Importance of attic ventilation
Experts in roof maintenance like to preach about the importance of attic ventilation. And it is not an exaggeration. It really does matter for many reasons. For starters, below are the merits of improving the flow of air beneath your roof according to the team at John Peters Roofing.
Top 4 importance of attic ventilation
It Inhibits Condensation
Condensation is when moisture turns from gas to liquid. It happens only when wet warm air meets a colder surface, which is why a bottle of soda sweats after leaving the fridge.
In roofing, condensation is a fate-sealing phenomenon. Water (of any amount) could compromise the structural integrity of a building material. Without enough ventilation in the attic, extreme moisture could render nails rusty and wooden decking boards rotten.
It Slows Down Shingle Aging
Extreme heat could increase the temperature of the bottom side of asphalt shingles, wearing their materials out more quickly. Curling is indicative of shingle damage due to extreme attic heat trapped in a poorly ventilated attic.
It Prevents Ice Damming
Ice dams form when the roof is warmer than the frigid outside temperature. Experienced roofers would admit that clogged gutters increase the chances of ice damming, but nobody would deny that poor attic ventilation is always the primary cause.
With sufficient ventilation, any heat that manages to pass through insulation and reach the attic will be expelled to the outside. As a result, the temperature of the attic, and so is the roof above it, will stay close to the outside air.
It Helps Keep the Roofing Warranty Valid
Did you know that an inadequately ventilated attic could void a roofing warranty? As mentioned, poor ventilation is responsible for many causes of roof damage. The real enemies of a roof, like the elements, are unavoidable. But a lack of airflow in the attic is a product of neglect in the eyes of a roofing manufacturer.
