Key Differences Between Shingle Vent II And Cobra Ridge Vent

Shingle Vent II Vs Cobra

For starters, these two products are from different manufacturers. Shingle vent II is the product of Air Vent.

Cobra is a product from GAF. Air Vent ranks among the top experts in attic ventilation. GAF came on the scene in 1886 and Air Vent in 1990.

But the years between them do not give GAF an edge over Air Vent product quality. The shingle ridge vent is a shingle-over ridge vent.

Its design has a unique external baffle that boosts airflow in the attic. But, Cobra is a roll ridge vent.

It comes in a roll and looks like a rubber rug. Both ridge vents need ridge caps after installation. But you can still tell them apart.

When you study the Shingle ridge vent, you will notice a layer of foamy fabric underneath. That layer is the internal weather filter.

The weather filter is non-clogging and helps to keep rain, snow, dust, and insects out of the attic. Cobra does not come with a distinct weather filter.

So, it does not keep stuff out of the attic like Shingle Vent II. Another difference is in their dimensions. The Shingle ridge vent only has an option for 12 inches in width.

It comes in ten 4-foot pieces (40 feet) that allow good net free area. Cobra has options for 20 and 50 feet of rolled ridge vent.

It is available in 8, 10, 10.5, 10.75, and 12 inches in width. More common in the market is the 20 feet option.

It does not allow much net-free area.

Then we look at the materials used for the two products. Polypropylene is the material used to make shingle vent II.

Polypropylene degrades after 20-30 years. So, it is less toxic than most plastics. Polypropylene makes shingle vent II resistant to moisture and chemical erosion

But, the material used for Cobra is Composite Fiber. This makeup helps it resist deformation and makes it flexible.

Due to the contrast in their makeup, the shingle ridge vent is more durable than the cobra ridge vent.

Cost Analysis Of Shingle Vent II And Cobra

Despite the efficiency of a ridge vent, the defining factor for buying is its price. While proper attic ventilation is needful, you get a hiccup breaking the bank for a ridge vent exhaust.

For the pocket-friendly option, you can turn to Cobra. You can get a sweet deal for the 20′ x 10.5″ Cobra vent black pack for under $60.

That is a fair deal for 20 feet of rolled ridge vent! Due to the superior design of the shingle vent II, it costs more than twice the price of the Cobra vent. That should not scare you.

Shingle Vent II is more than a ridge vent exhaust. Also, the shingle vent measures up to 40 feet compared to 20 feet for Cobra.

Hence the wide gap in their prices. Shingle vent II has two options on Amazon with nails and without nails

There is only a difference of a few dollars between them. It is better to go for the one without nails. It costs about $160.

If you compare Shingle Vent II and Cobra prices, Shingle seems lavish. But look at it this way; Shingles Vent II gives you twice the length of Cobra and more features.

Why not get two 40 feet Cobra vent black packs at $120 and save $40? Well, 40 feet of Cobra would not perform as well as 40 feet of shingle vent II.

So, the shingle vent II seems pricier than a cobra, but it is the better deal in the long run.
