Understanding Attic Ventilation for Optimal Roof Performance

At Brothers Roofing and Construction, we believe that knowledge is power when it comes to maintaining a healthy roof. Today, we’re diving into the often-overlooked but crucial aspect of attic ventilation and its impact on your roof’s lifespan.

Why Attic Ventilation Matters

Proper attic ventilation is essential for several reasons:

• Temperature regulation
• Moisture control
• Prevention of ice dams
• Extended roof life

The Technical Details

Attic ventilation works on the principle of convection. As hot air rises, it creates a natural flow that can be harnessed to maintain a healthy roof system. Here’s how it works:

1. Intake vents: Located at the lower part of the roof, typically in the soffit or eaves
2. Exhaust vents: Positioned at or near the roof peak
3. Air flow: Cool air enters through intake vents, pushes hot air up and out through exhaust vents

Calculating Proper Ventilation

The general rule of thumb is 1 square foot of ventilation for every 300 square feet of attic floor space. This ratio ensures adequate airflow to prevent heat and moisture buildup.

Types of Ventilation Systems

There are several ventilation options available:

• Ridge vents
• Soffit vents
• Gable vents
• Power vents

Each type has its advantages, and the best choice depends on your specific roof structure and local climate conditions.
