Ridge vents run the entire length of a roof, and they have evolved into an integrated system that includes external baffles with an internal weather filter and an under-eave venting. This trio, when constructed together, pack the best venting results.

Ridge vents are very affordable and long-lasting solutions that can reduce cooling costs by relieving the use of air conditioners. Modern venting systems are unnoticeable and blend into the roof structure. A ridge vent needs access to a good intake of fresh, cool air in order to expel hot, humid air; essentially, they need a balanced equal flow of exhaust and intake to work properly.

Here we introduce you to the leading ridge vents.

We built this guide using three factors; type, dimensions, and material.

Bottom Line

This is a great ventilation system for homes as well as warehouses and commercial buildings. In fact, most Florida homes have this venting system installed to prevent the humidity from fouling up the attic air and creating mildew, mold, and corrosion of metallic parts.  When buying this brand, make sure you  match it to other parts of the same company.




It is imperative to purchase a product from a reliable source, that is why this list is short, it gives you two main brands to choose from, and they are, in our opinion, the best and most reliable brands on sale today.

Trimline and GAF have whole product lines that support an entire roofing solution when you purchase a roofing system make sure you use the same product lines, its best not to mix them up. When replacing an old system, check to see the integrity of the entire roof. It is best not to do patchwork, and to replace either entire sections or the entire roof, dependent on the size you need to replace.

Continuous Ridge or Box Vents?

Continuous ridge vents are more effective than box vents since they are installed along the entire peak of a roof’s ridge. They allow warm air to escape from the attic and create enough suction (vacuum) to work on a constant basis. You only need to install one unit, and they blend into the roofs architecture.

A boxed vent will sit on the roof providing localized ventilation only, sometimes the vacuum them produce is not enough, so you need more than one box, and as such, they clutter up the 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 fit over for effectivity.
