Industrial & Commercial Roof Vent Installation (Ultimate Guide)

 

Reducing the build-up of hot air in your roof cavity is greatly beneficial to your everyday comfort and well-being. Without proper roof ventilation, the hot air will be trapped and begin radiating through the ceiling and into the rest of your commercial building.

However, more than adequate ventilation requires a professional installation process you can trust your building with. Read on to learn more about commercial roof ventilation and how a high-quality system installed correctly can benefit you.

What is Commercial Roof Ventilation?

At its core, commercial roof ventilation is a system designed to provide optimal airflow throughout the roof space of a building. The ability to introduce fresh air into this space creates a healthy and efficient environment throughout your commercial set-up as pollutants are successfully removed.

How Does Roof Ventilation Work?

Natural ventilation systems operate through a series of intake and exhaust components, such as vents and fans. They are strategically installed throughout a roof space to remove hot air and introduce a fresh flow.

The process of operation in a natural roof ventilation system is as follows:

  1. Natural convection: In a building, hot air rises and gets trapped in the roof cavity. Without a means of being released, this built-up air can lead to occupants overheating and moisture damaging the structure.
  2. Intake vents: Specific intake vents are installed into your roof space to allow a source of cool, dry air to be introduced into the building. The location of these vents depends on your roof size, the type of vent product installed and the design of your building. However, the intake vents tend to be installed under eaves or soffits for optimal performance.
  3. Exhaust vents: Just as specific vent systems are required to allow fresh air in, there needs to be an exhaust system to allow unwanted heat and pollutants to exit. These vents tend to be installed at a roof’s peak.
  4. Pressure differential: The natural flow of air between intake and exhaust vents is encouraged by pressure differences. When cooler air pushes into a roof space, the hotter air is forced out, leaving an optimal indoor environment.

The passive airflow of natural vent systems means that this type of roof ventilation can continually occur without much oversight. It also does not require mechanical components or a source of power, making it a cost-effective method of venting any building with minimum maintenance.

Why Install a Roof Ventilation System?

Choosing to install a ventilation system into your roof cavity, attic space or other ceiling structures can offer a wide range of benefits. Beyond the typical temperature control elements provided by other systems like air conditioning, natural ventilation solutions focus on improving occupant health and building efficiency.

The most notable benefits that arise from installing roof ventilators are:

Improved Air Quality

At the same time that fresh air is drawn into a roof cavity via vents, pollutants, odours and other airborne contaminants are removed by natural vent systems. The continuous airflow promoted by careful ventilation design leaves the indoor air quality greatly improved.

Without appropriate ventilation, the build-up of these contaminants can lead to health issues. That is why there are strict requirements around roof vent installation, especially in spaces such as health care.

The main concerns around poor ventilation include:

  1. Failure to prevent the spread of infectious diseases
  2. Exposure to mould
  3. Respiratory issues
  4. Unhealthy levels of carbon dioxide
  5. The development of chronic health conditions like “sick building syndrome”

Reduced Heat Build-up

With a roof ventilation solution working to expel hot air alongside pollutants, the installation of such a system can prevent building occupants from overheating. This is particularly crucial in areas of Australia where excessive sun exposure or humidity may be a concern.

Energy Efficiency

By using a natural solution to reduce heat build-up, you can also save energy consumption and money without the need to continually run air conditioners. This also applies in the colder months, with warm air capable of being circulated through a building through natural vent designs.

Over time, a natural roof ventilation system can greatly reduce your energy costs. Particularly when compared to mechanical ventilation solutions as they require a continuous source of power for operation.

So, you can not only lower your electricity bills with the cost-effective designs of natural vents but also lessen your overall impact on the environment.

Moisture Control

Through the ventilation of hot air, natural roof vent systems also remove excessive amounts of moisture from a building. This is crucial not just for the health of occupants, but also for the integrity of the building itself.

Excessive moisture indoors not only encourages harmful mould to grow, but left unattended it can also begin causing wood rot to eat away at a building. Along with the development of other moisture-related problems, structural damage on the roof and other building materials can add up.

Roof vents are a simple yet effective solution to prevent such damage from occurring. They can also lengthen the lifespan of most roof types, preventing restorative costs from being added to your commercial business.

Step-by-Step Guide to Roof Ventilation Installation

There are some instances where a roof vent product can be installed in a DIY style. For example, some whirlybird vents can be added to simple roof designs, but it should only be done by those with experience in ventilation installation.

However, it is always best to leave the installation process to the roof ventilation experts like Airocle. With over 100 years of ventilation experience in bespoke installations, the team offers a streamlined process for any commercial building:

Step 1: Consultancy

Whether you are looking to improve ventilation in an existing building or integrate an expert design into a future build, it is always best to talk to a roof ventilation specialist.

Beyond an initial consultation, respected ventilation services will be a reliable source of information and guidance throughout an installation project. Even if you choose to handle the physical labour yourself, self-installation support may be available to ensure that the process goes smoothly.

By laying out your building’s design, your occupant’s needs, and the environmental factors that can influence the indoor environment, you can gain expert insight that will aid you throughout the installation.

 

Step 2: Design

Mapping out a natural ventilation system can be more complex than originally thought, especially if it is being integrated into an existing structure. Ensure that your roof vents are installed correctly by collaborating with an expert on the design.
