Hi. At attached picture, the lowest roof is supposed to end near to the wall, but it seems like the roof calculation for that roof follows the upper roof - why? OK - I cannot upload picture, but maybe you understand my question anyway.
Roof calculation.

Without picture or position it is dificult to find the reason. Perhaps it is the intersection between the two roofs. You have to know that the building outline of the roofs too are involved in the intersection.

But the 2 roofs do not touch each other - at least not in the height. But the one roof goes under another roof. So when the outlines are seen from above, then yes, they cross each other.

Please give us the position.
