Why Attic Ventilation Is Important

You might not give your attic that much thought, but it plays a role in keeping your roof intact. As long as it is well-ventilated, you can be sure of your roof’s health and performance throughout its lifespan. Not only that, but it can also help maintain consistent indoor comfort in your home. Here’s why having proper attic ventilation is a must. 

Prevents Shingle Deterioration

When there’s excessive heat outside, your roof sheathing may likely warp. This will also cause your shingles to prematurely age, forcing you to have them replaced even before the near end of their 20-year lifespan. With a properly insulated and ventilated attic, the heat from the roof will not radiate down to your living areas. This prevents your HVAC system from having to work twice as hard to keep your home’s 

Stops Ice Dams From Forming

Ice dams form when the bottom layer of snow on your roof melts and trickles down to your roof’s cold outer edge where it refreezes. When this happens over and over again, melted snow starts to back up under the shingles where it causes moisture damage. You can stop ice dams from forming in the winter by making sure your attic is well-vented and insulated.

Discourages Mold Growth

You don’t want moisture to accumulate inside the attic. However, if it is not well-ventilated, its presence may help create an environment where mold and mildew can grow. As long as condensation continues, these organisms can spread throughout your home. Ensure adequate ventilation in your attic to reduce respiratory issues caused by the spread of mold spores throughout your home.
