Regardless of the climate, commercial roof ventilation is vital in keeping a building properly ventilated. Humidity and hot air will always rise to the highest point of a building. If it doesn’t have anywhere to go it can cause a variety of problems. Having the right ventilation system in your commercial building will help prevent these problems from occurring and save your pocketbook from unwanted expenses. 

Understanding Roof Ventilation

The idea of roof ventilation is to ensure a continuous flow of air in a space to prevent overheating and/or accumulation of moisture that can cause damage. It also helps reduce fluctuating temperatures within the building. In order for roof ventilation to be effective, however, it’s important to understand the needs of the building space. 

First, there needs to be plenty of air space to enable airflow under the roof and eaves. Second, the roof ventilation system should be able to balance the intake and exhaust ventilation under the roofing.  A roofing contractor will be able to help determine what the needs of the building are in order to determine the best roof ventilation system. 

The Benefits Of Commercial Roof Ventilation

Reduce Energy Costs

During warmer months, hot air will rise within a building becoming trapped which can then cause your A/C system to work overtime to keep the inside air at its desired temperature. Having a commercial building properly ventilated allows for this hot air to escape so that the cooling system doesn’t have to work overtime and in turn reduces energy costs. 

Helps Prevent Mold 

Once mold begins to grow it spreads very quickly. Areas that get a lot of moisture in the air are more prone to mold growth making it even more important to have proper roof ventilation. Since mold can cause health problems, owners of commercial buildings need to ensure that mold doesn’t become a problem for the safety of staff and anyone else who enters the building. 

Not only does mold affect humans, but it also eats away at materials within your roofing system which lead to corrosion, decay, or rot. Even if mold does not take hold, moisture alone can damage roofing materials. Having proper ventilation is pivotal in preventing damage to the roofing structure and in the best interest of those who operate within the facility. 

A Longer Lifespan

Roofing systems are made to last for at least a few decades but will be dependent upon the right ventilation as well as roofing maintenance. Besides the issues mentioned above, not having proper ventilation can lead to a variety of roofing issues such as warping and/or losing shingles which will be dependent on which type of roofing system you have. Ensuring the right roofing ventilation for your roofing system will contribute to a longer lifespan. 

Different Types Of Commercial Roofing Vents

Mechanical Vents– Mechanical vents can be paired with non-mechanical vents as they tend to increase energy costs. However, this ventilation system is used in many modern commercial buildings as they give a streamlined aesthetic. They can be utilized as single-point or multi-point systems depending on the size of the building. 

Static Vents– This type of ventilation system is popular for flat and metal roofing systems. They come in a variety of styles and are installed in an even line across the roof. 

Ridge And Eave Vents– Ridge vents prevent heat buildup and moisture accumulation. They are also installed to blend with the roofing system making them the first choice for roofers. Eave vents allow for fresh air to enter a building which helps reduce the heat build-up and provide better air quality. Combining both of these ventilation systems is the most effective way to ventilate a building. 

Gable Vents– These vents are best installed with other vent systems as they are prone to hot spots due to the fact that they are installed under the roof. Static or ridge vents are typically used in conjunction with gable vents. 

Understanding the needs of your commercial building is the first step in determining which roof ventilation system will be the best to use for your building. Call your local roofing contractor to help you with your commercial roof ventilation needs.
