Ventilation is a very important aspect of your roofing system.
Without adequate ventilation, moisture will accumulate in your home, rise to the attic and cause damage to your roofing system.
Homeowners consider the effects external moisture has on their roof, but very few think about the internal moisture and its effects.
Moisture such as rain, ice, and sleet are commonly considered when choosing roofs but not enough attention is placed on the ventilation system and ensuring that internal moisture has an adequate way to evaporate so not to cause damage to the roof shingles or sheathing.
Ridge vents work by allowing air to blow through the vents, which in turn, draws out the moisture that has risen to the attic. This is referred to as a balanced ventilation system and is vitally important to the maintenance and well being of the roofing system. The ridge vent is installed along the top of the roof and is best when installed with an underlying venting system.
To ensure that your roof will be best served with ridge vents, have a professional roofing contractor inspect your roof to determine if your roof is a good match for ridge vents. Some roofs are extremely steep and may need additional ventilation to ensure good balance.
Ridge vents work throughout the seasons, year round, are not affected by the direction of the wind, and have an appealing look to your home.
