How to Install Ridge Vent – What Homeowners Should Know

Proper ventilation is essential for any roofing system, especially in North Carolina’s hot and humid climate. One of the most effective ways to ventilate your attic is by installing a ridge vent—but how does it work, and how is it installed?

A ridge vent runs along the peak (ridge) of your roof and allows hot, moist air to escape from the attic. When paired with proper intake ventilation—like soffit vents—it creates a continuous airflow that helps regulate temperature and humidity.

Benefits of ridge vent installation:

• Reduces attic heat, improving energy efficiency
• Prevents moisture buildup and mold growth
• Extends the life of your shingles and roof deck
• Helps maintain manufacturer warranties
• Balances airflow in both summer and winter

How a ridge vent is installed:

1. Cutting the ridge slot: A narrow gap is cut along the roof’s ridge line (usually 1–2 inches wide).
2. Laying the vent: The ridge vent product (usually a breathable plastic or metal strip) is placed over the slot.
3. Securing it: It’s nailed or fastened into place along the ridge.
4. Shingling over: Shingles are installed over the vent to blend with the rest of the roof.
5. Checking intake airflow: The vent works best with adequate soffit vents, so balance is key.

While the process might seem simple, it requires precision and understanding of your roof’s structure. We always recommend having a professional perform the installation to ensure proper airflow and avoid damage.

If your attic is unusually hot, your HVAC struggles to cool upstairs rooms, or you’ve noticed mold or mildew, poor ventilation may be the cause. A ridge vent, combined with balanced intake, can significantly improve the health of your home.

FAQs

Q: How do I know if I already have a ridge vent?
A: Check the peak of your roof. A ridge vent is usually a low-profile strip that runs along the very top, often covered by matching shingles.

Q: Can I install a ridge vent without soffit vents?
A: It’s not recommended. Without intake vents, the airflow won’t circulate properly, and the ridge vent won’t function effectively.

Q: Will installing a ridge vent void my roof warranty?
A: No—as long as it’s installed according to manufacturer guidelines. In fact, proper ventilation is often a requirement for warranty coverage.
