Good day!
I’m wondering how to create a certain roof overhang on the gable side when choosing a solid (or monolithic) roof. Let’s say the solid roof elements rest flush with the supporting walls, ending evenly with them. On the eaves side, I can understand it: the rafters rest directly on the solid roof and are screwed in place. Between them, you can place mineral insulation, followed by the underlay membrane, then battens and finally the roof covering. If the rafters are made a bit longer, you get the desired roof overhang on the eaves side. But what about the gable side? You can’t simply extend the battens by half a meter (about 20 inches) and then attach a ventilation rafter underneath. It seems that with a solid roof, there’s no option to integrate wall plates and ridge beams. Everywhere I’ve seen photos from solid roof system providers online, there are no details about this. Would you attach short, fake wall plates on the outside to support a ventilation rafter there?
Does anyone have an idea?

Nothing is in place yet, the first tentative ideas are taking shape. Well, then you actually screw on some short fake purlins... Solid roofs seem to be built rather rarely, but I do see some advantages: You have a load-bearing, airtight structure from the start, which is especially good in terms of sound insulation, and from the inside no additional finishing work is needed, only plaster needs to be applied.
I generally like traditional timber roof frames, but I find it great when it is completely quiet inside and no movement noises can be heard during storms. If you are planning a very simple roof structure without dormers anyway, this could be interesting. But as I said: My ideas are just at the beginning, and I am actually well taken care of in terms of the house...

The main advantage of solid roofs is that they do not need to be constructed on site. This simplifies construction coordination, shortens the build time, makes the process less dependent on weather, and reduces costs for the builder. Soundproofing, insulation, and finish—there are no fundamental differences inherent to the construction method.
When the time comes, present your requirement for a “quiet, calm house” to your architect. You can explain this, for example, by referencing your lifestyle or your profession as a musician. This will help the architect understand your needs better and consider this aspect in other areas of the design—provided they are a good architect.

Rare is not quite right. They are just as unusual as a Canadian log cabin made of solid wood logs in the middle of Berlin.
Why? There is no real reason to choose a solid roof. Also, it is more expensive.

Even though I don’t yet know when I will start building my next house, one thing is certain: there will be no architect involved. At most, there might be one who just puts their stamp on the drawings and provides some occasional advice. That’s exactly how we did it 20 years ago. No architect will think through a project as deeply as you do yourself. Back then, I only drew things I was confident I could actually build. And at that time, there weren’t even online forums to ask questions…
For me, it’s not at all unreasonable to also build the roof using factory-made solid brick elements, especially since the rest of the house consists of Liapor solid wall elements. I would definitely do that again because I am convinced of this approach. It saves a lot of detailed work in the interior finishing of the attic, where you have to be extremely careful about airtightness. I’m also not a fan of spending weeks cutting, screwing, filling, and sanding drywall panels. Right now, even wearing masks annoys me because my glasses fog up.
When I have several options to choose from, I generally go for the one with fewer short- and long-term uncertainties. That’s why I see the solid brick roof as an advantage, but I’m happy to be convinced otherwise. In that case, I’d simply add a few short fake purlins in front. I wouldn’t let the elements themselves extend beyond the roofline, as this would lead to an extremely thick roof assembly (solid element plus rafters plus battens plus roofing, which quickly adds up to about half a meter (20 inches)), and that doesn’t look good.
