Ridge Vent is it Obsolete?

Ridge Vent

When it comes to roof ventilation there are as many types of ‘roof ventilators’.
All roof ventilators are developed to work in one manner or another, and a great many illusionary in that they are manufactured on cost, with little regard to performance.

Now to be fair any hole in the roof is going to let out hot air, and the size of the hole is going to make a difference.

It’s more a matter of how many you need according to their performance.

Nowadays they are considered a necessary evil, a product that has become a necessity in principle, a need, in order to comply with the building regulations or recommendations of the day.

Ridge vents are one such product, an item seen to satisfy the building code which is ironic as the building code is assembled by those who know little or nothing about roof ventilation and then are blindly followed by council authorities who know even less.

Therefore it’s up to the architect or homeowner to decide on the criteria that forms the basis of product selection.

A ridge vent provides you with a somewhat restricted opening in the roof. Nothing more, nothing less. It will relieve pressure to a degree but it’s efficiency will be dependent on the resistance within the design and the guaranteed free air.
It’s function is presumed to be sufficient to the use of the building but always falls short of expectations. Why?…because it’s a product manufactured to a price in both construction and ease of installation.

Just as there are cars and there are cars….the same applies to all products bearing the same descriptive title….roof ventilators are no different.

You either get the one that achieves your aims or you buy on price, telling yourself there’s no difference.

Then when it’s discovered that there’s a short fall in performance the developer / builder / owner seeks alternative products to supplement that which is lacking. No thought is given to the fact that you cannot successfully merge the dynamics of one type of roof ventilation with another, and so the blind just continue to follow the not so blind

Everyone’s an expert until it comes to taking responsibility, then only the trail seen is that of the wisp of smoke in the direction of the setting sun.

The ridge vent is not suited to the roof of a house and is only chosen when a diminished visual presence is sought along with the misguided belief that it will perform as expected.

Note the torturous pathway of the air volume
