During hotter months, high temperatures in the attic can damage roof shingles and materials, leading to the need for roof repair or replacement. The heat in the attic can also put a greater demand on your cooling system. Poor ventilation can also cause mold and mildew in the attic. Roof vents allow heat in the attic to escape.
During winter months, roof vents allow cool air into the attic, which helps keep the roof surface cold and prevents the formation of ice dams. Ice damming occurs when snow melts and refreezes along the home's eaves. Ice dams are a common cause of water damage.
The type of roof vents you need depends on a number of factors. Our roofing professionals can help you choose the best attic ventilation solution. Here are the options:
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.
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.
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.
