Renew garage roof independently

Provided that the garage is used solely for vehicles and not as a living space, I would cost-optimally install a trapezoidal sheet on the rafters and omit the cladding at the bottom. The rafters certainly look OK for a garage as well. No additional battens, everything kept very simple. Costs around €10 per sqm.

maybe spend a few extra euros on trapezoidal sheet metal with fleece laminated underneath -> dampen rain noise and avoid condensation on the underside (due to corrosion)

The garage is used for one vehicle and storage space, basically what you usually keep in a garage.

The trapezoidal roof would need to have fleece to prevent condensation from forming, because we really don't want that.
I would add cladding at the bottom, if only for aesthetic reasons. It should look somewhat decent.
The only thing left then is the color difference compared to the house roof, which might bother some people.
I can't recall the name right now, but at the front and possibly on the side of the garage, you'd also need some kind of finishing to make it look neat.

You don't have that with the Eternit panels either.

Trapezoidal sheet metal is available in several colors.

You can also use sandwich panels, about €30 per sqm and also available in various colors. I would not want to use Eternit.

Yes, in front of the garage there is a shed roof end. On the side there is currently nothing, correct. So there has to be a shed roof end again at the front; on the side we are still considering. For Eternit there would be corrugated gable angles here. Of course, we would also take red, like the house roof, but whether it is the same red would have to be checked.
