cooker hood positioning problem

[seneca]

Got a bit of a problem with siting a cooker hood. The problem is there are no outside walls near to the cooker and I don't want to rearrange the kitchen. I was thinking or getting a hood that recirculated the air, but I 'd rather have one that extracted. I've put together a diagram showing the layout. There are 2 possible runs that I have highlighted with a dark line and the grey area is the house. The non-grey area has a flat roof that I could use, but rather not have to get a watertight seal around a chimney. I have yey to investigate the possibility of running the outlet pipe through the space in the flat roof.

Did not know how to post pic so look at this link

hi,is the flat roof lower than where the flu would come out of the wall if it is no problem with that.if it is not it is always best to have the flu at the back of the house,possibly run a flu inside the outhouse leading to back wall.

seneca, all you had to do was copy / paste the [net] "line" as you see it.[/net]

The flat roof is single story (about 50cm I think.)
Didn't want to enter the utility room because there is a lot of piping (water, CH) in there. I didn't draw it in, but there is a garage behind the utility romm as well. The dark lines I drew seemed to be the obvious routes to me. I'm just worried that they are quite long, so was wondering if there were any other ideas.
