Nails are faliing from my roof.
There s really no fix other than replacing the damaged vents.

Drive 1 2 more nails into the fascia board at each of the rafters.
Usually the cause is the nail falling in a crack such as sheathing joints or probably in your case cracks between the rake trim and roof if you have old t locks that were face nailed to hold the ends down they always work out it would be easy to peel a shingle back on the edge to see if this is the problem.

If the roofing nail happens to penetrate the sheathing along this seam there is very little solid wood to hold the nail.
If this happens there is virtually nothing holding onto the nail.
Also look for pulled or missing nails at the base s bottom edge.
There will be nails across the top of the vent too.
A large nail head and heavier shank gauge provide greater holding power.
In most cases you can remove nails under the shingles on both sides of the vent to pull it free.
