Venting Into Roof Space

I have set up a 2m x 2m tent which i intend to flower in and up until today i was going to make another big hole in the side of the garage wall ie i have a 12 fan that i plan to use for extraction of hot air produced by 2 600w hps lights ive since thought to myself would i get away with venting straight up into the roof space above or would it. It is likely that even of an air change per hour would be adequate for an attic space but each ventilation design must take into account the type of roof the design of the building and the site environment. I was thinking of using a straight pvc pipe to create a horizontal run leading towards the roof and then somehow terminating it at the eaves.
