Our green roofs

Realization of green roof

Hydroisolation and insulation of roofs, balconies and terraces is done by welding the PVC foils and melting the asphalt strips. On such hydroisolation it is then possible to apply paving, also usable on larger surfaces. We use PVC foils that are UV stable and certified against unwanted root growth.

What kinds of roofs do we install?

Extensive green roof:
This type of roof belongs to the least expensive and least demanding. It is a functional green growth with short vegetation such as mosses, succulents, various types of grass which create thick plant layer. The plants are xeric, they are growing fine on simple soil of 5-10 cm height.
The advantages of such roof is low price and low maintenance.

Intensive green roof:

The intensive green roof is more demanding to climate requirements. They also require higher weight carrying capacity and higher price. However, they are similarly esthetic as a normal garden would be. Thanks to the thicker soil layer (25-30 cm), the irrigation system and higher carrying capacity, they can host many more kinds of plants.

The advantages of green roofs:

Roof protection

The plant growth on the flat roof extends the roofs service life to basically unlimited amount of time. The soil and plants create a stable microclimate so the roof can be protected and servers longer.

Sound and thermoisolation

The plant leaves reflect and absorb the heat radiated in winter from the house. The soil protects the roof from wind which, in other case, could cause up to 50% heat loss from the house. In summer the green roofs keep the heat out of the building, even in case of extreme weather conditions.

Why green roofs?

During 20th century the green roofs became a typical quality modern urbanism feature. Their main purpose is to replace the green growth which was taken away by a building. The green roofs are not only esthetic but also functional feature which is beneficial for the building and its surroundings.

If you are planning on having a green roof, there are 3 conditions to keep in mind.
1. The roof has to be able to support heavy weight (depends on the roof type) – for intensive roofs the weight limit is higher than for extensive.
2. Next it is necessary to ensure a proper hydroisolation foil is used – so it would pass testing for FLL unwanded root growth.
3. Last but not least, it is needed to ensure a water drain from the roof.
We can help you adjust the conditions on your roof so they would match the above requirements.

Technology
The establishment of green roof depends on the weight the roof is able to carry, the landslide, etc. The roof always consists of several layers. The protective layer protects the roof and hydroisolation foil against damage. The drainage layer drains the water away and keeps the surplus water. The filter layer keeps the drainage layer clean from small particles from the soil.
For intensive roofs we use ordinary soil. Extensive roofs on the other hand require a stable substrate from porous materials with high drainage function such as ceramsite, lava or pumice.

Maintanance and service
As part of our specialised service we will take good care and plan your green roof maintenance. The extensive roofs require maintenance twice a year. The intensive roofs are similar to gardens and the maintenance frequency depends on the type of plants used. We also offer a professional counseling from the green roof project start until its realisation.

OTHER SERVICES

Rekonstruction of flat roofs

Majority of our orders are roof re-builds. It is necessary to avoid future complications during the planning phase. That´s why we recommend a consultation before roof build in order to think about the long-term best solution, even though the price would be higher.

Blending atics

Nowadays it is possible to buy high-quality tiling. However, the application of such has to also be done professionally. We use quality silicones and mastic, the screws are covered in colour too.

Replacement and installation of eaves

The old and rusty gutters dont last long and are the reason for leaking and seepage. Nowadays there are many quality plastic or varnished gutters made in variety of colours, from local or abroad producers.

Green walls

We cooperate with partners who have not only long year experience but also expert knowledge in the field. We use products of the company from Brno
