humus toilets and tenant trees.

One of the newer examples of a green roof building is the Green Citadel in Magdeburg, completed in October 2005, built according to the latest Hundertwasser project. In spite of the name, the complex is pink in color, and it consists of 55 apartments, hotels, and shops.

Why the Green roof is placed

Green roofs should become an integral part and regular phenomenon in the green area system of all regions. This type of roofs is worth the living space of insects and birds. The microclimate around the building is improving because the roof covered with greenery is less heated.

The large part of the rainwater is first retained on the roof and then gradually evaporated, unlike other roofs that immediately lead the water to the sewage system, and the evaporation of the remaining water is rapid (which in the short time creates a high degree of moisture saturation).

Also, the plant cover extends the lifetime of the roof insulation as it protects against large temperature fluctuations. However, the green roofs are a privilege of the population of countries with developed ecological awareness, as well as a culture of cultivating green areas.

Routine Controls And Repairs Of Flat Roofs


Since most flat roof problems arise from the inability to find the exact location of the minor defect and to repair it at an early stage, roof inspections must be performed on a regular basis. It is recommended that you do this two times a year, in the spring and autumn (fall), and to record the condition and any changes observed, for you to get the better understanding on how does your roof changes over time. In that way, you can prevent any defect no matter how minor they can be.


These can be wrinkles, bubbles, drainage problems, torn material, cracks, holes, openings or waste and shocks that sometimes accumulate even on the roof. It is important to check the roof during light and heavy rain to determine if and to what extent and how long the water is retained on the roof. During the check, it is necessary to look at the interior walls and ceilings. Inspection of flat roofs in developed countries is done even with infrared cameras, night shots that accurately show damp places invisible to the naked eye, which are cooler than the rest of the roof.

If you find a problem

If the problem is diagnosed in time, it can save you significant money, before greater intervention becomes necessary. The openings can be filled, the missing material is added, and if there is a problem with water retention, the possible solution is to increase the inclination of a flat roof. Water retention was most often solved earlier by placing layers and paper and aggregates on existing layers, while today bituminous coatings can be used for such minor repairs.


It is also very important to regularly clean the vegetation that appears on the surface itself, as the plants create and expand cracks and weak spots, and retaining water increases the moisture and danger of leakage. A special case of a favorable solution for a flat roof with the use of vegetation are the roof gardens which will be more words in other articles.

When, after a predetermined amount of time which can eventually be extended to a certain extent.

The roof expires, the anticipated lifetime expires, and besides the alignment, there are leaks, instead of adding a new layer, it is recommended to replace the whole flat roof, possibly with some of the more modern solutions.

The Economic Advantages Of Green Roofs


The economic benefits of green roofs can include the possibility of reducing the quantity of necessary equipment, standard insulation equipment, use of cooling systems, the ability to reduce or even eliminate the roof drainage (drainage pipes, drains, gutters), possibility to regulate all requirements for rainwater and other precipitation management.

The mentioned advantages of green roofs can be explained by the fact that vegetation absorbs a large amount of precipitation water that it uses for its growth and development while reducing the need for roof drainage. On the other hand, the plant’s transpiration and evapotranspiration process play a role in reducing air temperature and reducing the use of standard insulation equipment, refrigeration and heating systems.

If there is widespread use of green roofs, expansion of companies, professional highly qualified and qualified profiles specialized for the production of elements for the formation of such roofs could be achieved: roof membranes, irrigation systems, substrates, plants, water purification systems, temperature and humidity control... This would also include many professionals: designers, architects, and architects of landscape architecture, whose specialization in this field would be of great importance during construction and adaptation.

All this would lead to the creation of new jobs for lower-skilled workers, to the launching of the supporting industry and education systems, and to the general increase in environmental awareness and culture that would extend to other fields of human activity.

Saving the community

Greening the roofs can help save the whole community by reducing the need for health services. Green areas reduce harmful substances that adversely affect the ozone layer, and directly to human health (especially respiratory organs). They positively influence the increase in creativity and labor productivity thanks to the possibility of a passive experience of nature and vegetation.

An analysis of the relationship between invested funds and profit is one of the possible ways to properly explain the positive effect of greening the roofing surfaces on the economy of a region.


