Proper Attic Ventilation: Everything You Need to Know About Roof Vents

Homeowners across the United States spent $394 billion on home repair projects in 2018 alone. 

Among the most popular home improvement projects from homeowners is roofing work which among others includes repairing or completely replacing the vents. Since roofing vents directly impact the indoor air quality of your home, you can’t skimp on them or let them become dilapidated. 

To keep your roof in good operational order, here is a deep dive into the importance of roofing vents and the various types of roof vents you can consider using. 

The Importance of Roofing Vents 

Roofing vents perform a critical task in keeping your home running while also protecting your health. Here are some tangible benefits that roofing vents bring to your home. 

1. Controlling the Moisture

Once the air in the attic stagnates, moisture will condense and settle on the insulation and framing. Such a situation encourages rot and mold to take root and is an essential indicator of a bad roof

When mold takes root, it ultimately makes the insulation clump while the rot can cause the roof to sag due to poor framing and decking. Using roofing vents helps ensure that moisture won’t condense and collect. 

2. Temperature Control

When air does not circulate well in the attic, it can cause the air in it to be superheated. Without any air movement, the air in the attic begins to heat up as the sun beats down on the roof. 

The accumulating heat then begins to move through the attics’ floor to the other rooms. The result is that the air in the rest of the house starts to heat up, which drives up your air conditioning use and their resulting energy bills. When you vent your roof, then you can avoid superheating your interior air. 

3. More Roof Shingle Wear and Tear

It’s not only your energy bills that are affected by superheated air, but your shingles also take a hit. Once the air in the attic superheats, it does not only seep out into the other rooms in the house. It also transfers back to the roof as well. 

Consequently, the roof shingles begin to absorb the heat. In the end, the near-constant state of being overheated can reduce the lifespan of your roof shingles considerably and thus durability should be a factor to consider among others as you buy roof shingles. 

Various Kinds of Roof Vents

Ever looked across the different types of roofing vents in your neighborhood and realized that they vary in style and position? That’s because there is a wide variety of roofing vents in use today. Let’s take a closer look at some of these vents. 

1. Soffit Vents

A soffit is that part of your roof that hangs out over the edge and which is hard for you to see. Soffit vents are specifically designed to be resistant to battering by the weather and the resulting wear and tear it causes. They are also designed to be highly resistant to pests.

Soffit vents are destined to take in air. That feature, in turn, can then help your roofing system balance the temperature of the air on the inside with that on the outside. 

It is common to find a soffit vent on a roofing system that uses ridge vents. That’s because ridge vents will sit much higher up the roof which allows the hot air that the soffit vent accounts for. 

2. Turbine Vents

Turbine vents are metallic turbines that are dome-shaped, and which rotate as the wind catches them. The dome-shape of the turbines enables them to pull hot air up and out of the attic much faster than non-moving vents. 

As long as you locate turbine vents in windy areas, then they can be quite useful. The downside of using such vents, though, is that they cost considerably more than static ones and can be less aesthetically appealing. 

3. Box Vents

A box vent (also known as a low profile vent) is little more than an opening which is covered by a box or dome-shaped top. These vents are typically installed along the ridge of your roof (and as high up as possible) with the express aim of letting the heat rise through them and escape via natural convection. 

While box vents are more aesthetically pleasing than turbines vents, they are also more prone to the weather. Thus, when you are looking for roofing contractors, you should inquire if they have experience in setting up weatherproofed box vents. 

4. Ridge Vents

A ridge vent is a space under the roof’s ridge where air from the attic below can escape through. These vets are quite popular due to their easy-to-install nature as part of the original roof ridge. Ridge vents are combined with a good intake vent to push hot air up and out of the structure. 

There is a particular type of ridge vent known as ‘shingle over’ because they are constructed directly under the shingles themselves. Non-shingle-over ridge vents are labelled as such since they are designed as a separate piece of material that is placed on top of the shingle, like a cap. 

5. Powered Vents

Powered vents are different from the other roofing vent types as they rely on electricity to keep the attic cool by quickly moving air out of it. Due to their powered nature, these vents are quite customizable, and that offers you a degree of flexibility that is hard to find with non-powered vents.

Many of the units (especially the earlier ones) work by being wired into your home’s electrical system. However, solar-powered roofing vents are also getting into the market and attracting the attention of homeowners due to their cost-effective nature. 

If your home has poor ventilation or air conditioning, then you may want to reconsider using powered vents. That’s because they may end up being too efficient and pulling heat from the attic rather quickly, making it hard to maintain the ideal cool temperature in your house.
