Sorry Hakan. If you were to ask me? I'd say it can't be done quite the way you would wish.
Whether you choose vertical or horizontal axis turbines, the height of the foils themselves would preclude "roof mount" once you get past two or three horsepower - 1.5 to 2 kW. Even then the degree of elevation needed for foil clearance would require a micro-tower structure on top of a stable roof system and the roof would have to be at something akin to a summit to begin with. In all probability more advantageous to separate the housing unit from the elevating tower once you get beyond a few hundred watts. If you were in the 50 kW range, I would say that you could reduce your costs by building your own tower, presuming you had an engineer and welder who didn't mind working for chips and beer on weekends. With a bit 'o luck you could trade a keg or two of Sven's Black Powder Porter to the owner of the crane company to help you get the tower and turbine vertical. 'Course, you better make sure that the crane company owner is someone you can tolerate for the next 50 years, 'cause he's gonna' be around every other weekend to admire his handiwork and swill more beer. Beyond 50 kW? You're speaking of some reasonably serious industrial construction. While 200 kW sized units are few and far between, the technology and mechanics aren't a great deal different from a 600 kW or 1.5 mW unit. 200 kW is a boatload of output. You're speaking of powering a small subdivision or the residential side of a small but posh ski resort. Me thinks that if one is considering a scale of ~200kW, it's time to call your in-law banker and a few others with not necessarily too deep pockets who are looking for a way to shelter their money from depreciation. Perhaps by the time they down the third gin and tonic they might even be thinking on the scale of megawatt? Only so much you can do on a cobbler's budget.
