What is the Best Roof Venting Option?

Neglecting your roof ventilation can result in some serious issues in your home including water damage, mold growth, and rotten decking, to name a few. So, what is the best roof venting option? Not only are these issues expensive and time-consuming to fix, but they are hazardous to your health. That’s why you should consider replacing your box vents at the time of roof replacement. By doing so, you can avoid the potential risks associated with inadequate ventilation and keep your home cool, dry, and comfortable all year round.  

In this article, HUDCO Roofing discusses the following:

· A detailed explanation of the two primary forms of attic ventilation systems.

· Whether you should consider replacing your box vents when replacing your roof. 

· The best roof vents options available on the market. 


What are the different kinds of Roof Ventilation Systems? 

You have two main types of ventilation systems to choose from: passive and active. While both systems are effective, they differ in their approach to achieving proper ventilation. Understanding the difference between these two ventilation systems can help you make an informed decision when it comes to upgrading your roof ventilation.

Passive Roof Ventilation

Passive roof ventilation, which includes box vents, is a more commonly used system. Contrary to active vents, these vents do not rely on a motor, turbine, or fan blade to circulate air. Instead, they rely solely on natural air circulation. This means that the airflow in your attic is determined by a variety of factors such as the temperature, wind speed, moisture content, height of your attic, and roof pitch among others. 

Active Roof Ventilation

Active ventilation employs a motor, turbine, or fan blade to achieve optimal attic airflow, functioning similarly to a fan. In this case, the spinning blades draw air out of the attic while intake vents allow fresh air to enter your space. This creates a consistent airflow that replaces stale air with outside fresh air continuously. 

While box vents are a common and affordable option, they are unfortunately not that effective. That’s why, choosing an active ventilation system can help you get better results with more consistent airflow. 

Upgrading Box Vents? Your Best 4 Options

1. Power Vents

If you choose to install power vents on your roof, you should be aware of their potential drawbacks. While power vents are effective at removing hot and stale air out from your attic, they require a humidistat during the winter months to prevent the buildup of moisture. In the absence of a humidistat, the moisture levels in your attic may rise and contribute to rotten decking and mold growth. 

2. Turbine Vents

Another good option is the use of turbine vents. These vents operate on the principle of convection. As warm air rises upwards in the attic, the spinning turbine vents remove the stale air out from your attic. Such ventilation systems can circulate the air in your attic between 10 and 12 times every hour. They are highly effective for removing excess heat and moisture from any space. You can consider this option when choosing the best upgrade for your box vents.

3. Solar Powered Vents 

Solar power vents can help you harness the power of the sun to save money on electricity bills while maintaining a comfortable temperature in your home. However, on the downside, these vents rely on a solar-powered battery which requires time to charge. As a result, the vent may turn off during this charging period. Furthermore, the battery’s charge may not last for the entire day. 

4. Ridge Vents

If you’re looking for a concealed roofing ventilation system that won’t be visible from the ground, ridge vents are a great option. These vents are installed along the ridge or top of your roof and extend their entire length. Although they won’t be noticeable from the ground, ridge vents do have a filter that is not highly effective. This means that you may need to take extra measures to keep insects and rain out of your attic space. However, if you prefer a discreet ventilation system, ridge vents may be the right choice for your roofing needs.
