Attic ventilation isn’t something that probably usually crosses your mind. However, your roof’s efficiency, durability and longevity largely depend on it. With good air circulation, outside temperatures are less likely to affect your living space, and your roofing system will last longer.
Here are more reasons roofs need proper attic ventilation.
To save yourself from costly energy bills. Proper ventilation helps eliminate excess moisture and heat from your attic. Extended exposure to heat and humidity can accelerate the deterioration of the roof sheathing. It can also cause the shingles to warp and fail early.
Without an efficient ventilation system, the heat from the sun will transfer to your living space, making it more difficult to cool and heat your home. In addition, when your HVAC system has to work harder, it consumes more electricity, causing your energy bills to increase.
To prolong the life of your roof. Humidity can come from without as well as from within your living space. When humid air travels to a cool attic in the winter, it will become liquid when it comes into contact with colder surfaces. Excessive moisture can cause roofing components to deteriorate, the roof’s structure to become damaged or your attic insulation to become compromised. If your attic is warm, moisture will create an environment conducive to mold and mildew growth. That said, one of the best ways to extend the life of your roof is to maintain good attic ventilation.
To prevent ice dams. Uneven attic and roof temperatures are the main causes of ice dams in the winter. These ice formations can develop when snow from the warmer upper areas of your roof melts and refreezes when the water reaches the much colder outer edges.
