If not working or sitting in the garage, the garage screen door is being used to ventilate the garage. The attic door is a fire-block by code. If you leave it open and happen to have a fire in the garage, it will spread to the entire house quickly. With the attic door open and if a fire occurs, you may void your insuance. You can install a garage ceiling fan (coolmygarage.com) that will pull the cool air up through your attic and out the roof vents. The cool my garage exhaust fan also has a thermo damper that automatically closes when fire occurs. My garage attic never above 105, with the thermostat control.
