Frost In Attic During Winter

If you have a roof leak in the winter months and it s not being caused by ice dam there may be another culprit.

Frost in attic during winter.

Frost accumulates in attics when moisture laden air from the house gets up there when it s cold. The air in the attic has water in it and it condenses on the cold metal. This will freeze if attic temperatures remain below freezing causing frost to build up. During winter there are usually three sources of humidity in an attic.

When the moisture gets into the attic it condenses on the roof. This exact same process is happening in your attic during extreme cold weather. The nails that you see in your attic get as cold as the outdoor temperature. A point often overlooked is that since it s winter the water freezes on the cold nails.

During winter conditions attic frost is a problem associated with attic bypasses. When the outside temperature rises again the frost thaws water collects and can leak into your house. This is why you see the frost.

That s about it pretty simple. You may pay an ice dam removal company to melt the ice dam off your roof only for the leaking to continue.
