Ridge vents and box vents are two different types of ventilation systems for roofs. Both types of vents serve the same purpose: to allow fresh air to circulate through the attic and remove excess heat and moisture.
Ridge vents are installed along the peak of the roof and run the entire length of the ridge. They are often covered with shingles to blend in with the roof. They are considered more visually appealing than box vents and they can be hidden behind the ridge cap shingles.
Box vents, also known as RVOs, are installed near the ridge line but they are put in the field or shingles compared to on the ridge itself. Box vents are usually square or rectangular in shape, and are usually made of plastic or metal. They can be painted to match the color of the house.
Both types of vents are effective at ventilating the attic, but ridge vents are generally considered to be more efficient and effective because they allow more air to circulate. However, it is important to consult with a professional roofer before making a decision on which type of vent to use, as the specific conditions of your roof and attic may influence which type of vent would be best.
