Roof ventilation is needed. The roof needs cooling from the inside. End vents help - end fan that turns on by thermostat is great. Use only when it is needed. Top ridge vent with eave vents is great also.

You should always check your installation guidelines for each roofing product. Ventilation isn't just a clever move.
MOST residential roofing manufacturers will void the warranty of your roof if you don't have the proper type and amount of ventilation installed.
