A good roof has a system of intake and exhaust vents. These components ensure that there’s proper airflow beneath the roof, modulating its temperature during the hottest and coldest months.
There are many ways to configure roof ventilation, and the jury is still out on whether which way is the most effective. But one’s thing is universal: adequate ventilation is a must. Here’s what it can do for your roofing system.
Inhibiting Shingle Curling and Blistering
Sufficient airflow is necessary to expel heat and moisture, two factors that can accelerate shingle deterioration.
Trapped warm air can heat up the bottom of shingles, causing them to curl and wear out prematurely. Excessive moisture trying to exit the house through the roof can dislodge the protective granules of shingles.
Well-designed vents are the lungs of your roof. They make sure the air circulating in the attic is cool and dry so that you have one less thing to worry about and decrease your roof repair costs over time.
Preventing Ice Damming
Good ventilation lets snow build up atop of your roof instead of causing it to melt and refreeze by the gutters. Snow buildup is a problem in itself, but it’s easier to manage and less hazardous than sharp icicles hanging along the edges of your roof.
Ice dams can become heavy, and their weight is concentrated on small areas. When they begin to melt, they can cause water to back up and seep into the roof or fall without warning.
Discouraging Mold Growth
You can keep mold from invading your home with proper roof ventilation. It helps control dampness, so it’s an elegant solution to keep mold growth in check.
