  • In addition there are the costs for the thermal insulation, which again costs between 30 and 60 EUR per square meter of roof area. Efficient insulation according to the latest standards requires a higher initial investment - and saves the most energy costs.
  • When choosing the roof covering, you can turn the price screw the most: with costs of 20 to 100 EUR per square meter, this cost factor has the largest margin. The actual price is mainly determined by the material you have selected.

Costs for the new flat roof
