Typical Winter Roofing Problems and How to Avoid Them
February 6, 2023
What is active roofing ventilation? If you are building a new house or thinking of renovating your current home, then one crucial decision you have to make is the type of attic ventilation to install. The type of roof ventilation that you install in your house matters because it determines how air circulates and your home’s energy efficiency.
Proper ventilation also affects your roof lifespan and helps to ensure that your house is habitable during extreme weather like in the summer. One of the main types of roof ventilation is active roof ventilation. So, what exactly is active roof ventilation, what are its benefits, and is it worth installing it on your house? In this article, we will tell you everything you need to know about active Roofing ventilation to help you make an informed decision.
Now without further ado, let’s get started
What is Active Roofing Ventilation?
Active Roofing ventilation is simply a type of roof ventilation that uses a fan blade, turbine, or motor to exhaust air from the attic. Active Roofing ventilation usually exchanges the stuffy air inside the attic of your property with fresh air from the outside at a faster rate compared to passive roof ventilation.
This is because the flow of air in active ventilation is more consistent and predictable compared to the flow of air in passive roof ventilation. This is because active roofing ventilation depends on electricity to run as opposed to unpredictable natural elements. If your house is well insulated and designed, then you can use active roof ventilation only in areas where moisture is generated such as the laundry area, bathroom, and kitchen.
This type of ventilation can also bring in the fresh air in damper and cooler rooms like the south-facing rooms. This type of ventilation can also come in handy in ventilating rooms that collect excess heat.

Active Roofing Ventilation vs. Passive Roofing Ventilation- What is the Difference?
Active and passive roofing ventilation are the two main types of roof ventilation. The main difference between these two types of roof ventilation is that in active roof ventilation, the air is circulated to indoor spaces using mechanical fans. As a result, this type of ventilation provides a more consistent ventilation system for your home or business because it does not depend on natural air currents.
On the other hand, passive roof ventilation provides air circulation via natural methods such as air current and buoyancy. This type of roof ventilation uses air vents to guide and control air circulation. Because passive roof ventilation depends on natural air currents, it is usually less consistent in ventilating a property compared to active roof ventilation.
Benefits of Active Roofing Ventilation
Perhaps the main benefit of active roof ventilation is that it provides a more consistent ventilation system and that is why it is mostly installed in commercial buildings. Active roofing ventilation is more predictable and consistent. Unlike passive roof ventilation which is usually at the mercy of natural air currents, which make them inconsistent, active roof ventilation is powered by mechanical fans. They usually deliver constant air flow regardless of natural air currents. Active roof ventilation is not susceptible to elements of weather.
It Actively Works to Create Airflow
Active roof ventilation usually works hard to create airflow as opposed to just guiding natural air currents. This means that regardless of the weather condition, you are guaranteed that your home or office will have a constant flow of fresh air. That is why active roofing ventilation is highly recommended for rooms that have excessive heat as well as moist rooms like the bathroom and kitchen.
Final Thoughts- is It Worth Installing Active Roofing Ventilation?
Now that you know what is active Roofing ventilation, you may be wondering whether it is worth it to choose it for your attic. The answer is YES, installing active Roofing ventilation is totally worth it. Although the installation cost of active roof ventilation is quite high compared to passive roofing ventilation, active roof ventilation is more consistent meaning that you are guaranteed continuous air circulation in your home, regardless of weather elements. Active roof ventilation is always a better choice because it is more proactive at creating the ideal airflow needed to ventilate your attic.
