Material facade & roof

Hello everyone,

I have a question for the knowledgeable among you. We are currently in the planning phase of our house, working with an architect. We are building a 1.5-story gable roof house using solid wood construction. Our wish was for the facade material and the roof material to be the same. Originally, we planned to use standing seam metal roofing for the roof and angled seam metal panels for the facade, but I keep coming across houses in my literature like these here, whose roofs continue the wooden cladding of the facade - which I personally find much nicer:

All roofers and other practitioners, especially fans of traditional solid construction, immediately throw their hands up in horror - "Wood on the roof? Never!! The moisture!!!" But what I wonder is: why then are there so many houses where you still see it? Or put differently: what do they do to make it work? I don’t believe the architects of these houses did it out of naivety or ignorance. Interestingly, these types of roofs are also uncommon only in Germany - in the Anglo-American area, in Scandinavia, but also in Austria and Switzerland you find this much more often. One might argue with the weather since in Austria and Switzerland they probably have different precipitation than here. But in Norway? Sweden? Denmark? Or even... England??? :D
So, I would really be interested to hear what you say about it.

PS: I’m less interested in the advantages of roof tiles or standing seam metal roofing now, as I am quite aware of those! ;)

Take a look at the houses in real life. Sure, it only works in Russia. There must be a reason for that ;-) What is underneath the wood-look roof, can you say? Talk to the architects of the wooden roof houses - find some in the countries you mentioned.

...that would definitely be a great justification for an exciting vacation. But the idea of contacting the respective architects directly is good, I will try that. I am particularly interested in what is under the wood - maybe bitumen sheets? Interestingly, my books always say a lot about wall construction, heating, etc., but the roofs are conveniently left out - presumably no one wants to get into trouble.

Just ask your architect why he does not want to fulfill this wish for you in Germany. Or try to solve points such as roof drainage at the eaves without a gutter. Or think about a point like "hard roofing" in inner-city situations, where fire protection requirements play a role. Or about durability, reparability. Outside the scope of German building laws and standards, such experiments may be easier to carry out. Here they are not approved by the building authority or require a private agreement between builder and architect, whereby the risk for the deviation ultimately always lies with the architect. Such claddings have the actual roof, which must meet all technical requirements, invisibly underneath as a prerequisite. So, two roofs are built. The avant-garde maximum demand of design also includes the ability to manage all consequences for implementation and, for example, to finance them. But maybe you will succeed in solving the constructive details perfectly and thus convince your architect.

...that's a good point - so that the roof corresponding to the requirements is beneath the cladding. I have read about a roof clad with wood, under which bitumen sheets were laid. The architect has not yet said that he does not want to fulfill the request; he just had other ideas so far :)
