Hammer a new nail into the roof about 1 inch above the hole from the previous nail.
Nails in my attic are dripping wet.
All of this is one half of your problem.
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.
Not sure if that has anything to do with it.
The best solution for controlling moisture is at its source.
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.
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.
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 moist attic means moist insulation and moist insulation is less effective.
I noticed that they installed 4 roof vents but did not cut them out.
The nails that you see in your attic get as cold as the outdoor temperature.
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.
A point often overlooked is that since it s winter the water freezes on the cold nails.
Could the roof have cooked itself in 8 years like that.
The nail chisel tips are rusted.
This is why you see the frost.
