Are you getting a new roof and confused about what roof ventilation is? It is an extremely important part of any roof install and you want to make sure it is done correctly. Let’s take a look at what roof ventilation is, how it works, and why it is so important.

What is Roof Ventilation?

Roof ventilation is what allows air to flow through your attic space. This air escapes through roof vents. If this is done properly, it is what protects the roof from overheating and or condensation developing. If a roof overheats or moisture builds up it can lead to damage or potential health risks. Some of these potential risks are mold, ice dams, and higher energy costs.

Creating Airflow

There are many different roof ventilation systems, but they all create airflow. Some of these systems require airflow, some are powered by wind, and some circulate the air passively.

Types of Roof Ventilation

Due to different climates, homes are all designed differently and their roof vents are too. This means you need a custom ventilation system that works for your home. The different types of roof ventilation systems are wind turbines, box vents, soffit vents, and ridge vents.

How Roof Ventilation Works

Air needs to be able to naturally flow through the attic. When hot air rises into an attic this creates pressure in the high points of a roof and the hot air will escape through the roof. This can only happen when there is a way for cold air to flow into the attic. When wind hits a roof it increases the intake as well as the exhaust. Whichever vent you use, the idea stays the same. Roof vents work to allow air to circulate in the attic to regulate temperatures. When your roof ventilation is installed consider the right number of them due to the size of your home so proper ventilation takes place for the intake and exhaust. A good rule of thumb is that you can never have too many. Typically you need one vent per 300 sq. feet.

Benefits of Roof Ventilation

It is essential to have roof ventilation. You want your roof vents working for you throughout the year. Proper ventilation will extend the life of your roof by keeping the shingles at a more moderate temperature. In the warmer months, the vents will allow for circulation so hot air can escape.

In Conclusion

While considering a new roof or booking your roof replacement takes time to account for your roof ventilation. Every homeowner should understand what a roof ventilation system does for them. When this is done correctly, you will see a great benefit. For more information on the types of roofs and the ventilation that will work best for your home, contact us.
