I'm currently finishing two ovens with offset flues. I believe there are some advantages doing it this way. Firstly the oven can be located under cover, the mouth certainly which is the most important part to keep dry. Secondly it negates the problems of penetrating the roof, namely sealing problems, having to use a double flue and roof corrosion around where the flue penetrates from corrosive emissions. The drawback is the look of the thing, I'm undecided about that, it does look a bit "industrial" The extra bends also create some extra cost and installation time.
