Active vs. Passive Roof Vents: Which Is Best for Your Home?

Published by Pickard Roofing at

Though it may not be the most flashy part of your roof, vents play a vital role in its longevity and performance. Your attic’s ventilation is a system that allows your house to breathe. Without proper attic ventilation, your roof’s life will be cut short and your energy bills will be high. Not to mention, it can also affect your home’s thermal comfort and energy efficiency. With so many different types of vents on the market, choosing the right one for your needs can be challenging. Here are some factors you should keep in mind during your search.

Active Roof Vents

A well-ventilated attic is essential to the health of your home. An active roof vent system helps to ensure that your attic will stay free of moisture and mold by drawing fresh air in from the outside and pushing the hot, stagnant air out.

The system works by creating a negative pressure in the attic, which causes the fresh air to be drawn in through the intake vents. The exhaust vents then release the hot, moist air to the outside.

In addition to preventing moisture and mold growth, an active roof vent system also helps to keep your home cooler in summer and warmer in winter. By circulating fresh air through the attic, it helps to regulate the temperature and prevent drafts. As a result, an active roof vent system provides many benefits for your home.

Passive Roof Vents

The passive vent is a type of roof vent that employs natural air movement to keep the roof dry and cool. It is generally less conspicuous than an active vent because it seamlessly blends in with the shingles on the ridges.

The passive vent does not rely on any power sources, but instead uses the natural movement of air to create ventilation.

The passive vent is generally less expensive than its active counterpart, and multiple vents can be placed along the length of the roof to provide better results.

Passive vents are also handy because they don't need electricity or sunlight to run.

Choosing the Right Roof Vent for Your Home

When it comes to selecting the right roof vent for your home, there are several factors you should consider. Do you need a more powerful system that can move large amounts of air? Or do you prefer something less conspicuous and more affordable?

Active vents provide greater ventilation and temperature control, but passive vents may be better suited for cost-conscious homeowners. The choice ultimately comes down to your personal preference and budget.

No matter which type of vent you choose, make sure to have a professional roofer install it for optimal performance. A properly installed roof vent will ensure that your home’s attic stays healthy for years to come.
