FWIW: Rooftop installation probably requires a stronger structure than the average building will provide. While they are less stressful than the HAWT design, they still reflect a big torque load on their mounting, and a vibration environment. I say this without any experience in VWT's, but experience in radar antenna servomechanism design.
The rooftop ones I've seen are only a handful of feet tall.
