How to Install Kitchen Exhaust Vent Through Roof

Ridge models run the length of a roof's peak and allow warm, moist air to escape. Soffit vents run along the underside of eaves and enhance airflow by allowing it to enter from outside. Roof and gable versions provide a single point of exit and entry for air. The best system is a combination of ridge and soffit units. However, any airflow is better than none.

Average Roof Ridge Vent Costs

Average Cost	$475
High Cost	$650
Low Cost	$300

Ridge Vent Cost Per Foot

Expect to pay $2 to $3 per foot for ridge venting, not including installation. They sell in four-foot sections for $8 to $12 per section. The average home with a peaked roof will require 40 to 50 feet of material for a total cost of $80 to $150. You will also need connector plugs and straps at $5 to $6 each to adjoin pieces. Estimate $10 to $15 per 5-pounds bag of roofing nails and $20 to $30 per 200 to 300 specialty roofing screws with neoprene washers that create a seal. Homes with flat roofs or other designs without ridges will require another type of ventilation.

**Average Costs to Install Ridge Vents**
Line Item	Cost
Vent	$2 - $3 per foot
Vent for average home (40 to 50 feet)	$80 - $150
Additional Materials	$35 - $50
Professional Installation	$45 - $75 per hour
Average Project Total	$400 - $500

Ridge Vent Installation Cost

Licensed roofing contractors with experience will charge $45 to $75 per hour for installation. Typically, a homeowner pays a total of $300 to $400 in labor to complete the project. Exact figures will depend on the scope and difficulty of the job. Projects that need additional repairs, need old units removed, or have accessibility issues will take longer and cost more.

Replacing Roof Ridge Vents

Replacement averages about $500. The project can run as little as $300 to replace a section or two, including the cost to install or replace shingles. On the other hand, complete replacement can be as much as $1,200 if you have a metal roof or if there is accompanying roof damage. Professionals will typically provide an inspection and quote that includes all labor, material, and disposal fees.

Repair Costs

Simple repairs, like replacing fasteners, shingles, or end caps, will run $200 to $300. However, professionals usually recommend replacing roof ridge units instead of repairing them, since unseen damage can lead to poor airflow or even leaking. Most often, the cost of roof repairs will be mostly labor.

Costs to Install Roof Vents

The term "roof vent" can refer to any number of styles, which can cost anywhere from $10 to $500, not including installation. They come in different colors and types, including round ones that look like mesh and larger, rectangular models. Finish color and style will determine exact price. Static units will fall on the lower end of the price range, while powered models will fall on the higher end.

Installation will vary by style and type as well.

A pro can install a static or wind-driven unit in one to two hours at a rate of $45 to $75 per hour, for a total cost of $45 to $150.
A powered model may require three to four hours for between $135 to $300, since the pro must connect it to a power source. Appliance vent installation times and rates vary.

**Vent Cost by Type**
Type	Unit Price	Labort	Total
Mushroom (Static)	$10 - $80	$45 - $150	$55 - $230
Eyebrow/Dormer (Static)	$30 - $40	$45 - $150	$75 - $190
Turtle/Flat* (Static)	$10 - $40	$45 - $150	$55 - $190
Cupola (Static)	$100 - $400	$45 - $150	$145 - $550
Wind-Driven Turbine	$20-$100	$45-$150	$65-$250

Solar Powered	$200 - $500	$135 - $300	$335 - $800

*Also called Low Profile, Box or Louvers. Many home appliances also must push air through the roof. Bathroom exhaust fans, kitchen/range hood fans, clothes dryers, and gas furnaces typically push air to a static or powered unit. Garages may also require a vent to help keep air flowing and prevent mold and mildew.

Roof Turbine Installation

Expect to pay $65 to $250 to install a roof turbine, including labor and materials. Units are priced $20 to $100 each. A pro can install one in an hour or two at a rate of $45 to $75, for a labor total of $45 to $150.

Contractors typically include other materials, like sealant or shingles, in their hourly rate. Turbines are quick to install because while they do contain a moving fan, they do not need to be connected to a power source.

