Roof Ridge Vent Pros and Cons

There are a number of roof ridge vent pros and cons that come along with them. Just like any other style roof ventilation system, they have their advantages and their downfalls. If you want to be absolutely positive that you are choosing the best roof ventilation system for your home, it’s always better to get a professional roofing contractor to inspect your home and recommend the best option for you. 


Here are some roof ridge vent pros and cons, just so you can have them in mind if you end up making a decision on your own:

Roof Ridge Vent Pros

Having roof ridge vent installed by a professional assists in balancing out the movement of hot and cold air through the attic. The underside of your roofing system has everything to do with the life of your asphalt shingles. When hot air rises, when roof ridge vents are installed correctly, the hot air can leave the home easily, balancing out the temperatures in the attic, preventing premature shingle failure.
Throughout the colder months, roof ridge vents allow the weight of the cold air to counteract with the warmer air inside, keeping it from escaping. This controls your home and attic temperatures and reduces the cost of your utility bills!
Possum, squirrels, raccoons, mice, and rats all like to get into your home if they can find a way in. In older-style roof vents, you need to install traps or screens to prevent these pesky rodents from moving in and nesting in your attic. Roof ridge vents make it highly unlikely for rodents, birds, and other pests to find a way into your home. 
Roof ridge vents give your roofing system a smooth, finished off look that is visibly attractive and adds aesthetic appeal from ground level. The pitch of your roof will remain unchanged by the design element of roof ridge vent, but your home will be able to achieve higher energy efficiency and a healthier airflow while looking magnificent from the street!

The wind that blows over your roof naturally will draw any hot, moist air out of your attic when roof ridge vents get installed by a professional. The natural flow of air pulls air in through your eaves, causing natural air exchange as inside the attic as air passes up through the ridge underneath the ridge cap to escape back into the atmosphere.

This improves air quality in the home, prolongs the life of your roof, and prevents problems that can occur from poor air exchange in the attic such as mold, mildew, and bacteria, premature shingle deterioration, and more!

Did you know that the quality of air inside your home can to 5x to 100 x worse than the air outside? It’s true… The average people spend around 90% of their time inside every day. Nearly 2/3 of that time is in their own home. 
Indoor air pollution is rated as one of the five most hazardous environmental factors that people face today. Roof ridge vents improve the quality of your indoor air by providing constant fresh air exchange, reducing the risk of many pollution-related symptoms, like coughing and sinus infections!

Roof Ridge Vent Cons

The efficiency of ridge vents depends upon the energy-efficient nature of the home. Roof ridge vents require air movement coming in toward the vents to deliver the correct air exchange for your home. Some older houses will still require the older-style roof vents to provide the ventilation levels that they need for optimal air exchange.

If your home is in an area that is in a known path of storms with high winds, the rain could potentially blow in right in through the ridge vent. The only way to prevent the issue is to go with another style roof vent in this case.

Roof ridge vents are a more costly roof ventilation system than some other traditional roof vent methods. Anticipate your roof ridge vent installation to run around $500 or more on average if nothing else on the rest of the roof has to be touched.

Roof ridge vents and other roof vent types work more favorably in colder climates. This is just a known fact. The colder the climate, the better your attic can benefit from roof ventilation. If you live in a cooler climate like here in Minneapolis, you are in the clear here, just make sure you have rigid insulation in position to limit condensation from building up on your roof’s surface. The insulation creates a thermal barrier that works to prevent moisture damages from affecting the home.

Do Ridge Vents Leak? - Final Thoughts

To summarize, roof ridge vents can play an important role in the ventilation of your attic, and the overall health of your home in terms of having an ample amount of fresh air exchange. They cost a little bit more than traditional roof vents, but they pay off in the long run by offering a more even level of fresh air exchange, looking better aesthetically, and keeping rodents and other pests out of the house without having to take other preventative measures.
