Nails from attic is normal.

The best solution for controlling moisture is at its source. If the problem is the result of water or moisture penetrating the foundation or floor slab there are many remedial actions which may help. This exact same process is happening in your attic during extreme cold weather. This is why you see the frost.

You need much more ventilation in. 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. 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.

A moist attic means moist insulation and moist insulation is less effective. When nail pops show up on the ceiling of the floor just beneath the attic and near a wall intersection the culprit is a phenomenon known as truss uplift or a variation of it. The air in the attic has water in it and it condenses on the cold metal. You see this same thing happen in summer months when you place a glass of cold water or a can of cold soda or beer on an outdoor table.

Nails first because they readily conduct cold. As you age you may develop vertical ridges or your nails may be a bit more brittle. When you see water and ice on the nails the actual temperature of the nails is at or below the dew point of the air in the attic that is saturated with water vapor. The nails sticking through the roof sheathing is normal.

The condensation is caused by warm air leaking through the insulation between the top floor and the attic. Nail abnormalities can result from injuries. Nail pops are largely due to wood or drywall movement and often appear within a year of construction.
