Flat roof with approx. 80cm parapet, then mounting on supports is not an issue and also not visible from the street. Definitely better than 35 degrees mounted on the garage, visible to everyone.
The attractiveness of the property) is influenced less by the type of heating and hot water system than by the type of radiators. That means if you say "gas heating," I find that modern. If you said "radiators," I would counter that (completely or predominantly) underfloor heating is now considered standard,
It always depends. Personally, I find underfloor heating (slow to react) the worst thing you can install in children's rooms or bedrooms. That's why we love our "radiators"

We currently have underfloor heating and find it so sluggish. It takes ages to adjust the temperature accordingly. Especially in weeks with high outdoor temperature fluctuations, it is quite uncomfortable. The underfloor heating is always lagging behind.
Gable roofs are currently almost the more exclusive variant again (in the sense of "you don’t already see eighteen of them on this street").
We also like gable roofs much better. But unfortunately they cannot be approved due to the height and because we definitely want two full floors.

From my point of view, this is not a fundamental disadvantage but the result of a common planning error.

Gable roofs do not differ in pitch from hip roofs, but by a ridge running continuously to straight gable ends on both sides, whereas the hip roof – practically without gable ends – only has sloped roof sides. The range of possible pitches is basically the same for both.
