Wind-driven turbine vent $20 – $100 $30 – $160 $50 – $300

*Roofers charge a $150 to $300 minimum service fee.

The following factors affect the cost:

  • Attic size – Larger spaces require more vents, increasing the cost.

  • Roof style – Roofs with multiple peaks may require more than one ridge vent for optimal ventilation.

  • Roof pitch – Working on steep roofs costs more in labor due to the increased difficulty and risk.

  • Existing vents – Roofing experts recommend sealing existing gable vents when installing ridge vents for the best circulation.

  • Electricians charge $50 to $130 per hour to run a new electrical line to the attic for powered roof vents.

  • Roofing contractors charge $30 to $80 per hour for labor to install or replace roof vents.

  • Roof repairs cost $150 to $1,000 for minor repairs and may include sealing leaks, repairing flashing, and replacing shingles or rotten decking.

  • Old vent removal – The cost for removing and disposing of old vents depends on the number and size of vents removed.

  • Permits – New roof vent installation typically requires a permit.

Cost to add ventilation to an attic

Attic fan installation costs $300 to $900 and provides active ventilation from a motorized fan. Adding passive attic ventilation like gable vents costs $150 to $700. Additional intake vents may be required when adding an attic fan.

Cost to install or replace gable vent

Gable vent replacement costs $100 to $500, depending on the material and style. Gable vents act as both intake and exhaust, but they need wind to be effective. Pair gable vents with soffit vents for the best performance.

Soffit vent installation or replacement cost

Soffit vent replacement costs $300 to $650, including labor and materials. Soffit intake vents are installed under the eaves at the lowest part of the roof and are typically paired with ridge or gable exhaust vents.

Roof turbine vent installation cost

Roof turbine vent installation costs $50 to $300, including the vent and labor. Roof turbines or whirlybirds are most beneficial where winds average 5 miles per hour or more. Turbine vents are the only passive vent with moving parts, using the wind and convection to spin the fan.

Powered roof vent cost

Installing a powered roof vent costs $200 to $1,400, depending on the size and whether it is solar-powered or electric. Roof vent fans are installed on the back roof near the top ridge to exhaust warm, rising air from the attic.

Powered roof vents must be paired with intake vents that draw in outside air at the lower part of the roof.

Vented drip edge prices

A vented drip edge costs $3.50 to $7.00 per linear foot with installation. Vented drip edges are ideal for homes with limited or no roof overhang and prevent water from damaging the fascia and roof decking.

Roof vent cap replacement cost

Roof vent cap replacement costs $50 to $230 for parts and labor. The vent cap alone costs $20 to $70, depending on the size and material. A roof vent cap is designed for piped appliances that require outside venting. The cap prevents debris and rodent intrusion without blocking the airflow.

Roof ventilation FAQs

What is a roof vent and how does it work?

A roof vent allows rising hot air to flow out of the home. Roof vents work together with intake vents at the gable or soffit to facilitate airflow through the attic and prevent moisture buildup. Roof ventilation improves energy efficiency for all climates, extending the roof's life by reducing condensation.

Roof vents are active or passive:

  • Active roof vents use motorized fans to expel hot attic air.

  • Passive ventilation uses natural airflow, convection (rising heat), and wind to expel the hot air.

Are ridge vents worth the cost?

Ridge vents are the most cost-effective and energy-saving ventilation type when paired with soffit vents. Ridge vents provide a streamlined look and do not require putting multiple holes in the roof or walls. Some ridge vents come with screens to prevent rodent intrusion.

How many roof vents do I need?

Homes with vapor barriers need 1 square foot of venting per 300 square feet of attic space. Double the venting to 1 square foot per 150 square feet of attic space for homes without a vapor barrier.

Roof vents needed
Home conditions Vent size recommended
With vapor barrier 1 SF per 300 SF of attic space
Without vapor barrier 1 SF per 150 SF of attic space
With attic fan or whole house fan 1 SF per 450 CFM of airflow

  • Ventilation should be an equal, evenly spread combination of intake at the eaves, soffit, or fascia and exhaust at or near the roof ridge.

  • Homes with an attic fan or whole house fan require at least 1 square foot of venting per 450 cubic feet per minute (CFM) of fan airflow.

  • Homes with steep roofs may require more ventilation due to the increased attic size.

  • Most vents have a net free area (NFA) rating. NFA is the amount of available airflow space and is lower than the vent size after adjusting for the area covered by screens and louvers.

Should the ridge vent go all the way across the roof?

Ridge vents should not go all the way across the roof, but a vent cap may be installed at each end to create the seamless appearance of the ridge vent running the entire length of the roof.

What type of roof vents are best?

The best ventilation system uses an equal combination of intake and exhaust vents:

  • Ridge vents paired with soffit intake vents work best for most homes.

  • Ridge vents paired with fascia vents work well for homes with no overhang for soffit vents.

  • Choose box vents when ridge vents are not feasible.

Is an attic fan necessary with ridge vents?

An attic fan is unnecessary and is not recommended with ridge vents. Running an attic fan with ridge vents may prevent heat from rising to the ridge vents and pull rainwater into the attic, causing moisture damage and increasing AC costs.

Who installs soffit and gable vents?
