Residential Roofing: What is the Importance of Attic Ventilation?

Although it may seem rather counter-intuitive to insulate your attic to keep it warm, and then install vents to allow air in from outside, attic ventilation is an important step one should take for reducing moisture, avoiding mold, and preventing formation of ice dams. It is important to keep in mind that your attic and the way it vents and breathes can have a significant impact on the life of your roof system. You should consult a reliable professional in residential roofing in Sonoma County to find out more about the importance of ventilating your attic.

Why Attic Ventilation Matters

A balanced attic ventilation system consists of intake at the eaves, fascias or soffits of the roof, and exhaust near or at the roof ridge. Such a system serves two extremely important functions:

  • It allows fresh, cool air to enter the attic.
  • It facilitates the escape of hot, moist air.

Even though you need to have a balanced ventilation system in your attic to regulate temperature throughout the year, it is especially crucial during the hot summer months, when the sun heats up your roof, and causes more build-up of heat in the attic. When there is no proper ventilation, it can contribute to the build-up of heat and moisture in the attic, and even result in the increase of the temperature in your living space. Excessive moisture and heat can lead to damage to shingles, ceilings, wood framing, siding, and paint.

During the cold season, improper attic ventilation can contribute to the formation of ice dams. This takes place when the snow and ice on your roof melt from an excessively warm attic, and then refreeze at the gutters, and build along your eaves of your roof, and ultimately form a dam. When it melts, water can flow under the shingles on your roof and down the deck into your home through the windows, walls, and/or ceilings. When you have proper attic ventilation, cold air mixes with and cools the hot air inside your home, and this in turn slows down the snow-melting process and helps in reducing the risk of the formation of ice dams.
