backwards shingles
My neighbor installed his shingles on his porch roof with the tabs up so that the 3 tabs are covered by each next course. He insists that this is the way he has always done it. Im not a builder by trade but is this possible?

Anything's possible...but that doesn't mean it's correct.
Actually, it should still shed water, but if I'm understanding you correctly, it is not correct.
The thing I would be concerned with is the appearance.
Manufacturers always use the proper granules on the tab portion of the shingle (the face), but they often use any granule that they have available for the top portion that goes under the course above. (Since is doesn't show)
I can't imagine that he would have the same color all over his roof if he put them on upside down.
