A ridge vent costs between $300 and $650 on average, with most people paying about $500. Your final costs will vary based on the size, type, and number of units you install. A local professional will be able to give you more accurate information in terms of pricing.
The truth is, most experts agree that though other roof vents allow some ventilation (which is better than none), ridge vents are the most efficient and cost-effective roof ventilation system around. Our recommendation is yes. Especially if you are installing a new roof, you want to extend its life as long as possible.
Don't worry, you won't have to replace the entire roof deck to install a new roof ridge vent. The old method for installing ridge vents was to use the aluminum ridge vent or just aluminum strips, however, nowadays the preferred method is a shingle over ridge vent system.
For a home with 2000 square feet of attic floor space, you'll first divide 2000 by 300 (2000 ÷ 300 = 6.66). You need 6.66 square feet of attic ventilation. Since you want a balanced system, you divide by 2 so that half of the ventilation is intake and half is exhaust.
Cost to Install a Roof Vent
Regarding labor costs, most professionals charge between $45 to $75 per hour for installing a roof vent. It takes approximately one to four hours to complete the installation, depending on the type of vent you have and your roof type.
The average roof ridge vent installation cost is $300 to $650, including labor and materials. While it is a pricier option than some of the others, you are treating yourself to the most effective non-powered roof ventilation system. It also blends in with your roof for a much sleeker look than other vents.
Wondering who installs roof vents? While you may be tempted to do it yourself, the safest way to go is to hire a local roofing company to do the job. Roofers have the training, licensing, and experience needed to install a ventilation system on your roof, without putting you at risk of leaks.
While ridge vents have many advantages, they are not always ideal. In cold climates, ridge vents can allow snow into the attic. They're also more expensive than box vents and won't work on all types of roofs.
Today, most experts (and our team at Rhoden Roofing agrees), ridge vents are superior products to box vents. However, as they are more expensive to install than box vents, they still are not the vest fit for every situation. There is also more variety in the types of ridge vents.
A ridge cap is also a type of baffle used for ridge vents. A cap sits on the ridge vent itself and creates an overlapping shield to prevent water from getting in. Ridge caps also create the vent system pull that sucks fresh air into the attic or roof space and expels stale air.
On average, homeowners can expect to pay between $500 and $1500 for ridge cap replacement. Here's a breakdown of the cost considerations: Material Costs: The cost of materials, such as asphalt shingles, metal panels, or clay tiles, accounts for a significant portion of the overall expense.
While each type—metal, hard plastic shingle-over, and soft foam shingle-over—has its merits, the hard plastic 4-foot shingle-over ridge vent stands out for its unparalleled air exhaust capabilities, making it an excellent choice for homeowners seeking optimal ventilation performance.
Cons of Ridge Vents: Installation: Ridge vents must be installed properly to function effectively. Incorrect installation can lead to leaks and reduced ventilation efficiency. Requires Soffit Vents: Ridge vents rely on soffit vents to draw cool air into the attic.
If you had to choose just one—and your attic has a great need for ventilation—an attic fan is your best bet. Attic fans in the $300 to $400 range can move upwards of 5,000 CFM. For lower capacity ventilation at a steep cost savings, a ridge vent might be your best choice.
“Metal vents — can be susceptible to bent flanges and denting from shipping and handling. Plastic vents are a lot lighter and much more durable.” Donna Burtch, Duraflo® Product Manager at Canplas. Unlike metal roof vents, Duraflo® products do not collect as much condensation with temperature changes.
Unlike most other roof vents, the amount of ridge vent is calculated per linear foot. The standard ridge vent without a baffle is 4 feet long and covers 72 square inches of net free area. With that in mind, you'll need a total of 20' of ridge vent to ventilate a 1,500 square foot attic properly.
Cost: Ridge vents are fairly expensive compared to other ventilation systems – while ridge vents cost around $300-$650 to install, other systems such as gable roof vents cost only between $60-$150 per unit.
Exhaust vents are best positioned near the ridge or peak of the roof, where hot air can easily escape. This placement leverages the natural flow of hot air rising to create a continuous airflow, which reduces the workload on cooling systems and improves energy efficiency.
Look Out for Flashing
In this case, rain can enter your roof through the vents. As for damage to the vents themselves, old age is a factor. Eventually, certain areas of your roof may be worn down, including the flashing that supports ridge vents. You will likely be unable to predict when your flashing is going to fail.
The average lifespan of a roof vent is about 10-20 years, but the lifespan of your roof vent will depend on a variety of factors. Some factors that will affect the lifespan of your roof vent include the type of roof vent, the material your roof vent is made from, and the care your roof vent receives.
Installation Process
Remove enough shingle caps and shingles on the roof's peak to expose at least 3 inches of roof decking. Cut an opening for ventilation in the decking along the peak. Reattach the existing type of roof shingles to cover the exposed deck, adding new high-quality roofing shingles as necessary.
If you're roof-savvy enough to do it yourself, you might want to give it a shot! Roof vents are fairly simple to install, and the job can be completed within a few hours in most cases.
Attic fans range differently depending on what kind of the Attic fan you are installing, you can expect to pay between $350 to $1,000 installed.
