Roof turbine vents are essential parts of your roof! They help to prolong your roof’s life span and provide good ventilation throughout your roof and home. Sufficient roof ventilation is important throughout both hot and cold seasons.

The installation process of your roof turbine vent depends on the design of your roof (flat or sloped). In any case, it’s important to know how a roof turbine vent works before going ahead and attaching one to your roof.

In this article, our professional roofers explain how roof turbine vents work and why everyone should have one on their roof.

How a roof turbine vent works

As its name suggests, a roof turbine vent is key to maintaining good roof ventilation. They are installed with the purpose of circulating air around the roof to avoid unnecessary damage.

By helping to ventilate the roof, roof turbine vents prevent condensation in winter and keep heat out during summer. They also prevent your roof from drying out following heavy rainfall.

Flat roof ventilation

It’s quite simple to facilitate adequate ventilation in a flat roof. Having a flat roof with an attic is the perfect combination for generating good airflow. On a flat roof, the roof turbine vent is installed on top of the slight slope and acts as a ventilation regulator.

The installation of air inlets and outlets by the gutters is also effective in providing good roof ventilation. The turbine vent is installed at the highest point of the roof and ventilation holes are added on the minor slopes to help keep the air flowing.

Sloped roof ventilation

For sloped roofs, ventilation is more complex. This type of roof is more difficult to ventilate because there is no attic.

With these roofs, ventilation is generated by dividing the roof into several sections and placing a turbine vent in the centre of each section. For sufficient ventilation, you should divide your roof into equal parts, such as a 4 square quarters, or for larger roofs, many square zones like a chess board. 

What are the benefits of roof turbine vents?

Having a roof turbine vent is essential. Ventilation systems are highly useful, both in summer and winter. Ideally, your attic should be at the same temperature as the outside.

In summer

During the summer months, roof ventilation will prevent overheating and protect your roof from hot temperatures by pushing the heat outwards. Too much heat in the attic can affect the roof shingles and their stability. Heat that gets trapped in the roof will inevitably get into the house through the ceiling.

In winter

Roof ventilation is equally important during the winter. A poorly ventilated roof will let ice accumulate. As you’re probably already aware, the presence of ice dams on the roof can be particularly harmful. Good ventilation means that you won’t have to worry about de-icing your roof in winter. With a proper ventilation system, you shouldn’t encounter any roof leaks, humidity, or waterproofing issues.
