Also my wife had the roof done before we married.
Nails in my attic are dripping wet.
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.
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.
The air in the attic has water in it and it condenses on the cold metal.
The nail chisel tips are rusted.
These same condensation points the roofing nails will often map exactly the drip stains found on the attic insulation or attic floor below each nail.
Hammer a new nail into the roof about 1 inch above the hole from the previous nail.
A point often overlooked is that since it s winter the water freezes on the cold nails.
The nails that you see in your attic get as cold as the outdoor temperature.
Not sure if that has anything to do with it.
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.
Could the roof have cooked itself in 8 years like that.
All of this is one half of your problem.
If the women don t find you handsome they should at least find you handy.
This is why you see the frost.
There may be no vapor barrier in your ceilings allowing the water vapor to pass into the attic.
Every nail chisel tip in the attic is dripping.
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 best solution for controlling moisture is at its source.
If you have a friend in the attic ask him to direct you to a sturdy spot where the nail can bite into the wood.
