Installing a turbine on a house is technically problematic (a mast is simpler to deal with), it is hard to maintain there and can convey noise into the house.
The advise about having a few acres of flat land as a minimum - it is sensible, unless other options beside wind cannot be chosen.
The other good option would be community ownership of a larger turbine. This would get you the lower cost per kwh and better availability that those have
Good quality wind is high up.
