Ridge vents are part of the system, and its easy to mess up.
Regardless of what you go with on a vent, you need a way to let air in and let it out.
Check your soffit vents (if you have them) make sure they are not plugged with insulation.
If you have gable vents, you don't want the ridge vent close to them. It sets up a circulation zone and what comes out goes right back in.
You don't want unventolated spaces in the attic.
If you have a cut up roof line pay attention to how the attic is set up. Do you have paths for air to get into and out of every roof, or do you have roofs that have no ventilation?
Proper roof ventilation keeps the shingles cooler, and they last longer.
Worth a few bucks to do it well.
