Can someone educate me about this unusual roof?

I think there is a chance the roof ridge isn't parallel with the sq of the home, and its causing a distortion.... the roof overhang is so large it doesn't show as obvious. Maybe its both a distortion and flare - unless the photo is distorted and that's the problem (but then I shouldn't be able to get clear vanishing lines on the windows).

***ADDED
As I am sure you know, we should be able to get vanishing points with the lines of the home - like in this picture I did the same thing with.
