The issue could be the Intersection Priority (IP) of the Building Material (BM). It looks like the Wall IP is greater than the Roof, so the Roof is getting cut before the SEO is evaluated.

Yes for automatic trimming (Priority Based Connections), the strongest Building material will dominate.

Otherwise you have to resort to manual trimming which can sometimes be tricky as walls will automatically try to connect reference lines, unless you specifically cut/split them where you want and delete the bits no longer needed.

Or, if you do not want to modify the Intersection Priorities of Building Materials, you can also select the Wall the End Surface is showing on the surface of the other Walls, and check the "End Surfaces: Override using Adjoining Walls" checkbox.
On the following image, on the left, the thicker Wall has this checkbox checked, on the right, it does not.
