Ventilation For Your Roofs – Choosing the Right Option

February 26, 2023

Ventilation is mostly overlooked by homeowners. If you desire comfort, a roof is one part of your building that you mustn’t take for granted. Choices are crucial in the roofing of any home, especially in South Carolina. If your house gets too hot or too cold, you are likely using a roof vent. You may also be unsure about what roof vent to use. To get the best advice, consult only experienced residential roofing contractors in Anderson.



Roofing contractors who know their onions will tell you there isn’t any such thing as the best roofing ventilation. Each kind of roofing ventilation has peculiar qualities and will serve best in certain conditions and locations. To make the right choice, you only need to discover what type of roof vents will work best for your building.

This article will show you how roof vents work, the types of roof vents, and the factors that determine the right choice.

What Are Roofing Ventilations?

Roofing ventilation is a roofing system that ensures a healthy and continuous flow of air through the attic of your home. Without being a roofing expert, you will agree that something is wrong with the idea of air-tight roofs. Air loves to move and won’t like to get trapped in any home. Roofing vents provide that freedom. Warm air needs to find a way out of your home to maintain a suitable temperature.

Does Roofing Ventilation Work?

Yes, more than it gets credit for. When experienced and skilled professionals handle the roofing ventilation, it can make a lot of difference in your home. The type of roofing ventilation also plays a key role in providing the level of comfort you desire for your home.

Cold air is heavier than warm air. So, when there is a mixture of both in your house, the warm air rises to the top, leaving colder air below. If your roof has a vent, warm air can easily escape.

During cold months, roof vents will vent moisture from your home and deal with the challenge of ice dams. Apart from natural ventilation, roof vents also utilize solar, wind, and electrical energy to provide an effective passage for air.

Residential Roofing Contractors in Anderson Explain How to Choose a Roof Vent

Roof vents come in different sizes and types. Each of these roof vents will not be suitable for just any roof. There are factors you need to consider to make the best choice of a roof vent. For example, you don’t want the roof vents to be more or less than your building requires.

Your choice of roof vents should depend on your roof’s area or the attic’s size. Therefore, you must consider the area of your roof. For example, your roof requires a square foot of vent for every 300 square feet of attic space.



Also, you will require solar and electrical powered vents for more extreme conditions than you would the natural vent system. Lastly, do you want roof vents that protrude and are conspicuous or those that keep a low profile? Your answer will also guide your choice.

Types of Roof Vents

Many options are available when deciding on your home’s roof vent. Residential roofing contractors in Anderson explain the different types of roof vents below.

  • Ridge Vent

Roofing contractors place ridge vents on the ridge of the roof. Ridge vents run across the entire roof length and aren’t very conspicuous.

  • Wind Turbine Vent

Wind turbine vents are pretty conspicuous and effective. They are also compatible with most types of buildings. The cap of the wind turbine rotates along with the wind direction, releasing hot and humid air while at it.

  • Hip Vent

Hip vents aren’t easy to notice from afar. They are fixed close to the ridge and expel warm air effectively.

  • Power Vent

The power vent relies on electricity. It uses an electric motor and fan to suck hot and humid air out of the home.

  • Box Vent

Box vents are large boxes that are placed over holes in the roofs. These boxes allow hot and humid air to leave the home.

  • Soffit Vent

Soffit vents are intake vents. This means that rather than expel hot air, they allow cool air to enter the house through the roof. Soffit vents lie under the roof’s eaves, extending over the home’s walls.

  • Over Fascia Vent

This vent lies on top of the fascia board. The over fascia vent runs throughout the length of the fascia board and introduces cool air into the home.

Reduced Energy Bills

If your energy bills go up during certain seasons, it is likely due to an increased need for temperature regulation. Roof vents are energy efficient. They will ensure that your home won’t require the heavy use of temperature regulatory appliances. This way, your home stays at a more conducive temperature, and you can save money for other needs.

Preventing Ice Dams

Ice dams are ridges of ice that hang on the edges of your roof. Ice dams prevent more ice from flowing down and falling off your roof. As a result, ice begins to build up on the roof.



Ice dams can weigh many times up to hundreds of pounds, which can damage your rooftop. Also, when the ice build-up melts, they usually produce enough pressure to leak into your home. These water leaks can damage your home’s interior and harm insulation.

Roof ventilation makes your roof unwelcoming to accumulated ice. Roof vents make the attic cooler and uniform with the exterior temperature. Therefore, the attic doesn’t contain warm air to melt snow into the edges of your roof, which prevents dams from forming.

Preventing Moisture Damage

Roofs can suffer heavy moisture damage when roof vents aren’t in place. Molds will also form when warm air from the home’s interior causes condensation during winter. Moisture damage also harms the structural integrity of your roof, leading to more frequent repairs.
