does not break, only changes color.
...So this is no longer an issue. 😉

The roof looks very good!
I'm no professional, but I have a few comments.
Different wood species are classified into various durability classes and, under the same conditions, have different life expectancies. Depending on the construction and weather conditions, it’s hard to predict how long a roof will last. If the structural wood protection is not properly implemented, even the hardest and most durable wood won’t help. The structure will start to rot faster than you can imagine.
The most important thing for outdoor wooden structures is that they are not exposed to constant moisture. Ideally, they should have no ground contact (which you don’t have). The contact surfaces between the wood pieces should be as small as possible to avoid water retention. You should observe if water accumulates anywhere and doesn’t dry quickly. Those will be the areas that start to rot first.
Was end-grain protection applied after cutting during the construction? If not, those parts of the wood can absorb moisture faster and develop cracks.
I would say that coatings increase the lifespan of the wood. However, this involves effort, and whether it’s worth it depends on personal decision. 🙂
With my wooden terrace, I tried to follow all these points as closely as possible and plan to regularly oil and maintain it. Let’s see how long it lasts. A wooden terrace can hardly be compared to a wooden roof, though.
What I did notice positively after oiling is that water drains much better and does not partly penetrate the wood anymore. (What a surprise 😀)

So this is settled. 😉 (5th word)Could you please share the dimensions with me, maybe also the height? Is this the south-facing side? Just to get a better idea for our project. And... how is / will the roof above the boards be constructed?
The roof is 6.00 m (19.7 ft) wide and 4.40 m (14.4 ft) deep.
The niche is 0.85 m (2.8 ft) wide and 1.60 m (5.2 ft) deep.
The heights can be found in the picture.
A 25 mm (1 inch) thick three-layer panel rests on the beams.
On top of this will be the waterproofing and green roofing.
For the slope, the beams were already milled at the factory to direct the incline towards the outlet.
At the outlet, there will be an external gutter box, from which a downpipe leads down to the granite wall with free drainage.
