Attic Ventilation in the Winter
Proper ventilation in your attic is important to protect you and your home throughout the winter months. Ventilation in your attic during the winter protects the structure of your roof from moisture damage. Improving your attic air flow will keep your home in a good condition and also will maintain good indoor quality of air for the winter.
The Importance of Ventilation
Having the correct HVAC system protects against many home problems, ensuring that your home is comfortable indoors. Also, protecting your roof from moisture damage, such as:
- Moisture that can warp the roof
- Growth of Mold
- Rotting Wood
- Popped Shingles
- Dams of Ice
Your Attic During Winter
During the winter months, heat rises to the attic in your home and with heat comes moisture. When attics do not have proper ventilation, moisture will collect in that space of the home. Moisture will seep through the structure of the house, damaging your roof along with the framing and things in your attic. Having the correct HVAC in your attic will allow cool, dry air from the outside to flow into the attic, allowing the warm, moist air in the attic to escape. Good ventilation keeps the temperature even, preventing hot/cold spots that cause dams of ice where water can back up and freeze below the shingles of your home.
Having the correct HVAC during the winter will keep mold and mildew from growing, keeping your family safe from harmful bacteria and contaminants. Getting rid of moisture problems through ventilating your attic will improve the indoor air quality. It will also prevent warm, damp, and dark environments where creepy pests stay, keeping rodents and insects out of your attic.
Ventilation Problem Solvers
A HVAC professional may recommend one square foot of ventilation per 300 cubic feet of space. A ratio of 1:1 of intake and exhaust vents is what is needed to have good airflow throughout the attic. Vents in the roof allow the attic ventilate on its own but a HVAC professional can offer mechanical solutions as well.
Intake Attic Vents
Intake attic vents help air to flow into the attic. Three main types of intake vents for better attic ventilation in the winter are:
Gable vents: These vents are installed at the peak of the roof, which is the highest point of the gable. Some people choose to paint them in a number of different styles are to blend with the home’s outside appearance. The gable can serve as intake and for exhaust, depending on the direction of the wind.
Under Eave Vents: These under-eave vents are a continuous vent that is put in under the eave of a home. The vents can be covered easily by the insulation in the attic. Be sure that the insulation is not installed covering any of the vents.
Rafter Vents: Rafter vents work in relation to the under-eave vents to give clear, clean air flow to the under-eave vent. These are installed along side of the attic’s rafters, centered at the place where the ceiling and the floor of a attic meet.
