Air pollutants are often 2-5 times higher indoors than they are outdoors. The best roof ventilation methods can help promote better indoor air quality, which can contribute to better health as a result.
But did you know that roof ventilation can also help reduce your energy bill and extend the life of your roof?
In this guide, we discuss the different roof ventilation options. Continue reading to find out how your home can benefit from the right system and how to choose one.
What Is Roof Ventilation?
Before discussing your roof ventilation options, it’s important to understand what it is. The different roof ventilation types create a system of vents that help create air circulation inside your home.
These ventilation systems help prevent hot air from getting stuck in your house and attic. Heat can create several problems including the build-up of condensation. This can be bad for your home as well as your health.
Advice About Roof Ventilation
Our advice about roof ventilation is to ensure you have a quality system. When hot air and condensation are trapped in your home, they can create problems such as mold, rot, and damage to your shingles.
The best roof ventilation methods can reduce energy costs, manage temperatures, and extend the life of a roof. When air is properly circulated your heating, ventilation, and air conditioning systems work less hard.
Roof Ventilation Types
There are many different roof ventilation types and they fall into two basic categories: active vents and passive vents. Both types of ventilation require intake vents and exhaust vents for optimal circulation.
When deciding between your options, consider your house size and desired vent appearance. You’ll need 1 square foot of roof ventilation for every 300 feet of attic space.
Active Roof Vents
Active roof vents are electrically powered. While they maintain more consistent airflow, they come with a higher cost and need more frequent replacement. Some common active roof ventilation options are listed below.
- Turbine vents
- Power vents
- Solar-powered vents
- Ridge vents with baffle
Turbine and solar-powered vents are more obvious while power and ridge vents offer lower profiles. Ridge vents sit along the length of your roof’s peak. They’re considered passive vents without a baffle to push air through.
Passive Roof Vents
Passive roof vents don’t have mechanical or electrical components. They allow air to flow through them naturally. These tend to be more cost-efficient than active vents but less effective in comparison.
- Box vents
- Ridge vents without baffle
- Gable-end vents
- Soffit vents
Ridge vents without a baffle are one of the best roof ventilation methods for passive vents. While less effective, box and soffit vents can be strategically placed to maximize flow. Gable-end vents rely on wind to create airflow.
