A ridge vent is an exhaust vent installed along the peak of your roof to release trapped hot air from the attic.
A ridge vent is an exhaust vent installed along the peak of your roof to release trapped hot air from the attic.
It’s a key part of a balanced roofing system for Merrimack County homes. Professionally installed soffit vents below to keep air circulating year-round, helping to lower energy bills and keep your home comfortable.
What NH Homeowners Need to Know About Roof Vents
- Exhaust function: Ridge vents sit at the roof’s peak and push warm, moist air out of the attic. GAF’s Cobra® Ridge Vent is a trusted product designed specifically for this exhaust role.
- Intake partnership: Ridge vents only work well when paired with intake vents at the soffits. GAF’s MasterFlow® Intake Soffit Vents work alongside ridge vents to keep airflow balanced.
- Moisture control: Proper ventilation reduces condensation in the attic, which helps prevent mold growth. It also keeps your insulation performing the way it should year-round.
- Winter roofing tips: In cold climates, good attic ventilation lowers attic temperatures, which reduces the snow melt cycle that creates ice dams. Ice dam removal alone can cost up to $4,000.
- Energy savings: Warm air venting out through the ridge allows cooler air to replace it continuously. According to GAF, this process also helps regulate temperatures and protects your insulation’s condition.
- Inspection timing: GAF recommends inspecting your roof at least twice a year, in spring and fall. A Capital Region roofing contractor can check vent performance during those visits.
| Vent Type | Role | Location | Best For |
| Ridge Vent | Exhaust | Roof peak | All sloped roofs |
| Soffit Vent | Intake | Eaves/soffits | Paired with ridge vents |
| Box/Turtle Vent | Exhaust | Roof field | Older homes without ridge |
| Power Vent | Active exhaust | Roof field | High heat or humidity situations |
Choosing the Right Setup for Your Home
Top Pick: A ridge vent paired with soffit intake vents for homes in the Concord area — this combination delivers the most balanced, year-round airflow.
Worth Considering: Box vents for older homes where a full ridge vent installation isn’t practical, though performance is more limited.
Skip if possible: Relying on a single vent type alone — an unbalanced system won’t move enough air to protect your attic from moisture or heat buildup.
