Roof Vents
What They Are and Why They Matter to Your Home
Every part of your home works together to keep it comfortable, efficient, and protected – and your roof plays a major role in that equation. A well-ventilated roof can help regulate indoor temperatures, reduce your energy bills, and preserve your roof’s lifespan.
Roof vents are the unsung heroes of roof ventilation, which help maintain airflow in your attic and prevent issues caused by excess heat and moisture. By improving ventilation, attic roof vents protect your home, your investment, and your peace of mind.
Curious about how this all works? Keep reading to discover why roof vents matter and how they contribute to the health and longevity of your roof and home.
The Power of Roof Ventilation Creates Healthier Homes
A cool, comfortable home starts at the top. Your attic might be out of sight, but it has a huge impact on the resilience and comfort level of your entire home. Effective roof ventilation works behind the scenes to control the temperature, protect your insulation, and reduce the strain on your HVAC system.
Roofing vents enable a steady flow of air, balancing cool intake air with warm exhaust to release trapped heat and moisture from your home. In the summer, temperatures in your attic can skyrocket like an oven, reaching up to over 160 degrees! Without a sufficient ventilation system, this superheated air can seep into your living spaces below.
In the colder months, everyday household activities like cooking and showering introduce water vapor into the air, which can rise up into your attic space. When this moisture has nowhere to go, it can condense on the underside of the roof deck and potentially seep into the insulation. Once excess moisture clings to insulation, it becomes compressed and loses its ability to balance the temperature.

Avoid Costly Damage with Adequate Roof Ventilation
By managing airflow year-round, roof vents keep your family cozy, your home more energy efficient, and extend the lifespan of your roof. But if your home lacks adequate ventilation, your roof and other structural components could face many damaging consequences. Below are some of the most common types of damage that can result from insufficient ventilation:
- Warped, cracked, or deteriorating wooden framing.
- Mold and mildew growth, which can spread through your home.
- Compromised insulation that impacts temperature control.
- Higher energy bills as heating and cooling systems work harder.
- Exterior siding, interior paint, or wallpaper damage caused by trapped moisture.
- Rotting wood that weakens the structure of your roof.
- Decreased air quality inside your home.
- Reduced lifespan of your roof.
Signs You May Need More Ventilation in Your Roof

Rising Energy Bills
Keeping cool indoors can sometimes feel like an uphill battle. If your roof isn't ventilated properly, heat lingers in your attic and radiates back into your home, driving up the temperature indoors. This overheated air forces your A/C to overcompensate, which can lead to noticeably higher energy bills.

Excess Moisture in the Attic
Warm air and moisture can easily get stuck in a poorly ventilated attic, creating an extremely hot and humid atmosphere. Wet insulation, warped wood, and even small mold spots are indications that airflow in your attic might not be up to par.

Warped or Damaged Shingles
Check your roof for cracked, curling, or prematurely worn shingles. If shingles are aging faster than expected or shedding granules excessively into your gutters, it could mean heat buildup is negatively affecting your roof. Well-placed house roof vents help lengthen the life of shingles by balancing temperatures.
How Much Ventilation Is Right for Your Attic?
A well-ventilated attic breathes life into your home – quite literally. You might not think much about your attic vents, but getting the right amount of airflow makes a big difference in keeping your home in good shape. Current guidelines and building codes recommend at least one square foot of attic ventilation (split between the intake and exhaust) for every 150 square feet of attic space. For example, a 750-square-foot attic would need five square feet of ventilation – 2.5 for intake and 2.5 for exhaust – to allow air to circulate efficiently.

Keep Your Roof Cool and Your Home Comfortable
A stuffy, overheated attic isn’t just uncomfortable – it’s working against your home. Ample roof ventilation is fundamental for Northern California homeowners, where hot summers can scorch your roof and attic. Without the right airflow, trapped air can lead to higher energy bills and unnecessary stress on your home’s structure.
