Ice Condensation In Attic

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

Ice condensation in attic.

Mold mildew or rot can occur. Frost and ice forms in attics when warm humid air accumulates and condenses on the underside of your roof sheathing. Exhaust them with turbine vents. Recognize the signs of stress when too much snow and ice has accumulated on your roof or when you have too much condensation in your attic.

A silent cause of winter roof leaks. Ice dams form when heat leaking into attics or roof cavities from the building below or from attic ductwork melts the bottom layer of snow on the roof. The warm moist air trapped inside of your home is coming into contact with the cold wooden surfaces in your attic forming large damaging water droplets. The same thing may be happening on the inside of your attic.

The conditions that cause ice dams often cause attic condensation too. Sagging ridgeline drooping ceilings water leaks on interior walls and ceilings jammed doors cracked interior walls near the center of your home creaking sounds. Moisture accumulation is most significant when outside temperatures are very cold because air holds less moisture as the temperature decreases. You may pay an ice dam removal company to melt the ice dam off your roof only for the leaking to continue.

Ice frost and other condensation need to be removed from your attic. Depending on the temperature and the insolation ie. And the same factors that cause attic condensation problems also cause ice build up on roof edges which can lead to ice damming. The melt water runs down the length of the roof to the eaves where it refreezes forming a dam and icicles.

Can sun get to the roof you will have either frost or water collecting. If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof deck. Attic condensation during the winter can decrease the effectiveness of insulation and over time can cause significant damage to structural elements in the attic such as rafters or trusses.
