Roof ventilation is often overlooked which makes sense, since most people are simply worried about their roof keeping their home dry. But, a well-ventilated roof can make life easier and better for those living under it. Proper roof and attic ventilation can lower heating and cooling costs, improve interior comfort, and grant longer life to roof shingles.
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.

There are different types of roof vents, and different strategies for achieving effective roof ventilation. Here's a brief overview:
Not always easy to see, the openings for a ridge vent are the continuous space on either side of the ridge cap
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 may run continuously under eaves. Rectangular or circular vents may be installed in soffits where a continuous strip-type vent was omitted.
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.
If attic airflow is insufficient, your roofer may recommend a gable end vent such as the one shown.
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.
Whirlybird vents, also known as turbine vents, are cylindrical domes with fins that spin to create a vacuum which sucks warm air out of the home. There are two main varieties: Active & Passive. Active vents are mechanically driven in order to turn continuously, making a permanent vacuum effect. Passive vents instead rely on natural wind to spin the turbine
Whirlybirds are a popular option thanks to their affordability and they are also easy to install. However, while whirlybirds can be an effective ventilation option on their own, they tend to be most effective when paired with other ventilation options like soffit vents and ridge vents.
If your roof is not well-ventilated, ask a roofing contractor about improving roof ventilation with ridge, soffit or gable-end vents. All of these roof vents can be installed in an existing roof, or when your roofing is being replaced.
