ᐅ Gable Roof or Flat Roof – Experiences?

Hello everyone,

let’s imagine you had the choice to build your house with either a pitched roof or a flat roof. Which would you choose? The flat roof is a bit more expensive but offers no sloping walls and makes it easy to have a rooftop terrace. The pitched roof is more affordable, but a rooftop terrace would be more challenging and there would be sloped walls everywhere.

The appearance is obviously quite different as well: I think a pitched roof looks more classic, conservative, and solid—while a flat roof appears more modern.

I’m looking forward to your arguments.

Best regards,

Flat roofs remind me of commercial buildings or multi-story apartment buildings.
A gable roof looks like a classic settler house but can also seem a bit old-fashioned. I like hipped roofs: at 25 degrees, it’s like a sports car; between 30 and 35 degrees, an SUV; steeper than that, it feels like a witch’s house.
Flat roofs don’t have an attic, which means less storage space for odds and ends. Roof terraces—what’s the point? They are either cold and windy or you’re roasting in direct sunlight.
Water, frost, snow, and UV exposure have so far damaged every flat roof I’ve seen, which gets expensive.

Then show some examples where it can’t be seen on the facade (it would probably have to be windowless).

Our facade could show a split level without the house actually being a split-level. And it has windows where this could be noticed.

You should not equate newly built flat roofs today with those from the last century. Just google "inverted roof." These are watertight due to the waterproof concrete alone, basically the same structure as a basement that is submerged in water. The additional waterproof membranes are placed above the concrete and below the XPS insulation, meaning they are protected from frost and UV exposure. In earlier constructions, there was wood with bitumen roofing felt on top, simply put, which deteriorated from weather exposure and, if it failed, directly exposed the wood to moisture.

Technically, that’s true. It’s similar to the term “prefab house,” where today’s reality hasn’t quite replaced the 1960s image in people’s minds yet.

Visually, there are still designers who aren’t quite “ready” for flat roofs. If someone can’t approach it aesthetically and simply sees a flat roof as a plain lid, then the house ends up looking like it’s covered by a concrete tarp. Without a more thoughtful approach to the building’s design and composition, it just becomes a simple box. Pitched roofs tend to be more forgiving on basic, generic houses—they might look “authentically traditional” at worst.

That's simply a matter of personal taste.

If you ask me how I would describe a typical house, today it would be a white rendered house with a gray gable roof.

Honestly, from a purely aesthetic point of view, I’m not really a fan of flat roofs, although I have seen some really stylish modern houses with them. I’ve also read that flat roofs are more expensive and particularly more prone to repairs.

Still, I have to say that practical benefits also matter. No sloping walls, plenty of window space, and the possibility of a continuous roof terrace. Even if the building permit / planning permission limits the ridge height, this can be a good solution.