The aesthetic function is a sufficient reason for the formation of a green roof because as an effect of the beautification of the city landscape, it significantly affects the quality of life in urban conditions. Greened roof surfaces positively affect the satisfaction of the erotic needs of people who are employed in facilities that look at the green roofs of buildings. Research shows that people who worked in rooms with plants or with a view of the green surface have a 12% higher productivity than those who did the same job in premises without any contact with plants.

This approach to the use of plants in the workplace also has a preventative effect because the onset of illness in employees can be due to stress and mental fatigue, rather than the consequence of unhealthy work environment conditions.

4 Security Issues Caused By Leaking Roofs


Too many people underestimate the damage that may be caused by a little leak. Of course, at first, it looks harmless, and the bucket is so easy to set up below to solve the problem, right? This kind of thinking can lead you to great trouble, as most small, harmless leaks develop into much bigger problems.


If you are unsure about whether you can deal with the problem of leakage, you should always contact the professionals. They will be able to tell you how much time does it takes for the problem to be resolved and how to prevent the occurrence of any future leaks in that same place.

  1. Water can be a fire risk

Although it may sound ironic, water can pose a fairly high fire risk in the house. This is because of all the electrical installations that are present in your home. Water is a very good conductor of electricity, and that can cause a fire, or harm your loved ones. You can never know how far the water came from the leak in your roof to your other rooms, installations, in the attic, ceiling or walls.


To be safe, you should always turn off electrical power in parts of the house affected by leakage. This will prevent the appearance of fire and will help to avoid short circuits. You need to have the electrician who will examine the area where the leak is reported to make sure are there or are there not immediate concerns that you or the roofing contractor are unable to identify.

  1. Leaking is not healthy

Leaking is a health problem for you and your home. This is because water can easily go into the woodwork, creating a perfect shelter for the mold. Breathing air filed with mold is very dangerous and should be avoided at all costs.


Mold can cause serious lung problems and allergies. If you notice dark spots or some darkened places anywhere on the ceiling, there is a high likelihood that the surface is under the influence of water and that it began to rot. Wooden construction can also be weakened, and that is quite dangerous.

  1. Slippery floor

Many times this security issue has been called as overestimated. Older citizens and children are particularly vulnerable to slipping on water which can cause major health problems, depending on the severity of the fall.

Although this can be hard work, we should clean the area affected by leaks (if it gets to the floor) to avoid unwanted injuries.

  1. Other problems

Leaks that are neglected and left to themselves for a long time can destroy the house. The fall of the ceiling is possible, and if the prolongation lasts for a long period and you notice real damage, it should be repaired as soon as possible. The ceilings will not warn you much before the fall, except perhaps the dark spots that we have already mentioned.

Reasons Responsible For Roof Leaks

Roof Leaks

If you discover that you leak in your roof, you are potentially exposed to the danger of significant water damage and other problems if you do not deal with it. Leaking does not have to be understood just as seriously, and sometimes a solution to your problems will only be a bucket. But leaking, too, should not be underestimated because of the amount of damage that it can cause. In this article, we will deal with some of the reasons why the roofs can leak.

  1. Roof windows can be a problem

Although the built-in skylights can make your home more attractive and more beautiful, the release of natural light inside, when they are not built properly can cause a lot of problems. If they are too old, they can easily let water inside the house.

Some types of materials cannot withstand too much weight and load, so water from the rain can over time find the way through. You need to check your windows and the area around them regularly, because if you don’t, you may find you have a problem when it is too late or too much damage. Repairing that problem can be expensive.

  1. How old is your roof?

Stop for a moment and think about how old your roof is. How many years have passed? How good was the last contractor? Roofs built 50 years ago were made with many different materials and were much less durable than the materials used today. Every professional should know exactly how many years your roof will last, provided there are no accidents or terrible storms.

  1. Check the roof cover and gutters

Materials such as roof coverings and gutters can easily be damaged or shifted during heavy storms or strong winds. The water can easily go under the lower layer of the roof and then find its way to the inside of the house.

Also, in the case of strong winds or storms, the gutters can be displaced, and the water from the roof can start to leak everywhere. Solving these problems is relatively simple. At the end of the storm, check the roof cover and gutters, and if there are too much-damaged parts of the roof cover, replace them.

  1. Is the roof well executed?

Some people are lucky and able to hire professional performers who have a lot of references behind and a bunch of experience. You only employ others based on their words. For this reason, many roofs are extinguished – they are not well executed!

To avoid the whole problem, never employ someone without checking his experience, references and whether their previous clients were (and still are) satisfied.
