Roof Ventilation

Besides furniture and other interior décor aspects, your home needs the right temperatures to ensure comfort. However, you can’t always depend on your AC unit to keep your indoor spaces cool – overdependence on these systems can increase your electricity bills significantly. As a result, more homeowners are installing roof ventilation systems. 

What are Roof Vents, and How Do they Work?

Roof vents are equipment that keeps indoor temperatures at desirable levels by facilitating air exchange. There are different types of roof ventilation, including the dome, gable intake, ridge, soffit, and turbine vents. 

Regardless of design, roof vents work by allowing hot air to escape and let in cool, low-pressure. There are two main methods of creating airflow in your attic; mechanical – where the roof vent uses a power source, and natural, where the wind creates a stack effect that drives the vent. 

Why Should You Install a Roof Vent?

Here are some benefits of installing roof ventilation systems.

Reduces Energy Costs

As mentioned earlier, installing a roof vent is a proven way to reduce energy consumption, saving money. In addition, roof vents keep attic temperatures low. The hot air inside your house rises and escapes through the vents resulting in a cooler, more comfortable feeling inside. 

A roof vent can reduce your dependence on air conditioning units on hot summer days. You’ll need to turn it on for a few hours, lowering your daily energy consumption. Over time, you’ll notice a significant reduction in your monthly electricity bills.

Extends Your Roof’s Lifespan

In regions that experience heavy snowing during winter, it’s common to notice icicles hanging off the roofs of some buildings. This is called ice damming, and it can cause serious damage to your roof.

Ice damming occurs when the heat inside your attic combines with the sun’s heat to melt the snow accumulating on your roof. Due to the low ambient temperatures, the water refreezes before it falls, causing severe damage to your roof, ceiling, walls, and even floors. 

Roof ventilation allows warm air inside the attic to escape before it melts the snow on your roof. As such, you don’t have to worry about icicle damage.

Additionally, roof vents protect roofs from inside-out damage. When it gets too hot in a stuffy attic, the excess heat causes the roofing material to expand. As a result, it can start cracking over time, reducing its lifespan if it’s wooden or metallic.

Also, roof vents prevent moisture and mould damage. In winter, condensation causes problems by cooling hot air as it rises. If your roof doesn’t have ventilation, the cooled air turns into moisture, which dampens your ceiling, roof trusses, and rafters. Over time, it causes mould formation, requiring you to replace the entire roof. 

Even Indoor Temperatures

Have you ever walked into a different room and noticed that it’s warmer or cooler than others? It’s frustrating to live in a house that experiences uneven indoor temperatures. You find it challenging to keep the home comfortable, and you’ll likely spend most of the time by the thermostat trying to find the right balance. The most common reason for these extremes is poor roof ventilation.

You can attain even indoor temperatures by installing proper roof ventilation. The vents will let hot air escape and let in cool air, keeping your home comfortable throughout the year.

How to Assess Your Roof Ventilation

A roof ventilation system isn’t enough – to enjoy the benefits mentioned above, it must be in good condition. The easiest way to evaluate your roof vents is by touching the ceiling on hot days – if it’s hot, you need better ventilation. Similarly, if icicles form during winter, it’s time to renovate or purchase new roof vents. 

Wrapping Up

Roof ventilation might seem unnecessary if you have a functional AC unit. However, it can help you reduce energy bills and guarantee indoor temperatures. More importantly, it prolongs your roof’s lifespan, something you can’t get from an air conditioning system.
