Proper Ventilation Can Save Your Roof

Most homeowners know that a well-functioning roof protects their family and their most important investment. However, they often overlook the importance of ventilation when it comes to maintaining the longevity and functionality of their roof.

Proper roof ventilation is critical because it prevents rot, leaks, and unhealthy air from circulating inside your home. This article will discuss what proper roof ventilation is and how it can save your roof from an early demise.

What is roof ventilation?

Roof ventilation is the process of circulating air both in and out of the attic and roof cavity. The goal of most roof ventilation systems is to ensure that cool, fresh air is circulating into the attic while warm and stale air exits the home.

Intake and exhaust vents

Roof ventilation systems typically employ two types of vents to circulate air properly. The intake vent allows fresh, cool air to enter the house, while the exhaust vent helps hot or stale air exit.

What happens if you don’t have proper roof ventilation?

Consequences of improper roof ventilation include:

• Poor indoor air quality: Without proper ventilation, pollutants and stale air can be trapped inside the home. Pollutant buildup in the attic can leak into the living space of the home and cause respiratory problems for those inside.
• Heat damage: If heat is not ventilated properly, it can become trapped below the roof surface. Excessive heat in the attic can lead to damaged roof shingles and underlayment.
• Rot and mold: Without proper ventilation, condensation and humidity take over and often lead to structural rot and mold growth. Rot is problematic for several reasons, but most significantly because it can contribute to the structural breakdown of the roof if not addressed early. As you probably know, mold can cause many health problems for those who regularly breathe in spores.

How do you spot poor ventilation roof damage?

In most instances, rot is the first sign of damage when a roof suffers from poor ventilation. So, be on the lookout for:

• Soft or squishy wood on the roof decking
• Leaks in the attic or near the walls
• Dark stained wood on or around the roof decking
• Sagging or curved roof deck
• Mold or mildew growth in the attic
