Basics about roof ventilation

Roof ventilation is truly vital for every home. The fact is that proper ventilation can save the roof for many years and ensure its good condition. On the other hand, if a roof lacks adequate ventilation, moisture may be trapped inside the roof and it can degrade faster. What is more, energy bills can accumulate and lead to more serious issues in any house where the roof ventilation is not taken as a serious issue. We asked professional roofers from DNB Construction, LLC about roof ventilation basics.

To start with, roof ventilation keeps a roof dry and the temperature stable. Also, adequately done ventilation lets the warm air leave the attic as soon as it arises after doing laundry or showering. On the other hand, poor ventilation can cause wet air to make mold grow. The result may be an obligatory complete roof replacement, in the end, as the only way to totally get rid of the damage. What is more, poor ventilation may cause accumulating heat that leads to premature roof aging and its degrading. In winter, the warm air that is collected inside the attic brings about uneven snowmelt that may lead to developing ice dams, as well.

Is it easy to see if your roof is properly vented?

Well, it’s not. But, there are some signs that may help. Some of them are:

  • Different temperatures between the outside and attic
  • Mold in the attic
  • Blistered roof shingles
  • Ice dams
  • Moisture and frost in the attic

Experienced roofers from DNB Construction, LLC explain that proper roof ventilation brings numerous benefits. It is good to know about the main elements and terms connected with roof ventilation. Knowledgeable roofing technicians usually suggest some of the following techniques regarding roof ventilation.

  • Air sealing – it’s a technique used by roofers to prevent airflow, moisture, and heat to travel between the outdoors and attic.
  • Ridge vents – are installed along roofs’ ridges with the goal to provide ventilation. Additionally, ridge vents come in many lengths and widths.
  • Soffit vents – are perforated and then fitted between rafter tails to ensure good airflow and roof protection from moisture and ice buildup.
