Sagging sheathing over decent shingles
I am buying a house in PA (near philadelphia) that was built with 3/8" sheathing on 16" centers. The sheathing is generally sagging a little all over but in one place it is very weak. It is a colonial style home with an upper and lower roof. The shingles are only about 8 years old. There are no current or previous apparent leaks.
Questions:
1. Can I tear off the shingles and put 1/2" sheathing on top of the existing sheathing? I would obviously do this to the whole roof not just the really bad place.
2. Would OSB be appropriate for this job?
3. Are there any things that I need to think about as a result of having increased the thickness of the roof surface? (flashing, drip edge, etc.)
Thanks in advance for your comments.

Like said call and check code for where you are.
If you do add on you could just add on a new fascia board over the old one and come up higher to match the new roof edge. Then the standard metal drip edge should work.
