Quick Answer: What Does A Ridge Vent Do

A ridge vent is an air exhaust vent installed on the peak of a roof. Eave and soffit vents, or vents placed where a roof or overhang juts out over the home’s exterior wall, will allow cooler, dry air to enter the lower attic space.

Are ridge vents worth it?

Does my roof need a ridge vent? Yes, If you live in a hot or humid climate a roof ridge vent can lower your cooling bills and lower you attic temperature. While there are many types of roof vents available, many experts agree that ridge vents are the most efficient and cost-effective ventilation system.

What is the advantage of ridge vents?

INCREASE VENTILATION In combination with wind, a ridge vent can create a ventilation system in your attic. It ensures that fresh air circulates continuously, which is critical to preventing mold and mildew from growing in areas like the attic crawl space and the underside of the eaves.

Will ridge vents help cool house?

1. They balance out the temperature of the home. When you have a new home built, or you’re replacing a roof, then installing a ridge vent helps to balance out the transfer of hot and cold air.

Is a ridge vent better than roof vents?

Ridge Vents vs Box Vents. Continuous ridge vents are more effective because they are installed at the peak of a roof’s ridge, allowing for warm air to escape from the attic. It also works better because it creates a vacuum in your attic.

Is a ridge vent enough ventilation?

A ridge vent along with other vents that draw in colder air is enough ventilation. However, a ridge vent alone without some intake vents wouldn’t do as much. We highly recommend installing soffit or gable vents along with a ridge vent or some other form of air intake.

Should ridge vent go all the way across roof?

If you’re wondering whether a ridge vent should go all the way across a roof, it depends. You don’t want to cut ridge vents all the way to the edge, but you can install vent caps all the way to the edge. Ridge vents on metal roofs can be installed in a similar fashion.

Do ridge vents cause leaks?

With proper installation and care, ridge vents should not leak. However, improper installation leads to leaky vents. In some cases, installers will use the wrong nails or shorter nails to secure the vents to the structure. Another problem that can lead to leaking roof ridge vents involves sealant.

Is a ridge vent better than an attic fan?

Ridge vents are much cheaper and more durable than attic fans. They’re more cost and energy-efficient. But they can’t ensure proper ventilation always. Hence, for larger and congested spaces, an attic fan is the best option.

Should I put a ridge vent on my shed?

A ridge vent is indeed necessary on a shed, especially if you live in a hot climate. It works to pull in cooler air from the soffits while venting out hot air that rises and collects from near the roof.

Do you need an attic fan if you have a ridge vent?

Combining an attic power vent fan with a ridge vent is usually not recommended because: It could reverse the natural flow of hot air out the ridge vent. If air is drawn in through the ridge vent while it’s raining, it might pull rainwater in with it, which could lead to leaking or mold in the attic.

What is the best roof ventilation system?

Edmonds’ Windmaster is a go-to ventilator for many homeowners looking for a cost-effective heat exhaust solution. In terms of whirlybirds, the Windmaster is perhaps the most reliable of the lot.

Do ridge vents get clogged?

Ridge vents can easily become clogged as they are filled with dust, mold, mildew, or animals making nests near or in them. Most of the time, it will take several years for your ridge vents to become clogged, with most houses taking several years to get even some clogs.

Can a ridge vent be installed on an existing roof?

An efficient way to gain enough venting area in the roof is by installing ridge vents. Both metal and shingle-over ridge vents are available, according to Lowe’s. The basic procedure for installing them is the same, but you have to cover the latter variety with shingles.

Can an attic have too much ventilation?

It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.

Do you need soffit vents with ridge vents?

Ridge vents can work without soffit vents, however, this won’t be very energy efficient. Without soffit vents, the ridge vents will draw air from some other inlet on the roof like a gable, but this will limit the extent of air circulation in the attic.

How much does a ridge vent cost?

Ridge vents cost $2 to $3 per linear foot. Roof vents come in a variety of styles and range from $10 to $500 each. Ridge models run the length of a roof’s peak and allow warm, moist air to escape.

Can you walk on a ridge vent?

While on the roof, walk along the entire ridge vent and make sure that all of the fasteners are secure and in place. Usually, they should be placed every 18 inches apart. Roofing nails can come loose over time, especially when there are strong guests of wind from heavy storms.

How do ridge vents keep water out?

There are various entry points for moisture in your roof; rain can enter your roof through any of these. One potential entry point is the ridge vent. Ridge vents prevent moisture problems by letting warm air out, but wind-blown rain can enter if the vents are damaged.

Can rain get in roof vents?

But some roof air vents sit fairly flat to the roof, with a mushroom style hood and unprotected sides. And on occasion a hard driving rain with whipping wind will cause roof vents to leak water. If your roof vent leaks during heavy rain, the rain may be blowing up under the hood and into the vent.

How does a ridge vent work on a house?

A ridge vent is an air exhaust vent installed on the peak of a roof. When installing this vent, an air slot is first cut in the roof deck at the roof’s peak. As the air in the attic heats up, convection helps push the air to the peak of the roof where it escapes through the ridge vent.

Do ridge vents work when covered with snow?

Ridge vents with external baffles are not only better at keeping clear of snow (drawing right) but they are also more efficient at exhausting air from the roof cavity. Like any ridge-venting system, baffled vents should be used in combination with continuous soffit vents.
