Flat roof or pitched roof: what costs are to be expected?

Of course, the question "What does a new roof cost?" Can not be answered on a flat-rate basis, but we can give you some pointers to the price assessment. For this we roughly divide the roofs into "flat roof" and "pitched roof".

Cost of the new pitched roof

  • The size of the roof is always crucial for the price. For a pitched roof, you should expect a cost of an average of 60 EUR per square meter for the roof truss in the shell.
  • 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 a 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.

Cost of the new flat roof
