How to do roof overhang for a solid roof?

I'm just wondering how to actually implement a certain roof overhang on a gable if you choose a solid roof. So we let the solid roof elements lie flush with the rising walls and end with them. On the eave side, I can still imagine it: The rafters lie directly on the solid roof and are bolted to it. Then mineral insulation can be laid between them, with the underlay membrane, battens and roofing on top. If you make the rafters a little longer, you get the desired roof overhang on the eaves side. But what about the gable? You can't just let the purlins protrude half a meter to hang an air rafter below. But with a solid roof, you probably won't be able to integrate purlins for the foot and ridge. Wherever vendors of solid roofing systems show pictures online, you won't see any details. Is it possible to attach a short false purlin on the outside to put an air rafter on top?

Does anyone have any ideas?

In this case, you are going to install purlins that do not carry any load other than to support the overhang, and put a spar on top.

Do you already have a solid roof or can you choose your own roof design?

Nothing is ready yet, first preliminary ideas are mature. Solid roofs seem to be built pretty rarely, but I see the advantages of that: you have a load-bearing, tight structure from the start, which is good, especially from a soundproofing standpoint, and you don't have to do any trim inside, just plaster. I like the roof trusses, but I like it to be completely quiet inside and no traffic noise, even during a storm.

In this case, I would look for a solution where the solid roof itself forms an overhang. Structurally, this shouldn't be a problem. The main advantage of solid roofs is that you don't have to do them on site. This simplifies construction coordination, reduces construction time, makes it less dependent on the weather, and saves the builder money. The quietness, the insulation, the finish – there are no fundamental differences.
