Sure, it’s nice to keep the rain off your back, but your roof actually does more than just protect you from the weather. Rooftop ventilation systems help circulate air in your home and vent exhaust from your heating units, keeping the air quality in your home safe and healthy.
While not every roof needs a ridge vent per se, your roofer might recommend installing one when you have a new roof put on, especially if you have an older home with gable vents. Many contractors feel that gable vents just aren’t a particularly effective ventilation system—and so they’ll often recommend supplementing them with a ridge vent system, which, as you might have guessed from its name, runs across the ridge of your roof.
But when you’re springing for a new roof, being told that you need to add on another expense might set your teeth a little on edge. After all, you’re already forking over several thousand dollars for a set of new shingles and all the trimmings. How much more do you really need to spend?
Typically, not all that much. Roof vent systems are fairly affordable, especially compared to the cost to reroof. All in all, they should only add a couple of hundred dollars to your project. Here’s how it all breaks down—and what you need to know about costs before you install a ridge vent on your home.
Most Roofers Add Ridge Vents During Existing Roofing Projects
The vast majority of homeowners aren’t out browsing around for new ventilation systems, so the issue of adding a ridge vent to their roof typically comes up when the roofer comes out for another issue—usually when they’re installing a new roof.
If that’s the case, the contractor will roll the ridge vent into the charges for the existing reroof project, which means they may even give you a bit of deal, since you’re already buying a new roof from them anyway. At the very least, you’ll definitely save on labor if you have both parts installed together.
The Average Cost to Have a Roof Vent Installed Separately
However, maybe you need the roof vent installed without touching the rest of the roof. In this case, the job will run you somewhere between $400 to $500. Materials cost between $100 to $125, and the rest of the price is for the labor. Therefore, if you have a very labor-intensive project or if there are complications such as additional repairs or demolition that need to be included in your project, it can ramp up the overall price.
Keep in mind, too, that prices may vary according to your location—for instance, a roofing company in Tampa Bay, Florida may charge more or less than one in Fargo, North Dakota just based on the market values in those areas.
What Factors Can Affect the Cost of Ridge Vent Installation?
It’s easy to quote numbers for the ideal ridge vent installation, but in the real world, there are plenty of factors that can affect the total cost. One of these is the length of your roof—roofers will obviously need to spend more on materials for an exceptionally long ridge. Additionally, some roof styles contain multiple elevations, meaning there are actually two ridges that need to be vented. Both of these situations can drive up the cost of your installation slightly.
Additionally, if you have gable vents, your roofer may recommend blocking them to promote circulation. That process may also add a minuscule amount to your final total.
Other things that can slightly swell that $400 to $500 estimate? If your roofer is tearing off an existing ridge vent, and needs to replace the first course of shingles after pulling off the vent. Or if you have a very steep roof that isn’t walkable, your roofer may charge more to get the work done.
Furthermore, if your roofer gets on top of your roof and notices something that calls for an immediate repair, that can significantly drive up the cost. For instance, your roofer might notice damaged shingles or springy decking (a sign of rot), and so, may suggest that you make additional repairs sooner rather than later. While that’s obviously not something any homeowner wants to hear, you’ll thank yourself later if you follow your roofer’s advice and get it handled before it becomes a significant problem. A leak or a collapse is a truly unpleasant ordeal that no homeowner should have to go through.
Additionally, many roofing companies understand that you haven’t budgeted for these kinds of surprises, and may be willing to negotiate financing or payment plans to cover the cost or repairs.
