Quote from the Energy Saving Ordinance §10 (3): "Owners of residential buildings as well as non-residential buildings, which are heated for at least four months per year to indoor temperatures of at least 19 degrees Celsius (66°F), must ensure that accessible ceilings of heated rooms to unheated attic spaces (top floor ceilings) that do not meet the minimum thermal insulation requirements according to DIN 4108-2: 2013-02, are insulated after December 31, 2015, so that the thermal transmittance (U-value) of the top floor ceiling does not exceed 0.24 watts/(m²K). The requirement is considered fulfilled if, instead of insulating the top floor ceiling, the roof above is insulated accordingly or meets the minimum thermal insulation requirements according to DIN 4108-2: 2013-02. For insulation measures in ceiling or rafter cavities according to sentences 1 and 2, Annex 3, item 4, sentences 4 and 6 shall apply accordingly."
How can I now find out if the roof needs to be redone or not? Is there any way to measure this? Technically, it is fine, as it has been regularly maintained and "patched."
Also, the last paragraph of §10 is interesting, namely (5):
"Paragraphs 2 to 3 do not apply insofar as the costs required for the retrofit cannot be recovered within a reasonable period through the resulting savings."
Who decides whether the roof insulation is cost-effective or not? What is considered a reasonable period?
Who is the authority responsible for inspecting and answering all these questions?
Thank you very much!

As far as I understand from the paragraph you quoted, a flat roof generally does not have an unheated attic space or a roof above the top floor ceiling, so this section does not apply to a typical flat roof.
I don’t have expertise in this area – I just read the paragraph carefully with my own understanding.
Maybe this helps you?!
