Keeping your home well-ventilated is essential if you want to avoid the formation of mold and mildew, especially in your attic.

What Does a Ridge Vent Do?
A ridge vent is a humidity and heat transfer unit found in many homes and industrial storage units. It’s especially important in hot and humid climates.
Roof ridge vents (and all other roof vents, really) are used to help circulate the air by releasing the internal air pressure with a constant flow of fresh air from the outside.
Ridge vents run the entire length of a roof. They are developed as an integrated system that includes external baffles with an internal weather filter and an under-eave venting. When constructed together, these features pack the best venting results.
Ridge vents are very affordable and long-lasting solutions that can reduce utility bill costs by making air conditioning in the attic unnecessary.
Modern venting systems are unnoticeable and blend into the roof structure. In addition, they’re pretty inexpensive. All in all, there’s plenty of benefits and no downsides to installing a ridge vent during a home renovation.

FAQ about Roof Ridge Vents
What makes roof ventilation important?
People underestimate the importance of roof ventilation. The lack of proper airflow won’t make your house collapse, but it will lead to unnecessary damage.
Here’s how proper roof ventilation helps make your home comfier:
- improves indoor air quality in the attic
- removes extra moisture, ensuring no mildew forms
- makes the job of your HVAC system easier
- prevents ice dams in the winter
- doesn’t let dry rot appear on your roof sheathing
What are good roof ridge vent brands?
Quarrix (previously known as Trimline) and GAF have whole product lines that support an entire roofing solution. GAF is by far the most often recommended ridge vent brand, and their customer ratings are overwhelmingly positive.
What do I need to watch out for when renovating my roof?
Once simple roof repairs stop bringing results, it’s time to renovate. When replacing an old system, make sure to check the integrity of the roof.
When you purchase a roofing system make sure you use the same product lines, avoid mixing brands or vent types. It is best not to do patchwork, and to replace either entire sections or the entire roof, dependent on the roofing area you need to replace.
What roof vent type is better: Continuous ridge or box vents?
Continuous ridge vents are more effective than box vents since they are installed along the entire roof ridge. They allow warm air to escape from the attic and create enough suction to work constantly. They also look better – continuous ridge vents blend into the roof’s architecture nicely since you cover them with shingles.
A boxed vent will sit on the roof providing localized ventilation only. Sometimes the airflow they produce is not sufficient, so you need to install more than one box. However, they come in a variety of designs, so a box vent can be a nice aesthetic addition to your roof.
Bottom line, continuous ridge vents are perfect for shingled roofs. Ridge vents will run along the length of the shingle and replace ridge shingles and tiles. Box vents work best with flat roof structures and require a hole in the roof to be effective.

Having a roof over your head is nice – it keeps you safe, warm, and cozy in your home. Your roof is not supposed to cause you problems, especially not something as harmful for your health as mold. Yet it happens, to almost every owner of unvented roofing.
