We carry out all kinds of works related to flat roofs – construction, repairs, and maintenance. First, however, we will identify the customer’s wishes and needs, starting with the selection of materials and details. We perform waterproofing of roofs with PVC roll materials. We use mineral wool, polystyrene foam and PIR for insulation.
There is also a different choice of materials for the construction and repair of slopes.
During roofing works or as a special order, we install all the necessary sheet metal parts. The shape of the sheet metal parts depends on the specific character of the object and is prepared accordingly.
In addition, we install various accessories on the flat roof,
the main items being roof wells, negative pressure roof fans, penetrations, etc.
We carry out all work related to the flat roof construction process.

As roof coatings, we mainly use PVC, which has the advantage of good durability and the material has a manufacturer’s fixed warranty of 10 years. We give the works a guarantee of up to 5 years. PVC is an environmentally friendly material that is manufactured using natural substances: sea salt 57% and oil 43%. As a building material, PVC is affordable, durable and easy to use. The advantage of the material is its high durability – one layer of PVC coating is as strong as two layers of ordinary bitumen coating material. The material is installed with special hot air blowers, i.e., no open flame is used upon installation, which makes the installation safe.
For insulation, we mainly use expanded polystyrene (EPS), mineral wool (MW), light gravel (LWA) or PIR insulation. The advantage of EPS over mineral wool is better moisture resistance, but mineral wool, in turn, has good fire resistance (Fire Resistance Class A1).
The advantage of light gravel over other materials is considerable compression strength. However, the final selection is based on the specificity of the object and the customer’s wishes.
