Why Attic Ventilation is Important for Your Home in the Winter

A well-ventilated attic in your home is essential for your comfort and safety throughout the cold months. Attic ventilation in winter helps protect the roof structure from getting damaged by moisture. Upgrade your attic ventilation to enhance the indoor air quality and improve the overall condition of your home this winter.

Why Attic Ventilation Is Important?

Your attic vents do more than just releasing excessive heat in summer; they also discharge extra moisture from your attic in winter. Over time, the warm and humid air in your attic can encourage the development of mold and mildew. If left alone, these can have an adverse impact on the health of your family, and the structure of your roof deck, and the attic. Attic vents also protect your roof by stopping and preventing ice dam formation on your roof. The ice dam accumulation can cause damage to your gutters, roof deck, and shingles. Therefore, ensuring proper attic ventilation helps protect your home against many problems and makes your living space comfortable.

How to Improve Attic Ventilation?

Adequate attic ventilation helps in keeping your attic at the perfect temperature and circulate the air that goes in and out of your attic. For every 300 cubic feet of attic space, you should have one square foot of ventilation. This allows air to circulate without any restrictions; it maintains the moderate temperatures and low moisture levels. Keeping your air moving not only controls temperature, it continually brings fresh air in, while pushing the stale air out.

Non-traditional solutions to maintain proper attic ventilation in winters

Here are a few options available for ventilating your attic space:

  • Intake vents, like gable vents, under-eave vents, and rafter vents, can be installed in the gables or peaks of your roof, the eaves, or the rafters.
  • Exhaust vents, like ridge vents and turbine vents, are just as important because they help to cool the space down by allowing the hot air to escape.
  • Attic ventilation fans provide mechanical ventilation, by drawing in cold, outdoor air and expelling warm, moist air out.

Bottom Line

Attic ventilation works to maintain both temperature and air quality. Keeping temperatures in a more neutral range, reduces the risk of damage due to mold or moisture, wood rot in the rafters and ceiling joists, and also help protect the shingles of your roof. Residential HVAC service providers offer installation and maintenance of attic ventilation to help you keep your home in top condition throughout the year, especially in the winter season.
