3D Print of 11 Turpentine Alley

It all looks great, but I'm not sure I can print it without support, the Roof Middle.stl piece got this huge part, parallel to the plate it's like 2 inch by 2,5 inch and it's floating an inch from the plate.

I got my FDM printer yesterday, maybe there is something I dont know?

The pic is from the piece in question seen from the bottom.
