Drip Edge

My roof is asphalt 3 tab shingles, and the shingles extend past the fascia and over the gutter. The drip edge is not the typical T shape and is a simple L shape that drops down flush against the fascia board with a little kick-out at the bottom edge. Is this OK?

Thats actually the most common type of drip edge I've seen. If installed correctly (as well as the rest of the roof) it shouldn't be an issue. It's what I had back in VA and it was fine.

I used the T type when I did my neighbors carport...but it's roll roofing with a very slight slope. I just wanted a bit more support at the edge...plus it was the only one available with the larger leg that attached to the roof.

The L-shaped flashing you have is called "gutter apron" and is the correct flashing to use above a gutter, since it has a long downward bend to flash the top of the gutter, but it is not really an "L" since it is bent at roughly a 20 angle to account for some of the roof pitch. The other common kind of drip edge is called 5" d-style, and it is usually used on the rake or gable end of the house. The downward bend on 5" d-style is not sufficient to cover the back edge of a gutter since the gutter will usually drop below it's 1" downward bend. 6" d-style has a longer downward bend and would probably be okay to use over a gutter.

In some parts of the country "gutter apron" isn't commonly used. I guess those people must be used to having their gutters leak.

Your shingles should never extend more than 1" past the edge of your flashing. IMO 1/2" is plenty. I like to let the starter hang over 1/4" and the shingles another 1/4". But if the roof edge is really crooked sometimes you have to let it hang over more to get a straight line.
