Cooker Hood Extraction: Roof or Wall?

[rosscook]

We have recently purchased a 60cm Zanussi cooker hood and would like to know the best way to duct the extract outside as we live in a bungalow. Is it better to go through the loft, then the roof with a cowl or through the wall, however we only have 100mm gap between the floor of the loft and the roof trusses if we go through the wall. Any ideas please on how and what with? thanks

Would have thought through the wall would be a lot easier & more convenient.

Any idea what products to use? Any kits? Bearing in mind the small space between the top (end) of the roof and the loft floor, as we're in a bungalow.

They do a couple of sizes in this http://www.screwfix.com/app/sfd/cat/pro or search "vents" on their site
