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