Why use Evolution

ridge vents?

Evolution solves some problems and offers some benefits that current ridge vent designs cannot.

Evolution

This is a fine example of a ridge vent installation.

It is uniform, nailed well and runs the complete length of the ridge.

It will function properly and preserves the aesthetic value of an attractive roof.

This quality installation is however the exception.

More installations look like this.

This is a fairly typical installation.

A closer view of a typical Installation.

Many ridge vents are installed incorrectly.

Over nailed and not continuous. This is very common.

This job was run to the edge on top and not on the lower section. It is also nailed poorly.

Over nailed and uneven.

Sometime it’s contractor error. Sometimes the product is very difficult to install evenly.

Not Good.

Ridge vent installation has gone on like this for years.

Evolution can solve this.

1. Evolutionary design approach.

We have developed a ridge vent that doesn’tshow on the front of the home.

This is the Evolution ridge vent as seen from the front of the home.

This is the same vent from the back of the

house.

Ridge vents protruding on both sides can create aesthetic and installation problems.

Aesthetic problems because of over nailing causing the vents to wave.

Aesthetic problems because, as we have seen, the vents must be run the full length of the ridge

or they are highly visible.

Installation problems creating aesthetic problems because if the vents are not cut into the junction point they are highly visible.

In fact this roof shows many of the problems.1. It’s over nailed

2. It’s not run the full length.

3. It isn’t run to a junction point.

The Evolution can solve or diminish all of these problems.

The Evolution vents from one side of the home. The choice can be made for aesthetic reasons,

the vent will function the same.

There is only a flange on the other side of the vent. So all that is seen from that side of the

installation is the ridge cap. Like there was no vent at all.

This is how the ridge cap looks with the flange underneath it.

You can’t over nail the flange.

In fact you don’t nail the flange.

Unless you want to.

Why does the product have a flange?1. The flange is a safety feature.

In the event there is a cap failure the flange will help protect the home.

2. The flange may cover the slot opening from a prior ridge vent application.

The vent side looks just like any standard application.

Having a flange on one side solves several aesthetic problems.

1. No over-nailing

2. If the product is not run the full length of the ridge it is not as aesthetically detrimental as typical ridge vents.

3. This also means that it doesn’t always need to be cut into a junction point because the vent installation only impacts one side of the ridge.

How would this home fare with Evolution?

You could pick the side you wished the vent exposed from.You could pick for aesthetic reasons or performance reasons.

Perhaps these.

The junction points would not be an issue.

Better aesthetics.

Give the homeowner better aesthetics.

Lower labor costs.

Only one slot to cut.

Only one side to

nail.

Only one side to nail.

The ridge cap lines up with the vent opening on one side of the vent.

Then extends as far down on the other side as cap width determines.
