Roof Turbine Vent Installation Cost Guide

Understanding Roof Turbine Vent Installation Cost for San Diego Homes

Installing roof turbine vents in San Diego can cost between $580-$1,350 depending on the roof type and number of vents. These vents are crucial for reducing attic heat and moisture, extending roof life, and meeting California Title 24 codes. This guide provides a detailed breakdown of costs and considerations for trade professionals.

Why Proper Ventilation Matters

Reduces attic temperatures by up to 40 °F, easing HVAC load
Prevents moisture that leads to mold, warped sheathing, and shingle failure
Extends roof life and can lower energy bills by 10%-15%
Meets California Title 24 ventilation codes

The Four Parts of Roof Turbine Vent Installation Cost

1. Materials

Most projects use 12-inch aluminum or galvanized steel turbines. Material prices in 2025 average $55-$95 per vent for standard units. Specialty colors or stainless steel models run $120-$175 each.

2. Labor

Vent installation requires cutting a hole, installing flashing, seating the turbine, and sealing penetrations. Labor averages:

Single-story asphalt shingle roof: $140-$180 per vent
Two-story or steep-slope tile roof: $190-$260 per vent

3. Permits and Inspection

Permits run $75-$145 depending on municipality, plus a $45-$60 inspection fee.

4. Ancillary Costs

Roof repairs around vent area: $4-$7 per sq. ft.
Extra underlayment or ice-and-water membrane: $1.25-$1.75 per sq. ft.
Removal of obsolete electric attic fans: $50-$90 each
