If you do the job right, using ice and water shield for the first, I forget the number, but it's like somewhere between 24 and 36" from the inside wall, the drip edge would not cause a problem at all since the ice and water shield attaches to the drip edge. It's adhesive backed.
There is also three methods to do the first course. 1) invoves cutting the shingles, 2) involves a double layer of shinges (less wind resistance) and 3) involves using a starter strip. The starter strip has a layer of adhesive on it. When you cut and invert it, the shingles, you make sure the adhesive strip is present.
I don't like it. I'm pretty sure using the ice and water shield you won't have a problem. Some shingle installations will not be warrentied without the ice and water shield.
