The problem is probably not that the floor 'jumps in front of' the
roof, it is more likely that the roof is positioned in front of the
near clipping plane and is not being rendered.
If you do a ResetCameraClippingPlanes before each render the problem
should go away (as long as roof does not end up behind the camera).