Attic Fan Ventilation

Cost to install an attic fan averages about $560 nationwide. In mild areas of the country where overnight temperatures are cool enough, homeowners may install an attic fan along with their vents. Ventilation fans, also called powered attic ventilators, work from inside the structure to push out hot air and pull in cooler air from the outside.

Powered Roof Ventilators

Powered models range from $100 to $500 per unit and $135 to $300 to install, for a total investment of $235 to $800. Higher-end units with thermostats and humidistats will fall at the higher end of the price range, as will solar-powered units.

Because these operate so quietly, homeowners may not notice when they stop working. To prevent long-term damage, have units inspected every six months..

Roof Vent Replacement Cost

Expect to pay between $150 and $250 for the labor to remove the old unit and secure the new one in place. Of course, you'll also need to purchase a new unit at a replacement rate of $10 to $500.

Repairs

Minor repairs, like reattaching a vent, will cost at least $45 to $150, because most pros charge a one-to-two-hour minimum per job at a rate of $45 to $75 per hour. If the unit itself has been damaged, most pros suggest replacement over repair. (See replacement prices above.)

In some cases, powered models come with a warranty that covers repair or replacement by a licensed professional. On top of repairing damage, you should plan for the cost to clean vents regularly.

Cost to Install Soffit Vents

Installation typically costs a homeowner between $315 and $465. Traditional units range in price from $3.30 to $4.50 per linear foot. Continuous soffit models are single units that run the length of your eaves and average $8 to $10 per linear foot. Prices listed include installation into an existing soffit and do not include the cost to install soffits.

To replace soffit units, you'll pay a roofing pro $45 to $75 per hour for labor, as well as the replacement cost of the materials. Soffit units can increase the efficiency of ridge and roof units by allowing outside air to enter at the lowest point.

Gable Vent Replacement Cost

The replacement price of a gable vent averages between $10 and $60 but can be up to $150, depending on the style you choose. The price of a carpenter to replace or install a gable-mounted unit is about $70 an hour.

Because gable units are visible and can impact the curb appeal of a home, some homeowners choose a more decorative version. Regardless of style or finish, all function the same. In some climates, homeowners may choose to attach an attic fan to their gable unit to help cool the attic air as well as keep it moving.

Roof Ventilation Options - Pros, Cons, & Differences

A quick overview of the different types of models reveals the pros and cons of each.

Ridge

Ridge roof ventilation units are the most effective passive model, barely leaks and works best paired with soffit units. It also blends in with the roof and could actually outlast the roof itself. On the other hand, the shingles may not match when installed later and it's more expensive to repair or replace.

Materials: $2-$3/foot
Labor: $45-$75/hour
Total: $380-$550

Roof

This ventilation option costs less than other options, doesn't require new shingles and is easier to add to an existing roof. On the con side, there's only one point of entry or exit for air flow, usually comes in more unattractive options, and requires inspection every six months.

Materials: $10-500/unit
Labor: $45-$75/hour
Total: $55-800

Soffit

Soffit ventilation units improve ridge, roof and gable vent efficiency and can only be seen from below.

Materials: $2-$10/linear foot
Labor: $45-$75/hour
Total: $315-$465

Gable

Gable ventilation units are the cheapest option, aesthetically pleasing, and can mount to an attic fan, but they also have a single point of entry/exit for air flow.

Materials: $10-$150/unit
Labor: Approx. $70/hour
Total: $80-290

How Do You Calculate How Much Venting You Need?

You should have at least one square foot of ventilation for every 150 square feet of attic space. When possible, you should place half of the units near the top of the structure and half in the soffit at the bottom.

DIY vs. Hiring a Pro

Due to the expertise required and danger of roof work, it is usually best to leave roof vent installation to the professionals.

Using a licensed, experienced pro can prevent pricey repairs or damage from improper installation. The best time to install new ridge and roof units is during roof installation or replacement when you can fold the costs into the existing work. The best time to install appliance vents is when you pay to have the appliance installed.
