Why do Metal Buildings Have Roof Vents?

metal building roof vents
When designing, planning, and pricing your metal building kit, there are various accessories you can add to the design. Some metal building roof vents are incorporated with climate control systems. These would include steel building heating, insulation, and air conditioning installed in the ceiling.

Adequate ventilation is vital in protecting steel buildings from moisture damage. Unlike non-metal facilities, steel structures have a high risk of forming condensation due to the high conductivity of metals.

Metal building’s roof vents allow fresh air to enter and circulate across the interior, eliminating excess moisture and heat.

Types Of Metal Building Roof Vents

Not every roof vent can offer adequate ventilation for a big metal building since various types of vents offer different ventilation levels.


They are ideal for small prefab steel structures. However, when combined with turbine vents, they can be valuable in more prominent buildings.

Ridge Vents

These type of vents are installed at the roof’s top ridge. They are pretty expensive compared to the other types of air ducts. Ridge vents offer the highest level of ventilation per square foot.

Circular Vents

Unlike circular vents, you can only install some metal building roof vents on a roofing system with a particular slope. These vents can be modified and installed on almost any hill. 

Benefits Of Metal Building Roof Vents 

Lowers Indoor Pollution

Human beings spend 90$ of their time indoors every day, including the number of hours we spend in vehicles. According to Environmental Protection Agency (EPA) findings depending on your location, the indoor air quality can be five times worse than the outside air.

EPA indicates that recently the concentration of indoor air pollutants has increased due to various factors, including high use of synthetic construction materials, personal care products, furnishings, household cleaners, and pesticides. Also, energy-efficient construction lacks enough mechanical ventilation to allow air circulation.

Metal building roof vents allow air to circulate as the wind blows over your roof naturally. An exchanger pulls out the interior air that might contain pollutants.

Important Balance

The air temperature on the roof will always be higher, mainly during the summer months, because warm air rises. A ridge vent will allow warmer air to escape and cause natural airflow. 

During cold months the vent design prevents the warmer air from escaping via pressure exerted by cold air from outside. Metal building roof vents are pretty helpful in areas with high humidity—the system assists in eliminating the condition that’s that forms mildew and mold. In addition, roof vents prevent the problem of condensation from forming on the windows, especially during cold seasons.

Keep Away Unwanted Guest

Current roof vent designs provide excellent airflow without attracting squirrels, rats, and other rodents to your metal building. Previously, roof vents required the installation of a screen or trap that hindered efficient airflow. 

Metal building roof vents play a significant role in airflow circulation in the building. As clean air enters via the roof vent to the lower parts of the building, steady air circulation is created. This then allows elimination via the metal roofing ridge vent system.
