Saddle or flat roof - experiences?

Flat roof, to me it looks like a commercial building. Or like multi-story residential construction. Gable roof, looks like a classic settler's house. But also somewhat tacky. Hipped roof, I like it when it's 25 degrees, then it’s Ferrari, from 30-35 SUV, above that witch’s house. The flat roof has no attic, that steals storage space for odds and ends. Roof terrace, what’s the point. Cold and windy, or you roast in the blazing sun. Water, frost, snow, and UV have so far made every flat roof brittle, and then it gets expensive.

Then show some examples where you cannot see it on the facade (it would probably have to be windowless).

Our facade could show a split level without the house being an SL. And it has windows through which you could notice this.

You must not equate newly built flat roofs today with those from the last millennium. Just google inverted roof. It is already waterproof due to WU concrete, basically the same construction as a basement that is standing in water. The additional waterproof membranes are located above the concrete and below the XPS insulation, meaning there is neither frost nor UV radiation affecting the membranes. In the past, you had wood and bitumen felt on top of it, simply put, which suffers from weathering and, if it fails, directly exposes the wood to moisture.

You are not allowed to equate newly built flat roofs today with those from the last millennium.

Technically, indeed not. It is similar with the "flat roof" as with the "prefabricated house" in that today's reality has not yet fully replaced the image from 1960 in people’s minds. Visually, it is such that there are still planners who are not "mature" enough for flat roofs, unfortunately. If one cannot handle it aesthetically and simply sees the flat roof as a flat lid, then the house looks as if it were covered under a concrete tarpaulin. Without a more conscious sub-building-mass arrangement, one then creates a mere box. The gabled roof is more forgiving in the overall effect on cookie-cutter houses; at worst, they then look "authentically plain."

That is simply a matter of taste.

If you ask me how I would describe a 0815 house, it would today be a white plastered house with a grey gable roof.

To be honest, purely from an aesthetic point of view, I'm not really into flat roofs either, although I have seen some really stylish modernist houses. And I have also read that flat roofs are more expensive and especially more prone to repairs.

Nevertheless, I have to say that practical usefulness also matters. No slopes, lots of window surfaces, continuous roof terrace possible. Even if the development plan specifies a low ridge height, this can be a solution.
