I noticed the other day while replacing some shingles that the aluminum covering my fascia board was bent a bit. I think part of the problem was I sparingly used the soffit nails to attach it, and kept them high to avoid any possible drips. It looks to me if I just added a nail lower where it bent out everything should be fine. This led me to a few minute details on fascia nailing which I thought I'd ask.
1) Should the nails be kind of loose to let the fascia float a bit? My understanding on siding was that you don't want to nail it down too tight, is fascia done the same? I'm wondering if a bit of the bend was from nailing it too tight
2) Should I keep the nails high when nailing it? If they are lower, should I be going back over with a good exterior caulk it?
