I ripped off my old roof and got it ready for laying the new shingles. I
planned on starting with a whole shingle, next course -4 inches, next
course -8. Then back to the full shingle.

With the 3/8 inch overhang required, each row of shingles is 24 feet and
7/8 inches. If I use full shingles, I come up 7/8 of an inch short at
the end of the row. Should I just allow a bit of space between each
shingle to make up the 7/8 of an inch over the 24 foot run or???

Why not just start the 1st course at -2 inches, then -6, then -10? It will
mean more cutting, but I don't think cutting one to 7/8 inch will hold to
the roof that well.

Of course, I'm not a roofer, and my advice is worth every penny you paid for
it
