Vent Check #1: Look at Your Roof to Find Vents
The first step is to take a look at your roof and see if you can spot any vents. You should also look beneath your roof line; there are often vents facing out that are easily visible. Vents are also usually located near the peak of your roof, and they come in all shapes and sizes. The most common types of vents are visible from the ground. If you see vents that are blocked or damaged, there’s a good chance that they’re not working properly.
Vent Check #2: Touch Your Ceiling
The next step is to go inside your home and touch your ceiling. If it’s warm to the touch, that’s a sign that hot air is seeping into your living space. This is an indication that your roof isn’t ventilated properly and that your attic isn’t getting the airflow it needs.
Vent Check #3: Go Into Your Attic During Winter
Another way to tell if your roof is properly ventilated is to go into your attic during winter. If it’s cold in your attic, that’s a good sign. But if it’s warm, that means hot air is seeping in from your living space below. This can cause ice dams to form on your roof.
Vent Check #4: Watch for Ice Dams
As we mentioned, one of the signs of improper roof ventilation is ice dams. If you see icicles hanging from your roof, that’s a surefire sign that you have an ice dam. But even if you don’t see any icicles, you should still be on the lookout for ice dams. If you see a line of ice along the edge of your roof, it’s a good indication that an ice dam has formed.
Vent Check #5: Check Your Energy Bills
One of the best ways to tell if your roof is properly ventilated is to check your energy bills. If you see a big spike in your energy usage during the summer and winter months, it’s a good indication that hot air is seeping into your home. This can be caused by improper roof ventilation.
Where Should Your Roof Vents Be Located?
There are a few different places where roofers install vents, but you can usually find them near a roof’s peak. You should also see them in the eaves (though some roof vent types don’t need vents in the eaves). Most commonly, you’ll see several sets of vents on your roof.
Types of Roof Vents
- Powered attic ventilators (PAVs).
- Ridge vents
- Soffit vents
- Gable-end vents
- Box Vents
- Off-Ridge Vents
- Cupola Vents
- Power Vents
- Wind Turbines
Sometimes referred to as attic fans, PAVs come in several forms. Some are designed to be mounted on the roof, while others mount in the attic floor or the gable end. All PAVs contain an electrically powered fan (usually controlled by a thermostat) that exhausts hot air from the attic on hot summer days.
A PAV should not be necessary if a roof has properly sized and installed ridge and soffit vents. While a PAV will definitely exhaust hot air from the attic during hot weather, it consumes electricity, and can actually suck cooled air from the living space through leaks in the attic floor.
For this reason, many home energy experts recommend passive roof ventilation over active ventilation with a PAV.
Installed along the roof peak, ridge vents are probably the most important vents in any “passive” (non-electric) roof ventilation system. Hot air that accumulates inside the attic rises by convection and escapes outside through ridge vents.
As hot air escapes, fresh outside air is drawn into the attic through soffit vents (see below).
On an asphalt shingle roof, ridge vents are usually covered by a layer of shingles. The warmest air in the attic rises naturally to the roof peak and escapes outside through the ridge vents.
Soffit vents run parallel to the eaves along the soffit. These vents work with ridge and gable vents to promote good roof ventilation.
Installed along the eaves of the roof, these vents are usually in the form of grilles that run the length of each soffit.
By admitting outside air into the attic as warmer air leaves the attic through higher vents, soffit vents play a major role in effective roof ventilation.
Soffit vents are installed on the underside of the eaves. They’re usually made of metal or plastic, and they have a series of small holes that allow air to flow through.
Installed near the peak of a gable end, this screened vent can allow hot air to leave the attic or fresh air to enter, depending on prevailing breezes and temperature conditions.
Box vents are the most common type of roof vent. They’re installed on the roof, and they have a boxy shape. They’re typically made of metal or plastic, and they have a hole in the center that allows air to flow through.
Off-ridge vents are installed near the top of the roof, but they’re not at the very peak. They’re typically made of metal or plastic, and they have a hole in the center that allows air to flow through.
Cupola vents are installed on the roof, and they have a cup-shaped top. They’re typically made of metal or wood, and they have a hole in the center that allows air to flow through.
Power vents are electric vents that are installed on the roof. They’re typically made of metal or plastic, and they have a hole in the center that allows air to flow through.
Wind turbines are vents that are powered by the wind. They’re usually made of metal or plastic, and they have a blades that turn when the wind blows.

It’s understandable that roof ventilation is often overlooked, as most people are simply worried about their roof keeping their home dry. However, a well-ventilated roof can make life easier and better for those living beneath it. Proper roof and attic ventilation can lower heating and cooling costs, improve interior comfort, and grant
In the summertime, a properly ventilated roof allows hot air in the attic to escape, reducing the demand on your air conditioning system. In the winter, ventilation combines with good attic insulation to keep the roof surface cold, so that snow won’t melt on the roof surface and then freeze to form ice dams along the eaves.
