Not a bad idea.. as long as it doesnt snow where you live! Ive seen a few guys get cracked cause they are the only house on the block with a big melted patch of snow on the roof! Venting straight up is great tho.. especially for smell.. gives it a chance to dissipate before it hits any noses ;)

i never thought of that, with the snow.i thought maybe when its cold the hot air mite b visible?...would it? also thought maybe about hanging ballast in between help keep cool ?:thumbsup:
