Boxing in overhang
Welcome to the forum! Sorry to hear the nails are poking through on the overhang. Asphalt 3-tab manufacturer's used to let you use shorter nails on the overhangs and still warranty their product. The code is min. 3/4" into sheathing or through if sheathing is <3/4".
And most inspectors will accept short nails there only for looks. You cannot clip them flush and paint, even if galvanized. If you go closed soffits, plan ahead on the gable ends for the returns and how they will look. Install continuous screened vents for air supply right next to the fascia board so not to get wind driven snow and rain into attic space. Drill each bay blocks with 3- 2" holes. Add continuous ridge venting with baffles if not there already.
Be safe, Gary
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
