Hammer a new nail into the roof about 1 inch above the hole from the previous nail.
Nails in my attic are dripping wet.
This is why you see the frost.
All of this is one half of your problem.
In your case a attic access hatch or doorway is leaking badly allowing quantities of water laden air to come in contact with your roofing nails.
I have a roof that is 10 years old gaf timberline 25.
If the women don t find you handsome they should at least find you handy.
If the problem is the result of water or moisture penetrating the foundation or floor slab there are many remedial actions which may help.
The nails that you see in your attic get as cold as the outdoor temperature.
The best solution for controlling moisture is at its source.
The nail chisel tips are rusted.
There may be no vapor barrier in your ceilings allowing the water vapor to pass into the attic.
A point often overlooked is that since it s winter the water freezes on the cold nails.
Every nail chisel tip in the attic is dripping.
Could the roof have cooked itself in 8 years like that.
Not sure if that has anything to do with it.
Not sure there is much you can do about it other than maybe spray the tips of the nails with some rubber coating to insulate it from direct cold wet air contact.
Also my wife had the roof done before we married.
Excessive attic moisture condenses on the cool metal surface of the roofing nails causing corrosion or rust on the nails and stains on the surrounding wood materials.
I noticed that they installed 4 roof vents but did not cut them out.
The air in the attic has water in it and it condenses on the cold metal.
