The roof ventilation plays a crucial role in every Branford CT home. If you’ll notice ridge caps peeking through the roof, it’s probably a roof vent. Roof vents are instrumental in keeping a balanced air flow within your attic to regulate the temperature as needed. For those who aren’t aware, these vents come in different sizes and shapes. How will you know which one is the right fit for your property?

What’s the Importance of Roof Ventilation?

Do you really have to care about roof ventilation? What does it concern you as a homeowner? First and foremost, you cannot disregard proper roof ventilation. For one, it’s responsible for prolonging roof and attic lifespan. And besides, the lack of ventilation can lead to many negative implications.

Here are some of the expected results of a poor roof and attic ventilation:

Higher Energy Bill

Improper roof ventilation deliberately traps heat in the attic. If there’s temperature imbalance or if it becomes too hot inside your property, the tendency is to consume more energy supply from excessive use of cooling appliances. The longer you use air conditioning units, the higher the electricity bills would go up. This particular issue is also harmful to the environment in the long run as you contribute more to carbon emission.

Water Damages

If you’re wondering where these recurring attic and ceiling leaks are coming from, you might have to check on your roof ventilation. Poor ventilation cannot prevent moisture penetration. As there’s not enough air circulation, moisture can linger on and then worsen. Soon enough, it will eventually lead to different water damages like leakage. Before you even know it, the problem has spread down to the ceiling and walls.

Growth of Molds

Water damage caused by molds

Moisture in the attic allows molds and mildew to proliferate causing serious damages to the property.

This problem is in connection to the previous point. Improper ventilation allows moisture to proliferate in areas that should be dry all the time. Moist and damp areas are the best breeding ground for plants like fungi, mildew, molds, etc. If you think that it’s okay to keep molds at home, you are mistaken because there are health risks. Aside from the damage that they cause to the areas where they cling on, it can also release harmful toxins to the air. Some reports confirm that these can cause severe allergies, asthma, and other respiratory-related illnesses.

Blocked Drainage System

You might be wondering how this is possible since we’re just talking about the roof ventilation. It’s true that poor ventilation could reach your gutter and downspouts causing trouble with the drainage system. The heat that should be released regularly is trapped inside the attic. It will then melt the snow during winter. When it flows down the gutters, it can potentially refreeze blocking the whole pathway. If this isn’t treated the right way, it will also lead to other issues like sagging gutters, water damages, etc.

Ice Dam Build-Up

Poor roof ventilation can also cause an unwanted build-up of ice dams. When the heat melts the snow above your roof, they will refreeze and turn into what we can ice dams. They may be pretty to look at for a while but sooner it will cause serious damages. These solid crystal-like ice formations can create permanent damage to the roof shingles and the foundation. It can also lead to water damages such as leaks and stains.

Finding the Best Roof Ventilation Options for Your Home

Let us now move on to what roof ventilation options should you consider for your home (so that you wouldn’t have to suffer from the negative outcomes of poor ventilation).

Knowing the purpose of roof vents empowers you to find out the options you have. As a homeowner, you have the right to choose for your property along with the supervision of an expert, of course.

To build a more long-lasting roof for your home, here are some roof ventilation options that you can check out…

Box Vents

These are static types of vents that do not have any moving parts. You can choose from a wide array of color selections. In terms of the material, you can select between hard plastic or metal. Box vents are normally places close to the roof ridge to release the maximum amount of heat and moisture. For larger properties, roofing contractors may recommend installing more than one box vent. Some people also call them flat or turtle vents.

Off-Ridge Vents

Off-ridge vents function similar to box vents. The only difference is their shape. These types of roof ventilation options are usually longer and thinner. For maximum ventilation, you need to install more than one unit.

Wind Turbines

Wind turbines use natural wind flow to effectively function as a ventilator.

Unlike box vents, wind turbines or whirlybirds have moving parts. However, they aren’t powered by motors. Instead, they use natural wind to drive the motion. Since they have turbines running, they can release more air depending on the wind intensity. The spinning action that the turbines create is the one responsible for drawing out hot hair which also regulates the heat inside the property.

In choosing a wind turbine, be mindful of the quality. Less expensive options may produce an unpleasant squeaking sound that could be bothersome.

Power Vents

Power Attic Vents or PAVs run through their built-in electric-powered motors. These motors drive the movement of their huge fans (which release hot air and moisture outside). Some PAVs do have adjustable thermostats which you can set on a specific temperature. Once the attic reaches that level, it will then prompt the vents to run and regulate the air flow. As a more high-end option, you can also find PAVs that have humidistat which could detect humidity levels and automatically turn on as needed. There are variations as well in terms of color selection.

Since PAVs have different components, they need electricity to function. However, some are connected to solar panels for a more energy-efficient alternative. Unlike wind turbines, PAVs are preferred by most families because they run quietly although make sure to inspect them regularly to make sure that they are still in good condition. Their issues might go unnoticed because they function as if they aren’t any ventilators around.

Ridge Vents

Ridge vents are also static as there are no moving parts. They look like a shallow tent facing down the roof. Normally, they are positioned at the roofline adding to the roof’s overall design.

Due to a ridge vent’s tent-like shape, it can distribute airflow more evenly. This gives the roof and attic parts equal opportunities for temperature regulation, unlike vents that are only concentrated on certain areas.

Cupola Vents

This is an example of a wood cupola attached to a metal roof. While it can release minimal heat, it isn’t enough to create a functional ventilation system.

These are decorative types of vents with the main purpose of beautifying the roof. On the other hand, it can also help release hot air but couldn’t do it on their own. They need support from other ventilation systems in order to make them functional enough.

Soffit Vents

Soffit vents are made from PVC or aluminum. They support the roof’s main ventilation system as they help increase airflow. These are usually installed in the soffits and eaves.


There are different roof ventilation options out there but which of them is the right one for you?

To be honest, you don’t have to worry about finding the best one or the ultimate roof vent because each of them has their own qualities and functionalities. It is considered the best if it has the ability to present an effective and functional roof ventilation system.
