I recently had my siding replaced, which included all fascia, flashing, etc, and new gutters.
I notice that the drip edge is no longer securely against the gutters or fascia. In some cases, it seems to be pushing against the gutter parts and raising the shingles.
Should I get some white finishing nails, and go around nailing the drip to the gutters/fascia?
No, don't add nails. They'll create leaks and make the issue worse from a visual standpoint. You'll have obvious dimples in the metal. With thermal expansion you may see moderate to severe buckling.
Just go up and flex the drip edge back into an acute angle. This will put tension in it and it'll stay tight to the fascia. Just lift it a bit and squeeze gently. Don't overdo this or you'll create "ski jumps", which can cause water backup.
In the cases where a gutter bracket is holding things up, use a snips to make a short vertical cut on each side of the bracket and bend that tab out slightly. Or lower the bracket (while maintaining adequate slope).
The key word is recent. What you have shown to be concerned with are issues with this job and they should be corrected. Some things like the wavy drip edge is primarily an esthetic issue, but still speaks to the quality of work. The gutter anchor pushing up shingles is shameful and has to be corrected.
If the job was done 30 days or less definitely call the contractor back. If longer, look at you documents and see if you have a warranty on the work.
