The purpose of having roof vents are the following; preserving the life of the roof, reducing the moisture inside the roof, maintaining the right ventilation inside the roof to avoid molds and moisture and for aesthetic and style purposes as well.
Birds nests or squirrel nests on the roof in the vents
It allows the drains to flow freely and the stench of the sewer to be sent to the highest point in the roof. That is why p-traps are installed, so the sewer gasses go to the roof vents and not through the water in the traps.
Roof vents are used to ventilate humid air out of the attic area of the house to increase the air conditioners ability to cool air down or the heaters ability to heat the air. Roof vents can also suck humid air into the attic and eventually rot the roof over time if the air flow is off balance though.
Gable vents are actually counter productive when used with ridge vents. It is better to have ventilation at the soffits which will create a draft drawing in cooler air and exhausting it through the ridge.

It is recommended that you have both intake vents and exhaust vents. Most do it yourself sites recommend soffit vents for the intakes. Exhaust vents vary in both type and cost. For smaller houses the most recommended type is a ridge vent system. The number you will need depends on the square footage of your attic.
