Continuous Venting Ridge vs Static/Box Vents: Which is better?

by Jul 31, 2018

Regardless of the situation, all roofs need to be properly ventilated. There are a few differences between Static vents and Continuous Ridge Vents. Deciding which one to put on your roof depends on which one better fits the type and design of your roof. Either option requires adequate intake ventilation.

Historically, the most common type of roof ventilation is the “Static” or “Box” vent. This type of vent is exactly what it sounds like: box shaped vents that remove damaging heat and moisture from the attic. One reason that they are so popular is because they provide a very economical way to ventilate your attic. Box vents are ideal whenever you have an open attic. The vents must be placed very close to the ridge of your roof. Installation is simple, quick, and easy.

Continuous venting ridge is a type of ventilation that allows outward air flow along the ridge or peak of a roof. An opening is cut along the desired ridge line and the continuous ridge vent is laid over the opening and sealed with standard ridge cap shingles. Having the entire ridge line open for venting allows more air to flow out and, in turn, will allow better ventilation of the attic space. Installation is more difficult, time consuming, and expensive; but the performance and more finished look speaks for itself.

Roofing manufacturers’ warranties require a minimum of one square foot of ventilation for every 150sf of attic space for traditional systems, but only one square foot of ventilation for every 300sf when the ridge vent system is used. That is a good indication of the difference in efficiency. Using the continuous venting ridge system, when installed properly, can prolong the life of your roof and cut down on energy costs. When applicable, Ridge Vent is the way to go!
