RIDGE VENTS & ROOF VENTILATION

RIDGE VENTS & ROOF VENTILATION in Greater Vancouver and Portland Area

We Install Soffit, Gable & Ridge Vents for Effective Attic Ventilation

It’s common for people to prioritize a dry roof over ventilation, but proper ventilation can greatly improve life under it. Assured Exteriors understands this and offers expert ridge vent installation and repair services. With well-ventilated roofs, you can enjoy lower energy bills, enhanced interior comfort, and prolonged shingle life.

During summer, ventilation lets hot attic air escape, reducing the strain on your AC. In winter, it works with insulation to prevent snow melting and forming ice dams. Assured Exteriors is here to help with all your ridge vent needs. Contact us at 503-484-0640 or click below for a free estimate in the Vancouver, WA and Portland, OR region.

Add Roof Vents to Ensure a Long-Lasting Roof Over Your Head

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.

The specialists at Assured Exteriors can help you choose the right type of roof vents for your home. We can repair or install roof vents and improve your attic ventilation.

Types of Roof Vents:

Soffit 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 may run continuously under eaves. Rectangular or circular vents may be installed in soffits where a continuous strip-type vent was omitted.

 

Gable-End Vents

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.

 

If attic airflow is insufficient, your roofer may recommend a gable end vent such as the one shown.

 

Powered Attic Ventilators (PAVs)

Often known as attic fans, Powered Attic Ventilators (PAVs) come in various types. Some are roof-mounted, while others are installed in the attic floor or the gable end. PAVs typically feature an electric fan, usually thermostat-controlled, which expels hot air from the attic during hot summer days.

While PAVs can effectively ventilate the attic in hot weather, they may not be necessary if the roof has properly sized and installed ridge and soffit vents. Additionally, PAVs consume electricity and may inadvertently draw cooled air from the living space through attic floor leaks.

 

Many home energy experts recommend passive roof ventilation over active ventilation with a PAV.

 

Ridge Vents

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.

 

Not always easy to see, the openings for a ridge vent are the continuous space on either side of the ridge cap.
