Many assume the roof is only there to keep a home dry. While true to an extent, the roof can't do its job without the proper ventilation. Roof vents installed at the roof's peak offer an unobstructed exit for heat, hot air, moisture, and odors trapped in the attic to escape through. A well-ventilated roof can boost your home's energy efficiency, improve interior comfort, and extend the lifespan of your shingles.

Roof ventilation allows hot attic air to escape, which helps your heating and cooling system run more efficiently. It also prevents moisture buildup, protecting against condensation issues that can damage attic and roofing materials, such as insulation and shingles.
Proper attic ventilation is vital during the winter months, as it keeps ice dams from forming on the roof. Ice dams, which develop when water from melting snow freezes along the roofline, can cause devastating damage to your home. As the ice builds up, water can't drain off the roof properly. Rather than draining into the gutters, it pools on the surface of the roof where it can find its way under shingles and begin leaking into the home.
A properly ventilated roof keeps this from happening by working in tandem with your attic's insulation to keep the roof surface cold. This ensures that snow won't melt on the roof, freeze, and form ice dams along the eaves.
Ridge vents are usually covered by a layer of shingles when installed on an asphalt roof. Warm attic air naturally rises to the roof peak and escapes through the ridge vents.
There are different types of roof vents and strategies for achieving reliable roof ventilation, including:
Ridge vents are commonly installed on the roof peak and are probably the most important vents in any "passive" or non-electric roof ventilation system.
The vents allow hot attic air to rise and escape outside the home. In the photo, the ridge vent openings are the continuous space on each side of the ridge cap.
Soffit vent grilles run parallel to eaves along the soffit. This system works with ridge and gable vents to promote effective roof ventilation. Soffit vents let outside air into the attic so that warm air can exit through higher vents.
Most vents run continuously under eaves. But rectangular or circular vents can be installed in soffits where there is no strip.
A gable-end vent is a screened vent installed near the peak of a gable end. The screen allows hot air to exit the attic and fresh air to enter, depending on the outside breeze and temperature.
If your attic doesn't already have efficient airflow, then a roofer may recommend a gable-end vent.
