Frost Buildup In Attic

Without proper attic ventilation in your home you could have a considerable amount of frost accumulate in your attic during the cold winter months.

Frost buildup in attic.

House pressure affects. When moisture gets into the attic it condenses on the roof sheathing in the form of frost. More indoor humidity more frost in the attic. When the outside temperature rises again the frost thaws water collects and can leak into your house.

How to prevent frost in the attic frost comes from air leaks. That s about it pretty simple. When the weather warms up the frost will become water droplets and evaporate harmlessly. High humidity in homes first of all if the relative humidity of air in your home is too high work to lower it.

On dec 17 2010. This frost is the result of warm air rising from the living areas underneath. To start frost accumulates when moisture laden air from the house gets into the attic. When warm air from inside the house escapes traveling up through the bypasses the moisture condenses on the roof boards and rafters where the frost can form.

I ve blogged about attic air. Frost gets into the attic from air leaks or attic bypasses. During winter conditions attic frost is a problem associated with attic bypasses. The more humid a house is the more frost you ll find in the attic.

This post is largely a re blog of my last post on attic frost but that was from 2013 and it s time for a reminder about all of this. It is a serious problem because the frost turns into water as it dries out and this water will then leak into the home rot out the roof and joists and cause mold to grow.
