Condensation in attic spaces can be alarming depending on how much you re seeing. This condensation can form droplets of water and accumulate into the insulation below.

Condensation in an attic will form first on nails that penetrate the sheathing and thus check them for evidence of corrosion. Frost on nails is frozen condensation. 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. To prevent frost condensation from developing in your attic you must eliminate or reduce the amount of air leakage into the attic as well as improve insulation ventilation to allow moist air to.
