How far should shingles overhang drip edge?

Should shingles extend past drip edge?
The edge of the shingles should hang over a roof between an inch and an inch and a half — or between a half inch and three-quarters of an inch if drip edge flashing is installed. Too much overhang and the shingles could blow off in high winds; too little can allow water to seep into rake or fascia boards.
What nails do you use for drip edge?
The drip edge is nailed in place using 1-1/2 galvanized roofing nails. A felt-tip marker works great for marking cuts. And, again, prying open the end with a small flat bar allows the pieces to overlap cleanly.
Is drip edge required by code?

Do I need drip edge on shed?
Your shed should be built to withstand the elements. That means repelling water in the most efficient way possible. Installing drip edge around the perimeter of the shed is the best way to keep water out and away from your shed.
How do you extend a shingles overhang?
To fix an overhang that’s too short, buy some aluminum drip edge (aka drip-cap flashing). It’s typically sold in 8-ft. lengths, and can be cut with tin snips or even poultry shears. Slide the wide, flat flange of the flashing under the first course of shingles and adjust it to extend over the gutter.
Should gutters be flush with fascia?
In most homes, the gutter is flush with the fascia. … This allows rain water to drip off of the shingles and onto the gutter apron, then directly into the gutter. Gutter apron is also needed for rubber roofs, but in that case, the rubber from the roof can simply be set to hang down into the gutter.
Does roof sheathing go over fascia?
When sheathing a roof, the first step is to snap a line so that the first row goes on straight. But if you snap it at 40 inches, then the sheathing will not project over the subfascia or true fascia. This opens the door to the possibility of water damage by letting gravity work against you.
