I have no idea, exactly, how much pressure differential a typical leaf blower is capable of producing. Just be aware that, if you have a single pane front windshield (roughly 4' X 8') that is 4,608 square inches of surface area. IF your leaf blower is capable of blowing enough air through your roof vent to generate just 1 pound per square inch (psi) of differential pressure, that's more than 2 TONS of pressure trying to blow out your windshield. For reference, when you're "flying the friendly skies", the typical pressure differential between the inside and outside of your airplane is about 8 psi.

BE CAREFUL if you decide to try this yourself.

Take care,
YEP!! Mythbusters just did a show on that a week or so ago. They showed how just a few psi could blow a 1" thick bullet resistant door out and permanently bend it. Only took a few psi and the door started to bend and I think it went at less than 5 psi total.
