Attic and roof ventilationThe Importance of Sufficient Roof Ventilation


Are you paying more than you should on your energy bills? Has there been any mold on your ceilings or attic? Do you frequently deal with ice dams in the wintertime? Well, if you’ve answered yes to either of these, then you most likely have roof ventilation issues. Any good contractor in the industry will tell you the importance of sufficient roof ventilation.

To prevent mold growth, ice dams, and outrageous energy bills, you’ll want your roof to be properly ventilated. Ventilation is established on the principle that heat rises. Proper ventilation results in your attic space matching the humidity and temperature of the outdoors. In doing so, you’ll be able to avoid a litany of issues.

Energy Efficiency

We’ve mentioned some of the previous issues with poor ventilation, but nothing is more pressing than additional costs. Any shortcomings with roof ventilation your air conditioner and heating unit will have to compensate by working overtime, therefore shortening your HVAC’s lifespan, and bloating your energy bill. 

Ice Dams

Ice dams form when the higher areas of your roof are above 32 degrees Fahrenheit (above freezing) and the lower areas are below 32 degrees Fahrenheit (below freezing). Accumulating snow melts at the high points of your roof then flows down until it reaches a valley or gutter and freezes, preventing your roof from draining properly. 

Ice dams could lead to a variety of different problems. The best way to prevent ice dams is a properly ventilated roof, therefore there’s no abundance of hot air to melt the snow atop your roof. For more information about ice dams, click this link here.

Mold and Decay

Mold grows from the presence of moisture and excessive amounts of humid air. Most ceilings aren’t entirely sealed, so it’s the perfect breeding ground for mold exposure and rot. Most home and business owners know indoor molds can cause several serious health problems, and not to be taken lightly.

Mold and mold spores can even deteriorate the supports and structure of your roof. Which could lead to potential leaks and water damages. 

Pathway to Good Ventilation

Genuine ventilation takes place when cool air can enter the attic space near the eaves of the roof, and exit near the peak. So you’ll want only the best materials and products to ensure your roof stays ventilated in the long term. 

  • Soffit vents work best for the intake of air
  • Air can easily pass through ridge vents
  • Gable vents are great at allowing air in or out, however, they don’t exactly specialize in helping airflow throughout the attic space
