Yesterday with air temp of 9 degrees F and 15-25 mph breeze, my worn
out 64-year-old ass tried to replace the shingles that were torn off.

brrr...

had to simply nail shingles and so the roofing nail heads are exposed.
About an inch of snow overnight wth freezing rain later, and then an
1" of regular rain tomorrow.

Yeah, it's a no-no to have roofing nail heads exposed but is there
some type of adhesive that can be used this time of year to cover up
nail heads, or must I wait until a 50 degree F day comes along?

I'd leave it for now, then when it's above freezing (and any ice has melted
off the roof), if still pending the work, I'd go up there with some sort of
silicone and just touch cover the nails all around. They wont hurt anything
for a short time as they are. If it's going to be a month or 2, I'd want to
cover them as temp thing.
