Yep that is what I thought. In the gauntlet perspective trick, you choose one degree of enclination and you align that with the camera so that surfaces on that angle become a line. However, that only works with that single angle of slope, so if you do that for the top roof (more sloped), the lower roof which is less sloped should have its back slope visible, even if very squished.
Alternatively you could decide that the angle that aligns is the one of the lower roof, but then the whole building would be seen from a lower perspective, and the lower roof would cover less of the door and the front wall, while the top roof would extend beyond the back limit of the lower roof.
Or you can ignore my geometry nitpicking altogether and slam it as an intentional cheating like so many games do lol.
Also, I don't quite like what you did where the top of the pillars support the roof, shouldn't those corners be symmetrical? I don't think they look very much like real wooden architecture.
That said, I liked how you actually applied perspective by covering a lot the wall and door with the lower roof, people tend to make very wrongly frontal looking houses on top down, and your stand out like being much more correct.
