Well, the short answer is "Yes," but there are reasons. Here are a few:

The Importance Of Ventilation

Good ventilation creates a cooler attic in the summer
An overheated attic, combined with moisture, can be damaging to roof decking and roofing shingles, causing them to distort and deteriorate prematurely.
Good venitlation creates a drier attic in the winter and helps prevent ice dams.
Good ventilation serves two main functions:
- Moves hot air next to the roof deck out of the attic in the summer.
- Dilutes and removes the moist air in the winter before it can cause damage.

Different Types Of Ventilation

There are many different types of roofing ventilation. Each has it's advantages and drawbacks:

Static Vents - The least expensive but only provides ventilation in the immediate area where they are installed.
Gable Vents - The wind must blow directly into one vent in order to get the air flowing across the attic and out the other vent.
Turbine Vents - Experience the same problems as the static vents but generate a greater airflow that the static vents.
Power Fans - The provide a high airflow. However, they take energy to operate so they create an ongoing expense. Also, fans controlled by a thermostat will usually operate only in the summer. These fans do nothing to remove the moist air that gets in the attic during cold months.

The Most Ventilation For The Money

A ridge vent is positioned along the entire length of the roof peak. In addition to being excellent exhaust vents, ridge vents blend in with the roof line, making a more attractive home. Years of research has proven that ridge vents with external baffles, combined with undereave venting, is the most efficient and effective system you can install.
