More Core Construction: The Critical Role of Attic Ventilation-Benefits & Solutions
When homeowners think about roofing, shingles and gutters often come to mind first. But at More Core, we know that what’s under your roof is just as important—especially your attic ventilation. Proper attic ventilation is a game-changer for your home’s comfort, efficiency, and the longevity of your roofing system. Here’s why it matters and how you can achieve it.
Why Is Proper Attic Ventilation So Important?
1. Lower Energy Bills & Improved Comfort
A poorly ventilated attic can reach sweltering temperatures—sometimes up to 170°F in the summer. This trapped heat radiates into your living spaces, making your air conditioner work overtime and driving up energy costs. With proper ventilation, hot air escapes, your attic stays cooler, and your monthly utility bills decrease.
2. Prevents Moisture Damage & Mold
Everyday activities like cooking and showering release moisture that can rise into your attic. Without adequate ventilation, this moisture gets trapped, leading to mold growth, wood rot, and damaged insulation—problems that threaten your home’s structure and your family’s health
3. Extends Roof Life
Excessive attic heat can warp roof decking and prematurely age shingles. In winter, warm air escaping into the attic can melt snow on the roof, which then refreezes at the eaves, forming destructive ice dams. Proper ventilation keeps the attic temperature closer to the outside air, reducing these risks and helping your roof last longer
How Does Attic Ventilation Work?
Effective attic ventilation relies on a balanced system of intake and exhaust vents:
- Intake vents (usually installed along the soffits) draw in cooler, fresh air from outside.
- Exhaust vents (placed at the roof ridge or high points) allow hot, humid air to escape.
This creates a continuous airflow, maintaining an attic temperature close to the outdoors and preventing heat and moisture buildup
Solutions for Proper Attic Ventilation
There’s no one-size-fits-all approach, but here are the most common and effective solutions:

How It Works |
Best For |
|
Soffit Vents |
Intake vents along eaves draw in cool, outside air |
Most homes; essential for balance |
|
Ridge Vents |
Run along the roof peak, allowing hot air to escape |
Homes with long roof ridges |
|
Gable Vents |
Placed on attic walls at gable ends for cross-ventilation |
Homes with gable roofs |
|
Roof Louvers/Box Vents |
Installed near the roof ridge to exhaust hot air |
Homes with limited ridge area |
|
Powered Attic Fans |
Electrically remove hot air when temperatures rise |
Homes needing extra airflow* |
*Note: Powered fans should only be used if your attic is well-sealed from living spaces and intake vents are clear, or they may pull conditioned air from your home, increasing energy costs
How Much Ventilation Do You Need?
The U.S. Housing Authority recommends at least 1 square foot of attic ventilation (split evenly between intake and exhaust) for every 300 square feet of attic floor space. Local codes may vary, so consult with More Core’s experts to ensure your home meets or exceeds requirements
