some roof shapes not rendered with exact heights

[Sinuhe20]

Some roof shapes seem not to be rendered with exact heights given, see for example the roof on the Westwerk of the Aachener Dom:

A pyramidal or dome roof only works if roof height is slightly reduced to e.g. 24.9 m.

But a gabled roof works here with the full height.

The other building parts with domed or pyramidal roofs seem not to have this problem.
