Hello everyone!
We are currently planning a single-family house in North Rhine-Westphalia. The house was originally designed with a gable roof with a pitch of 47°. Additionally, there is a third gable with the same roof pitch. However, this gable seems a bit too small for us and should now be more of a classic Frisian gable. In other words, the ridge height should be higher and, consequently, the roof pitch steeper (the bay window beneath the gable should not be made wider).
How does the allowable roof pitch apply in this case?
The ridge height of the third gable should still be lower than the ridge height of the main roof. According to the development plan, a roof pitch of 38° to 48° is permitted for the main roof. The development plan does not specify further regulations, except for garages.
Does the roof of a third or fourth gable count as part of the main roof, or is it considered a subordinate roof and therefore exempt from the regulation in the development plan?
Perhaps someone can help us out.
Thanks a lot and best regards,

Does the roof of a third and fourth gable belong to the main roof, or is it considered a subordinate roof and therefore exempt from the regulations in the development plan? It depends on the perspective of an objective observer. If the roof structures no longer appear subordinate from the viewpoint of an imagined knowledgeable observer but rather as independent components, they are subject to the same restrictions as the main structure. This usually applies to cross gables. With dormers, the boundaries are more fluid and often lead to disagreements between the homeowner/architect and the permitting authority.
Does the development plan actually refer only to the "main roof"? Could you quote the exact wording?

Call the district building authority, make an appointment, go there, explain the situation—I expect they will approve it. Alternatively, raise the dormer walls and use a shallower pitched gable roof. However, I don't think that will be necessary. Have a talk with them. Karsten

We have the gable roof now, but we don’t like it.
I have an appointment with the architect on Monday. He’ll know.
I just wanted to do some preliminary research myself. Uncle Google didn’t really turn up much.

So, the ridge height is supposed to increase and consequently the roof pitch steeper (the bay window under which the gable is located should not become wider). [...] The ridge height of the third gable should still be lower than the ridge height of the main roof. Steeper pitch but not higher ridge: the base not being wider is basically already given. Where the additional space would come from is unclear to me. There is only limited room to adjust the pitch (half the house depth minus the width of the dormer). What pitch increase are we talking about here?
A ridge height of the captain’s gable higher than the main roof’s ridge height would also look odd.

We have the captain’s gable now. But we don’t like it. Then why insist on a captain’s gable – that seems illogical to me. More space would rather be gained if the third gable were flatter, by adding a knee wall inside the gable. However, with such a steep main roof, that is also not visually appealing.

He is talking about the roof pitch of the main building. So not about the “main roof.” That is a different matter and relates more to the garage, which could then have a shallower roof pitch.
