How to handle melting frost in the attic?

Winters are cold in Iowa with temperature as low as 14 °F (−10 °C) in January in the northwestern section and even lower (about −6 °C) in the southeast region. Snowfall is light as compared to the other states.
When winter’s end, all the frost in the attic starts to melt and results in water damage.

Signs of water damage

1. Dark or Wet Spots- Discoloration on the ceiling and the interior and exterior walls of your home.
2. Cracking, bubbling or flaking paint on ceiling or sidewalls.
3. Pooling of water below places of leaks or drips.
4. Sounds like dripping water, creaking floors also indicate melting frost in the attic.
5. A sudden increase in electricity bills.
6. Damp, musty, or moldy smell.

Frost and ice forms in attics when warm, humid air accumulates and condenses on the underside of your roof sheathing. Depending on the climatic conditions and temperature, and the state of insulation in the attic, one can experience frost in the attic. A little bit of frost forming is not alarming in really cold weather as it can melt and evaporate and wood can dry out soon.
But, it can become a bigger problem if the quantity of frost is large and is not able to evaporate completely.

Frost in attic and how to fix-

Statistically, ice or frost in attic forms in the attic after DIY roof insulation projects where new insulation covers up ventilation access.

Checklist for frost in attic-
1. Check the humidity levels of your home – do you have high humidity and condensation problems?
2. Is your attic properly ventilated?
3. Check for air leakage from the ceiling.

High humidity in your home-

50% Relative Humidity is too much. Bring it down to 35-40% or so. More humidity means more condensation.
Humidity levels can be decreased by simple tips and tricks like using bathroom and kitchen fans while showering and cooking, installing a dehumidifier in the basement and avoiding hanging wet clothes to dry inside the house.

Attic ventilation:

Keeping your attics properly and sufficiently ventilated can prevent ice in the attic and prevent frost on underside of roof sheathing.
Check that insulation isn’t jammed down on the edges and blocking soffit vents. A proper unobstructed air flow keeps roofs and attics dry.

Ceiling air barriers:

Keep a check on the air leakage if you have ice forming in the attic. Old electrical fixtures are prone to leaks and it is best advised to replace them with latest LED fittings which are not only carefully sealed against air leakage but also use less energy.
Air barriers are put by lifting insulation, laying down a polyethylene vapor barrier over the whole surface and then reinstalling the insulation.
Hence, it is best to get it done by qualified and trained insulation contractors.
