Every nail chisel tip in the attic is dripping.
Nails in my attic are dripping wet.
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.
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.
The air in the attic has water in it and it condenses on the cold metal.
A moist attic means moist insulation and moist insulation is less effective.
The nails that you see in your attic get as cold as the outdoor temperature.
If the problem is the result of water or moisture penetrating the foundation or floor slab there are many remedial actions which may help.
I have a roof that is 10 years old gaf timberline 25.
The best solution for controlling moisture is at its source.
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.
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.
Could the roof have cooked itself in 8 years like that.
The nail chisel tips are rusted.
I noticed that they installed 4 roof vents but did not cut them out.
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.
If the women don t find you handsome they should at least find you handy.
There may be no vapor barrier in your ceilings allowing the water vapor to pass into the attic.
This is why you see the frost.
Also my wife had the roof done before we married.
