To Vent or Not to Vent: Why Roofing Ventilation is Important

Tuesday, September 9th, 2014 by Office

According to Angie Hicks, the founder of Angie’s List, the Federal housing Administration suggests that there should be at least a square foot of ventilation for every 300 square feet of your attic. Despite this recommendation, many Washington DC roofers note that there are still many attics across the United States without proper ventilation.

Structural Integrity

Without proper ventilation, the temperature in the attic may rise to about 150 degrees or higher. Insufficient ventilation may make your roof damper and hotter, causing your shingles to weaken. Furthermore, it may lead to other problems, such as mold and mildew formation, and condensation build-up.


Proper ventilation helps you avoid serious health problems. Research shows that many people who live in modern, properly insulated houses with central heating systems often experience air pollution about 10 times worse than when they are outside. Having a low-grade or an inappropriate ventilation system puts you and your family at greater risk of exposure to bacteria, viruses, mildew, mold, fungus, and harmful gases.


Ventilation systems are essential because they balance the temperature inside the attic with the temperature outside. This is evident during winter, where the cool air that enters through vents assists in avoiding the formation of ice dams. Proper ventilation systems also prevent increase in humidity. During summer, you need proper ventilation, as it keeps your roofs at a cool temperature despite the heat.

You can avoid all these problems by having the right materials and working with the right roofer in Washington DC who can install the ventilation system properly. Roof ventilation is important, as it help you avoid frequent roof repair and maintenance.
