What Is Good Attic Ventilation

The purpose of attic ventilation is to move air around in your attic and allow warm moist air to dry or escape.  It doesn’t help if your attic ventilation is only good in certain areas of the attic.  Partial ventilation will result in areas of moisture and damage to your roof or materials and structures in your home.  Good attic ventilation whether it is natural or mechanical allows air to move in the entire attic and protects your home from water damage, mold and ice dams.

The Importance of Attic Ventilation in the Summer

In the summer, your attic will get extremely hot if you don’t have proper attic ventilation.  Temperatures over 100 degrees is not uncommon.  Moisture and heat in the attic can cause damage to your roofing system and shorten the lifespan of your roof and shingles.  This hot air can also cause temperatures in the living area of your home to be hot.  This results in your appliances running longer and less efficiently.  Air conditioners, fans and refrigerators may run longer and wear out quicker too.  For this reason, you need good attic ventilation to lower your utility bills.

The Importance of Attic Ventilation in the Winter

In the winter moist warm air rises into the attic from your home.  This warm air will condense on colder surfaces.  This can cause nails and other metal in your roofing system to rust.  It can also cause your decking to swell often resulting in your shingles buckling.  Your deck can also rot and become unstable.  Water dripping into your insulation can cause ceiling damage and damage to the insulation.  Mold and mildew can become a problem too resulting in poor air quality throughout the house. 

Preventing ice dams is another reason why you need good attic ventilation.  Warm air seeping through the surface of the roof along with the suns rays can cause snow and ice to melt. This results in water accumulating at the eves and valleys of your home.  At night the water refreezes.  This cycle continues during cold weather and often creates an ice dam, which could collapse your roof.

Why You Need Good Attic Ventilation
